IES UPDATE<br />
Message from the President<br />
The number of Green Mark-certified buildings in<br />
Singapore has crossed 1000, included among which<br />
are 100 buildings which have received the highest<br />
Green Mark Platinum rating.<br />
These figures clearly show the commitment with<br />
which the republic is addressing the serious issue of<br />
global warming and carbon emissions.<br />
With several of its initiatives and incentives already<br />
in place, the government is going even further,<br />
by promoting collaboration between the public and private sectors in the area of<br />
research on green buildings.<br />
As a first step, the Agency for Science, Technology and Research (A*STAR), Building<br />
and Construction Authority (BCA) and the Ministry of National Development<br />
(MND) have jointly awarded funding for nine research projects on green technologies<br />
that could help buildings save energy.<br />
However, in order to move towards greater sustainability of all human activity, there<br />
is the need to conserve all resources which include, besides energy, also water, raw<br />
materials etc, as well as recover, recycle and reuse as much as of these resources as<br />
possible.<br />
With increasing urbanisation taking place all over the world, there is the realisation<br />
that an integrated approach is necessary to achieve sustainable growth and a better<br />
quality of life.<br />
This theme will be emphasised at the Singapore International Water Week 2012,<br />
World Cities Summit 2012 and CleanEnviro Summit Singapore 2012. The three events<br />
will be held concurrently from 1 to 5 July 2012, at the Sands Expo and Convention<br />
Center, Marina Bay Sands, Singapore.<br />
The Singapore International Water Week 2012, World Cities Summit 2012 and<br />
CleanEnviro Summit Singapore 2012 will attract participants including product<br />
manufacturers, specifiers, professionals, government agencies and others, from all over<br />
the world.<br />
It has been with great honour that I have served the members of IES for the past two<br />
years as President. I have to thank the rest of the Council, the IES secretariat and the<br />
members for their assistance and contributions over that time. My gratitude goes out<br />
to everyone who has given their time and effort in helping IES move forward. After<br />
the AGM in May, I am handing over the role of President to Prof Chou Siaw Kiang.<br />
I believe that everyone will give their full support to the new Council and I am certain<br />
that under Prof Chou’s guidance, IES will continue to go from strength to strength.<br />
Thank you one and all.<br />

Seminar on Behaviour Based Safety<br />
implementation in construction<br />
On the morning of 13 April 2012, Er. Ho Siong Hin welcomed<br />
the audience to a seminar on ‘Behaviour Based Safety (BBS)<br />
Implementation in Construction Industry’ at NTU@one-north<br />
Executive Centre. The talk was organised by the IES Health &<br />
Safety Engineering Technical Committee.<br />
Addressing the 103 participants who had signed up to listen<br />
to the talk, Er. Ho stressed the importance of a BBS approach<br />
towards understanding the underlying causes of accidents and<br />
how BBS can help decrease the accident rate in the construction<br />
industry. He went on to describe BBS as a concrete platform to<br />
achieve the National Workplace Safety and Health (WSH) 2018<br />
vision of ‘A safe and healthy workplace for everyone.’<br />
To get the national fatality rate to less than 1.8 per 100,000<br />
workers in 2018, the WSH Council’s vision has defined four<br />
strategic outcomes:<br />
1. The reduction in WSH incident rates.<br />
2. WSH being an integral part of business.<br />
3. Singapore being known as a renowned Centre for Excellence<br />
for WSH.<br />
4. A progressive and pervasive WSH culture.<br />
After Er. Ho’s introduction, four speakers shared their<br />
experiences in BBS as well as in promoting the use of BBS as<br />
an important tool at the workplaces of the audience members.<br />
The four speakers were Mr Andrew Tan Hock Seng, Manager<br />
(Safety) from the Safety Division of the Land Transport<br />
Authority (LTA); Dr Evelyn Teo Ai Lin, A/Prof and Director of<br />
External Affairs at the Department of Building, School of Design<br />
and Environment, in NUS; Mr Seow Min Fook, who formerly<br />
worked as an Operations and Safety Manager in the petroleum<br />
industry; and Mr Yeo Kim Hock, the Divisional Safety Manager of<br />
Gammon Pte Ltd.<br />
Mr Tan spoke of the history of WSH maturity through the years<br />
and the background for BBS implementation while Dr Teo<br />
explored the cultivation of a safety culture to integrate the BBS<br />
approach as part of normal operation. Mr Seow and Mr Yeo<br />
both spoke about their experiences in WSH and shared the<br />
valuable practical knowledge of implementing the procedures<br />
of BBS during their careers. After speaking, each of the speakers<br />
was given a token of appreciation by Mr Jason Oh, Chairman<br />
of the IES Health and Safety Engineering Technical Committee.<br />
Speaking to ‘The Singapore Engineer’ magazine after the talk,<br />
Mr Tan said, “LTA’s view is that BBS is a necessity because ‘at<br />
risk’ behaviour is predominant at construction worksites and we<br />
want all our contractors to implement it wholeheartedly. Despite<br />
having proper management systems, the requirements of the<br />
law and the requirements of WSH tender specifications in place,<br />
accidents still happen. The problem is largely behaviour-related,<br />
so you need to find a way to arrest such ‘at risk’ behaviours<br />
Mr Andrew Tan from LTA spoke about<br />
the importance of BBS implementation.<br />
before any incidents happen. BBS is a powerful process that can<br />
help identify ‘at risk’ behaviours before incidents happen and at the<br />
same time strengthen the WSH culture within an organisation.”<br />
According to Mr Tan, LTA started looking into BBS in 2010 as a<br />
way to improve its WSH performance at worksites. LTA did a<br />
pilot BBS implementation on two of its heavy civil <strong>engineer</strong>ing<br />
projects and achieved very good results. LTA has gone on to<br />
facilitate BBS implementation for its contractors by giving them<br />
training in BBS as well as through the usage of an internetbased<br />
platform for monitoring and analysing behavioural data.<br />
He added, “The main hurdle that the contractor needs to cross<br />
within themselves is the commitment that they can deliver<br />
within their own company. We are currently pushing for all of<br />
our existing projects to implement BBS and it will be mandatory<br />
for all future tenders on our projects.”<br />
The move to include a BBS component in the contracts from<br />
LTA, which is a prime government developer, is helping to<br />
spread the use of BBS among contractors. Dr Teo of NUS said,<br />
“For contractors to bid for LTA projects, they must have a BBS<br />
component or they will not be selected. You can see a lot of<br />
contractors are now coming on board and want to learn more<br />
about BBS to implement it on site.”<br />
Dr Teo also reiterated Mr Tan’s point in her observation that<br />
when companies go through the motions of using BBS just based<br />
on requirements, it made<br />
it very hard for people on<br />
the ground to actually<br />
implement it. She added,<br />
“BBS is for contractors who<br />
already have a very good<br />
safety culture. Without that,<br />
it is very hard to implement<br />
a BBS programme. The top<br />
management has to be very<br />
committed. These are the<br />
two critical factors you must<br />
have to implement BBS<br />
on site.”<br />
Dr Evelyn Teo from NUS described the<br />
safety culture needed to implement BBS.<br />
Mr Seow Min Fook spoke from experience<br />
on how BBS works in practice.<br />

“We all know that good safety culture will result in good safety<br />
performance,” said Mr Seow, whose experience in implementing<br />
behaviour science in safety stretches back to his early work in<br />
refineries in the late 1970s, where he was influenced by the<br />
forward thinking of managements.<br />
He described what it would take to build a good safety<br />
culture that would support BBS. “You cannot get to a safety<br />
culture immediately. How do you change culture? How do you<br />
change attitude? What you can see is behaviour. The sum total<br />
of behaviour becomes attitude and the sum total of attitude<br />
becomes culture. So you work on the behaviour aspect in<br />
order to attain a safety culture where people exhibit more safe<br />
behaviour than ‘at risk’ behaviour”, said Mr Seow.<br />
He ended by saying that he was glad that the authorities<br />
are now pushing companies to implement BBS on a formal<br />
basis because not all of them are fortunate enough to have<br />
had forward-thinking leaders who have already incorporated<br />
behaviour science as part of their safety culture.<br />
Mr Yeo’s experience with implementing BBS at his company,<br />
Gammon, was also a top-down process. “We have a history of<br />
how we address safety matters within our group and we started<br />
by training all of our top management, our managers and our<br />
supervisors. After this phase, we engaged a consultant who said<br />
it was time to go to the next level.”<br />
Health & Safety Engineering Technical<br />
Committee looking for new members<br />
One of the three IES committees honoured with the IES<br />
Outstanding Committee Award at the IES Appreciation Night<br />
2012 was the Health & Safety Engineering Technical Committee<br />
(HSE TC). Chaired by Mr Jason Oh, the mission of the Committee<br />
is to help achieve the WSH 2018 Vision of reducing fatalities. The<br />
HSE TC is currently expanding and looking for volunteers to join<br />
the committee. In particular, they are reaching out to members<br />
who are in other industries to tap into their expertise in those<br />
areas. The committee is divided into 5 major sub-committees:<br />
• Design for Safety, chaired by Mr Chan Yew Kwong.<br />
• Heavy Machinery, chaired by Er. Chui Heng Tak.<br />
• WSH Research, chaired by Dr Goh Yang Miang.<br />
• Media & External Agencies, chaired by Mr Bhupendra Singh.<br />
• WSH Events / Conference, chaired by Ms Png Mui Kee.<br />
The Design for Safety Sub-committee is currently working<br />
with architects and consulting <strong>engineer</strong>s from design firms by<br />
looking at the safety and health aspect of a new building from<br />
the design stage, and from there, to building the building and<br />
maintaining and repairing it. By looking at the potential safety<br />
and health issues downstream, they want to be able to enhance<br />
the design and eliminate safety issues or mitigate the risk by the<br />
implementation of safety features.<br />
At the moment, the Heavy Machinery Sub-Committee is looking into<br />
organising specialised courses for training workers in crane operation<br />
to make sure they are able to maintain and operate them safely.<br />

All four speakers received Tokens of Appreciation from Mr Jason Oh (right),<br />

The opportunity arose for them to implement the BBS system as a<br />
trial project during the construction of the Sentosa Boardwalk in<br />
2010. This was because they had recorded 15 cases of accidents<br />
in a span of six months. A comparison between the six months<br />
when the trial project to implement BBS was in effect and the<br />
previous six months when the accidents occurred showed that<br />
implementing BBS was effective in preventing accidents.<br />
Mr Yeo put the success of the BBS approach in the trial project<br />
down to three factors. “A lot of effort was put into how people<br />
were approached to get the buy-in, to convince the workers that<br />
in the future they have to do this in a better way. An incentive, in<br />
the form of a monthly cash reward, and peer pressure, are also<br />
keys to success,” he said.<br />
The WSH Research Sub-committee is currently focusing on two<br />
projects. One is research into system design and the other is the<br />
creation of a book covering past accidents in Singapore.<br />
The Media & External Agencies Sub-Committee members<br />
represent IES in general <strong>engineer</strong>ing safety standards committees.<br />
The main role of the WSH Events / Conference Sub-committee<br />
is to create awareness in <strong>engineer</strong>ing safety and health.<br />
They conducted the recent BBS seminar and are currently<br />
collaborating with the Society of Loss Prevention (Singapore)<br />
to conduct a talk.<br />

Laurel leaves, which represent creativity<br />
and achievement, have been used in the<br />
logo of the CoF to highlight the fact that<br />
it will be a training ground for grooming<br />
and educating the next generation of<br />
‘master <strong>engineer</strong>s’. The green colour<br />
of the leaves symbolises ‘youth’ among<br />
whose ranks are budding <strong>engineer</strong>s.<br />
Creativity<br />
Laurel leaves are said to communicate the spirit of prophecy and<br />
poetry. They were commonly put under pillows at night to gain<br />
inspiration through dreams and their intoxicating properties are<br />
associated with prophetic and poetic inspiration.<br />
Achievement<br />
Laurel leaves have long been a symbol of victory. They were<br />
given as a symbol to the winners in Pythian games. Freemasons<br />
consider the laurel to signify the expectation of success in their<br />
search for the ‘True Word’. In the Bible, the laurel is an emblem<br />
of prosperity and fame. In Christianity, it is said to symbolise the<br />
resurrection of Christ and the triumph of humanity. It is also the<br />
source of the words ‘Baccalaureate’ and ‘Poet Laureate’.<br />
Red, blue and yellow<br />
These three colours in the logo represent the three major<br />
disciplines - Civil, Mechanical, and Electrical Engineering.<br />

IES UPDATE<br />
Tapping the untapped potential<br />
Er. Lim Soon Hock, Dean of the CoF,<br />
speaks glowingly on the strengths of IES.<br />
“We can find, just from the membership<br />
base within the institution, a huge<br />
reservoir of talent, knowledge, expertise<br />
and experience”, he said.<br />
According to him, the issue is not one of<br />
capabilities.<br />
Er. Lim Soon Hock.<br />
“The challenge we have in front of us is how to mobilise<br />
and organise all these capabilities to increase and expand<br />
our capacity to champion the <strong>engineer</strong>ing profession and<br />
to be the heart and voice of the <strong>engineer</strong>ing community.<br />
Much more needs to be done to promote and nurture the<br />
<strong>engineer</strong>ing profession to the esteemed and respected stature<br />
of yesteryears. Engineers must be seen and be heard in<br />
contributing to the economic progress and social well being<br />
of Singapore, which many are already doing, but not noticed”,<br />
Er. Lim said.<br />
“In a nutshell, we are talking about how we can leverage the<br />
CoF to build a larger capacity from the huge reservoir of<br />
capabilities that we have within IES, to serve the <strong>engineer</strong>ing<br />
community and our nation at large”, he added.<br />
“When the CoF launches its programmes in 2012, it hopes to<br />
be able to leverage on the capabilities from all IES members,<br />
so as to also empower the next generation of <strong>engineer</strong>s to<br />
champion the art and science of <strong>engineer</strong>ing”, Er. Lim said.<br />
He pointed out that IES Fellows are members with deep, wide<br />
and respectable experience, who are sitting at the apex of the<br />
<strong>engineer</strong>ing pyramid.<br />
“When we are able to harness the capabilities of our existing<br />
and future pools of Fellows, to mentor younger <strong>engineer</strong>s, it will<br />
hopefully serve to inspire and challenge our young <strong>engineer</strong>s<br />
to go beyond what they have learnt and seen”, Er. Lim said.<br />
Vision & Mission<br />
The CoF’s vision is ‘to be the leading champion on the art<br />
and science of <strong>engineer</strong>ing and the developer of <strong>engineer</strong>s of<br />
the future’.<br />
“Being the leading champion means collectively leading by<br />
example - not by words, but by actions. It is critical that no<br />
efforts are spared to try to win back the high respect and<br />
esteem for <strong>engineer</strong>s, which unfortunately has declined over<br />
the years, as compared to the levels that the profession had<br />
enjoyed previously. To support the developmental needs of<br />
Singapore, we must encourage more of our brightest and<br />
smartest students to take up <strong>engineer</strong>ing, to avoid a hollowing<br />
out of <strong>engineer</strong>ing talent. This would be disastrous to our<br />
economy, should it happen”, Er. Lim said.<br />
“We need to go beyond the science of <strong>engineer</strong>ing to include<br />
the art of <strong>engineer</strong>ing. This means not confining ourselves to<br />
the nuts and bolts, but to encompass other aspects, such as the<br />
human side of <strong>engineer</strong>ing and other non-<strong>engineer</strong>ing fields.<br />
The CoF is the ideal platform to achieve this”, he added.<br />
“Here, when we talk about art, we are talking about the holistic<br />
practice of <strong>engineer</strong>ing and applying it, and the training of<br />
<strong>engineer</strong>s so that they are able to apply what they have learnt<br />
in a broad spectrum of fields and areas beyond <strong>engineer</strong>ing<br />
- it could be in business, government, public service, wealth<br />
creation or even community service”, Er. Lim said.<br />
He believes that <strong>engineer</strong>s of the future must be able to play<br />
a major role in all sectors of industry. Fellows can be changemakers<br />
to help shape this <strong>engineer</strong> of the future. Er. Lim intends<br />
to tap on the collective wisdom of Fellows to achieve this. In<br />
his view, the <strong>engineer</strong> of the future is likely to have a ‘T’ profile.<br />
He has specialisation in one area, but at the same time has the<br />
versatility to be involved in a broad spectrum of activities.<br />
Er. Lim believes that these <strong>engineer</strong>s must be able to play a<br />
major role in wealth creation in Singapore.<br />
“Engineers are great inventors and great creators. We are not<br />
just builders of roads, buildings and other hard infrastructure<br />
but also great inventors of consumer products. In Singapore,<br />
there are many successful CEOs, businessmen, entrepreneurs,<br />
politicians, civil servants, lawyers and even high court judges as<br />
well as community leaders, who are outstanding role models<br />
for the <strong>engineer</strong>s of the future. They are all making an impact<br />
on society and on our economic progress and prosperity.<br />
The <strong>engineer</strong>s of the future should possess the versatility and<br />
intelligence of many of them”, he said.<br />
Er. Lim pointed out that like all evolving organisations, whilst<br />
the CoF pursues its current vision and mission, these will<br />
evolve over time, as more experience and knowledge are<br />
gained operationalising it. Accordingly, the vision and mission<br />
will be refined and reshaped over time.<br />
Projects<br />
The CoF has started to identify projects to engage IES Fellows.<br />
Fellows are also encouraged to suggest and recommend<br />
projects or ideas for the CoF to consider and to implement, in<br />
pursuit of the vision and mission.<br />
One project is the MOU which IES has recently signed<br />
with JTC, which the CoF has been chartered to carry out.<br />
Er. Lim believes it is a great example of the kind of strategic<br />
partnership that CoF would like to forge. CoF will contribute<br />
the talent, knowledge and expertise which JTC requires, to<br />
complement its existing capabilities, not just for current<br />
projects or <strong>engineer</strong>ing solutions, but also to cater to future<br />
<strong>engineer</strong>ing challenges and solutions, such as those relating to<br />

greening, sustainability, power generation etc.<br />
“From the operational standpoint, this partnership makes<br />
sense because IES can focus on strategy and policies, while the<br />
College can focus on implementation and leveraging on the<br />
knowledge and talent of our Fellows”, said Er. Lim.<br />
Another project that is being evaluated is the implementation<br />
of a mentorship programme for young <strong>engineer</strong>s and<br />
practising <strong>engineer</strong>s who want to start their own businesses.<br />
They can approach the CoF for mentors who are experienced<br />
entrepreneurs and who would be able to provide the necessary<br />
guidance and advice. It would be modelled around the medical<br />
practice. The CoF aims to play a vital role in developing and<br />
nurturing the ‘Entrepreneurial Engineer’ to contribute to the<br />
wealth creation of Singapore.<br />
The CoF will also be able to assist <strong>engineer</strong>s who encounter<br />
problems in their professional work and in the practice of<br />
their professions. For example, when an <strong>engineer</strong> runs into<br />
a complex <strong>engineer</strong>ing problem, he can turn to the CoF<br />
for help. The CoF will connect the <strong>engineer</strong> to a retired<br />
Fellow who has tremendous experience and expertise,<br />
for the solution.<br />
Er. Lim would also like to see a task force being set up to look<br />
into the re-<strong>engineer</strong>ing of the <strong>engineer</strong>ing profession.<br />
‘We must have more of our brightest and smartest students<br />
enroll in <strong>engineer</strong>ing, to reverse the current trend, which is a<br />
cause for great concern. While some would pursue <strong>engineer</strong>ing<br />
when they graduate, it is perfectly alright for others to apply<br />
their training in other fields. Our goal must be to achieve a<br />
large share of <strong>engineer</strong>s in leadership positions in all industries,<br />
be it in the public, private or people sectors”, he said.<br />
Er Lim added, “These are just some ideas that the College<br />
has put together in the hope of reaching out to the wider<br />
<strong>engineer</strong>ing community. We are currently working out the<br />
processes and logistics. We welcome feedback and suggestions<br />
on how we can make this a reality. It is all about mobilising and<br />
organising capabilities which we have in significant numbers, to<br />
build and increase the capacity, beyond what we have today, to<br />
support the <strong>engineer</strong>ing profession”.<br />
“The world that we live and work in is very different from<br />
what it was in the past. Things move and change very quickly.<br />
There are also many complex problems, some of which are<br />
national in nature, for example the floods and the recent<br />
SMRT breakdowns. Engineers should leverage on and seize this<br />
opportunity to solve many of these problems and challenges.<br />
Fellows, in particular, can contribute to the development of<br />
a vibrant and technology-rich <strong>engineer</strong>ing community for the<br />
sustainable economic development of Singapore. Engineers<br />
can be in the forefront of many exciting developments and<br />
changes in Singapore, the region and the rest of the world.<br />
CoF would like to be the enabler of this”, Er. Lim said.<br />

Marina Bay Sands - application of prescriptive and<br />
performance-based fire protection concepts<br />
Arup, the global design, <strong>engineer</strong>ing and business consultancy, received the National Fire<br />
& Civil Emergency Preparedness Council (NFEC) Fire Safety Design Excellence Award<br />
2011, for its outstanding work on Marina Bay Sands.<br />
The awards, jointly organised by NFEC and the Singapore Civil Defence Force (SCDF)<br />
as part of the Fire Safety Asia Conference 2011 which was held in Singapore, from 12 to<br />
14 October 2011, give recognition to individuals and organisations, for their contribution<br />
towards achieving a high standard in fire safety design in Singapore.<br />
KEY FACTS ON MARINA BAY SANDS<br />
• Situated on 15.5 ha of land with 581,400 m 2 of Gross Floor Area.<br />
• Hotels: three 55-storey towers with 2,561 luxury rooms<br />
and suites, capped by the Sands SkyPark, the world’s largest<br />
cantilevered observation deck.<br />
• Expo and Convention Halls: 130,000 m 2 of flexible convention<br />
and exhibition space, featuring Southeast Asia’s biggest<br />
ballroom.<br />
• Shopping: 80,000 m 2 of retail and dining space.<br />
• ArtScience Museum: lotus-inspired gallery with nearly 800 m 2<br />
of exhibition space.<br />
• Theatres: two state-of-the-art theatres with a total of 4,000 seats.<br />
INTRODUCTION<br />
Conceived by Sheldon Adelson, Chairman and Chief Executive<br />
of Las Vegas Sands Corp, and designed by world-renowned<br />
architect Moshe Safdie, Marina Bay Sands integrated resort is an<br />
exciting new development at the heart of Marina Bay.<br />
It comprises three luxury hotels, a casino, convention and<br />
exhibition facilities, and theatres. The three hotel towers are<br />
crowned by the spectacular Sands SkyPark on the 57 th storey.<br />
Marina Bay Sands integrates Singapore’s prestigious waterfront<br />
promenade with retail, dining and entertainment facilities, and<br />
breathtaking city views, thereby transforming Singapore’s skyline<br />
and its tourism potential since its opening on 27 April 2010.<br />
Marina Bay Sands poses particularly challenging fire and life safety issues due<br />
to the large numbers of people accommodated within the development from the<br />
basement levels right up to the Sands SkyPark on the 57 th storey. These have<br />
been addressed adequately by the award-winning fire safety design by Arup.<br />

Fire and life safety issues<br />
Marina Bay Sands poses particularly challenging fire and<br />
life safety issues due to the large numbers of people<br />
expected in its gaming, retail, and MICE (Meetings, Incentives,<br />
Conferences, and Exhibitions) facilities, and the prospect of<br />
having to evacuate them from multiple basement levels as<br />
well as several high-rise towers, including the Sands SkyPark<br />
and observation deck located on the 57 th storey. A key aspect<br />
of the fire safety strategy was based on minimising fire and<br />
smoke spread. A performance-based approach permitted the<br />
use of unprotected steel structure for the skypark and hotel<br />
atria, and the use of horizontal exits and monumental exit<br />
stairs for the first time in Singapore.<br />

DESIGN PROCESSES & SOLUTIONS FOR<br />
FIRE SAFETY<br />
The developer’s initial intent was for the fire safety design to<br />
be based on the requirements of the International Building<br />
Code (IBC), in line with its other properties in the region and in<br />
North America, as well as with the maintenance and operations<br />
strategies that it had developed over time.<br />
Permission was sought to adopt the IBC and, under SCDF’s<br />
instructions, a design was developed with the support of<br />
Singapore’s performance-based Fire Safety Act and Code of<br />
Practice for Fire Precautions in Buildings.<br />
The objective of the design thus became two-fold:<br />
• To design the facility according to the full requirements of the<br />
Singapore Fire Safety Act.<br />
• To address differences between the Singapore code and the<br />
IBC, by means of a combination of performance-based fire<br />
<strong>engineer</strong>ing solutions and waivers.<br />
This set in motion a design and approval process that sought<br />
to address the following key areas of the design, based upon<br />
performance-based solutions:<br />
• Evacuation of extremely large populations of people from all<br />
areas of the building.<br />
• Smoke control in all areas, and particularly the adoption of<br />
innovative methods such as natural ventilation and pressurisation.<br />
• Fire rating of structures supporting floors, walls and roofs.<br />
• The extent of fire and smoke compartmentation provided in<br />
the building.<br />
The following performance-based analyses and studies were<br />
carried out:<br />
• Comprehensive fire and evacuation modelling of all major public<br />
areas of the building, leading to a complete understanding of the<br />
performance of systems and the safe available evacuation time<br />
for people in an extremely large range of different fire scenarios.<br />
• Performance-based assessment of fire scenarios that could be a<br />
result of a potential arson situation, where a person purposely<br />
ignites a large amount of flammable liquid. Research shows that<br />
arson events caused by disgruntled employees are a credible and<br />
growing risk that buildings face.<br />
• Comprehensive blast analysis was used to inform the response of<br />
the design to various terrorist bomb blast scenarios and, where<br />
appropriate, the design was developed to include specific measures<br />
to increase its robustness to these scenarios. Marina Bay Sands is<br />
the first public building in Singapore to be designed adopting this<br />
approach, in consultation with the Ministry of Home Affairs.<br />
The following design solutions were developed in response<br />
to the unique challenges posed by Marina Bay Sands’ complex<br />
architecture.<br />
• Adoption of natural ventilation smoke control in the retail arcade<br />
in place of mechanical systems. This is a significantly more reliable<br />
method of controlling smoke spread and one that naturally<br />
regulates to larger fire sizes, unlike mechanical systems.<br />
• Integration of the hotel corridor smoke compartmentation<br />
within the atrium, to minimise its visual impact when guests at the<br />
lobby look up towards the ceiling.<br />
• Omission of ‘wicket gate’ doors in fire barriers (accordion fire<br />
doors, or similar), thereby eliminating the risk of malfunction<br />
during a fire evacuation. This was achieved through the careful<br />
selection of door types and provision of pass doors in the line of<br />
the fire wall beside the accordion fire door.<br />
• Adoption of sidewall sprinklers in appropriate areas, where an<br />
overhead sprinkler protection would be technically unfeasible.<br />
• Adoption of beam smoke detector or UV/IR systems, in place<br />
of point-type smoke detectors in high bay areas (hotel and retail<br />
atria, for example), where maintenance and servicing is difficult<br />
and potentially unsafe due to the heights involved and the need<br />
to work from mobile work platforms.<br />
It would have been extremely difficult for the project team to<br />
achieve the desired results for such a fast-track project without<br />
important contributions by various professionals.<br />
Leadership<br />
The developer led the fire safety design process in a direct<br />
and personal way. An employee at director level within the<br />
developer’s organisation was appointed to be responsible for<br />
working with the design team to ensure the development of<br />
an appropriate strategy. The influence of this role was strong<br />
and positive as it exerted influence on the design team and<br />
provided credible representation to the developer during the<br />
approval process. The individual concerned, while based in<br />
North America, held similar responsibilities for the developer’s<br />
properties in Asia, and was actively engaged and present at all<br />
meetings with the SCDF.<br />
Collaboration<br />
Collaboration within the design team and between the designers<br />
and the SCDF was notable in this project. The early stages of<br />
the design were most critical and the SCDF worked with the<br />
design team to agree on the crucial aspects of the design, as<br />

COVER STORY<br />
expressed in the project’s ‘Fire Engineering Design Brief’. This<br />
approval, in principle, enabled the design process to continue by<br />
reducing the risk of approval issues later on. This was facilitated<br />
by a process of regular meetings and presentations attended<br />
by, among others, a dedicated SCDF officer, and in which the<br />
Director of Fire Safety was also personally involved.<br />
All key meetings involving discussion of key fire safety principles<br />
were attended by the architectural and M&E (Mechanical &<br />
Electrical) Qualified Persons as well as the FSE (Fire Safety<br />
Engineer). This enabled resolution and clarification of direction,<br />
on the spot. The design team comprised two architects and<br />
two MEP (Mechanical, Electrical, Plumbing) consultants - Moshe<br />
Safdie (design architect), Aedas Singapore (project and local<br />
architect), Vanderweil Engineers (concept MEP consultant), and<br />
Parsons Brinckerhoff (project and local MEP consultant). A series<br />
of design workshops were conducted in Singapore and Boston,<br />
and regular video conferences also enabled the team to work<br />
through the fire safety concepts which were then integrated<br />
early into the architectural design.<br />
Experience<br />
The developer insisted on a team of experienced designers and<br />
contractors. A key part of this was trying to align key aspects of<br />
the design with ‘tried and tested’ solutions adopted elsewhere.<br />
The developer’s primary consultants and insurance underwriter<br />
provided this continuity. All primary consultants in the design<br />
team included team members from North America, Hong<br />
Kong and Macau, and they were included because of their prior<br />
knowledge and experience with the developer and similar fasttrack<br />
projects.<br />
SPECIAL DESIGN FOR SAFETY<br />
The following provisions were included for the safe inspection /<br />
maintenance of fire safety elements:<br />
• Assessment of fire impact on the steel structure allowed for<br />
partial fire protection of the 60 m high hotel atrium and 340<br />
m long SkyPark steel structures, thereby minimising the need<br />
to inspect and maintain the applied fire protection works.<br />
• Use of special-purpose building maintenance access<br />
incorporated into the facade structure to service the fire<br />
sprinklers and smoke vents along the grand arcade.<br />
The following provisions were specially designed to enhance<br />
and facilitate occupants’ fire safety and fire fighters’ fire fighting<br />
and rescue operations:<br />
• Entry of fire fighters into hotel Tower 1 and 3 via open stairs<br />
accessible directly from Bayfront Avenue, leading to the<br />
Basement 1 fire-fighting core.<br />
• Direct access for fire fighters from Bayfront Aveune into the<br />
Fire Command Centre (FCC) located behind the theatres.<br />
The FCC includes the following:<br />
- Manual controls to all the smoke control zones sitewide.<br />
- Status and control to all lifts sitewide.<br />
- Supervisory/controls for other fire protection equipment, eg<br />
fire pumps.<br />
• Hundred percent fire pump system back up, in addition to the<br />
Singapore requirement:<br />
-Two sets, each comprising two water tanks, are provided at<br />
Podium North Basement 3 and hotel Basement 1. Each set<br />
has a total volume of 950 m 3 , to serve the podium and the<br />
hotel up to level 23. For water supplies above level 23 of<br />
the hotel, two water tanks with total volume of 260 m 3 are<br />
provided at level 55 of Tower 1.<br />
-The underground fire service main and storage tank<br />
arrangement has been installed to comply with the Code of<br />
Practice for Fire Precautions in Buildings 2007 and FM Global<br />
Property Loss Prevention Data Sheet 3-10.<br />
-The on-site secondary water supply has been installed to comply<br />
with the Code of Practice for Fire Precautions in Buildings 2007<br />
and FM Global Property Loss Prevention Data Sheet 3-2.<br />
-One set of diesel engine-driven, vertical turbine type fire pumps<br />
and one set of electrical pumps are provided. Each set of fire<br />
pumps is minimally rated to satisfy the requirements of the Code<br />
of Practice for Fire Precautions in Buildings 2007. The electrical<br />
pumps are the main fire pumps (at Podium North B4), and the<br />
diesel pumps are a complete back-up set (at hotel B1) (ie n + n).<br />
• Provision of one evacuation lift for each of the three 55-storey<br />
hotel towers to aid escape.<br />
• All smoke control systems are designed above the minimum<br />
acceptance criteria and are based upon providing longer periods<br />
of time for people to evacuate from the building in the event<br />
of a fire. This greatly facilitates search and rescue operations by<br />
the fire brigade, as the internal environment within the building<br />
will contain less smoke and heat, thereby enabling fire fighting<br />
operations to occur in a lower- risk environment.<br />

COVER STORY<br />
INNOVATION & ENHANCEMENT<br />
The project has a high level of complex, performance-based<br />
fire <strong>engineer</strong>ing solutions applied to it. As a result, high levels of<br />
public safety are achieved. New and innovative fire safety design<br />
provisions have been incorporated in several areas.<br />
Insurance and property protection strategy<br />
The design process benefitted greatly from the involvement of<br />
the developer’s insurance underwriter from an early stage. The<br />
insurance strategy for the building was based upon the concept<br />
of ‘maximum foreseeable loss’ (MFL). This concept requires<br />
judgement to be formed about scenarios that could lead to<br />
very large amounts of fire damage to the building. Insurance<br />
premiums are based on the MFL and <strong>engineer</strong>ing measures are<br />
adopted to limit the possibility of a fire scenario resulting in a<br />
larger than assumed MFL.<br />
The key impact of this strategy upon the design was that the<br />
building was sub-divided into several large fire compartments or<br />
MFL zones. These zones included MICE, Casino, Theatres, Retail,<br />
ArtScience Museum and Hotel.<br />
All MFL zones were separated from each other by a specific firerated<br />
wall that met the insurance underwriter’s requirements<br />
and no critical services were permitted to penetrate the walls.<br />
This enabled the designers to explore an evacuation strategy<br />
that was phased in nature and involved horizontal evacuation of<br />
people from a fire-affected area into a relatively safe area not<br />
affected by fire and protected by an MFL fire separation.<br />
This is a significant departure from conventional practice,<br />
where everyone in a building would be required to evacuate<br />
simultaneously in the event of a fire alarm via exit stairs,<br />
irrespective of whether the alarm was a false one.<br />
The key advantage of the design is that the number of staircases<br />
can be reduced while still ensuring adequate means of escape,<br />
and the strategy does not lead to the entire building being<br />
evacuated in the event of detectors generating false alarms.<br />

Phased evacuation<br />
Due to its large interconnecting footprint, a horizontal exiting<br />
concept was utilised in many parts of the building where people<br />
would escape from a place exposed to the fire, heat and smoke,<br />
to a relatively safe place separated by distance and fire-rated<br />
construction. In most cases, the horizontal exit line was designed<br />
to coincide with the MFL separation required for insurance<br />
purposes to limit damage in a fire incident.<br />
While referenced widely in US-originated codes such as IBC<br />
and NFPA 101, the use of horizontal exits is uncommon in<br />
Singapore.<br />
The horizontal exits at the main entrances to the MICE and<br />
Casino also utilised another US-originated product - accordion<br />
sliding doors. Similar to horizontal sliding fire shutters, such<br />
doors are permitted under IBC to serve as part of the escape<br />
route, and are equipped to be automatically operable for people<br />
to escape and then to close. When not in use, the doors are<br />
discreetly stored in pockets recessed at the side. From a human<br />
behaviour standpoint, this design offers significant advantages<br />
since people evacuate primarily through the route that they first<br />
entered the building. Research shows that such an evacuation<br />
system results in a more efficient evacuation due to the greater<br />
familiarity that people have with the escape route.<br />
Another new concept is the use of monumental exit staircases<br />
within areas of the building that have extremely high populations.<br />
Exit staircases of up to 4 m in a scissor stair arrangement were<br />
provided for both the MICE and Casino to provide sufficient<br />
capacity for the expected 11,000 persons per floor. This differs<br />
markedly from the Code of Practice for Fire Precautions in<br />
Buildings 2007 which permits only up to 2 m of the exit stair<br />
width to be counted as capacity regardless of its width.<br />
Technical challenges included providing sufficient exits such that<br />
the failure of a single exit would not impact significantly on the<br />
overall means of escape from the space. As part of this, nonlockable<br />
doors were provided for escape at temporary partition<br />
walls within the MICE meeting rooms and ballrooms.<br />
Flexible design intent within MICE<br />
The following areas required flexibility to operate under a very<br />
large number of different configurations:<br />

• Meeting room levels: smoke and means of escape strategies<br />
to enable any combination of meeting rooms from a layout<br />
comprising 10 to eight large meeting rooms to a layout<br />
comprising 100 meeting rooms.<br />
• Grand ballroom: smoke and means of escape strategies to<br />
house the ‘largest ballroom in Asia’ on the topmost floor level<br />
of MICE. The design population for this area is in excess of<br />
11,000 people. Due to the architectural form of the roof, the<br />
opportunities for providing mechanical smoke control in this<br />
area were extremely limited.<br />
• Exhibition levels: smoke and means of escape strategies for<br />
a range of one to three exhibition halls per floor, as well as<br />
considering the impact of an exhibition being conducted<br />
in one area at the same time as an adjoining hall is being<br />
prepared for a separate exhibition.<br />
Grand arcade and view corridors<br />
In the event of a fire, smoke is vented directly outside through natural ventilation.<br />
The smoke vents are positioned at the top curve of the roof. Image by Arup.<br />
The grand arcade and view corridors are the only three zones<br />
that make up the Marina Bay Sands shops. Uninterrupted by<br />
smoke curtains, each of the retail smoke zones is formed by<br />
the curves and bends of the geometric design of the five-storey<br />
atrium design space. Smoke is vented directly outside through<br />
natural ventilators, in the event of a fire.<br />
Technical challenges associated with the design of the natural<br />
ventilation systems included determining the best location to<br />
place the smoke vents (at the top curve of the roof), to limit its<br />
visual impact to visitors on the 4 th storey roof terraces, without<br />
compromising the efficiency of the vents during a fire. The<br />
smoke hazard management strategy was based upon extensive<br />
Computational Fluid Dynamics (CFD) smoke modelling of the<br />
building with and without wind effects. Large combinations of<br />
fire sizes and location were considered, to assess the impact of<br />
reduced buoyancy of smoke, along with assessment of whether<br />
the design was appropriate for prevailing wind conditions.<br />
Expert advice from wind <strong>engineer</strong>s and wind tunnel analysis<br />
was received.<br />
The net result highlights the opportunity that performancebased<br />
fire <strong>engineer</strong>ing offers designers. The strategy is based<br />
entirely on natural ventilation and smoke zoning formed by the<br />
geometric design of the building.<br />
Crystal pavilions<br />
The crystal pavilions appear to float on Marina Bay, when they<br />
are actually connected by a sub-marine link to the retail part of<br />
the development.<br />
A key constraint of the early design was that the architect did<br />
not want a visible connection between the pavilions and the<br />
building. Therefore, the only escape route would be via the submarine<br />
link.<br />
From a fire safety point of view, a single means of escape was<br />
unacceptable and alternative designs were brainstormed and<br />
considered at length. Amongst the design options considered<br />
were the use of rescue boats, floating decks and submerged<br />
egress tunnels back into the podium. The final design allows<br />
alternative exiting from the pavilions at water level to the<br />
promenade.<br />
Hotel towers<br />
The smoke control strategy for the hotels was a critical aspect<br />
of the design. The three hotel towers all share a common atrium.<br />
From each hotel guestroom, there is an open path between the<br />
hotel corridor/internal balcony and the atrium. Therefore, if a<br />
fire was to occur in one of the food and beverage outlets in the<br />
base of the atrium, smoke could spread to the internal balconies<br />
and impact the evacuation of hotel guests.<br />
The performance-based solution adopted for the hotel atria<br />
develops a smoke control strategy from first principles. The<br />
design protects both evacuating hotel guests and people at the<br />
base of the atrium. It does this, primarily, through the provision<br />
of smoke curtains to prevent smoke spread onto the internal<br />
corridors of the hotel, creation of a positive pressure field on<br />
the internal corridor and then provision of mechanical smoke<br />
extract at the top of the atrium. Make-up air is provided for the<br />
smoke extract system by opening doors to the outside.<br />
The net result is an extremely simple and effective method of<br />
controlling smoke while enabling large amounts of flexibility<br />
to the type of activities that can be carried out in the hotel<br />
lobby.<br />
The three hotel towers are linked at ground level by<br />
triangular glass and steel structures up to 23 storeys high.<br />
The elegant steel trusses carrying the vertical loads are fireprotected<br />
up to 10 m above ground level. Beyond this point,<br />
the structures are unprotected. This solution was possible by<br />
studying a range of different fire scenarios and their impact<br />
on the ability of the structure to resist loads in the event of<br />
fire. It was found that above a critical height, the impact of<br />
fire was negligible and it was safe for the structure to remain<br />
without fire protection.<br />

the designated exits, identifying areas of potential bottleneck<br />

essential to communicating the basis of the exiting design to the<br />
developer and their operations team. It is also intended to be a<br />
one-stop point of reference for assessing the impact of possible<br />
changes to the building, and its use in the future.<br />
Secondly, the entire fire safety design, including the prescriptive<br />
and performance-based requirements, was documented in a<br />
single report. This report presented the overall strategy for the<br />
integration of fire safety systems, along with management and<br />
operational requirements.<br />
Hotel atrium steel structural analysis. Image by Arup.<br />
Sands SkyPark<br />
Where the hotel skypark spans between each tower and<br />
cantilevers beyond Tower 3, the huge structural steel members<br />
are without applied fire protection, though this would be a<br />
requirement under a prescriptive design. Using a performancebased<br />
approach, it was determined that any structure outside<br />
an immediate zone around a possible worst-credible fire within<br />
the towers could remain unprotected and yet still maintain its<br />
stability in a fire.<br />
A performance-based approach was also applied to the skypark<br />
evacuation. With a possible population of up to 3,900 persons<br />
within level 56 and 57, the overall evacuation strategy is to<br />
evacuate people from the skypark deck to floors below and<br />
horizontally from the shadow of one tower to another. This<br />
solution provides maximum flexibility to the developer in the<br />
different types of events that they may wish to hold on the<br />
skypark levels.<br />
QUALITY DOCUMENTATION<br />
The developer insisted that Arup provide three different types<br />
of documentation that are not typically prepared for projects<br />
in Singapore.<br />
Firstly, as part of the fire safety documentation, means of<br />
escape drawings were produced to enhance understanding<br />
of the overall escape provisions from each component of<br />
the development. These drawings are, in essence, a graphical<br />
representation of populations and flow of people in the building<br />
in an emergency, through the available escape routes and onto<br />
Finally, the entire smoke control design for all areas of the<br />
building was documented, for the purposes of the design team<br />
and developer, adopting a North American approach. These<br />
drawings presented the entire set of requirements associated<br />
with the smoke control systems, including any and all interfaces<br />
with other systems and trade packages. The intention is that<br />
existence of these drawings prevents the loss of essential design<br />
requirements, especially when the full extent of the requirements<br />
of an entire smoke control system is actually expressed on a<br />
number of different documents.<br />
FIRE-FIGHTING OPERATIONS<br />
As part of the phased TOP (Temporary Occupation Permit)<br />
process, arrangements were made by Marina Bay Sands to<br />
have the FSSD (Fire Safety and Shelter Department) inspect<br />
and familiarise itself with the many fire and life safety provisions<br />
made in the development, including vehicle access around<br />
the site. CCTV coverage is also duplicated (from the security<br />
surveillance) to permit observance of evacuation lobby areas in<br />
the hotel towers. Zoning information (smoke zones, fire alarms)<br />
as well as the lift status (normal, fire) are provided in the FCC<br />
for ease of coordination of fire fighting operations.<br />

of the misconceptions and<br />

INTRODUCTION<br />
Earthing-grounding is an important element for the safe<br />
operation of an electrical power system. The basic principles of<br />
grounding have been developed and refined from an early artrules<br />
based practice to the science based practice of to-day.<br />
There are three schools of thought with regard to ground-rod<br />
length. The first approach states that extending the ground-rod<br />
length beyond 3 m is of little value for most types of soil. The reason<br />
is that beyond 3 m length, a point of diminishing returns is reached.<br />
The second school of thought concludes that the optimum earthto-rod<br />
interface is achieved with longer (12 m or more) rods, driven<br />
to penetrate the ground until it reaches the water table.<br />
The third school of thought concludes that the optimum groundrod<br />
installation is achieved by using the longest possible rod length.<br />
Given these three conflicting approaches, it is no wonder that<br />
the current practice of relying on the use of conventional<br />
ground-rods as earthing-grounding electrodes, may be far from<br />
satisfactory, in terms of the performance and fulfillment of their<br />
designed function in the electrical power system for present day<br />
commercial and industrial buildings, where sensitive electronic<br />
equipment and computers etc are installed and used. Hence,<br />
a review of the current earthing-grounding practice is not only<br />
necessary but also timely.<br />
EARTHING-GROUNDING<br />
Examining the reasons and the requirements for earthinggrounding,<br />
IEEE and IET both define grounding as a conducting<br />
connection, whether intentional or accidental, by which an<br />
electric circuit or equipment is connected to the earth or to<br />
some conducting body of relatively large extent, that serves<br />
in place of the earth. Its purpose is to establish and maintain<br />
the potential of the earth at near zero or approximately that<br />
potential on the conductor connected to it, and for conducting<br />
of ground current to and from the earth.<br />
Key components<br />
Any earthing-grounding system must consist of two key<br />
components - the earth-to-ground electrode interface outside<br />
the building/facility, and an AC power and signal-wiring system<br />
inside the building/facility.<br />
Specific purposes<br />
Earthing-grounding schemes can be simple or complex, but any<br />
scheme chosen must serve the following purposes:<br />
• Electrical system and winding earthing-grounding.<br />
• Equipment and enclosure earthing-grounding.<br />
• Provide safety protection to operators.<br />
• Provide protection to electronic equipment from damage<br />
caused by transient disturbances.<br />
• Divert stray radio-frequency energy away from sensitive<br />
electronic equipment.<br />
Justification for a well-designed system<br />
The 400 V or 230 V 50 Hz AC line current that powers most<br />
commercial and industrial equipment can be dangerous or even<br />
deadly, if not handled properly. Therefore, the attention given<br />
to its proper design and installation, including provision of an<br />
effective earthing-grounding system, is key to the safe operation<br />
and day-to-day reliability of any electrical power system. But a<br />
well designed and installed earthing-grounding is often invisible,<br />
and when everything goes well, it is forgotten or even neglected.<br />
On the other hand, a marginally designed and installed earthinggrounding<br />
system is most likely to cause problems on a regular<br />
basis, often with unpredictable consequences.<br />
Effective earthing-grounding of equipment enclosures and<br />
structures provides protection against wiring errors or faults<br />
that could endanger human life. Too often, these facts are not<br />
well recognised and sometimes inadequate attention is given<br />
to details in the design and installation of a facility’s earthinggrounding<br />
system,<br />
Earth-grounding of electrical systems and equipment<br />
enclosures<br />
There are only two reasons why electrical systems and<br />
equipment enclosures are connected to earth-ground. The first<br />
reason is for system earthing-grounding, where the intentional<br />
earthing performs a continuous and intended function during<br />
normal operation of an electrical system. The second reason<br />
is to install and provide an earthing-grounding system, which<br />
only comes into effect if an accidental or unintentional voltage<br />
is applied to a non-current carrying part of the equipment,<br />
for the safety and protection of operators. It is for these very<br />
reasons that the electrical code CP5 dealt with this particular<br />
aspect of safety and other requirements for effective earthinggrounding<br />
in such great detail. Hence, all electrical workers<br />
who are responsible for the design, installation, operation and<br />
maintenance of electrical power systems must have a thorough<br />
understanding of and be familiar with the requirements of the<br />
electrical code.<br />
Electrical circuit earthing-grounding<br />
Essentially, electrical circuits are grounded to limit the maximum<br />
potential difference to earth due to the normal voltage for which<br />
the circuit is designed. The concern is with the magnitude of the<br />
potential difference which could be accidentally applied to a person,<br />
as this could mean the difference between life and death.<br />
20 THE SINGAPORE ENGINEER May 2012
ELECTRICAL ENGINEERING<br />
Safety requires not only the right equipment but also its proper<br />
installation and effective earthing. If we consider an average<br />
individual with, say, 820 ohms body resistance, we can see<br />
that an increase in voltage will give rise to increased current.<br />
Experimental studies have established that a current of around<br />
150 Ma would be considered as dangerous fibrillation current.<br />
However, time is also a critical factor. For 150 Ma, beyond 1<br />
sec duration, it must be considered as very dangerous. With<br />
reference to cardiac arrest, previous studies have shown that<br />
loss of muscle control, that is, the inability to let go a 50Hz<br />
current-carrying conductor occurs at around 10-15 Ma with<br />
stoppage of breathing occurring at around 20 Ma. From this<br />
observation, it can be concluded that any small flow of current<br />
through a person can be dangerous. It is this information and<br />
observation that creates the background and places the design<br />
of earthing-grounding systems in a proper perspective.<br />
Ground-rod electrode and earth resistance<br />
In practice, all voltage measurements are made with the earth<br />
as the reference, which is always assumed to be maintained at<br />
absolute zero potential, but this is not truly correct. The only<br />
truly absolute zero potential spot on earth is at the centre of<br />
the earth, which is remote and inaccessible from the surface<br />
of the earth. So, any other location inside the earth will have<br />
a non-zero potential. Therefore, any object such as earthing<br />
rods, buried hemispheres, buried bare copper wire conductors,<br />
copper plates, building foundations and steel structures on the<br />
surface of the earth will likewise have non-zero potential.<br />
Objects like ground rods and hemispheres, which are in contact<br />
with the soil, will have a potential higher than zero. Hence, the<br />
potential difference ‘V’, between the object, like the ground rods<br />
or hemispheres, and the centre of the earth, can be represented<br />
by Ohm’s law V= IR, where ‘I’ is the current flowing from the<br />
object like the ground rod or hemisphere to the centre of<br />
the earth, and ‘R’ is the resistance between the object like the<br />
ground rod and or hemisphere and the centre of the earth. This<br />
resistance ‘R’ is called the earth resistance.<br />
The exact computation of the earth resistance of an object-like<br />
the ground rod or hemisphere is a very tedious task and requires<br />
the knowledge of highly varying parameters, some of which<br />
are often non-linear and are hard to measure. Nevertheless, a<br />
simplified computation of the earth resistance of an object, like a<br />
ground-rod or hemisphere can be made with a reasonable and<br />
fair degree of accuracy for practical use.<br />
Taking the case of a copper hemisphere, buried 1 m deep in<br />
homogeneous soil with a soil resistivity of ‘ρ’ ohm-metre, if the<br />
hemisphere is connected to a conductor that carrys a current<br />
‘I’, the current enters the hemisphere and is then distributed<br />
uniformly through the earth. The current density at the surface<br />
of the hemisphere ‘J’, is the current leaving the hemisphere<br />
divided by the surface area of hemisphere:<br />
I<br />
J =<br />
where r = radius of the hemisphere<br />
2π r 2<br />
Since the soil is homogenous, the current density at any point ‘x’<br />
from the centre of the hemisphere, and outside the hemisphere,<br />
can be computed as:<br />
I<br />
J (x) =<br />
where x ≽ r<br />
2π x 2<br />
Ohm’s law states that the current flowing in a medium also<br />
creates an electric field intensity ‘E’ that is equal to the current<br />
density ‘J’ multiplied by the soil resistivity (ρ). Hence, the electric<br />
field intensity ‘E(x)’ at any distance ‘x’ outside the hemisphere is:<br />
E(x) = ρ.J(x)<br />
where x ≽ r<br />
For homogeneous soil, the potentials of all points located at the<br />
same distance from the centre of the hemisphere are all equal,<br />
hence the potential difference between any two points ‘a’ and<br />
‘b’ inside the earth can be computed by integrating the electric<br />
field intensity between these two points. Hence:<br />
X=b X=b ρ.I 1 1<br />
V ab = ∫ x=a E(x)dx = ∫ x=a ρ.J (x)dx =<br />

It follows that to compute the earth resistance of the<br />
hemisphere, having a radius of ‘r’, making r a = r and r b = ∞<br />
Therefore, the earth resistance of the hemisphere, Rg, can be<br />
computed as follows:<br />
ρ<br />
R g = ohms<br />
2πr<br />
Now taking this copper hemisphere, 2 m in diameter, buried<br />
1 m deep in a wet organic soil as an electrode, with ρ = 10<br />
Ω-metre, to its obvious conclusion, it is possible to compute:<br />
1) The earth resistance of the hemisphere.<br />
2) The earth resistance at 2 m, 10 m, and 100 m from the<br />
centre of the hemisphere.<br />

The 2.2 rule for location and placing of electrodes<br />
From these computation results, it can be concluded that the<br />
change in earth resistance is insignificant when the distance<br />
from the centre of the hemisphere increases beyond 10 m.<br />
So practically, the earth resistance of an object, in this case,<br />
a hemisphere, is a function of the immediate distance rather<br />
than the distance to the centre of the earth. Hence, the basic<br />
measure of the effectiveness of an earth electrode resistance<br />
is the immediate distance from the centre of the hemisphere<br />
and not the distance to the centre of the earth.<br />
In short, it is the resistance between the point of connection<br />
to the hemisphere earth electrode and a distance point of<br />
about 2.2 times the depth of the hemisphere or the length of<br />
the ground rod as the case may be. This is known as the 2.2<br />
rule for the installation and location of earth electrodes to<br />
achieve adequate low values of earth resistance for effective<br />
earthing-grounding of an electrical power system.<br />
However, providing and installing an effective earthinggrounding<br />
system to achieve a good ground-electrode<br />
interface is only half the battle for a system/facility planner<br />
or designer. The second, but equally important element<br />
of any effective earthing-grounding system is the layout<br />
or configuration of earthing-grounding conductors inside<br />
the building, particularly those for data centres, computers<br />
and other sensitive electronic equipment usually found in<br />
commercial and industrial buildings/facilities.<br />
There are many different methods that can be used to<br />
implement and achieve an effective earthing-grounding<br />
system, but some conventions should always be followed to<br />
ensure a low resistance and low inductance layout that will<br />
perform as required. Proper and effective earthing-grounding<br />
is important in present day commercial and industrial<br />
buildings/facilities, whether or not the building/facility is<br />
located in a high radio frequency field area or location.<br />
So, given the importance of effective earthing-grounding<br />
in today’s facilities, and the conflicting approaches to the<br />
selection and adoption of proper earth electrode systems,<br />
the benefits of hiring an experienced, licensed professional<br />
electrical <strong>engineer</strong>, to plan and design a proper and effective<br />
earthing-grounding system for a facility or plant installation,<br />
can be readily appreciated.<br />
Calculating the earth resistance<br />
Although an equation has been developed to calculate the<br />
earth resistance of an hemisphere electrode, it can only be<br />
taken as an approximation for practical purposes. Other<br />
equations have also been similarly developed for various<br />
systems of electrodes, and in all cases, are also approximations.<br />
The exact formulation of equations is quite complicated.<br />
All equations are derived from the general relation, R = PL /<br />
A, and are based on the assumption of uniform soil resistivity,<br />
although this is seldom the case in the real world.<br />
Now assuming that a ground rod, 4 cm diameter, is used<br />
instead of the hemisphere electrode mentioned above, and<br />
is driven 1 m into the ground with the same soil resistivity as<br />
in the case considered earlier.<br />
The earth resistance of the ground rod is computed as:<br />
R g rod =<br />
ρ<br />
2πL<br />
log<br />
ρ<br />
= log<br />
2π x 1<br />
= 7.345 ohms<br />
2 L + r<br />
r<br />
2 + 0.02<br />
0.02<br />
Comparing this value of 7.345 ohms with that of the<br />
hemisphere electrode (1.6 ohms), it is very much higher. This<br />
means that using the ground rod as the grounding-earthing<br />
electrode is very much less effective than the hemisphere,<br />
and more ground rods would be needed to achieve the<br />
same low value of earth resistance as derived from using the<br />
hemisphere electrode.<br />
The following equations have been developed and used to<br />
calculate the earth resistance of some common objects used<br />
as earth electrodes:<br />

Ground resistance of people<br />
A person standing on the ground and a person walking on the<br />
ground have different ground resistance. A person standing<br />
on the ground normally has his/her feet close enough to<br />
each other, whilst a person who is walking or running would<br />
normally have his/her front and rear feet far apart.<br />
For a person who is standing, each foot has a ground<br />
resistance R f between the bottom of the foot and the centre<br />
of the earth. Using a circular plate that has the same area as<br />
the footprint of an average person, as a model, the ground<br />
resistance equation for the circular plate can be used to<br />
calculate a person’s single foot ground resistance R f , which is<br />
ρ<br />
R f rod = ohms.<br />
4r<br />
Now, the commonly accepted<br />
area of an average person’s single<br />
footprint is about 0.02 m 2 and the<br />
area of a circular plate is A = π r 2 ,<br />
where ‘r’ is the radius. Therefore,<br />
A single foot ground resistance is R fg =<br />
4r<br />
Ground resistance for a standing person is R o = 0.5R f = 1.5ρ<br />
The total ground resistance of a<br />
person who is walking or running,<br />
and of a person who is standing,<br />
are:<br />
R f standing = 0.5R f<br />
= 1.5ρ ohms<br />
R f walking = 2 R f ohms<br />
Ground resistance for a person who is walking,<br />
is R g = 2R f = 6ρ<br />

Body resistance<br />
The body resistance of human beings is highly non-linear<br />
and is a function of several factors such as the hydration<br />
condition of the body, skin condition, and fat concentration.<br />
The IEEE had established the ranges for various body<br />
resistance values.<br />

Electric shock<br />
Electric shocks occur when people become part of a<br />
functional and active electrical circuit and according to<br />
Ohm’s law, a current will flow through the body. The degree<br />
of injury depends on several factors, such as the duration of<br />
the shock, types of shock and the pathway of the current and<br />
its frequency.<br />
Electric shocks are generally classified into two categories -<br />
the secondary shock and the primary shock. The secondary<br />
shock is due to low current that may cause pain without<br />
physical harm. The primary shock, however, is due to a higher<br />
current that produces direct physical harm and/or death.<br />
The question is then how to find out the safe limit of the<br />
electrical current passing through the body. It is hard to find<br />
human volunteers for primary shock experiments. Early<br />
researchers, however, did their secondary shock studies on<br />
humans and primary shock studies on animals with similar<br />
weight and biological characteristics as human beings.<br />
Among the many highly respected researchers who did<br />
research work in this area was Charles Dalziel of the US. In<br />
one of his papers published in 1972, he summaries the results<br />
of his findings which until to-day are being used as the defacto<br />
limits. They were adopted in 1993 as the IEEE Standard<br />
524a for secondary shock current limits.<br />

Charles Dalziel also carried out research on the time-current<br />
relationship for primary shock on animals with weight and<br />
organ sizes similar to that of humans. Based on these studies,<br />
he developed the following current duration formula for<br />
ventricular fibrillation:<br />
K<br />
I =<br />
1/2<br />
t<br />
Where ‘I’ is the ventricular fibrillation current in milliamps<br />
‘t’ is the time duration of the current in seconds<br />
‘k’ is a constant value that depends on the weight of the<br />
test object<br />
Note: For people less than 70 kg, k= 116. For people more than<br />
70 kg, k = 157.<br />
Charles Dalziel’s experimental studies concluded that the longer<br />
the duration of the shock, the higher is the likelihood of death. If<br />
the current interferes with the operation of the heart or lungs,<br />
the higher is the chance of death. Also, when the current is<br />
above the let-go threshold, people are incapable of releasing<br />
their grip on the wire and the shock duration is often long.<br />
Now considering a scenario where a 400V, 3 phase, 50 Hz main<br />
switchboard operates in a humid and dusty environment, and<br />
the surface of a bus bar insulator became contaminated with<br />
dampness and dust. These mix conditions and environment<br />
caused the insulator to fail partially and allowed a 10 Amp<br />
current to pass through the switchboard structure to the<br />
ground. Assuming that the switchboard is grounded through<br />
a hemisphere electrode with a radius of 0.5 m, and the soil<br />
surrounding the hemisphere is moist with soil resistivity ρ =<br />
100 ohm-metre, under this scenario, if an electrical worker with<br />
a body resistance of 3000 ohms touches the metal frame of<br />
the main switchboard while standing on the ground within the<br />
switchroom, what magnitude of current would pass through the<br />
electrical worker and for how long can he/she take the shock?<br />
Calculations<br />
1) First, computing the ground resistance of the hemisphere:<br />
ρ 100<br />
R g (hemisphere) = = = 32 ohm<br />
2πr 2π x 0.5<br />
2) The voltage of the main switchboard is the ground potential rise:<br />
V = I R g (hemisphere) = 10 x 32 = 320 V<br />
3) To compute the current through the electrical worker, it is<br />
necessary to determine first Rf with he/she standing on<br />
the ground.<br />
R f = 3ρ = 3 x 100 = 300 ohms<br />
The current through the electrical worker’s body would be:<br />
I . R g<br />

can survive for:<br />

Now considering a grounding rod, 4 cm in diameter, driven 1 m<br />
into the ground, is used instead of the hemisphere, it is possible to<br />
determine the effect and impact on the electrical worker:<br />

2) Voltage of the main switchboard due to ground potential rise is:<br />
V = I R g (rod) = 10 x 73.45 = 734.5 V<br />
3) The current passing through the electrical worker is:<br />
I . R g<br />
I(Worker) =<br />
R g + R Worker + 0.5 R f<br />
10 . 73.45<br />

From these calculations, it can be concluded that the grounding<br />
rod provides less protection than the hemisphere and there is<br />
a high chance that the electrical worker will not survive under<br />
these circumstances.<br />
Next, considering another scenario - a short circuit current<br />
of 1000 A passes through a hemisphere ground. A person is<br />
walking 5 m away from the centre of the hemisphere. Assuming<br />
that the leg to leg body resistance of the person is 2000 ohms<br />
and the soil surrounding the hemisphere is moist, the magnitude<br />
of the current through the person and his step potential with a<br />
step distance of 0.6 m, can be determined.<br />
Calculations<br />

Since R f = 3ρ = 300 ohms<br />

It should again be noted that the ground rod provides less<br />
protection than the ground hemisphere. But in this case, the<br />
current is passing through his/her legs and not through his/her<br />
body, he/she may survive this severe shock. However, if he/she<br />
falls then there is a high possibility that the current will flow<br />
through his/her body, then death is a certainty.<br />
Neutral versus ground<br />
One of the most confusing issues in electrical safety is the<br />
difference between the neutral and the ground terminals. They<br />
are both grounded, so why do we sometimes use both of them?<br />
To answer this question, one needs to go back to the basics<br />
and examine the constructional and functional features of the<br />
internal electric circuit of the equipment, which is usually housed<br />
inside a metallic chassis. As always, this internal electric circuit is<br />
electrically isolated from the metallic chassis.<br />
On examination of these constructional features, we know from<br />
basic principles that a difference of potentials would always<br />
exist between two adjacent conductive elements due to the<br />
presence of parasitic capacitance between them. The existence<br />
of this capacitive coupling, between the internal electric circuit<br />
and the metallic chassis, causes the elevation of the potential<br />
of the chassis. The current of the internal electric circuit would<br />
likewise produce magnetic fields that link the chassis and would<br />
induce an elevated voltage on the chassis. Last, but not least, if<br />
there is any fault inside the internal electric circuit, this could<br />
also result in the chassis touching the internal electric circuit<br />
components at elevated voltage.<br />
Potential of chassis elevated through parasitic capacitance and<br />
magnetic field of internal electric circuit or through a fault.<br />
Now, if the ground rod is used instead of the hemisphere, the<br />
open circuit step voltage across the person’s leg is:<br />

Now, if a person standing on the ground touches the chassis,<br />
that person would form part of the closed electrical circuit and<br />
a current would flow through the leakage capacitance, his/her<br />
body resistance, and finally to the ground. The magnitude of this<br />
current could be very small and the person may just feel it with a<br />
skin sensation or nothing. However, if the internal electric circuit<br />
is faulty, the current could reach an unsafe level. To protect that<br />
person from this form of hazard, the neutral of some equipment<br />
is sometimes connected to the chassis (TN-C-S System). In this<br />
way, the chassis is held at the potential of the neutral wire and<br />
no current flows through the person.<br />

ELECTRICAL ENGINEERING<br />
When a person standing on the ground touches the chassis,<br />
that person would form part of the closed electrical circuit. A<br />
current would flow through the leakage capacitance to his/her<br />
body and finally to the ground.<br />
In another example, assuming the electrical equipment is powered<br />
by a 230V single phase supply and the resistances of phase and<br />
neutral conductors are each 0.5 ohm, and assuming that the<br />
resistance of the man plus the ground resistance is 1500 ohms, if<br />
the equipment draws 20 Amp and the man standing on the ground<br />
touches the chassis of the equipment, the magnitude of the current<br />
flows through the man would be calculated as follows:<br />
I man = 20 . 0.5<br />
= 6.7 Ma<br />
0.5 + 1500<br />
To protect that person from this form of hazard, the neutral is<br />
connected to the chassis (for some equipment). In this way, the I man = 50 . 0.5<br />
= 16.75 Ma<br />
chassis is held at the potential of the neutral wire and no current<br />
0.5 + 1500<br />
flows through the person.<br />
But, this practice is not always safe, particularly when the wires<br />
that supply the electrical power to the equipment are long and<br />
far from the source or distribution panel. The current from the<br />
source is now able to return to the ground through two paths<br />
- one through the neutral wire ( I N ) and the other through the<br />
person ( I man ).<br />
The magnitude is calculated as I man :<br />
I.R N<br />
I man =<br />
R N + R man<br />
Where R N is the resistance of the neutral wire<br />
R man is the resistance of man plus the ground resistance<br />
I is the current flowing from the source to the electrical equipment<br />
If however, the electrical equipment develops an internal fault<br />
and draws 50 Amp from the line supply without tripping the<br />
circuit breaker, the current flows through the man can be<br />
calculated as follows:<br />
These examples shows that the neutral wire may not provide<br />
the man adequate protection from electric shock. To correct and<br />
overcome this problem, the chassis must be connected directly<br />
to the local ground-earth. The local ground-earth is established<br />
by driving a separate ground rod or hemisphere electrodes into<br />
the local ground close to the facility independent of the utility<br />
transformer Neutral grounding-earthing electrodes. In this way, the<br />
current can have two paths to flow, one through the neutral wire<br />
(I N ) and the other through the local ground (I G ). The resistance<br />
of the man is usually very much higher than the local ground and<br />
almost no current flows through his body. This is the main reason<br />
why in Singapore, this method of earthing-grounding system for all<br />
non-current carrying conductors and enclosures, has been chosen<br />
as the preferred earthing-grounding system for protection against<br />
electric shocks. This form of earthing-grounding is commonly<br />
known as the ‘TT’ system.<br />
26 THE SINGAPORE ENGINEER May 2012
ELECTRICAL ENGINEERING<br />
In ‘TT’ system earthing-grounding, the transformer neutral is<br />
connected to grounding-earthing electrodes normally at the<br />
transformer station, and the chassis or enclosures (non-current<br />
carrying conductive parts) of the electric equipment are<br />
connected to the local earthing electrodes. In case of a short<br />
circuit between the phase conductor and chassis or enclosure,<br />
the resistance of the earthing electrodes will limit the short<br />
circuit current, but dangerous voltage can still rise between the<br />
enclosures and earth. For this reason, residual current protection<br />
with instantaneous operation is required to ensure adequate<br />
protection against electric shock.<br />
CONCLUSION / REMARKS<br />
• An earthing-grounding system selection and design starts<br />
with site analysis and collection of soil resistivity data of the<br />
area, once the need is established.<br />
It is strongly recommended that prior to selecting the type of<br />
electrodes to be used, soil resistivity tests of the site be carried<br />
out to confirm the actual soil resistivity values.<br />
• One of the key factors in any electrical protection scheme<br />
is achieving effective low ground resistance. If any acceptable<br />
measure of safety is to be attained, correct earthing-grounding<br />
design and application must be strictly followed.<br />
• An effective earthing-grounding system must satisfy the<br />
following conditions:<br />
a) It should provide a low resistance path to ground for<br />
personnel and equipment protection.<br />
b) It should be relatively corrosion-free and able to<br />
withstand large surge currents.<br />
c) It must be able to provide adequate protection to all sensitive<br />
electronic or computer equipment to ensure their proper<br />
operation and ensure the safety of operating personnel,<br />
by effective earthing of power frequency equipment in<br />
accordance with CP5 and the use of signal reference grid<br />
(SRG) forms of earthing for higher frequency equipment,<br />
such as sensitive electronic equipment and computers.<br />
• The question always asked is “How low should the earth<br />
resistance be?”. It is difficult to determine this in ohms. But<br />
from field experiences, the lower the resistance value, the<br />
more effective and safer is the earthing-grounding system.<br />
For personnel and equipment protection, it is worth the<br />
effort to aim for a ground resistance of less than 1 ohm.<br />
However, in exceptional circumstances a high value of > 5<br />
ohms may be allowed.<br />
• The current practice of relying on the use of conventional<br />
ground rods as earthing electrode provides far less effective<br />
earth resistance as compared with the hemisphere electrode,<br />
as demonstrated by calculations in the examples included in<br />
the article.<br />
• Since, it is now established that ground rods are less effective<br />
as earth electrodes, should the electrical <strong>engineer</strong>ing<br />
profession initiate a call for change?<br />

New industrial power supplies with lower<br />
energy consumption<br />
Small and energy-efficient products help to reduce carbon emissions.<br />
In the search for potential savings to be realised by industries,<br />
the cost of energy is becoming an increasingly important factor.<br />
Plant operators are forced to scrutinise the energy consumption,<br />
not only due to cost pressures, but also legal requirements for<br />
protecting the environment call for that. Besides the typical<br />
energy guzzlers, the ‘little ones’ such as low-wattage power<br />
supplies, must not be overlooked. With energy-efficient switching<br />
power supplies, considerable savings are still possible here.<br />
Global climate change is one of humanity’s greatest challenges.<br />
With the signing of the Kyoto Protocol, leading industrialised<br />
countries agreed to reduce their collective annual greenhouse<br />
gas emissions by an average of 5.2% from the levels of 1990<br />
over the time period between 2008 and 2012. This brought<br />
about a decisive turnaround in the way we deal with energy<br />
and raw materials.<br />
Siemens is said to be the world’s largest supplier of environmentfriendly<br />
technology. By utilising products and solutions from its<br />
environmental portfolio, Siemens’ customers have reduced<br />
carbon dioxide emissions by 210 million tons in the same time<br />
period, which equals the combined amount produced by the<br />
cities of New York, Tokyo, London and Berlin. The environmental<br />
portfolio of Siemens also includes SITOP regulated industrial<br />
power supplies which have operated reliably in a wide range<br />
of applications relating to production, process, and building<br />
automation, for over 15 years.<br />
Energy efficiency as competitive advantage<br />
Aside from the careful treatment of the environment and<br />
resources, it is, above all, the ever-growing cost pressure<br />
that forces industrial companies to examine their energy<br />
consumption. Especially in the production environment,<br />
the efficient use of energy has long ago become a decisive<br />
competitive factor. This affects the large electricity consumers,<br />
eg electric drives of primary and ancillary systems, as well as the<br />
power supplies responsible for providing electricity - and here,<br />
not only the large ones, but also those that transfer relatively<br />
little to very little power.<br />
For some time now, industries have primarily been using<br />
switching power supplies for supplying electricity, which<br />
are inherently energy-efficient and possess a much higher<br />
efficiency compared to conventional linear power supplies. As<br />
a leading supplier of industrial power supplies, Siemens offers<br />
a functionally tiered product range of switching power supplies<br />
which are characterised by their reliability, compactness and<br />
energy efficiency. However, significant savings can still be had<br />
here - as Siemens is demonstrating with the development of the<br />
new product line, SITOP compact.<br />
Low losses throughout the relevant load range<br />
Power supplies for industrial applications or building services<br />
continue to be designed in such a way that they offer the<br />
highest possible efficiency at maximum load, eg when turning<br />
on capacitive electricity consumers. Simply stating the efficiency<br />
at nominal load is not an indicator for an efficient power supply.<br />
This is because power supplies are normally run in a load range<br />
between 30% and 70% of the nominal or maximum output,<br />
depending on the process, eg the switching of motors, actuators<br />
or sensors. In addition, there are production-free or idle times<br />
when individual electricity consumers or plant sections are<br />
switched into a ‘standby mode’ to save energy. This requires the<br />
power supply to minimise the energy consumption during noload<br />
times.<br />
As a result, several requirements were addressed during the<br />
development of the new SITOP regulated power supplies<br />
product line.<br />
In particular, the power supplies should:<br />
• have a high efficiency over the entire load range and therefore<br />
low power dissipation.<br />
• be designed for input voltages between 85 V AC and 265 V<br />
AC (wide-range) so that they function on 1-phase 120 V AC<br />
and 230 V AC power networks without switching.<br />
• also be operational on DC power networks with 110 V DC to<br />
300 V DC<br />
• have minimum no-load losses.<br />
As a technical approach, the quasi-resonant operation of a flyback<br />
converter was chosen. In particular, for the wide-range input<br />
with power ratings up to 100 W, this promises an optimal priceperformance<br />
ratio. Furthermore, the power dissipation is greatly<br />
reduced, since the switching losses are exceptionally low. In the<br />
case of a quasi-resonant converter, the actual ‘parasitic network’<br />
of transformer and power semiconductor is exploited. By means<br />
of an energetically optimal activation of the semiconductor, it<br />
is restarted at a time when the switching voltage reaches a<br />
minimum, ie significant load shedding is present. Characteristically,<br />
in doing so, the energy storage devices involved in the resonance<br />
mutually exchange their energy, and not convert it into heat in a<br />
resistor. Another benefit of the quasi-resonant topology is that<br />
the electromagnetic interference (EMI) is considerably lower<br />
than in applications with direct switching.<br />
Low losses also during no-load<br />
To keep the no-load losses to a minimum, a control IC specifically<br />
developed for this was integrated into the switching electronics<br />
of the power supply. The IC itself is designed to consume only<br />
a fraction of the power compared to earlier components. The<br />
entire switching electronics is thus considerably more energyefficient.<br />
With it, the SITOP compact power supplies meet the<br />
requirements concerning standby losses which cannot exceed<br />
1 W as defined in the ‘Eco-Design Directive’ 2009/125/EC for<br />
28 THE SINGAPORE ENGINEER May 2012
SUSTAINABILITY<br />
household and office appliances. The objective of this directive<br />
for energy-using products (EuPs) is to improve their energy<br />
efficiency, thus supporting the realisation of the European<br />
climate protection goals.<br />
Another challenge was the adherence to industrial requirements<br />
concerning the output voltage regulation at partial to no load.<br />
Unlike in the consumer sector, it is not specified from the outset<br />
as to which electricity consumers are to be supplied with electric<br />
power by the industrial power supply. This means that it is also<br />
not clear what kind of voltage fluctuations can be tolerated by<br />
the individual electricity consumers. In the consumer sector, a<br />
defined electricity consumer is usually connected to the power<br />
supply which can normally handle a higher degree of voltage<br />
ripples or fluctuations, especially with regard to the two states<br />
of no load and full load.<br />
Industrial devices thus have to be prepared for any load, ie the<br />
power supply has to deliver a constant output voltage under all<br />
load conditions, and with minimum energy losses irrespective of<br />
their sensitivity to voltage fluctuations.<br />
Impressive result<br />
Measurements under real operating conditions have shown that<br />
the development of the regulated power supplies in the new<br />
product line, SITOP compact, has been more than successful.<br />
When compared to conventional power supplies, energy savings<br />
of approximately 28% during load operation and approximately<br />
53% during no-load operation were achieved. During normal<br />
use, characterised by a mix of load and standby operation, up to<br />
35% of energy can be saved. The SITOP compact power supplies<br />
are thus also optimally suited for supplying power to machines<br />
and plants that are in standby mode temporarily or for longer<br />
periods. Besides high energy efficiency and correspondingly<br />
low power dissipation during load and standby operation, the<br />
SITOP compact power supplies offer several other benefits.<br />
For instance, their compact construction (they measure from<br />
22.5 mm to 52.5 mm in width, which is up to 33% lower than<br />
During normal use, characterised by a mix of load and standby operation, the<br />
high energy efficiency of SITOP compact enables energy savings of up to 35%,<br />
compared to conventional power supplies.<br />
the widths of comparable power supplies) and their minimal<br />
generation of heat make them suitable for use in control boxes<br />
or small control cabinets in decentralised applications. The<br />
method of connecting them, via removable, screw-type plugin<br />
terminals, with spring-type terminals available as accessories,<br />
makes the power supplies user-friendly. On the one hand, this<br />
enables a pre-assembly of the wiring, and on the other, a very<br />
fast exchange of the device. And no tools are needed for the<br />
mounting to or removal from the DIN rail. As with all CE-, UL-,<br />
CSA- and ATEX- certified SITOP power supplies by Siemens,<br />
great importance was attached to reliability and availability<br />
during the development of the SITOP compact product line. At<br />
temperatures between -20 °C and +70 °C, the SITOP compact<br />
power supplies always reliably supply 24 V - even during brief<br />
power failures or overloads.<br />
Significant contribution towards energy savings<br />
Even power supplies with a low output and correspondingly<br />
low power dissipation<br />
can make a significant<br />
contribution towards<br />
energy savings, and the<br />
cost of the energy saved,<br />
can surpass the actual<br />
device price, depending<br />
on the operating mode<br />
and duration. For instance,<br />
large numbers of lowoutput<br />
power supplies are<br />
often used in the building<br />
automation of functional<br />
buildings. Just the control<br />
for the blinds of an office<br />
building utilises several<br />
The SITOP compact power supply is very<br />
efficient with regard to space and energy<br />
requirements.<br />
hundreds of such power supplies. Compared to conventional<br />
power supplies, using the new SITOP PSU100C in this application<br />
can result in energy savings of over 8000 kWh per year, which<br />
corresponds to a reduction in CO 2 emissions by about 5 t.<br />
SITOP PSU100C<br />
The new power supply series for the lower power range is<br />
especially suited for decentralised applications in control boxes<br />
or control cabinets.<br />

that the innovative technologies it offers are specified, installed,<br />
and maintained correctly.<br />
LGM has operations and projects in Singapore, Malaysia,<br />
Indonesia, Thailand, Vietnam, Philippines, China and Taiwan.<br />
The company is a member of the Singapore Green Building Council.<br />
Platinum-rated office in a Platinum-rated building<br />
The LGM headquarters is located in the Solaris building,<br />
at Fusionopolis.<br />
Designed by Dr Ken Yeang, the internationally renowned<br />
architect, famous for the concept of the ‘sustainable bioclimatic<br />
building’, Solaris, which was completed in October 2010, received<br />
the Green Mark Platinum Award from Singapore’s Building and<br />
Construction Authority.<br />
The LGM office takes up the mezzanine floor at Solaris,<br />
together with sister companies One For You (a luxury property<br />
developer) and Kaer (an Energy Services Company).<br />
The 8,000 ft 2 (740 m 2 ) completely open plan office encourages<br />

PRODUCTS REPRESENTED<br />
In order to ensure holistic building performance, LGM represents<br />
and works with various products that align with regional green<br />
schemes, covering all areas, including air-side energy efficiency,<br />
Indoor Air Quality (IAQ), energy and water monitoring, comfort,<br />
water efficiency, pumping efficiency, and lighting solutions.<br />
Euro Air<br />
The use of Euro Air systems is an alternative to traditional steel<br />
ducting and diffusers. Due to advances in technology, instead of<br />
transporting air through steel duct work, it is now possible to<br />
use ducts made of permeable fabric.<br />
The heat load calculations and equipment sizing remain the<br />
same as those for traditional systems, but instead of using metal<br />
ducts to transport the air, patented fabric ducts are used. This<br />
allows air-conditioning systems to be designed, which achieve<br />
better air distribution and save energy.<br />
Due to the ease of working with fabric, Euro Air systems can<br />
also be installed in a fraction of the time required to install<br />
traditional ducting, resulting in significant cost savings.<br />
Euro Air ducting has been used extensively in Singapore in a number<br />
of Green Mark projects (including in the Platinum-rated Rolls-<br />
Royce facility at Seletar Aerospace Park and in LGM’s Platinumrated<br />
office). By using Euro Air, it is possible for an air-conditioning<br />
system to save 10% to 40% of the energy consumption.<br />
Gelair<br />
Asian buildings are highly susceptible to mould and bacteria<br />
build-up. The hot and humid conditions mean that fresh air is<br />
continuously introduced into air-conditioned spaces, bringing<br />
with it warmth and moisture. Thi s air causes condensation,<br />
creating ideal conditions for bacteria and mould to grow.<br />
The use of Gelair is the simplest way to improve IAQ, by<br />
killing the mould, bacteria, and viruses that build up in airconditioning<br />
systems.<br />
It is a gel-based product that is placed in the AHU or FCU,<br />
where it delivers a patented, tea tree oil vapour throughout the<br />
air-conditioning system. Tea tree oil is a 100% natural essential<br />
oil, known for centuries to be a biocide that kills mould, bacteria,<br />
and viruses.<br />
Euro Air ducting has been installed in several Green Mark-rated projects in Singapore.<br />
Euro Air systems use ducts made of permeable fabric to transport air.<br />

SUSTAINABILITY<br />
Gelair delivers a patented, tea tree oil vapour throughout the air-conditioning system, which kills mould, bacteria, and viruses.<br />
Comparison of Gelair and UV technology.<br />
Gelair is used for three main reasons:<br />
• To improve the HVAC air-side efficiency. It does this by<br />
inhibiting biofilm build up on the cooling coil. This means there<br />
is less resistance in the system, so the fans do not need to<br />
work as hard, and, more importantly, it improves heat transfer<br />
on the coil surface.<br />
• To help customers achieve Green Mark certification. An IAQ<br />
audit makes up an important part of the Green Mark scheme.<br />
Many customers use Gelair to target key areas that may have<br />
failed an IAQ audit.<br />
• To further improve IAQ, Gelair kills mould, bacteria and viruses.<br />
This reduces the possibility of the Sick Building Syndrome,<br />
increases productivity, reduces sick leave, and gets rid of<br />
musty smells.<br />
Switch<br />
Switch provides real-time energy and water monitoring that can<br />
be accessed anytime from anywhere in the world. As a result,<br />
information on the use of these resources is communicated beyond<br />
BMS rooms and board rooms, to occupants of a building who can<br />
then easily see their consumption habits and take appropriate<br />
measures where necessary.<br />
There are two main differences between Switch and other<br />
energy monitoring systems.<br />
• Switch is hardware-neutral. This means it can get energy data<br />
from any power meter or even a BMS. This drastically reduces<br />
installation time and cost, and gives the flexibility to work with<br />
existing hardware.<br />
• Switch is cloud-based. This means the data can be viewed on<br />
consumer-friendly devices from anywhere in the world, such<br />
as a computer, smart phone, or iPad.<br />
With Switch, real-time energy and water monitoring data can be accessed from a<br />
computer, smart phone, or iPad.<br />

SUSTAINABILITY<br />
Krantz<br />
Krantz provides a wide range of air diffusers (ceiling, sidewall,<br />
floor, displacement, assembly, linear, radial) as well as radiant<br />
cooling equipment (chilled beams/ceilings).<br />
In designing the HVAC systems for a building, time and resources<br />
are deployed to ensure that the AHUs have the right capacity,<br />
ducting networks are optimised, and diffusers are appropriately<br />
placed to get air into rooms.<br />
Krantz has taken this one step further.<br />
The diffuser is not the only consideration. The conditions in<br />
the room should be of equal concern. Often, in hotels, meeting<br />
rooms, lobbies, libraries, and airports, although everything looks<br />
perfect, it can be very cold at certain locations because of ‘cold<br />
dumping’, or locations can be ‘hotspots’, with little air movement.<br />
This is what Krantz has focused on eliminating, in its approach<br />
to developing air diffusers. When air comes out of a Krantz<br />
diffuser, it mixes with air in the room, resulting in the correct<br />
temperatures and air velocities throughout the entire space.<br />
RESEARCH & DEVELOPMENT<br />
LGM does not restrict its scope of work to product distribution.<br />
As well as providing consultation and turnkey services, LGM also<br />
works with product developers and manufacturers to design<br />
products for the Asian region.<br />
Currently LGM is running an energy efficiency study and a<br />
proof-of-concept study. One is for a European manufacturer<br />
looking for energy efficiency data in Asia, and the other is on<br />
a cooling coil treatment technology to be launched next year.<br />
PASSION FOR GREEN BUILDING<br />
TECHNOLOGY<br />
For LGM, going green and embracing green technology is about<br />
doing things differently so that better buildings are built with<br />
less resources. Saving the environment is a by-product of true<br />
building performance.<br />
The company believes that in order to build green buildings, it is<br />
not correct to just take the template from the previous project<br />
and bolt on some green features. Instead, it is necessary to relook<br />
at fundamentals for each project. This makes the company’s<br />
solutions more appealing to clients and results in maximum<br />
efficiency.<br />
CLIENTS<br />
LGM has projects and partners in all Asian countries and has<br />
even managed projects as far afield as the Middle East.<br />
Among the company’s customers are Keppel FMO, Dyson,<br />
EMAS, Rolls-Royce, Halliburton, Ngee Ann Polytechnic,<br />
M Hotel, Trisara Resort, Canadian International School, St<br />
Joseph’s Institution International, United World College, Aviva,<br />
and Salvation Army.<br />

PROJECT APPLICATION<br />
Saving energy in a manufacturing plant<br />
An electrical and thermal energy audit led to the adoption of several measures that<br />
yielded positive results.<br />
SCPL manufactures spray-dried, non-dairy creamers. Image by SCPL.<br />
Super Continental Pte Ltd (SCPL) is a Singapore-based manufacturer<br />
of specialised ingredients for instant beverages. Currently, the<br />
company focuses on producing spray-dried, non-dairy creamers.<br />
SCPL had already implemented some energy conservation<br />
measures at its plant, such as installing motion sensors, variable<br />
speed drives in air compressors, and new energy-efficient LED<br />
tube-lights at some locations. Although the efforts taken by the<br />
plant for conserving electricity were commendable, there were<br />
still some areas that could be addressed in order to realise more<br />
energy savings.<br />
The contracted demand for the plant is 1,100 KW and its annual<br />
electricity consumption is 6,360 MWh.<br />
SCPL wanted the services of energy consultants who could<br />
provide a utility bill analysis and identify opportunities for energy<br />
savings in the plant, focussing on major energy consuming areas<br />
like water cooled chillers, chilled and condenser water pumps,<br />
cooling towers, air compressors, high pressure pump, diesel fired<br />
boiler, and lighting.<br />
The solution<br />
Siemens Pte Ltd conducted an electrical and thermal energy<br />
audit for SCPL. The objective of the study was to identify the<br />
major energy consuming equipment, understand the operation<br />
of the utility systems and plant, shortlist potential energy<br />
saving areas, and determine possible energy savings from these<br />
areas. SCPL selected Siemens for the energy audit because<br />
of the technical capabilities of Siemens in the electrical and<br />
thermal areas.<br />
Special attention was given by Siemens to SCPL’s base load and<br />
the production-dependent load. Existing savings potential was<br />
estimated and integrated in the final Energy Efficiency Report<br />
which contains:<br />
• An overview of energy efficiency measures and optimisation<br />
potentials.<br />
• First estimation of the potential energy savings, the necessary<br />
investment for each efficiency measure, and the resulting ROI.<br />
Some of the measures were implemented immediately and<br />
others are in the process of implementation.<br />
The result<br />
Based on the detailed energy study carried out, 10 projects with<br />
energy savings amounting to 1,375 MWh (corresponding to energy<br />
cost savings of S$ 355,700 per annum) were identified for SCPL.<br />
The implementation of the proposed energy saving measures will<br />
bring a reduction of 9.9% in the existing utility bills. The ROI ranges<br />
from 1.1 years to 6.2 years, with a mean value of 3.3 years.<br />
Furthermore, an environment-friendly refrigerant is being used<br />
in the new chiller. The replacement of the old chiller has resulted<br />
in monthly energy savings of 48,000 KWh.<br />

EVENTS<br />
Singapore takes the lead in exploring integrated<br />
solutions for global cities<br />
An overview of last year’s Water Expo.<br />
Singapore is taking the lead in encouraging cities to find new<br />
integrated solutions in resolving pressing urbanisation challenges<br />
around the world. The third edition of the World Cities Summit,<br />
the fifth Singapore International Water Week, and the inaugural<br />
CleanEnviro Summit Singapore will be held together from 1 to<br />
5 July 2012, at Sands Expo & Convention Center, Marina Bay<br />
Sands, Singapore.<br />
The three events provide an integrated global platform for<br />
government and industry leaders to share solutions for<br />
sustainable urban development and the latest innovations in<br />
water and clean environment solutions.<br />
The co-location of the three events will enable exhibitors and<br />
participants to explore synergies, network and forge partnerships<br />
with a wider range of global industry leaders, policy makers and<br />
experts. Together, the three events will showcase Singapore’s<br />
global thought leadership in sustainable development.<br />
Some 15,000 high-level visitors and delegates are expected<br />
to attend. Prominent mayors and government and industry<br />
leaders will speak on wide-ranging topics like investing in cities,<br />
smart cities of the future, water planning for sustainable and<br />
liveable cities, and urbanisation trends and challenges in the<br />
next 20 years.<br />
Cutting-edge technologies and best practice models will<br />
be showcased on water, waste management and urban<br />
planning, with integrated solutions perspectives. New business<br />
partnerships may be formed, with the three events enabling<br />
government officials and industry solutions providers to discuss<br />
financing models and new business ventures.<br />
NEW FOCUS ON INTEGRATED SOLUTIONS<br />
Integrated solutions is the new focus for these three events. It<br />
is no longer enough to invest in separate solutions on water,<br />
environment or waste. Cities are increasingly taking on a<br />
more holistic approach to tackling urbanisation challenges, for<br />
sustainable growth and a better quality of life for all.<br />
Singapore is taking the opportunity to facilitate greater<br />
discourse and action in this important area with the co-location<br />
of these three global events. It is already making inroads in<br />
integrated solutions with its comprehensive, long-range and<br />
holistic approach in urban planning, combining it with resourceefficient<br />
policies and technologies. It has also been researching<br />
and test-bedding ideas for new urban solutions that can be<br />
commercialised and replicated elsewhere. They cover six areas<br />
- green buildings, energy, waste and water management, usage<br />
of technology for public safety, green networks, and developing<br />
smart transport systems.<br />
Explaining the reason to hold all three events together, Mr Khoo<br />
Teng Chye, Executive Director of the Centre for Liveable Cities<br />
said, “The World Cities Summit and the Singapore International<br />
Water Week are already established events on the global<br />
calendar. Their co-location this year along with the inaugural<br />
CleanEnviro Summit Singapore is just one of the ways in which<br />
Singapore is taking the lead to find new and more holistic ways<br />
to achieve clean and sustainable development for global cities.<br />
By holding the three events together, we are able to offer a<br />
truly integrated platform for the first time, for world leaders to<br />
discuss challenges, opportunities and share best practices for<br />
sustainable and liveable cities of the future”.<br />

EVENTS<br />
Mr Ng Lang, Chief Executive Officer of the Urban Redevelopment<br />
Authority said, “The World Cities Summit has been attracting<br />
top government and industry leaders from around the world<br />
since it started in 2008. The third run this year is taking place<br />
at an exciting time when the pace of urbanisation in the region<br />
is accelerating, and cities are looking for solutions to address<br />
urbanisation challenges. Topics discussed are on the pulse of<br />
challenges cities are facing. Discourse is expected to be richer<br />
and more in-depth, with new insights on the future of sustainable<br />
cities. We also hope to facilitate meaningful dialogue between<br />
government and industry providers to find new business and<br />
collaboration opportunities in integrated solutions”.<br />
Representing the Singapore International Water Week, Mr Chew<br />
Men Leong, Chief Executive of PUB, Singapore’s national water<br />
agency, said, “This strategic co-location of the three events allows<br />
for an integrated look at the co-creation of water solutions in<br />
the broader context of sustainable and liveable cities which<br />
will offer participants richer discussions and more networking<br />
opportunities. Henceforth, SIWW will also move in sync with<br />
the co-location of the three events on a biennial basis, to provide<br />
a holistic and integrated approach in co-creating solutions for<br />
sustainable urban development, and deliver even greater value<br />
to our delegates. This also provides greater opportunities for<br />
cross pollination of ideas and technologies, access to integrated<br />
solutions as well as outreach to a wider pool of policy-makers,<br />
industry players and other key stakeholders. We have sought<br />
preliminary feedback from our partners and stakeholders and<br />
they are supportive of a biennial event”.<br />
“The overall outlook for the global water industry is positive,<br />
with innovation/R&D, industrial water solutions and water reuse<br />
as the key growth areas. SIWW has managed to ride on this<br />
growth - we welcomed 13,500 participants from 99 regions/<br />
countries in 2011, a growth of almost 60% from the inaugural<br />
event in 2008”, added Mr Chew.<br />
Mr Andrew Tan, Chief Executive Officer of the National<br />
Environment Agency said, “Awareness of the environment<br />
is growing in Asia and Singapore is well-positioned to foster<br />
greater dialogue and cooperation in this area. The inaugural<br />
CleanEnviro Summit Singapore hopes to provide such a<br />
platform for high-level decision makers, regulators, industry<br />
players as well as community stakeholders to come together to<br />
develop practical and innovative solutions for sustainable growth.<br />
In particular, growing waste volumes in the region as a result<br />
of rapid urbanisation and growing affluence and unsustainable<br />
waste management practices could undermine the quality of<br />
life in the region. We hope that through the unique combination<br />
of CleanEnviro Summit Singapore and WasteMET Asia, we can<br />
promote better waste management practices and encourage<br />
greater use of waste as a resource in the region. We believe<br />
that both growth and sustainability can co-exist if we adopt an<br />
integrated approach to development”.<br />

EVENTS<br />
POWER-GEN Asia returns to Bangkok for annual<br />
gathering of power industry professionals<br />
POWER-GEN Asia, the region’s premier conference and<br />
exhibition for the power generation, transmission and<br />
distribution industries, will return to Bangkok, Thailand, from 3<br />
to 5 October 2012.<br />
For its 2012 presentation, the event will have the support<br />
of Thailand’s top industry utilities, government energy<br />
organisations, and industry trade bodies.<br />
POWER-GEN Asia 2012 has the endorsement of the Ministry<br />
of Energy, Electricity Generating Authority of Thailand, Provincial<br />
Electricity Authority, Metropolitan Electricity Authority and PTT.<br />
This is complemented by the support of top organisations<br />
such as the Asian Institute of Technology, Consulting Engineers<br />
Association of Thailand and Independent Power Producers<br />
Forum (IPPF).<br />
Event Director, Mr Glenn Ensor, said, “We are delighted that<br />
POWER-GEN Asia will be returning to Thailand from 3 to 5<br />
October 2012. In 2009, we enjoyed the most successful event<br />
during the event’s history. The enthusiasm and support of<br />
the Thai industry and authorities will ensure the success of<br />
POWER-GEN Asia and we hope to break more records for<br />
the event in Bangkok this October”.<br />
Towards a secure energy future<br />
Thailand’s GDP is predicted to see a 5.6% growth, leading to a<br />
6% growth in peak power demand between 2012 and 2016, to<br />
35,600 MW and this figure is expected to reach 42,000 MW<br />
by 2021. With current capacity of around 28,500 MW, and<br />
despite energy imports from neighbouring countries, Thailand<br />
will see a shortfall in power supply in the next few years.<br />
The Electricity Generating Authority of Thailand generates<br />
around 50% of Thailand’s electricity and expects to invest<br />
around 100 billion Baht (US$ 3.5 billion) in energy markets in<br />
the coming years, as the Ministry of Energy looks to address<br />
the energy security issues.<br />
Thailand wants to be a leading country in exporting carbon<br />
credits in Asia, by developing carbon capture and storage<br />
(CCS) technologies, and thereby enabling the country to<br />
submit energy projects for certification under the Clean<br />
Development Mechanism (CDM), to the extent of one million<br />
tons CO 2 per year.<br />
Despite putting on hold the building of nuclear plants, for three<br />
years, whilst a review is undertaken, Thailand is still interested<br />
in pursuing this option, with the Ministry of Energy looking to<br />
undertake a detailed feasibility study on the development of<br />
nuclear power plants, using relevant IAEA guidelines.<br />
As a net importer of energy, Thailand is central to the power<br />
development plans of the region which is undergoing rapid<br />
change and which has attracted US$ 100 billion of investment<br />
in the energy industry and its infrastructure.<br />
Conferences and exhibitions<br />
The POWER-GEN Asia conference is a key forum for senior<br />
executives, industry leaders and senior <strong>engineer</strong>s to discuss<br />
a range of important topics, the latest issues, and solutions,<br />
in order to meet the challenge of the growing demand for<br />
electricity in the region.<br />
Conference Director, Mr Nigel Blackaby, said, “The recent<br />
developments in the region, especially the impact of last year’s<br />
floods and the damage to the Thai infrastructure, have given<br />
the industry much to discuss in terms of the options available<br />
to meet shortages of power”.<br />
“Thailand is well positioned with diverse options, from<br />
traditional fuels to renewable energy, but is the rest of the<br />
region set to overcome these challenges? We look forward to<br />
some lively and interesting debates at this year’s POWER-GEN<br />
Asia conference”, he added.<br />
The new Challenger Hall 1 at the IMPACT Exhibition &<br />
Convention Center in Bangkok, will host POWER-GEN Asia<br />
2012 and the co-located Renewable Energy World Asia 2012<br />
conferences and exhibitions.<br />
Organised by PennWell Corporation, POWER-GEN Asia<br />
2012 and Renewable Energy World Asia 2012 are expected<br />
to attract around 7,000 industry professionals.<br />

Honeywell introduces Attune Advisory Services<br />
Honeywell has introduced its new Attune Advisory Services, a<br />
suite of professional services that combines cloud-based tools<br />
and analytics with a global network of operations centres, and<br />
energy and facility experts, to provide enhancements that can<br />
reduce utility bills and operating expenses by up to 20%.<br />
Attune Advisory Services help building owners, wherever<br />
they are on the energy- and operational-efficiency spectrum,<br />
providing technology and support to gain baseline awareness<br />
of building performance, make improvements to reduce<br />
energy and operations costs, and define an ongoing strategy<br />
to manage and optimise a facility.<br />
“The performance of building systems and equipment can<br />
degrade by as much as 5% every year, which translates to<br />
energy and operating costs that continually escalate”, said Mr<br />
Paul Orzeske, President of Honeywell Building Solutions.<br />
performance and create a baseline to help identify savings<br />
opportunities.<br />
Honeywell also provides lobby signage that allows organisations<br />
to showcase the results of their efficiency efforts in clear-cut,<br />
graphics-driven terms, helping to educate occupants, and<br />
spurring them to alter their behaviour and energy use.<br />
Attune Energy Improvement<br />
Energy Improvement turns building data into actionable<br />
recommendations with the advice of Honeywell’s experienced<br />
analysts. Facility managers receive periodic reports that<br />
provide information on efficiency opportunities with related<br />
recommendations on upgrades and replacements. Building<br />
retrofits made as a result of these services can deliver energy<br />
savings of up to 10%, potentially paying for themselves<br />
within months.<br />
“Companies are starting to realise the significant impact this<br />
can have, as well as the opportunity it presents for bottomline<br />
savings. With Attune, we are providing the ease and<br />
convenience of cloud-based technology with expert advice<br />
and actionable guidance so companies can capture and<br />
maintain those savings”, he added.<br />
Facility managers are under increased pressure to go beyond<br />
simply monitoring building systems and providing base-level<br />
comfort. They are being asked to translate facility information<br />
into actions that deliver energy, operational and environmental<br />
outcomes. However, many do not have the resources to<br />
assess building performance, identify opportunities to upgrade<br />
infrastructure and operations, or prioritise retrofits.<br />
Attune Advisory Services turn building performance data into<br />
an action plan that pinpoints potential upgrades and their<br />
expected return on investment. The service suite enables facility<br />
managers to optimise their budgets, personnel and systems,<br />
by combining powerful cloud-based tools and analytics with<br />
insight and advice from a global team of Honeywell consultants,<br />
and customised support provided by skilled onsite technicians.<br />
The services exceed typical facility management software<br />
which often only provides a steady stream of data, but no insight<br />
or recommendations. Attune offers three levels of assistance<br />
(awareness, improvement and optimisation) with programmes<br />
focusing on either energy or operational efficiency.<br />
Attune Energy Awareness<br />
Energy Awareness enables facility managers to access and<br />
monitor electricity and natural gas consumption using a<br />
web-based, software-as-a-service dashboard that collects<br />
information from utility meters, to provide insight on building<br />
Attune Energy Optimisation<br />
Energy Optimisation delivers a powerful combination of<br />
improved building knowledge and actionable recommendations,<br />
backed by detailed monitoring, measurement and verification,<br />
to help ensure facilities operate at their peak. Optimisation<br />
can deliver energy savings of 10% to 20% on average, with the<br />
potential for even greater savings in older facilities.<br />
Honeywell plugs into a building to gather systems data and<br />
assess performance using cloud-based fault detection and<br />
diagnostics. Local service technicians collaborate with a global<br />
team of optimisation experts to review the findings and present<br />
a plan to help facility managers reduce utility consumption.<br />
Ongoing assessment and monitoring allow building owners to<br />
see that upgrades continue to deliver results to the bottom<br />
line.<br />
Attune Operations Services<br />
The goal of Operations Services is more efficiently run buildings.<br />
Facility managers can select different combinations of 24/7<br />
equipment monitoring, remote and onsite response to alarm<br />
conditions, and Honeywell consultation, for uncovering other<br />
potential improvements and lowering equipment life-cycle<br />
costs. By providing secure, cloud-enabled support, Honeywell<br />
is able to help address the issues building operators routinely<br />
face - assistance the company is already providing to more<br />
than 3,000 sites that are connected to its global operations<br />
centres.<br />
Attune Operations Services provide guided solutions aimed<br />
at saving money and reducing downtime, and the improved<br />
insight allows Honeywell to dispatch technicians only when<br />
needed. It is a cost-effective way to improve overall efficiency<br />
and another step toward optimisation.<br />

Schneider Electric releases new range of circuit<br />
breakers and control unit<br />
Schneider Electric recently announced the release of the<br />
EasyPact CVS range of Class II moulded case circuit breakers<br />
(MCCB) for low-voltage applications from 100 Amps to 630<br />
Amps. Designed to meet the requirements of the majority of<br />
common protection applications in medium-sized commercial<br />
and industrial buildings, the new circuit breakers deliver a level<br />
of performance and cost-saving functionality that is unusual in<br />
their price range. Adjustable thresholds and a service breaking<br />
capacity rated at 100% of the ultimate breaking capacity<br />
enhance the reliability and life cycle of the products while<br />
reducing servicing costs. Their compact, modular design and<br />
field-installable accessories shared with other offered ranges<br />
help to simplify ordering, stocking, and installation.<br />
“Around the globe, construction and upgrade budgets have<br />
become much tighter. The new EasyPact CVS range of circuit<br />
breakers will help panel builders adapt to customers’ budgets<br />
while delivering required capabilities and the brand quality of<br />
a global leader in energy management and protection”, said<br />
Mr Kresna Widodo, Country Marketing Director for Schneider<br />
Electric Singapore.<br />
“The range leverages our expertise in precision design and<br />
manufacturing, delivering exceptional value to our customers”,<br />
he added.<br />
Schneider Electric has designed the EasyPact CVS range to be<br />
simple and safe during installation, operation, and maintenance.<br />
The robust circuit breakers are suitable for isolation, guaranteed<br />
to the IEC 60947-2 standard, and provide a highly visible<br />
and lockable contact position indicator to ensure operator<br />
confidence. Extended current limiting and thermal protection<br />
can greatly reduce the stresses on equipment, due to short<br />
circuits and their associated effects. Earth leakage protection<br />
can be added by installing a Vigi CVS option module. In the<br />
event of a circuit fault, simple visual indicators help maintenance<br />
personnel quickly locate the tripped breaker and take steps to<br />
correct the problem.<br />
To ensure a low total cost of ownership, the EasyPact CVS range<br />
features a modular design that adapts to changing needs. Basic<br />
accessories and a logical part numbering scheme are shared<br />
with the rest of the Schneider Electric MCCB family, helping<br />
to optimise stocking while reducing effort and the potential<br />
for ordering errors. Products in the EasyPact CVS range also<br />
feature a compact footprint similar to other Schneider Electric<br />
MCCB ranges, which can help reduce switchboard dimensions<br />
and installation times.<br />
Manufactured from premium materials in ISO 9001 and ISO<br />
14000 certified production plants, the EasyPact CVS range<br />
of circuit breakers are fully tested and certified by national,<br />
international, and third-party organisations to all relevant safety<br />
standards. Reflecting the company’s comprehensive approach<br />
to environmental responsibility, the products comply with all<br />
environmental standards for manufacturing, including RoHS and<br />
REACH, and are <strong>engineer</strong>ed for easy disassembly and recycling.<br />
The EasyPact CVS range of circuit breakers is available now<br />
from Schneider Electric.<br />
Meanwhile, the company has also released the Micrologic E control<br />
unit as an option for the company’s Masterpact and Compact NS<br />
ranges of circuit breakers. While featuring the same protection<br />
functions and ‘ammeter’ current measurement capabilities as<br />
the best-selling Micrologic A control unit, the new Micrologic<br />
E adds energy measurement at a low incremental cost. This<br />
capability enables energy metering at key points throughout an<br />
electrical distribution system, supporting efforts to reduce energy<br />
consumption, energy-related costs, and green house gas emissions.<br />
Ideally suited to applications in office buildings, hospitals, data<br />
centres, or any commercial or industrial facilities, the Micrologic E<br />
can be installed in new or existing circuit breakers. Energy data can<br />
be viewed by facility managers or maintenance personnel through<br />
the integrated LCD display, an optional front-panel display module,<br />
or over a communications network using Schneider Electric or<br />
third-party software.<br />
“Energy metering is a key first step towards energy efficiency, and<br />
we believe intelligent, energy measurement-capable breakers<br />
will soon become the industry standard”, said Mr Widodo.<br />
“We were the first company to introduce affordable energy<br />
measurement in a circuit breaker with the Compact NSX range.<br />
The Micrologic E control unit extends this same capability across<br />
the Compact NS and Masterpact ranges, giving customers a<br />
smart, cost-effective alternative to installing a separate power<br />
meter. This puts energy metering in more places where it is<br />
needed, helping customers isolate where and when the most<br />
energy is being consumed or wasted”, he added.<br />
The Micrologic E is the newest addition to the established<br />
Micrologic series of circuit breaker control units, bridging the<br />
gap in functionality between two lower and two higher models,<br />
and offering measurements of energy (at 2% accuracy), current,<br />
voltage, and active power, at an attractive price point. All<br />
Micrologic models feature an internal architecture that safely<br />
and reliably separates protection and measurement functions.<br />
The Micrologic E also introduces a LCD ‘auto-scroll’ function<br />
that enables personnel to safely view all the most important<br />
measurements without having to touch the circuit breaker. A<br />
new trip history supports fast troubleshooting by storing, in onboard<br />
memory, the trip type, date, and timestamp for the last<br />
10 trip events, while two programmable relay outputs can be<br />
controlled by trip events.<br />
Also being introduced is a BCM ULP communications module<br />
option for Compact and Masterpact circuit breakers that enables<br />
connection of an FDM121 display for convenient local viewing<br />
of energy or other measurements on the door of an electrical<br />

Schneider Electric introduces the Acti 9<br />
modular systems<br />
Schneider Electric, a pioneer in low voltage modular systems,<br />
recently announced the release of the Acti 9, which is claimed<br />
to be the safest, simplest and most efficient modular system for<br />
final distribution for tertiary and industrial building applications.<br />
The company is taking advantage of its five generations of industry<br />
experience to introduce industry-first innovations and enhance its<br />
technological leadership in this field.<br />
Designing, maintaining or upgrading an industrial low voltage<br />
installation can be a demanding task, and electricians are on the<br />
front lines. Their job is to ensure every installation operates<br />
smoothly - for the entire life cycle of the installation. ‘Schneider<br />
Electric understands this’, says Mr Kresna Widodo, Country<br />
Marketing Director for Schneider Electric Singapore.<br />
“That is why we designed the Acti 9, the most complete modular<br />
system with our customers in mind. It is <strong>engineer</strong>ed to guarantee<br />
safety, deliver savings in terms of time and money and ensure that<br />
installation starts with the right products. The Acti 9 provides the<br />
right solution for every application”, he added.<br />
What distinguishes the Acti 9 system are its innovative features that<br />
provide many benefits to the industry. For example, it offers a high<br />
level of safety. Its VisiSafe feature provides reinforced insulation on<br />
the iC60 miniature circuit breaker and iID residual current circuit<br />
breaker ranges. It guarantees the downstream circuit is always safe,<br />
regardless of overvoltage conditions, wear or operator experience,<br />
even in the most demanding industrial environments. Combined<br />
with its Class 2 front face, where clearances between Acti 9 surfaces<br />
and internal parts are more than twice the industry standard, it<br />
exceeds even the most demanding safety requirements.<br />
The Acti 9 also provides high efficiency for day-to-day operations.<br />
VisiTrip is a feature that lets customers identify a fault in a single<br />
glance, allowing quick diagnosis, resolution and reclosure of circuits<br />
for easier building management and reduced downtime. In addition,<br />
the super immunisation of its RCDs guarantees the highest continuity<br />
of service and electrical immunity, especially in critical power<br />
applications, or where switchgear encounters electromagnetic or<br />
chemical interference. The Acti 9 also introduces a new automatic<br />
recloser auxiliary (ARA iC60) that limits intervention costs on<br />
distant infrastructure sites. Such efficiency allows for easier building<br />
management, eliminates downtime and makes businesses even<br />
more competitive.<br />
The Acti 9 is an efficient modular system for final distribution for tertiary and industrial building applications.<br />

First Public-Private Collaboration initiative for<br />
green building research<br />
The Agency for Science, Technology and Research (A*STAR);<br />
Building and Construction Authority (BCA); and the Ministry<br />
of National Development (MND) have jointly awarded<br />
funding for nine projects in a pilot green building grant call to<br />
encourage research and greater adoption of green building<br />
technologies. Launched in April 2011, the grant call is the first<br />
of its kind structured to foster Public-Private Collaboration<br />
(PPC) in green building research.<br />
The green building joint grant call fosters collaboration<br />
between public research institutions and companies through<br />
joint R&D projects. Under the PPC arrangement, public<br />
research institutions partner at least one related industry<br />
organisation as co-investigator. This creates synergies as<br />
public research institutions are able to tap on the industry’s<br />
experience and network, while companies leverage on the<br />
research expertise and cutting edge infrastructure within<br />
public research institutes, to develop deployable green<br />
building technologies.<br />
The nine awarded projects will support the development of<br />
technologies in two key areas - energy efficiency and building<br />
facade materials. These include energy-efficient technologies<br />
that reduce the amount of heat penetration into buildings<br />
and innovative air-conditioning technologies that require less<br />
energy for cooling and help optimise energy management<br />
in buildings. Consequently, the projects may bring about<br />
substantial savings for building operators and dwellers<br />
through greater energy efficiency.<br />
Mr Tay Kim Poh, Deputy Secretary (Development) of MND,<br />
and Chairman of the MND R&D Steering Committee, said,<br />
“The strong response of over 50 submissions is encouraging.<br />
Just as A*STAR, BCA and MND joined hands to launch this<br />
grant call, it is heartening to see that many public research<br />
institutions and companies have come together in the same<br />
spirit of collaboration. This is the first such initiative involving<br />
both the government and the private sector for green<br />
building research. We hope to see more of such collaborative<br />
efforts when the second grant call is launched later this year,<br />
so that more ideas can be translated into innovations to<br />
meet urbanisation challenges”.<br />
Welcoming the awards given for this grant call, Dr Raj<br />
Thampuran, Executive Director, Science and Engineering<br />
Research Council of A*STAR, said, “Through such PPC<br />
initiatives, public research institutions and companies can<br />
leverage on each other’s strengths and expertise to develop<br />
technologies that could potentially generate impactful<br />
environmental, economic and social benefits. The benefits in<br />
the area of green building technologies are manifold, and can<br />
be illustrated through outcomes such as potential reduction<br />
in energy use for building operators and dwellers”.<br />
Dr John Keung, CEO of BCA added, “While BCA has made<br />
good progress in greening the built environment in Singapore<br />
through various initiatives under our Green Building<br />
Masterplan, we need to continuously push the frontiers of<br />
green buildings through R&D. On this front, BCA led the<br />
inter-agency Green Building R&D Workgroup to develop<br />
the Green Building R&D Framework in identifying key focus<br />
areas for R&D, with an emphasis on developing high-impact,<br />
cost-effective solutions for green buildings in the tropics. We<br />
believe that the success of this pilot grant call with A*STAR<br />
and MND will pave the way for future R&D grant calls and<br />
build Singapore’s capability in green building research”.<br />
Following the success of the pilot green building joint grant<br />
call, the second green building joint grant call is projected to<br />
open in the third quarter of 2012.<br />
Singapore Green Building Council signs MOU<br />
with Indonesian counterpart<br />
The Singapore Green Building Council (SGBC) recently<br />
signed a Memorandum of Understanding (MOU) with<br />
Green Building Council Indonesia (GBCI) to collaborate<br />
on certification and training to enhance the green<br />
building landscape in both countries.<br />
This is SGBC’s second MOU with regional counterparts<br />
since the start of this year. The first was with China<br />
Green Building Council (CGBC), which was signed in<br />
March.<br />
Under the MOU with GBCI, both SGBC and GBCI<br />
will work towards recognition of the Singapore Green<br />
Building Product Certification (SGBP) scheme under the<br />
Green Building assessment scheme of Indonesia. SGBC<br />
intends to certify up to 50 products from Indonesia<br />
under its SGBP certification scheme by 2013.<br />
The two parties will also cooperate in the area of<br />
training. This will cover relevant Green Buildingrelated<br />
professional training and study trips during<br />
which Indonesian participants will gain knowledge of<br />
Singapore’s successful practices via proven case studies<br />
and visits to relevant projects.<br />
Both SGBC and GBCI will also explore various other<br />
activities and avenues to collaborate in the area of<br />
green building development and services in Indonesia<br />
and Singapore.<br />

WWEA releases Small Wind World<br />
Report 2012<br />
On the occasion of the 3 rd World Summit for Small Wind<br />
during the New Energy fair in Husum Germany, in March this<br />
year, the World Wind Energy Association (WWEA) released its<br />
first Small Wind World Report. For the first time, data about<br />
the status of small wind turbines all over the world has been<br />
collected and published.<br />
The total number of small wind turbines installed world-wide<br />
reached 656,000 units as at the end of 2010, after 521,000<br />
in 2009 and 460,000 in 2008. These small wind turbines<br />
represent a total capacity of around 440 MW (at the end of<br />
2010), compared with a total capacity of 240 GW of large<br />
wind turbines.<br />
The largest share of small wind turbines are in China and the US,<br />
followed by installations in the medium-sized markets of the UK,<br />
Canada, Germany, Spain, Poland, Japan and Italy.<br />
WWEA expects that, in 2020, the total installed small wind<br />
capacity will reach 3,800 MW, representing an almost ten-fold<br />
increase compared with 2010. The market for new small wind<br />
turbines will have a volume of around 750 MW in the year 2020.<br />
Today, more than 330 manufacturers of small wind turbines have<br />
been identified in 40 countries on all continents, and another<br />
estimated 300 companies are manufacturing equipment for<br />
the small wind industry. Most of the manufacturers are still<br />
small- and medium- sized companies. More than half of these<br />
manufacturers can be found in only five countries, namely China,<br />
USA, Germany, Canada, and the UK.<br />
In spite of a vibrant small wind sector in many countries, only<br />
few governments are offering specific support policies for small<br />
wind. Less than 10 countries are offering sufficient feed-in tariffs<br />
for small wind, and there is almost a complete lack of support<br />
schemes in the developing countries, where the demand for<br />
small wind turbines would be huge, especially in non-electrified<br />
areas. Only in China, small wind turbines contribute today on<br />
a large scale to rural electrification, which is also due to the<br />
relatively modest price level of small wind turbines in the country.<br />

to the LTA Cares Fund, which reaches out to the financially<br />
and physically disadvantaged to help them with their daily<br />
transport needs. In total, S$ 200,000 was raised this year.<br />
Since 2007, LTA, together with partners and staff, have<br />
contributed S$ 750,000 to the LTA Cares Fund.<br />
Land Transport Excellence Awards<br />
The biennial Land Transport Excellence Awards (LTEA) was<br />
inaugurated in 2008 by the Land Transport Authority to<br />
recognise industry partners and individuals who have made<br />
significant contributions to Singapore’s land transport.<br />
Award recipients represent the best in their respective fields<br />
of expertise and help set new benchmarks for the industry.<br />

ABB announces new regional hub in Singapore<br />
for data centre technology<br />
ABB, a leading power and automation technology group,<br />
announced recently that the company will create a regional hub<br />
for data centre solution development and support in Singapore.<br />
This will be ABB’s first regional hub for data centre technology<br />
in the Asia Pacific market.<br />
The new hub will focus on the company’s recently introduced<br />
Decathlon suite of software, hardware, and services for data<br />
centre management. Decathlon analyses a variety of data such<br />
as IT load patterns, weather forecasts, contract and utility rate<br />
data, to predict and adjust energy consumption to ensure data<br />
centres are more reliable and energy-efficient. This new green<br />
technology can provide potential energy savings of 10% to<br />
50%, and is expandable across multiple sites, which can result in<br />
savings worth millions of dollars for some enterprises, each year.<br />
“Singapore’s thriving internet economy, robust infrastructure,<br />
availability of talent, and the country’s business-friendly<br />
environment are some of the reasons ABB chose to invest in<br />
Singapore”, commented Mr Tobias Becker, Head of the Control<br />
Technologies business in the ABB Group.<br />
“Singapore is already a global data management hub and holds<br />
about 50% of Southeast Asia’s data centre capacity. We are<br />
confident that basing our regional hub in Singapore will best<br />
serve our customers in Asia Pacific”, he added.<br />
Digital information is now synonymous with electrical power.<br />
With the rise in internet use and cloud computing, data centres<br />
are rapidly expanding in size, creating a significant environmental<br />
and energy usage footprint. Data centres consume vast amounts<br />
of energy every year. Size for size they consume around 30<br />
times the power, or more, required to run the average office<br />
building. In total, global consumption amounts to a staggering<br />
80 million megawatt hours of electricity a year. Singapore’s own<br />
data centre capacity is projected to increase by 50% over the<br />
next few years, from 2.4 million ft 2 (223,000 m 2 ) in 2010 to 3.6<br />
million ft 2 (335,000 m 2 ) in 2015.<br />
In addition to Decathlon, ABB provides a wide range of products,<br />
integrated solutions and expertise to ensure that data centres<br />
operate with optimum reliability and efficiency. For AC and DC<br />
