Mr Graham huxley AM<br />
Welcome to the Spring 2010 edition<br />
of the <strong>Australian</strong> <strong>Building</strong> Regulation<br />
Bulletin.<br />
In response to the 2009 Victorian<br />
Bushfires Royal Commission, ABCB has<br />
completed the development of a new<br />
national standard for the design and<br />
construction of bushfire shelters for<br />
personal use. The new performance<br />
standard has been released and is<br />
available for use by State and Territory<br />
regulators. The Bushfires Royal<br />
Commission has also released its final<br />
report and we are responding to the<br />
issues it has raised.<br />
The <strong>Building</strong> Ministers’ Forum (BMF) met<br />
early July to consider the ABCB annual<br />
business plan and several matters<br />
impacting on the building regulation<br />
reform agenda. BMF endorsed our 2010-<br />
11 business plan and were appraised<br />
of the considerable progress that has<br />
been made with the implementation of<br />
the National Construction Code reform,<br />
which incorporates on site plumbing<br />
requirements with the BCA.<br />
The Disability (Access to Premises –<br />
<strong>Building</strong>s) Standards are expected to<br />
be introduced on 1 May 2011. They will<br />
lead to significant improvements in the<br />
level of access required in new buildings<br />
and existing buildings undergoing<br />
renovation. It is also anticipated that<br />
corresponding changes will be included<br />
in BCA 2011 at the same time. The ABCB<br />
is partnering with the <strong>Australian</strong> Human<br />
Rights Commission to deliver awareness<br />
seminars to all capital cities in August<br />
and September 2010. The seminars will<br />
provide industry, disability groups and<br />
other interested stakeholders with an<br />
overview of the Premises Standards and<br />
their effect when implemented.<br />
I encourage you to attend the Premises<br />
Standards Seminar Series commencing<br />
in August. Further information on the<br />
Seminars can be found in this edition, or<br />
on our website at www.abcb.gov.au<br />

The <strong>Building</strong> Code of Australia (BCA)<br />
has, for some time, contained many<br />
provisions that need to be complied<br />
with by designers and installers<br />
including electricians and plumbers.<br />
Most of the earlier provisions have<br />
been in place for many years and<br />
so practitioners are aware of the<br />
requirements. However, since 2003,<br />
the BCA has contained new energy<br />
efficiency provisions relating to<br />
electrical and plumbing work. In<br />
addition some of these provisions<br />
changed in successive years with BCA<br />
2010 introducing major changes.<br />
The electrical and plumbing provisions<br />
are for both residential and commercial<br />
buildings and so are contained in both<br />
Volume One and Volume Two of the<br />
BCA.<br />
As the electrical and plumbing<br />
industries are more directly regulated<br />
by their own legislation, the ABCB<br />
saw a need for a Handbook to inform<br />
electricians and plumbers about the<br />
energy efficiency provisions of the BCA<br />
and how these provisions may affect<br />
them.<br />
Aspects of particular concern to<br />
electricians that the Handbook covers<br />
include-<br />
• The amount of insulation on a ceiling,<br />
usually over electrical wiring<br />
• Implication for insulation when<br />
installing downlights<br />
• Switching and controls for lighting,<br />
fans, garage exhaust systems, pumps,<br />
space heaters, swimming pool<br />
heaters, and boiling and chilling<br />
water appliances<br />
• The maximum power capacity of<br />
lights, fans, pumps and other airconditioning<br />
plant<br />
• Energy monitoring and metering<br />
facilities<br />
• Restrictions on the use of electric<br />
heaters<br />
• Specifications for a range of control<br />
gear<br />
Depending upon the scope for<br />
plumbers in the particular State or<br />
Territory, aspects of particular concern<br />
to plumbers that the Handbook covers<br />
include-<br />
• The insulation and installation of<br />
ductwork<br />
• The insulation and installation of<br />
heating water and cooling piping<br />
• The insulation and installation of<br />
supply hot water piping (through AS/<br />
NZS 3500)<br />
• The maximum power capacity of fans<br />
and pumps which has an impact on<br />
duct and pipe sizes<br />
• Restrictions on the use of electric<br />
supply water heaters and pool<br />
heaters<br />
• The use of solar heaters for domestic<br />
pools<br />
The Handbook is written in generic<br />
terms rather than specific clauses and<br />
so does not include all the requirements<br />
that may affect electricians and<br />
plumbers. It is also limited to those<br />
requirements that only address energy<br />
efficiency. The content of the Handbook<br />
addresses the national provisions of the<br />
BCA and does not include comments on<br />
individual State or Territory variations or<br />
additions.<br />
Other BCA requirements that may affect<br />
electricians and plumbers that are not<br />
covered in this Handbook, include-<br />
• Fire separation and construction<br />
of substations, conductors,<br />
switchboards and emergency<br />
equipment<br />
• Hearing augmentation systems and<br />
the location of lighting switches for<br />
people with disabilities<br />
• Fire fighting equipment including<br />
pumping systems, alarms, sprinkler<br />
systems, fire-control centres, fireservice<br />
controls, fire and smoke<br />
detection and warning systems,<br />
smoke exhaust systems, emergency<br />
lighting, exit and direction lighting<br />
and emergency warning and<br />
intercommunication systems<br />
• Lift installations<br />
• Artificial lighting for safe movement<br />
• Mechanical ventilation for health<br />
including Legionella control<br />
• Stormwater drainage<br />
• Provision of floor wastes<br />
• Construction of sanitary and other<br />
facilities<br />
• Water-proofing<br />
The Handbook is not intended to<br />
override or replace any legal rights,<br />
responsibilities or requirements or<br />
provide users with the specifics of the<br />
BCA. This Handbook is only intended to<br />
make users aware of provisions that may<br />
affect them, not exactly what is required<br />
by those provisions. If users determine<br />
that a provision may apply to them, the<br />
BCA should be read to determine the<br />
specifics of the provision.<br />
This Handbook, and another to assist<br />
designers and modellers with Section<br />
J Alternative Solutions, should be<br />
available later this year.<br />

NEW NATIONAL STANDARDS FOR PRIVATE BUSHFIRE SHELTERS<br />
From the Minister for Planning<br />
The new national performance standard<br />
for private bushfire shelters is now in<br />
effect in Victoria, Planning Minister<br />
Justin Madden announced in May of this<br />
year.<br />
Mr Madden said the Victorian<br />
Government had supported the<br />
recommendations from the 2009<br />
Victorian Bushfires Royal Commission<br />
Interim Report 2 Priorities for <strong>Building</strong><br />
in Bushfire Prone Areas that a national<br />
standard for private bushfire shelters be<br />
adopted by May 31 2010.<br />
“Private bushfire shelters cannot be<br />
guaranteed to save lives and the safest<br />
option is still to leave early,” Mr Madden<br />
said.<br />
“After the fires of February 7, 2009 our<br />
Government took action to establish<br />
an interim regulation and accreditation<br />
process for private bushfire shelters to<br />
provide clarity to Victorians ahead of the<br />
national standards.<br />
“Private bushfire shelters should only be<br />
considered as an option of last resort.<br />
People considering a private bushfire<br />
shelter should do so only as part or<br />
their overall bushfire management plan<br />
rather than the solution.”<br />
Mr Madden said the new national<br />
regulations replace interim regulations<br />
introduced in Victoria last year and<br />
amend the <strong>Building</strong> Regulations 2006<br />
to classify private bushfire shelters as<br />
a class 10c building under the BCA as<br />
applied in Victoria.<br />
“The <strong>Australian</strong> <strong>Building</strong> <strong>Codes</strong> <strong>Board</strong><br />
(ABCB) has now completed the national<br />
standard, which I understand is the first<br />
such standard in the world,” Mr Madden<br />
said.<br />
“Through the <strong>Building</strong> Commission,<br />
Victoria has been working closely with<br />
the ABCB on the development of the<br />
national standard to ensure a smooth<br />
transition from our current interim<br />
regulations for construction of private<br />
bushfire shelters.”<br />
Mr Madden said the national standard<br />
determined that private bushfire<br />
shelters were required to be a separate<br />
construction and no longer could be<br />
included as part of a building.<br />
“The national standard did consider<br />
the merits of bushfire shelters below or<br />
within a building but concluded the risks<br />
of these sorts of shelters in the event of<br />
a bushfire are too great,” he said.<br />
“This means private bushfire shelters<br />
must now be a separate building and<br />
not part of a dwelling.<br />
“A building permit for a private bushfire<br />
shelter will be required as well as from<br />
a fire safety engineer that the shelter<br />
complies with the requirements as<br />
set out in the national performance<br />
standard.”<br />
Victorian <strong>Building</strong> Commissioner and<br />
board member of the ABCB Tony Arnel<br />
said adoption of the national standard<br />
represented an important step for the<br />
Victorian community.<br />
“I am certain the building industry<br />
stands ready to meet the challenge of<br />
delivering private bushfire shelters that<br />
will provide greater protection from<br />
bushfires in the future,” Mr Arnel said.<br />
The national interim regulations will<br />
be in place for 12 months pending a<br />
decision by the ABCB to adopt them<br />
into the 2011 <strong>Building</strong> Code of Australia,<br />
which would be adopted nationally on<br />
May 1, 2011.<br />
A copy of the performance standard is<br />
available free of charge on the ABCB’s<br />
website at www.abcb.gov.au<br />

ABCB <strong>Board</strong> Member Perspective<br />
Interview with Robin Fardoulys, ABCB <strong>Board</strong> Member<br />
Background<br />
The make-up of the <strong>Australian</strong> <strong>Building</strong><br />
<strong>Codes</strong> <strong>Board</strong> includes a representative<br />
from all Federal, State and Territory<br />
Governments, together with five (5)<br />
building industry representatives,<br />
and one (1) Local Government<br />
representative. The position of chair<br />
is reserved for one of the industry<br />
representatives.<br />
Robin Fardoulys, Chairman of the<br />
<strong>Australian</strong> Construction Industry Forum<br />
(ACIF) is an industry representative who<br />
has recently been appointed to the<br />
<strong>Board</strong> and he provides an insight into<br />
his background, some of the industry–<br />
driven objectives within ACIF and his<br />
role as ABCB <strong>Board</strong> member.<br />
Robin Fardoulys<br />
I was born in Brisbane and educated at<br />
“Churchie” (Anglican Church Grammar<br />
School 1971-1977).<br />
My wife and I have three daughters and<br />
a son. My eldest daughter is a television<br />
journalist, the two other daughters are<br />
uni students and my son is at “Churchie”.<br />
My wife is a university science faculty<br />
lecturer.<br />
I joined my father’s construction<br />
business as a Construction Manager<br />
in 1981 after completing a Bachelor of<br />
Applied Science - Built Environment<br />
Degree and a Graduate Diploma in<br />
<strong>Building</strong> at the Queensland Institute of<br />
Technology (QIT).<br />
During my university holidays I worked<br />
on the sites labouring. It was a good<br />
income for a university student and<br />
it also exposed me to work methods,<br />
safety awareness processes, and just<br />
how physically hard trade work is.<br />
After graduating I undertook the<br />
construction of roadhouses for Mobil<br />
Oil in South East and South West<br />
Queensland. These were followed by<br />
roadhouses throughout Queensland for<br />
other Oil company brands including BP,<br />
Shell, Ampol and Caltex. Other projects<br />
included telephone exchanges, Defence<br />
Dept facilities at Amberley Air Force Base<br />
and Enoggera Army Base, Queensland<br />
State Government health, education<br />
and emergency services facilities,<br />
private sector schools, new works<br />
and refurbishments for the Hotel and<br />
Club industry, new Aged Care facilities<br />
and Child Care facilities as well as<br />
warehouses and commercial buildings.<br />
Since its commencement in 1976,<br />
Fardoulys Constructions has progressed<br />
into a prosperous and distinguished<br />
building and development practice.<br />
I believe that broad experience is<br />
important for everyone and I talk to my<br />
staff constantly about “growing” in their<br />
job and their personal development and<br />
career path, and involvement in industry<br />
groups is an important component of<br />
that growth.<br />
I have been fortunate to serve as the<br />
National President of the <strong>Australian</strong><br />
Institute of <strong>Building</strong>, a member of<br />
the Queensland Master Builder’s<br />
Association’s Contracts Committee and<br />
appointed an Adjunct Professor in the<br />
School of Urban Development – Faculty<br />
of Built Environment and Engineering<br />
at the Queensland University of<br />
Technology (QUT). My role as Chair<br />
of the ACIF and the appointment as<br />
Industry Representative to the ABCB<br />
is a pleasing aspect of service to the<br />
industry.<br />
ACIF was established to provide<br />
leadership and facilitate change within<br />
the industry, and to promote discussion<br />
on productivity, efficiency, research<br />
and innovation. Membership is by way<br />
of member Associations, ranging from<br />
the Property Council, and Electrical<br />
and Air Conditioning associations, to<br />
other subcontractor organisations<br />
such as Fire Protection and Precast<br />
Contractor associations, along with<br />
design profession organisations such<br />
as Architect, Engineer and <strong>Building</strong><br />
professional groups.<br />
As well as facilitating communication<br />
between the different interests that<br />
make up the construction sector, ACIF<br />
provides governments and other<br />
agencies with a central and efficient<br />
Robin Fardoulys<br />
industry liaison point. ACIF’s flagship<br />
Construction Forecasting Council<br />
produces the most reliable forecasts of<br />
activity in residential and non-residential<br />
building, and engineering construction,<br />
twice yearly.<br />
In my capacity as ACIF Chair, I am<br />
keen to react to the 2003 Cole Royal<br />
Commission findings that the <strong>Australian</strong><br />
building and construction industry<br />
was underachieving and considerable<br />
improvements in quality and efficiency<br />
should be made. ACIF and the APCC<br />
have identified five critical areas of<br />
performance which deserve monitoring<br />
and improvement – health and safety,<br />
productivity and competitiveness,<br />
economic security, skills and training,<br />
and environmental sustainability.<br />
Of these identified areas of focus, as a<br />
builder I am strong on initiatives that<br />
involve the securing of adequate skill<br />
resources. ACIF is currently seeking<br />
both government and industry<br />
financial assistance to initiate a Skills<br />
Forecasting Council as a component<br />
of ACIF’s workforce capability focus.<br />
Tomorrow’s trade and professional<br />
skill requirements need to be forecast,<br />
so the output and curriculum of trade<br />
8 • <strong>Australian</strong> <strong>Building</strong> Regulation Bulletin
colleges, and university design and<br />
building professions degree courses are<br />
compatible with the future demands.<br />
Construction education programs need<br />
meaningful industry input to meet<br />
present and future workforce demands,<br />
and this issue is of great interest to me.<br />
There is a common view that many of<br />
the future jobs or careers for our young<br />
people have not yet been invented or<br />
exist. This is probably very true for the<br />
construction industry, not so much<br />
because of what we build, but more so<br />
about how we build, and the materials<br />
and methods to be used.<br />
A recent report into construction<br />
education in Australia reported that<br />
the construction academic workforce<br />
is aging and not being replenished<br />
sufficiently. The university and<br />
construction sectors need to work<br />
together to encourage graduates with<br />
today’s skill sets to enter academia.<br />
The <strong>Australian</strong> Institute of<br />
<strong>Building</strong> has established<br />
a College of <strong>Building</strong><br />
to enable building<br />
professionals to “top up”<br />
their knowledge.<br />
Our future cities and<br />
communities will rely on<br />
technology to educate,<br />
design and drive economic<br />
and environmental<br />
initiatives such as metrics<br />
for building outputs, high<br />
energy efficiency designs<br />
and water conservation.<br />
Concepts such as Virtual<br />
Digital Modelling (also<br />
known as Digital Modelling<br />
or <strong>Building</strong> Information<br />
Modelling), which demands<br />
entire, complete and<br />
inter-related information<br />
management, will avoid<br />
inefficient and fragmented<br />
information gaps in<br />
documentation and design<br />
delivery, and will be more<br />
common in the near<br />
future. Clients, design team<br />
members and building<br />
contractors are joining as<br />
teams to deliver efficiency<br />
in design with an outcome<br />
of better time, cost and<br />
quality responses.<br />
Changes to concepts of project initiation<br />
and subsequent delivery are rapidly<br />
evolving. The challenge for the industry<br />
is to handle the mixture of finance, skills<br />
availability, urban design concepts,<br />
population growth, sustainability,<br />
affordability and regulatory<br />
requirements to deliver better outcomes<br />
for the industry, the community and the<br />
environment as a whole.<br />
My focus at the ABCB is not to<br />
necessarily influence technical matters,<br />
but to contribute to the practical<br />
implementation of the BCA. For<br />
example, the <strong>Board</strong> in recent times<br />
has done substantial work on bushfire<br />
shelters. I am a strong advocate for<br />
educating the general population who<br />
live in these bushfire-prone areas, as<br />
well as the industry practitioners who<br />
design, build or certify in those areas.<br />
The technical outcome as adopted<br />
needs to be a part of the knowledge and<br />
skill set of those living and working in<br />
those areas. As I mentioned earlier the<br />
skill and training of any <strong>Board</strong> initiative<br />
or update to the BCA has various<br />
avenues of adoption and understanding,<br />
and I believe that bushfire structure<br />
design or construction, is probably a<br />
whole new area of speciality, if not a<br />
whole new career path.<br />
The same is true of many or all of the<br />
numerous and constant changes to the<br />
BCA. The <strong>Board</strong> is educating the industry<br />
and it’s also up to the community and<br />
the industry participants to embrace<br />
the concept of change as brought on<br />
by the <strong>Board</strong>, and actively contribute<br />
towards its evolution in development,<br />
implementation and practice.<br />

The <strong>Building</strong> Commission was<br />
established in July 2009 to drive<br />
reforms associated with building<br />
related matters for the benefit<br />
of industry, consumers and the<br />
community.<br />
A Division of the Department of<br />
Commerce, it is made up of the Builder’s<br />
& Painter’s Registration <strong>Board</strong>s, the<br />
Plumber’s Licensing <strong>Board</strong> and the<br />
<strong>Building</strong> Industry Development<br />
directorate from the Department of<br />
Housing & Works. In combining these<br />
entities, the Government has generated<br />
efficiencies in the delivery of its services<br />
and will improve the framework industry<br />
operates within.<br />
The Commission runs a suite of reforms<br />
associated with building control,<br />
complaint resolution, practitioner<br />
registration and necessary auditing<br />
programs. It is to undertake an<br />
extensive implementation program of<br />
these reforms as its underlying role is<br />
to provide education and training for<br />
building related matters.<br />
The Commission provides information<br />
and advice to industry and the<br />
community on the development of<br />
building reforms, regulations, codes and<br />
standards.<br />
Reform of WA’s<br />
<strong>Building</strong> Laws<br />
Western Australia is in the final stages of<br />
drafting the most significant reforms to<br />
the laws governing the building industry<br />
in this State for over 7 decades. The<br />
reforms will:<br />
• streamline the building approval<br />
process by providing for private<br />
sector certification of compliance<br />
with building standards and to<br />
provide greater flexibility and<br />
certainty in the issue of building<br />
permits;<br />
• improve building standards through<br />
the mandatory inspection and<br />
certification of completed buildings;<br />
• replace the Builders’ Registration Act<br />
1939 and the Painters’ Registration<br />
Act 1961 with a modern and flexible<br />
scheme for regulating builders,<br />
painters and building surveyors;<br />
• introduce a new and improved<br />
dispute handling process with the<br />
<strong>Building</strong> Commission dealing with<br />
complaints at the front end and the<br />
State Administrative Tribunal dealing<br />
with intractable disputes, thereby<br />
abolishing the <strong>Building</strong> Disputes<br />
Tribunal;<br />
• provide for a new owner-builder<br />
approval process with improved<br />
controls;<br />
• create the position of <strong>Building</strong><br />
Commissioner as a statutory office<br />
holder within the Department<br />
of Commerce, with improved<br />
compliance powers; and<br />
• replace the Builders’ Registration<br />
<strong>Board</strong> and the Painters’ Registration<br />
<strong>Board</strong> with a <strong>Building</strong> Services <strong>Board</strong><br />
The Government intends to introduce<br />

COVER STORY<br />
Breaking through<br />
the barriers to<br />
urban density<br />
Romilly Madew<br />
Written by Romilly Madew, Chief Executive, Green <strong>Building</strong> Council of Australia<br />
Our cities are in transition. The<br />
frameworks of the past are no<br />
longer working and we are<br />
facing a future of environmental<br />
destruction, climate change,<br />
pollution, traffic gridlock,<br />
declining health, rising obesity<br />
and worsening standards of<br />
living.<br />
That’s the picture painted at the recent<br />
Built Environment Meets Parliament<br />
Summit (BEMP) in Canberra.<br />
KPMG’s Spotlight on <strong>Australian</strong> Cities<br />
report, released in conjunction with<br />
BEMP clearly pointed to federal and<br />
state planning systems that cannot<br />
cope. If that’s the case, how will they<br />
function with a population of 35 million?<br />
A selection of speakers was asked to<br />
provide their ‘breakthrough strategies’<br />
for a big Australia.<br />
And guess what?<br />
Their visions are<br />
overwhelmingly<br />
optimistic. The<br />
auditorium full<br />
of property and<br />
construction<br />
professionals,<br />
policy makers<br />
and politicians<br />
were clearly<br />
inspired by the<br />
possibilities for<br />
Australia’s future.<br />
It’s clear<br />
that we can<br />
address traffic<br />
congestion, rising<br />
greenhouse<br />
gas emissions, the obesity epidemic,<br />
social isolation and climate change by<br />
changing the way we live, work and play<br />
in our cities.<br />
Rather than lowering our standard of<br />
living, higher levels of urban density can<br />
deliver more liveable cities. What we<br />
must do is to take the community on the<br />
journey with us, and demonstrate clearly<br />
the benefits of urban density to both<br />
Australia’s natural environment and its<br />
people.<br />
Many people are already recognising<br />
the value of sustainable, higher density<br />
environments to their quality of life.<br />
Apartments are outselling houses in a<br />
number of <strong>Australian</strong> cities as demand<br />
for smaller and more affordable housing<br />
transforms the real-estate market. The<br />
West <strong>Australian</strong> reported last week that<br />
almost half the apartments at Australia’s<br />
first Green Star residential building, The<br />
Summer in South Fremantle, have been<br />
sold off the plan.<br />
“We had no idea just how significant<br />
sustainable living is to the lives of many<br />
people and we are definitely looking<br />
to increase the bar on all our future<br />
projects,” Lloyd Clark, the Managing<br />
Director of developer Match told The<br />
West <strong>Australian</strong>.<br />
While the future residents of Match<br />
won’t have access to the traditional<br />
quarter acre block, what they will have<br />
is open-plan apartments with large<br />
balconies, high ceilings, energy efficient<br />
appliances and good passive design<br />
features.<br />
That doesn’t mean that the Great<br />
<strong>Australian</strong> Dream of a house and land<br />
package is dead. But the BEMP Summit<br />
did foreshadow a future where there<br />
will be more choice for people who are<br />
prepared to forgo the garden and sell<br />
the car in exchange for a home closer<br />
to work, entertainment precincts and<br />
parks.<br />

Towards smarTer building<br />
Green stars all round as<br />
government takes up green<br />
building<br />
agenda<br />
After a slow start, all levels of<br />
government around Australia<br />
have taken up the green building<br />
agenda, a new study by the Green<br />
<strong>Building</strong> Council of Australia<br />
(GBCA) has found.<br />
The GBCA’s 2010 update to the Green<br />
Guide to Government Policy has found<br />
that all levels of government now<br />
have programs and policies to support<br />
sustainable building.<br />
“When we conducted our first<br />
comparative study of governments’<br />
policies on energy efficiency in<br />
buildings in 2007, many jurisdictions did<br />
not have comprehensive or cohesive<br />
policies,” says GBCA Chief Executive,<br />
Romilly Madew.<br />
“Indeed, we found that it was not<br />
uncommon for one agency to be<br />
unaware of another’s activities,<br />
despite the potential for collaboration<br />
to improve both the efficiency and<br />
effectiveness of both agencies’<br />
programs.<br />
“In the past two years, most jurisdictions<br />
have developed well-defined policies<br />
that guide whole-of-government<br />
strategies to encourage sustainable<br />
building, covering efficient use of<br />
energy, water and materials,” Ms Madew<br />
says.<br />
The <strong>Australian</strong> Government’s National<br />
Strategy on Energy Efficiency (NSEE),<br />
the first nationally consistent roadmap<br />
to reduce the carbon footprint of<br />
businesses and households across<br />
Australia, places a strong emphasis on<br />
the role of buildings in climate change<br />
mitigation.<br />
“State governments are also recognising<br />
the importance of strong leadership in<br />
the area of sustainable building, and<br />
have ‘put their houses in order’ in the<br />
last two years to demonstrate how to<br />
capture the benefits of sustainable<br />
buildings,” Ms Madew adds.<br />
Policy frameworks specific to green<br />
building include:<br />
• FEDERAL: Energy Efficiency in<br />
Government Operations (2006) aims<br />
to improve energy efficiency, and<br />
consequently reduce the whole of<br />
life cost and environmental impact<br />
of government operations, including<br />
the buildings it owns and leases.<br />
• NSW: The NSW Government<br />
Sustainability Policy (2008) commits<br />
to state government operations<br />
and activities being carbon-neutral<br />
by 2020. The policy includes statewide<br />
targets<br />
for government<br />
buildings:<br />
to return to<br />
greenhouse<br />
gas emissions<br />
from building<br />
energy use to<br />
2000 levels of 1.5<br />
million tonnes by<br />
2019-2020, with<br />
interim targets<br />
of 1.74 million<br />
tonnes by 2016-<br />
2017.<br />
• QLD: Cleaner Greener <strong>Building</strong>s lifts<br />
the environmental standards for all<br />
new homes, offices and government<br />
buildings in Queensland. Among the<br />
key requirements is electricity submetering<br />
in new office buildings and<br />
multi unit dwellings, giving tenants<br />
an incentive to reduce their power<br />
bills.<br />
• VIC: The Greener Government<br />
<strong>Building</strong>s Program allocates $60<br />
million to upgrade government<br />
office buildings, schools, hospitals<br />
and community buildings to reduce<br />
greenhouse gas emissions, energy<br />
costs and water use. By 2018,<br />
sites accounting for 90 per cent<br />
of the Government’s total energy<br />
consumption will undertake Greener<br />
Government <strong>Building</strong>s projects.<br />

investment across the Victorian<br />
economy.<br />

ADEQUACY AND RELIABILITY<br />
OF ALTERNATIVE STEEL<br />
Written by Thanabal Kaliannan, <strong>Building</strong> Engineering Division, <strong>Building</strong> and<br />
Construction Authority of Singapore<br />
Thanabal Kaliannan<br />
BACKGROUND<br />
Singapore’s building and construction<br />
industry has witnessed a huge surge<br />
in demand since 2006. However, a<br />
shortage of manpower, coupled with<br />
an overdependence on sand and<br />
granite for concrete construction has<br />
signalled an urgent need to enhance the<br />
sustainability of this industry. Promoting<br />
steel construction has been one key<br />
measure to cope with this.<br />
Steel construction’s potential of offering<br />
fast-track solutions for early return of<br />
capital investments and significantly<br />
reducing the manpower requirement<br />
has long been recognized. However, it<br />
has failed to gain widespread popularity<br />
locally and it is often used only where<br />
there are no viable alternatives such<br />
as long-span roof and super high-rise<br />
building frame construction. There<br />
may be a number of reasons for this.<br />
From the material point of view, there<br />
are issues involving cost and quality as<br />
well as technical ones. There seems to<br />
be a longstanding trade-off between<br />
cost and quality – steel materials<br />
manufactured in more developed<br />
Western countries are notorious for their<br />
price while those from the developing<br />
countries within this region, on the other<br />
hand, are often reportedly for a lack of<br />
proper production control and quality<br />
assurance. From a technical perspective,<br />
the BS5950 design code only provides<br />
guidance and design parameters for<br />
steel materials manufactured to their<br />
national standards, in this case, it would<br />
be the British Standards (BS or BS EN)<br />
and this has seriously narrowed down<br />
the choices of steel materials which can<br />
be sourced from the region.<br />
To address some of these issues<br />
and to promote wider use of steel<br />
in construction, the <strong>Building</strong> and<br />
Construction Authority (BCA) of<br />
Singapore released a new design guide,<br />
BC1: 2008 in April 2008 on the use of<br />
alternative steel materials to design<br />
building structural steelworks to BS5950<br />
in Singapore. The use of alternative<br />
steel materials, other than BS and BS<br />
EN is now permitted; offering more<br />
material sourcing options in the hope<br />
that this will achieve greater economy<br />
and affordability. However, in opening<br />
up the sources and allowing different<br />
steel grades which are manufactured to<br />
a wide variety of material standards to<br />
be used, it is also important that quality<br />
and safety are not compromised. In this<br />
connection, it is imperative for BCA to<br />
put in place proper design requirements<br />
and framework within BC1 to ensure<br />
that the alternative steel that are used<br />
in the industry is adequate and reliable<br />
for various structural applications. It is<br />
also an opportunity to impose uniform<br />
requirements and provide a level<br />
playing field for all steel, regardless<br />
of where it comes from and including<br />
those manufactured to the BS or BS EN<br />
material standards.<br />
Essentially, BC1 provides a design<br />
framework to guide engineers and<br />
designers to classify steel materials into<br />
three different classes. This classification<br />
approach comprises mainly the<br />
adequacy and reliability assessments.<br />
Consequently, by classifying the steel,<br />
it will determine whether or not the<br />
materials concerned are fit for design to<br />
BS5950, with or without restriction and<br />
accordingly, appropriate prescriptive<br />
design recommendations and values are<br />
given.<br />
ADEQUACY OF STEEL MATERIALS<br />
The two major concerns over the use<br />
of steel materials are their adequacy<br />
and reliability. Adequacy refers to the<br />
ability of steel materials to meet the<br />
material performance requirements<br />
which are the essential requirements<br />
for the mechanical, physical, chemical,<br />
dimensional tolerances and/or other<br />
relevant properties of steel materials. In<br />
BC1, the material performance indicators<br />
are derived, with reasonable and<br />
appropriate adjustments, based on the<br />
relevant clauses given in several parts of<br />
BS5950.<br />
In reality, the need to impose<br />
requirements on mechanical properties<br />
such as yield strength, tensile strength,<br />
ductility and toughness on the steel<br />
requires little explanation as these are<br />
the obvious performance indicators<br />
from the structural perspectives.<br />
However it is worth mentioning<br />
that BC1 has also listed additional<br />
requirements on carbon content,<br />
carbon equivalent value (CEV), impact<br />
value, impurities level (sulphur and<br />
phosphorus), manufacturing process<br />
and manufacturing tolerances to ensure<br />
optimal structural performance. Carbon<br />
equivalent value (CEV) is an empirical<br />
measure of hardening tendency<br />
of heat-affected zone (HAZ) which<br />
promotes crack formation. It is also a<br />
significant indicator of the weldability<br />
of steel products. Since steelmaking<br />
is based on recycling of scrapped<br />
steel over many times, the level of<br />
non-metallic impurities, especially<br />
sulphur and phosphorous, need to<br />
be observed as they are the source of<br />
brittleness in structural steel which<br />
may lead to lamellar tearing and low<br />

formability. Metallurgical behaviour and<br />
performance of steel materials are also<br />
highly dependent on the manufacturing<br />
process like de-oxidation method,<br />
and quenching and tempering. For<br />
instance, rimming steel associated with<br />
internal voids shall not be allowed for<br />
structural use whereas application of<br />
quenched and tempered steel with low<br />
ductility and formability shall only be<br />
restricted to steel plates and hot rolled<br />
sections. Lastly, deviations from nominal<br />
dimensions and mass shall be well<br />
within the manufacturing tolerances<br />
to assure member resistance and<br />
structural safety, and constructability.<br />
Manufacturing tolerances are therefore<br />
important to prevent manufacturers<br />
from under-sizing and taking advantage<br />
of the liberal requirements.<br />
Due to differences in technical<br />
requirements ranging from<br />
manufacturing process to structural<br />
performance, BC1 has to adopt a more<br />
realistic and reasonable approach to<br />
make these requirements materialspecific.<br />
Different sets of requirements<br />
are imposed on each of the nine<br />
different categories of steel materials,<br />
namely steel plates, hot rolled sections,<br />
hollow sections, steel for cold forming,<br />
non-preloaded bolting assemblies,<br />
preloaded bolting assemblies, welding<br />
Integrated Resort at Marina Bay - roof top skypark with 60m cantilever<br />
consumables, profiled steel sheets<br />
and stud shear connectors, which are<br />
commonly used in the construction<br />
industry.<br />
RELIABILITY OF STEEL MATERIALS<br />
Another critical aspect is the reliability<br />
of steel materials which is the ability<br />
to meet the quality assurance<br />
requirements; for steel manufacturers<br />
to provide adequate assurance to<br />
ensure the compliance of the actual<br />
performance of their products with the<br />
nominal specifications stipulated.<br />
The utmost importance of material<br />
reliability is understandable as the<br />
so-called ‘adequate’ materials are<br />
theoretically sound on paper only<br />
and their ability to perform up to their<br />
nominal specifications in reality needs<br />
some form of guarantee or assurance,<br />
if not justification. In view of this, BC1<br />
requires manufacturers, as a minimum,<br />
to establish an approved factory<br />
production control (FPC) system and to<br />
provide assurance to their products in<br />
the form of authenticated manufacturer<br />
or mill test certificates (MTC). The core<br />
objective this requirement is driven by a<br />
desire to use only ‘quality products from<br />
quality mills’ in Singapore’s building and<br />
construction industry.<br />
In fact, it is indisputable that only<br />
‘quality mills’ are able to produce<br />
‘quality products’. A thorough factory<br />
production control system is a<br />
necessary evidence to substantiate the<br />
status of ‘quality mills’. According to<br />
BC1, manufacturers of steel materials<br />
must maintain an FPC system which<br />
consists of quality procedures, written<br />
instructions, regular inspection<br />
and test plans to control feedstock<br />
materials, equipment, personnel and<br />
production process which can affect<br />
product quality in anyway. Therefore,<br />
proper documentation of feedstock<br />
materials, inspection, calibration and<br />
maintenance history of equipment,<br />
personnel background and qualification,<br />
organisational charts defining<br />
responsibility of individual personnel<br />
and their inter-relationship, results of<br />
product testing, as well as procedures<br />
on product marking and nonconforming<br />
products, are required to<br />
facilitate audit and attestation by thirdparty<br />
accredited certification agencies.<br />
To attain the ‘quality mills’ status under<br />
the BC1 framework, manufacturers<br />
need to have their FPC system ‘audited’<br />
and attested by an independent thirdparty<br />
accredited certification agency<br />
acceptable to or recognized by BCA<br />
– for instance, Bureau Veritas, TUV<br />
Rheinland, Det Norske Veritas, Lloyd’s<br />
Register, Germanischer Lloyd, etc. A FPC<br />
certificate from one of these agencies,<br />
on the basis of initial inspection as<br />
well as continuous surveillance and<br />
assessment through annual inspection,<br />
shall form the acceptable indicator for<br />
an attested FPC system.<br />
It shall also be noted that compliance<br />
with ISO9001 is merely complimentary<br />
but insufficient to justify the reliability of<br />

Manufacturer Test Certificate<br />
As an additional layer of guarantee<br />
and assurance of quality in their steel<br />
products, audited mills should issue<br />
authenticated test certificates to<br />
substantiate the compliance of every<br />
batch of products delivered with their<br />
nominal specifications. Such certificates<br />
are not only evidences of product<br />
conformity, but more importantly, they<br />
are also useful tools to provide sufficient<br />
information for qualified persons (QPs)<br />
to assess and control steel materials<br />
during fabrication, and to help the QPs<br />
or their site representatives to decide<br />
whether it is necessary to carry out<br />
further material checks on the batch of<br />
steel being delivered.<br />
Generally, two types of testing should<br />
be conducted by the manufacturer<br />
– firstly, routine testing which is<br />
carried out in accordance with the<br />
manufacturer’s written procedures;<br />
and secondly, specific testing which is<br />
carried out upon request of purchasers<br />
at the time of order. To certify such<br />
testing, the manufacturer shall<br />
provide an authenticated certificate<br />
of compliance. The documents shall<br />
also be validated by, if necessary, third<br />
party inspection agency authorised by<br />
the purchaser or BCA. An acceptable<br />
manufacturer test certificate (MTC) shall<br />
be authenticated by the manufacturer’s<br />
company stamp, and shall contain<br />
information of the manufacturer,<br />
reference details, material specifications,<br />
information for traceability, as well as<br />
test results.<br />
materials and not the finished products<br />
are permitted in the MTC by BC1, it<br />
should be clearly indicated in the<br />
certificate so that there is no confusion.<br />
DESIGN IMPLEMENTATION<br />
BC1 provides guidance for engineers<br />
to follow during the design stage. The<br />
design procedure is essentially based<br />
on the classification approach which<br />
consists of both adequacy assessment<br />
and reliability assessment of the steel<br />
materials to be used in design to BS5950,<br />
and eventually to categorise these<br />
materials into three categories, from<br />
superior to inferior – Class 1, Class 2 and<br />
Class 3.<br />
Adequacy Assessment<br />
The first step in the classification<br />
approach involves the adequacy<br />
assessment, i.e. verification of material<br />
adequacy against the material<br />
performance requirements. Adequacy<br />
assessment is only meant to evaluate the<br />
adequacy of steel materials of particular<br />
specifications and its result is therefore<br />
independent of the source of materials.<br />
Two possible modes of adequacy<br />
assessment are certification and material<br />
testing.<br />
Certification is the rigorous evaluation<br />
of the specifications of steel materials<br />
commonly available in Singapore<br />
– namely British/European (BS/EN),<br />
American (ASTM/API/AWS), Japanese<br />
(JIS), <strong>Australian</strong>/New Zealand (AS/NZS)<br />
and Chinese (GB) steel materials, against<br />
the essential material performance<br />
requirements of BC1. A list of certified<br />
steel materials which only contains steel<br />
materials complying with the relevant<br />
material performance requirements,<br />
has been derived for the convenience of<br />
the design engineers. Most commonly<br />
available materials in Singapore are BS/<br />
EN, ASTM/API/AWS, JIS, AS/NZS and<br />
GB steel materials are adequate and<br />
therefore included in this list. Use of any<br />
steel material from this certified list is<br />
considered having met and passed the<br />
adequacy assessment.<br />
Material testing, on the other hand,<br />
is the process of demonstrating<br />
the adequacy of non-certified steel<br />
materials outside BS/EN, ASTM/API/<br />
AWS, JIS, AS/NZS and GB steel materials<br />
such as the use of Indian, Korean or<br />
Russian steel during the design stage<br />
through appropriate sample testing<br />
and test method. Such testing for the<br />
purpose of adequacy assessment during<br />
the design stage shall not exempt<br />
the purchasers from performing the<br />
obligatory inspection and testing<br />
in accordance with appropriate<br />
regulations during contract execution<br />
stage. To prove the compliance of such<br />
materials with all the relevant material<br />
performance requirements, test reports<br />
from accredited laboratory under the<br />
Singapore Accreditation Council’s<br />
Singapore Laboratory Accreditation<br />
INTERNATIONAL REGULARTORY DEVELOPMENT<br />
In Singapore, steel materials for building<br />
construction are mostly supplied by<br />
stockholders and traders, unless the<br />
projects are very sizeable and there<br />
is magnitude of scale and financial<br />
benefits to purchase directly from the<br />
steel mills. Under such circumstance,<br />
a validated copy of the authenticated<br />
MTC shall be given to the end purchaser<br />
by the stockholder. To prevent any<br />
fraud and tempering of the MTC, exact<br />
quantity, batch and heat number of<br />
the steel materials delivered to the end<br />
purchaser, together with the purchase<br />
and delivery orders should be clearly<br />
indicated in the MTC. Finally, although<br />
mechanical test results and chemical<br />
analysis based on the feedstock<br />

INTERNATIONAL Regulatory Development<br />
Scheme (SINGLAS) or other laboratory<br />
accredited under a mutual recognition<br />
agreement with SINGLAS are required.<br />
Reliability Assessment<br />
The second step in the classification<br />
approach involves the reliability<br />
assessment, i.e. verification of material<br />
reliability against the quality assurance<br />
requirements. Reliability assessment<br />
to ensure the steel materials are<br />
manufactured under stringent quality<br />
assurance system shall meet the quality<br />
assurance requirements. Failure in the<br />
reliability assessment shall result in the<br />
downgrading of material class to Class<br />
3. A complete reliability assessment<br />
consists of two compulsory evaluation<br />
processes, namely FPC certification and<br />
manufacturer test certification.<br />
Manufacturers of steel materials shall<br />
have an FPC system already attested by<br />
an independent third-party certification<br />
agency acceptable to or recognised by<br />
BCA. Valid FPC certificates issued by the<br />
certification agency upon successful<br />
first and annual inspections shall be<br />
produced by the manufacturers as an<br />
indicator of an FPC system acceptable<br />
to BCA. In FPC certification, QPs shall<br />
evaluate the validated copy of the valid<br />
FPC certificate, obtained either directly<br />
from the manufacturer or through the<br />
stockholder or trader. The document<br />
mentioned shall also be made<br />
available for subsequent inspection<br />
by BCA, if required. It shall be pointed<br />
out that ISO9001 certificate is only<br />
complimentary, while European Union<br />
FPC certificates and API Monograms can<br />
be considered ‘acceptable in lieu’.<br />
Manufacturers shall issue an<br />
authenticated test certificate for every<br />
batch of steel materials delivered as a<br />
form of quality assurance on the steel<br />
materials. Actual quantity of steel<br />
materials delivered shall be clearly<br />
indicated by the stockholders. In<br />
manufacturer test certification, QPs<br />
shall inspect and confirm that all the<br />
mandatory information is indicated on<br />
the actual certificate. The document<br />
shall also be made available for<br />
inspection by BCA, if required.<br />
Classification of Steel Materials<br />
The classification procedure will end<br />
with the class of steel materials being<br />
determined. Three classes, namely Class<br />
1, Class 2 and Class 3, are the possible<br />
outcome. Class 1 status can only be<br />
achieved by certified steel materials,<br />
i.e. those materials which meet<br />
material performance requirements<br />
through rigorous certification process,<br />
if and only if quality assurance given<br />
by the manufacturers also satisfies<br />
the respective requirements. These<br />
materials can be used as per normal<br />
to BS5950. No material factor will be<br />
applied on the design strength of<br />
the steel. In other words, full nominal<br />
strength given by the material standard<br />
of Class 1 structural steel is employed<br />
for design calculation. On the other<br />
hand, design parameters for bolts and<br />
welds are those recommended by the<br />
respective national standards.<br />
Similarly, non-certified steel materials<br />
outside BS/EN, ASTM/API/AWS, JIS,<br />
AS/NZS and GB steel materials which<br />
are proven to be reliable can also be<br />
used as per normal to BS5950, if they<br />
can demonstrate compliance with<br />
the essential material performance<br />
requirements through material testing.<br />
These materials are considered as Class<br />
2 materials under the classification<br />
framework of BC1. However, a lack of<br />
local experience and rigorous study,<br />
and hence understanding on the local<br />
use of such materials necessitates a<br />
material factor of 1.1 to be imposed on<br />
Arts and Science Museum at Marina Bay Integrated Resorts under construction<br />
the design strength of Class 2 structural<br />
steel. Likewise, Class 2 connection<br />
components like bolts, welds and stud<br />
shear connectors, shall be designed to<br />
lower strength parameters as compared<br />
to their Class 1 counterparts.<br />
All other steel materials which fall<br />
outside Class 1 and Class 2 are regarded<br />
as Class 3 materials which fail to satisfy<br />
material performance requirements<br />
and/or quality assurance requirements.<br />
This type of materials which are really<br />
‘commercial-grade’ steel shall be<br />
restricted to non-structural use only. The<br />
design strength for Class 3 steel shall be<br />
limited to not more than 170 N/mm2.<br />
However, use of Class 3 bolts, welds and<br />
stud shear connectors to BS5950 is not<br />
permitted.<br />
SPECIAL CASE<br />
While BC1 is in the early phase of<br />
implementation, interim measures<br />
are necessary to ensure a smoother<br />
transition for key industry players<br />
to adjust and switch to the new<br />
requirements, as well as to cater for<br />
existing on-going projects and current<br />
stockpiles of steel materials which meet<br />
adequacy requirements but obviously<br />
do not come with FPC certificates from<br />
audited mills. For the above reasons, a<br />
material performance-based assessment<br />
in lieu of the adequacy and reliability<br />
18 • <strong>Australian</strong> <strong>Building</strong> Regulation Bulletin
assessments, based on material testing<br />
per heat or batch and control might<br />
be appropriate under the alternative<br />
route provided for under Clause 4.4 of<br />
BC1. Subject to case-by-case approval<br />
from BCA, the steel materials concerned<br />
may be treated as Class 2 materials if<br />
their adequacy and reliability can be<br />
guaranteed through testing and control<br />
plans of the materials delivery to site.<br />
As this special provision is meant to<br />
be an interim measure to cope with<br />
the transition stage, it should not be<br />
seen as an escape route to by-pass<br />
the new requirements for quality<br />
requirements. QPs who resort to using<br />
this alternative path because of material<br />
non-compliance with quality assurance<br />
requirements, not only have to monitor<br />
and propose a very rigorous material<br />
control plan, but also have to review<br />
and redo the design because of the<br />
change in the material classification. In<br />
addition, QPs will still have to continue<br />
to shoulder the quality problem caused<br />
by lesser manufacturers.<br />
USE OF ALTERNATIVE<br />
STEEL MATERIALS<br />
The main objective of introducing these<br />
new requirements on both adequacy<br />
and reliability of the steel materials is to<br />
improve the resilience and sustainability<br />
of Singapore’s steel construction<br />
industry. The enforcement and full<br />
implementation of such requirements<br />
will bring about some tangible and<br />
positive improvements in the long run<br />
as few will argue on the need for quality.<br />
In the short term, some re-adjustments<br />
will be necessary amongst all the key<br />
industry stakeholders while some will<br />
be affected more and others will view<br />
the new requirements as restrictive.<br />
The long term objective should not be<br />
clouded by the short term difficulties<br />
which are usually driven by commercial<br />
consideration. Such issues are best<br />
addressed separately.<br />
In the local context, the need to<br />
look into the use of alternative steel<br />
materials is also understandable from<br />
the availability point of view. The<br />
presence of Chinese steel materials<br />
in this region is a case in point. Under<br />
the new provision of BC1, as long as<br />
the steel materials can be proven to<br />
be adequate and reliable, their use to<br />
BS5950 will be allowed irrespective<br />
of where the materials originate from<br />
and what production standards they<br />
are manufactured to. By widening the<br />
option to source these materials from,<br />
it is hoped that more economical and<br />
sustainable steel construction will<br />
eventually result in Singapore.<br />
Equal Platform for all<br />
Steel Materials<br />
The mandatory requirement on material<br />
adequacy and reliability implies that<br />
only adequate and reliable materials<br />
can be used under the provision of BC1.<br />
Therefore, the approach is consistent<br />
and fair, and all steel materials,<br />
including those manufactured to BS<br />
and BS EN standards are treated equally<br />
without any preference when design<br />
recommendations are given. In addition,<br />
BC1 is fair to all Class 1 steel materials<br />
by allowing the use of the full material<br />
strength as its design strength. Design<br />
strengths recommended by their<br />
respective national steel design codes<br />
might not be appropriate because of<br />
the fundamental difference in design<br />
philosophy compared to BS5950.<br />
Quality Culture<br />
BC1 took the opportunity to address the<br />
long-standing material problems where<br />
non-certified materials which are readily<br />
available have been used in the past and<br />
are still being used today. The notion<br />
that material adequacy and reliability<br />
can be assured by testing a few tensile<br />
coupons is a fallacy which really needs<br />
to be debunked. Material production<br />
standards are serious documents<br />
with complicated processes in which<br />
manufacturers have to follow through<br />
strictly. There are in-line production<br />
tests in place which would not be<br />
possible to duplicate off-line once the<br />
material is produced. The manufacturer<br />
test certificates are only meaningful if<br />
manufacturers adhere to and follow the<br />
production standards closely and report<br />
the information faithfully. The mere<br />
existence of a certificate is not sufficient<br />
proof because such information<br />
can be easily copied over from the<br />
feedstock materials without having to<br />
do a single production test. The need<br />
for consistently reliable and quality<br />
materials, and to single out, reward and<br />
encourage manufacturers who practiced<br />
quality assurance and took the trouble<br />
to put in place a stringent production<br />
control system and product certification<br />
is clear. With such a framework in<br />
place, the manufacturers will be more<br />
responsible and forthcoming. Moving<br />
forward, the Authority will be more<br />
vigilant on the use of non-certified<br />
materials such as JIS G3101 SS400, ASTM<br />
A500 and BS4360 Grade 43A which are<br />
still readily available. Key stakeholders<br />
(traders, stockholders, fabricators<br />
and QPs) should well take note of this<br />
development.<br />
CONCLUSIONS<br />
Adequacy and reliability of steel<br />
materials are the two major concerns<br />
in promoting alternative use of steel<br />
materials to pave a way towards a more<br />
sustainable construction industry in<br />
Singapore. With BC1 in place, adequacy<br />
and reliability of all steel materials<br />
are checked against the material<br />
performance and quality assurance<br />
requirements. Their adequacy can be<br />
evaluated through either certification or<br />
material testing; whereas their reliability<br />
must be substantiated by factory<br />
production control (FPC) certificate<br />
and mill test certificate (MTC) from the<br />
manufacturers. The steel materials are<br />
categorised into three classes, each with<br />
different scope for use with and without<br />
restriction, in design to BS5950.<br />
BC1 will bring several positive benefits<br />
to the steel construction industry in<br />
the long run. In the short term, it is<br />
recognised that some re-adjustments<br />
will be necessary and some stakeholders<br />
will be affected more than others. The<br />
use of alternative steel will open up<br />
the availability and widen the source<br />
of materials which will result in greater<br />
economy and affordability. All steel<br />
materials, including BS and BS EN<br />
materials, regardless of country of origin,<br />
are treated equally in the same manner.<br />
Finally, BC1 addresses some quality<br />
issues head-on in the hope it will lead to<br />
a healthy quality culture on steel usage<br />
which will set a new standard for others<br />
in the region to follow.<br />

INTERNATIONAL Regulatory Development<br />
Toward shock-proof<br />
infrastructure<br />
Written by the National Research Council Canada<br />
The devastation caused by recent<br />
earthquakes in Haiti and Chile, as well<br />
as by terrorist activities around the<br />
world, underscores the need for better<br />
construction materials and designs to<br />
protect critical public infrastructure<br />
against such extreme shocks.<br />
Canada’s core public infrastructure<br />
includes transport systems (roads,<br />
bridges and transit), public buildings<br />
that provide essential services,<br />
and municipal systems that deliver<br />
potable water and remove wastes. The<br />
foundation of our public infrastructure<br />
is a common building material: concrete.<br />
“Traditionally, we’ve designed our<br />
infrastructure to withstand natural<br />
disasters, not man-made events,” says<br />
Dr. Zoubir Lounis, leader of the concrete<br />
structures group at the NRC Institute for<br />
Research in Construction (NRC-IRC) in<br />
Ottawa.<br />
In collaboration with the University<br />
of Ottawa, NRC is combining high<br />
performance concrete and advanced<br />
composite materials — consisting of<br />
fibre-reinforced polymers — to help<br />
make critical structures<br />
more shock-resistant.<br />
By adding a shock<br />
absorber, the new<br />
construction materials<br />
could improve the<br />
safety of critical<br />
infrastructure in<br />
Canada and around the<br />
world.<br />
“Since it would be<br />
too expensive to<br />
protect all our public<br />
infrastructure, we’re<br />
developing new<br />
technology as well<br />
as a risk management approach,” says<br />
Dr. Lounis. This approach involves<br />
identifying public infrastructure that is<br />
critical both from a public safety and an<br />
economic standpoint. The goal would<br />
then be to incorporate shock-resistant<br />
materials into key structures at critical<br />
stress points — such as the load-bearing<br />
columns holding up a highway overpass<br />
— in order to provide adequate strength<br />
and safety margins, and extend their<br />
service life.<br />

Did you<br />
know?<br />
Concrete structures testing facility at NRC Institute for Research in Construction.<br />
Statistics Canada<br />
has estimated the<br />
value of Canada’s<br />
core public<br />
infrastructure<br />
— including<br />
roads, bridges,<br />
drinking water,<br />
waste water and<br />
sewage treatment<br />
systems — at<br />
more than $286<br />
billion.<br />
The state of our roads, bridges, buildings<br />
and water/waste water systems is closely<br />
linked to our economy, safety and<br />
security, and quality of life. Consider the<br />
potential impact of disrupting traffic<br />
across an important trade route like the<br />
Ambassador Bridge, which links Windsor<br />
and Detroit, for even one day.<br />
“The idea is not so much to protect<br />
these structures but to enhance public<br />
safety by ensuring that if an accidental<br />
or intentional shock does occur, the<br />
structure doesn’t crumble but is<br />
only damaged — in other words, a<br />
‘controlled and more ductile’ failure,”<br />
says Dr. Husham Almansour, the NRC<br />
project leader. “Our goal is to give<br />
people enough time to evacuate —<br />
depending on the size of the shock and<br />
the importance of the infrastructure.”<br />
“When we design a retrofit to resist<br />
extreme shocks, we want to make the<br />
structure more robust,” adds Dr. Lounis.<br />
“Robustness means the structure has<br />
built-in redundancies, so external<br />
stresses are distributed between the<br />
different load-bearing elements and any<br />
damage that results is proportional to<br />
the shock or load.”<br />
20 • <strong>Australian</strong> <strong>Building</strong> Regulation Bulletin
NRC’s new building materials and<br />
systems will undergo thorough<br />
testing that simulates the effects of<br />
blast or heavy impacts. “This is a huge<br />
undertaking with many private and<br />
public partners,” says Dr. Lounis. After<br />
the shock-resistant materials and<br />
systems have been fully evaluated, they<br />
will be made available to Canadian<br />
companies and public infrastructure<br />
owners, giving them a competitive edge<br />
in world markets.<br />
Toward a hundred<br />
year bridge<br />
Much of Canada’s public infrastructure<br />
was built after the Second World War<br />
and is now approaching the end of its<br />
design life. “Instead of using the same<br />
conventional materials and doing the<br />
usual repairs, we’re thinking about how<br />
to replace existing structures with new<br />
structures that will last twice as long,”<br />
says Dr. Zoubir Lounis.<br />
For example, most current bridges were<br />
meant to have a design life of about fifty<br />
years. High and ultra-high performance<br />
concrete (UHPC) could double their life<br />
span because it contains steel fibres and<br />
more cementing materials than normal<br />
concrete. “It is also more resistant to<br />
corrosive agents,” says Dr. Lounis. “It will<br />
take up to 70-80 years for salt and water<br />
to reach the steel and corrosion to start,<br />
whereas with normal concrete, the salt<br />
could reach the steel after 15 years.”<br />
INTERNATIONAL REGULARTORY DEVELOPMENT<br />
“UHPC can be three, four or five times<br />
more expensive than normal concrete,”<br />
he adds. “But the entire life-cycle<br />
costs of a bridge made with UHPC<br />
will be much lower. Over a hundred<br />
years, the bridge will require very little<br />
maintenance, so you won’t need to<br />
close it as often to repair or replace a<br />
component.”<br />

An 18-month independent study<br />
has concluded that in many areas<br />
of Australia typical <strong>Australian</strong><br />
homes can achieve an increase of<br />
2-2.5 stars of energy efficiency by<br />
simply changing from the worstperforming<br />
windows to the bestperforming<br />
windows.<br />
The study, conducted by the Sustainable<br />
Windows Alliance (SWA), follows lengthy<br />
and in-depth research into the impact<br />
windows have on residential energy<br />
efficiency. Launched mid-2008, the<br />
SWA is a joint initiative of the <strong>Australian</strong><br />
Glass and Glazing Association and the<br />
<strong>Australian</strong> Window Association, working<br />
in partnership with Sustainability<br />
Victoria.<br />
The project was initiated to investigate<br />
the economic and scientific basis for<br />
high performance windows. Now, the<br />
industry, armed with these facts, aims<br />
to raise community awareness, both<br />
within the building industry and the<br />
general public. The SWA hopes to create<br />
more informed end-consumers, able to<br />
make more considered decisions about<br />
the construction or renovation of their<br />
homes, supported by a local industry<br />
capable of serving their needs.<br />
The technical study was conducted by<br />
building physicist and energy expert<br />
Dr Peter Lyons using a methodology<br />
developed and agreed by a panel of<br />
leading buildings scientists within<br />
Australia and from abroad. The results<br />
provide the first collaborative resource<br />
of its kind and clearly demonstrate the<br />
impact of glazing and framing options<br />
on building energy<br />
efficiency across a range<br />
of house designs and<br />
climate zones throughout<br />
Australia.<br />
“Currently there is a very<br />
low level of awareness<br />
of the role windows and<br />
glass play in building<br />
energy efficiency. That<br />
knowledge which does<br />
exist in the building<br />
industry and broader<br />
community often<br />
ranges from inconsistent<br />
to outright misleading,<br />
but this study provides a common<br />
reference point to assist architects,<br />
builders, and consumers alike to make<br />
better-informed decisions on the most<br />
appropriate window for their needs,”<br />
says Lachlan Austin from the SWA<br />
steering committee.<br />
KEY FINDINGS FROM ThE STUDY<br />
• Moving from the worst-performing<br />
windows to the best performing<br />
windows can give a home an<br />
AccuRate star increase of 2-2.5 stars;<br />
• Applying passive solar design<br />
principles can provide further<br />
improvement by up to 1 star; and<br />
• Different locations within Australia<br />
require different glazing solutions,<br />
and within that, even different<br />
orientations of the building benefit<br />
from different window solutions.<br />
Nigel Carpenter, Executive Director<br />
of the AGGA, says the study clearly<br />
shows that better performing<br />
windows significantly reduce energy<br />
Photo provided by G. James<br />
consumption for home-owners, and<br />
therefore provides the opportunity for<br />
substantial savings on the household<br />
budget, and reduction in household<br />
carbon footprint. Windows have a<br />
long lifespan, working 24 hours a day,<br />
year in year out, without the need for<br />
any great human intervention. As an<br />
investment for the comfort and value<br />
of a home, they should rate far ahead<br />
of some discretionary spends beloved<br />
by consumers such as benchtops, and<br />
door handles. Nigel proposes, “Viewed<br />
against improved windows, these<br />
are dead assets, which serve only to<br />
date depreciate in value. In contrast,<br />
windows should be better categorised<br />
as investments in occupant comfort,<br />
operating cost reduction and a higher<br />
property value at resale”.<br />

INDUSTRY Perspective<br />
INDUSTRY DISCIPLINE FOR<br />
SOFTWARE SIMULATION<br />
Interview with Phil Wilkinson, CEO, <strong>Australian</strong> Institute of Refrigeration,<br />
Air Conditioning and Heating<br />
Phil Wilkinson<br />
Q: How important is the use of energy<br />
analysis software in demonstrating a<br />
building’s compliance with Section J<br />
of the <strong>Building</strong> Code of Australia?<br />
PW: In short, the use of energyanalysis<br />
software in performancebased<br />
solutions is very important in<br />
demonstrating a building’s compliance.<br />
And the best way to show that<br />
compliance with the Code is being<br />
achieved is by meeting targeted annual<br />
energy use.<br />
This requires the use of modelling with<br />
sophisticated software that calculates<br />
the annual energy consumption hourby-hour<br />
and system-by-system.<br />
The use of BCA verification method JV3<br />
allows engineers and designers to be<br />
flexible in their approach to achieving<br />
the BCA’s performance outcomes. For<br />
example, a particular part of a building<br />
may not comply with the deemedto-satisfy<br />
solution. Yet by increasing<br />
the stringency of another part of the<br />
building, overall compliance with the<br />
intent can be reached.<br />
The analysis process is a complex one<br />
requiring a great deal of engineering<br />
judgement in developing the energy<br />
analysis, and this is where one of the big<br />
market failures occurs.<br />
Energy analysis software is a tool. And<br />
like any tool it requires a certain level<br />
of expertise to be used effectively. If<br />
software users don’t know exactly what<br />
they’re doing then getting the desired<br />
results will prove difficult indeed, if not<br />
impossible.<br />
To be able to effectively use the tool<br />
a designer/engineer must have a<br />
thorough understanding of building<br />
services - predominantly mechanical<br />
– and a building’s thermal properties,<br />
and how the two integrate as an overall<br />
system.<br />
Performance measurement is something<br />
those in the built environment are<br />
yet to fully embrace, much to its own<br />
detriment. Very rarely do we hear of<br />
designers assessing the building to test<br />
the accuracy of assumptions applied,<br />
and then learning in an iterative manner<br />
how to improve the modelling process.<br />
This must change, and it will.<br />
Q: I understand that there has been<br />
an ongoing debate as to whether<br />
the compliance criteria in Section<br />
J of the building code should be<br />
expressed in terms of absolute values<br />
such as Mega Joule/annum or star<br />
ratings as against an approach that<br />
compares the proposed building<br />
with a hypothetical building model<br />
that is prescriptively described as<br />
complying. Which do you prefer?<br />
PW: Although there is some debate<br />
about whether the output should be in<br />
MJ/m2/annum or in greenhouse CO2<br />
equivalent or stars, from a technical<br />
point of view this is a minor issue. A<br />
simple conversion factor allows a design<br />
engineer to easily punch out results in<br />
the desired metrics.<br />
The more pressing issue is a set of<br />
industry-standardised input guidelines.<br />
There are three main drivers for the<br />
use of energy-analysis software: BCA,<br />
NABERS and Green Star. All three have<br />
differing input parameters, which is<br />
cumbersome to say the least. Some<br />
of the protocols require the use of USbased<br />
parameters, while others require<br />
the use of <strong>Australian</strong> based parameters,<br />
such as the metabolic rates of<br />
occupants. I also understand parameters<br />
around occupancy rates vary.<br />
It would make a lot more sense if the<br />
industry could come together to agree on<br />
a set of common parameters. This would<br />
greatly reduce remodelling to meet<br />
each rating criteria.” See an extract from<br />
Ecolibrium on page 26 for more on this.<br />
I don’t believe there is a pressing<br />
requirement for another building<br />
analysis software package; there are<br />
several available that are more than<br />
adequate. What we do need, however,<br />
is industry agreement and alignment of<br />
modelling procedures and parameters<br />
used in Australia.<br />
If there were to be one software<br />
program it would require considerable<br />
investment to develop it, and substantial<br />
continuing maintenance costs.<br />
The various software packages currently<br />
in use vary to some degree in their<br />
calculations, their inputs and their<br />
results, so the comparative approach in<br />
JV3 is a more practical one if a market<br />
featuring different software is to<br />
continue.<br />
So that the various available systems<br />
can be better modelled, there needs<br />
to be improved communication and<br />
sharing between software developers<br />
and mechanical services equipment<br />
manufacturers. It would be of<br />
tremendous assistance for manufactures<br />
to measure their equipment’s<br />
performance and then share the results.<br />
The end result will be much more<br />
accurate and realistic system modelling.<br />
And isn’t that what everybody wants?<br />
Q. Do you see a need for the current<br />
energy analysis software to be<br />
accredited or for practitioners to be<br />
accredited as users?<br />
PW: Yes, accreditation is definitely<br />
needed.<br />
There is a perception in the marketplace<br />
that anyone, including ESD engineers<br />
with no real knowledge of building<br />
services systems, and home energy<br />
raters wanting to branch into a new<br />
market, can use this software and<br />
achieve the desired output.<br />
24 • <strong>Australian</strong> <strong>Building</strong> Regulation Bulletin
The reality, however, is that commercial<br />
energy analysis is a complex topic<br />
and needs a substantial amount of<br />
engineering judgement to ensure<br />
maximum accuracy. Commercial<br />
building software models the<br />
interactions of the building services<br />
systems with the physics of the building,<br />
whereas home energy rating software<br />
doesn’t have anywhere near this level of<br />
complexity.<br />
Only competent engineers and building<br />
services engineers should be using this<br />
type of software.<br />
Software that can be used in BCA<br />
performance modelling is already<br />
‘accredited’ against ‘best-test’, as I<br />
understand it.<br />
Two steps to user accreditation and<br />
capability are desperately required. The<br />
first is an accreditation to demonstrate<br />
competency in applying the modelling<br />
process and engineering principles<br />
–irrespective of which software is used.<br />
The next level of training should be a<br />
tool-specific scheme, aimed at those<br />
who have passed the first level, who<br />
can then learn how to use individual<br />
software packages.<br />
AIRAH is well placed to develop<br />
and administer such a system, in<br />
collaboration with the eight building<br />
control administrations, and with<br />
funding from the government.<br />
Many countries are grappling with these<br />
issues, and given its strong international<br />
links, AIRAH is well placed to learn from<br />
overseas experience.<br />
Q: Do you see the modellers who<br />
using energy analysis software being<br />
specialists in building sustainability/<br />
energy analysis, or is there a need<br />
for them to first have gained HVAC<br />
experience as designers or installers?<br />
PW: The programs used for building<br />
energy analysis are very complicated,<br />
and users need a very good level of<br />
understanding of HVAC systems.<br />
The software is considerably more<br />
complex than that designed to measure<br />
house energy rating, which most<br />
building practitioners can master quite<br />
quickly.<br />
It’s easy to select totally inappropriate<br />
systems or other inputs from the various<br />
menus, delivering a result that would<br />
look impressive and creditable to<br />
somebody not trained in HVAC system<br />
design.<br />
Q: It would seem that the current<br />
software programs need to make<br />
certain assumptions, such as<br />
whether the systems have been<br />
properly commissioned, or whether<br />
the building is well constructed to<br />
reduce infiltration, or whether or<br />
not the building is likely to be well<br />
maintained. How realistic are the<br />
assumptions being made?<br />
PW: These are aspects where building<br />
and HVAC design and construction<br />
experience is essential. Good<br />
engineering judgement is crucial in<br />
estimating what the inputs should be.<br />
The detailing of facades or roof-to-wall<br />
interfaces as well as air-locks and other<br />
seals give a good indication of the likely<br />
infiltration that needs to be an input<br />
and not a hypothetical ‘ideal’ value.<br />
We are starting to see some buildings<br />
pressure tested and gaps in the building<br />
envelope sealed to prevent uncontrolled<br />
infiltration.<br />
Commissioning and good maintenance<br />
are extremely important in<br />
achieving the assumed ongoing<br />
energy consumption. No one is held<br />
accountable for this currently, and until<br />
they are there will be continuing market<br />
failures in this space. Both of these issues<br />
have been talked about for years, and<br />
unless they are regulated or energy<br />
prices skyrocket, I don’t believe they will<br />
be genuinely addressed. Perhaps the<br />
introduction of mandatory disclosure<br />
will start to drive some good outcomes.<br />
We certainly hope so.<br />
What I’ve said here is my opinion, but<br />
it’s based on discussions I’ve had with<br />
– and input from - stakeholders across<br />
our industry. This includes several<br />
prominent AIRAH members, who are<br />
daily working with building simulation<br />
software at the vanguard of measuring<br />
the built environment’s performance.<br />
These are professionals helping to shape<br />
the future of our cityscapes by making<br />
sure our buildings perform as they<br />
should in the present.<br />

OPINION<br />
Where’s the consistency?<br />
AIRAH life member<br />
Murray Mason believes<br />
there is an avoidable lack<br />
of commonality between<br />
Australia’s various building<br />
schemes and codes.<br />
For a number of years now my company<br />
has being working on developing a<br />
building energy estimation program<br />
(BEAVER) that incorporates several<br />
enhancements. These include features<br />
to assist users in gaining compliance<br />
with the BCA, and to achieve ratings<br />
with NABERS and Green Star.<br />
A number of the program’s users<br />
have indicated they are frustrated<br />
at the lack of consistency between these<br />
codes, rating schemes and the relevant<br />
<strong>Australian</strong> standards. On many items<br />
there is a lack of commonality that<br />
is unnecessary, leading to extra costs<br />
being imposed on design consultants,<br />
contractors and software developers.<br />
My company, ACADS-BSG, is<br />
involved in continuing consultation<br />
with the <strong>Australian</strong> <strong>Building</strong> Code<br />
<strong>Board</strong> through the normal process<br />
of public review and comment. We<br />
have also been, albeit less formally,<br />
commenting on certain aspects of the<br />
Green <strong>Building</strong> Council of Australia,<br />
making suggestions and comments.<br />
Many of these comments are in relation<br />
to the practical application of some of<br />
the requirements for compliance. There<br />
are also some unnecessary variations<br />
between the rating schemes/codes.<br />
A few examples of this are listed here:<br />
• Why do each of the rating/codes<br />
schemes have different profiles for<br />
people, lights, equipment and plant<br />
operation for the same building type?<br />
• Why do they use different<br />
metabolic rates for people?<br />
• Why are the metabolic rates different<br />
to those used in normal design?<br />
• Why are the lighting and<br />
equipment levels different?<br />
• Why does Green Star have, within<br />
each building type, different room<br />
functions, while NABERS and BCA<br />
have only a building type?<br />
For example BCA has Schools<br />
while Green Star have Schools and<br />
Universities and within each of these<br />
different functions – classrooms, dry<br />
labs, wet labs, gymnasiums – with<br />
different profiles and metabolic rates.<br />
• Similarly, why do the building types<br />
and functions differ from those listed<br />
in AS1668?<br />
• Why does the BCA use Table D1.13<br />
(which is for fire egress) for people<br />
occupancy rather than AS1668, to<br />
which Green Star refers?<br />
The list goes on.<br />
Murray Mason<br />
In addition, however, there are<br />
provisions, particularly with Green Star,<br />
that make us wonder about the quality of<br />
technical advice these organisations are<br />
receiving. It shows a lack of experience<br />
and understanding in the use and<br />
application of simulation software<br />
and in the design process itself.<br />
For example, with some of the Green<br />
Star guideline documents, profiles for<br />
metabolic rates are listed, rather than those<br />
for occupancy – no energy simulation<br />
program inputs data in this way.<br />
Another example is the selection of the<br />
climatic data to be used with the Green<br />
Star guideline documents. They all state<br />
that when there is a lack of an available<br />
local TRY year, an actual year of recorded<br />
weather data from a location within<br />
50km of the building location is to be<br />
used. If that is not available an average<br />
is to be taken from the three nearest<br />
locations within 250km.<br />
Hence, if a Green Star Rating for a<br />
building in Tewantin in Queensland is<br />
required (this is a case in point where<br />
one of our users sought our advice) then<br />
climatic data from Brisbane, Amberley<br />
and Oakey should be averaged.<br />
Getting hourly solar and ground-recorded<br />
data from the Met Bureau is difficult<br />
enough. To “average” three locations is<br />
just ridiculous and totally impractical.<br />
Because we supply simulation software to<br />
the industry, we are continually asked by<br />
our users for advice on particular aspects<br />
of the rating schemes and the BCA.<br />
We are also confronted with providing<br />
means of inputting different data into our<br />
energy program as a function of which<br />
rating scheme is being used when there<br />
is no practical reason why the data<br />
should be different.<br />
Because of the company’s collective<br />
years of experience in the industry, we<br />
have devoted a lot of time attempting to<br />
convince those responsible for these rating<br />
schemes and codes to make changes.<br />
However, our business is developing and<br />
supporting software. Because of this<br />
we do have a good appreciation of the<br />
requirements, but we are a single voice<br />
and our opinions and concerns are not<br />
necessarily representative of the industry.<br />
It is not our role to convince the code<br />
makers to adopt a consistent approach.<br />
It is an industry responsibility.<br />
I believe, therefore, that it would<br />
be appropriate for AIRAH to set up<br />
an advisory technical committee<br />
representing the industry (with<br />
support from government and with<br />
some influence) to provide advice and<br />
guidance to the three organisations that<br />
are developing the BCA, NABERS and<br />
Green Star, and to ensure that there<br />
is compatibility with design practice.<br />
This committee could also review the<br />
appropriateness of having three separate<br />
protocols to achieve reductions in<br />
greenhouse gas emissions.<br />

Doors open on Australia’s first zero-emission home<br />
Designed to fit the <strong>Australian</strong> climate<br />
– and the lifestyle of a typical middleincome<br />
family – Australia’s first Zero<br />
Emission House (AusZEH) was officially<br />
opened in Melbourne in April.<br />
Working with industry partners Delfin-<br />
Lend Lease and the Henley Property<br />
Group, and supported by the AusZEH<br />
consortium, CSIRO designed and built<br />
the demonstration house 30 kilometres<br />
north of Melbourne’s CBD, in the<br />
community of Laurimar in Doreen,<br />
Victoria.<br />
The eight-star energy-efficiency rated<br />
AusZEH showcases off-the-shelf building<br />
and renewable energy-generation<br />
technologies, and new future-ready<br />
energy management systems.<br />
Nearly 13 per cent of Australia’s<br />
greenhouse gas emissions are due to<br />
home energy use.<br />
The AusZEH is designed to produce<br />
enough ‘zero-emission’ electricity<br />
from 6kW solar panels to supply all<br />
the operating energy needs of the<br />
household so that its net total CO2 or<br />
other greenhouse gas emissions is zero.<br />
The Director of CSIRO’s Energy<br />
Transformed Flagship, Dr Alex<br />
Wonhas, says the uptake of zeroemission<br />
housing in Australia could<br />
have a significant impact<br />
on reducing emissions<br />
nationwide.<br />
“CSIRO scientists estimate<br />
that if all the new housing<br />
built in Australia between<br />
2011 and 2020 were zeroemission<br />
houses, 63 million<br />
tons of greenhouse gas (GHG)<br />
emissions would be saved,”<br />
Dr Wonhas said.<br />
“This would be equivalent to<br />
taking all of Australia’s private<br />
cars off the road for two years<br />
and 237 days, or closing all<br />
Australia’s power stations for<br />
up to 100 days.”<br />
CSIRO’s Energy Transformed Flagship<br />
initiated the AusZEH project to<br />
demonstrate and evaluate how lowcarbon<br />
housing can be achieved in<br />
Australia to reduce GHG emissions and<br />
create a more sustainable future for the<br />
nation.<br />
For 12 months, the AusZEH<br />
demonstration house will become a<br />
home for an <strong>Australian</strong> family and a<br />
laboratory for CSIRO.<br />
The house has been fitted with a unique<br />
energy management system developed<br />
by La Trobe University in partnership<br />
with CSIRO, which tracks energy use<br />
The first AusZEH demonstration house is open for inspection at Laurimar in Doreen, Victoria. The eight-star energy<br />
efficiency rated house, which features a state-of-the-art energy management system, will produce enough zero<br />
emission, renewable electricity from roof-top solar panels to supply all its electricity needs.<br />
The AusZEH demonstration house is equipped with a unique homeenergy<br />
management system.<br />
in the house and provides feedback<br />
via customised reports to household<br />
members.<br />
This information on the performance of<br />
the ‘living’ house will be used to identify<br />
ways to improve the design of future<br />
zero and low-emission houses.<br />
“Our greatest impact comes through<br />
partnerships with others,” Dr Wonhas<br />
said.<br />
“Through the AusZEH consortium,<br />
expertise from CSIRO, industry,<br />
university and government partners<br />
have been combined to create a<br />
demonstration house which provides an<br />
example of how <strong>Australian</strong>s can achieve<br />
a more sustainable future living in their<br />
homes.”<br />
The AusZEH consortium membership<br />
includes: CSIRO, Delfin Lend Lease, Henley<br />
Property Group, La Trobe University,<br />
Sustainability Victoria, SP AusNet, Telstra<br />
and the Victorian Department of Human<br />
Services.<br />
CSIRO initiated the National Research<br />
Flagships to provide science-based<br />
solutions in response to Australia’s major<br />
research challenges and opportunities.<br />
The 10 Flagships form multidisciplinary<br />
teams with industry and the research<br />
community to deliver impact and benefits<br />
for Australia.<br />

Grocon’s carbon neutral Pixel <strong>Building</strong><br />
Grocon has developed the Pixel building<br />
in a manner that is so environmentally<br />
advanced, there’s nothing presently like<br />
it in the world. Pixel is Grocon’s “Future<br />
Office” – a prototype of the buildings<br />
that will emerge when a carbon<br />
constrained environment demands a<br />
greater focus on energy efficiency.<br />
Existing environmental rating tools do<br />
not yet place a significant importance<br />
on the issue of carbon pollution.<br />
Grocon’s Pixel building is an insight into<br />
the way buildings of the future will be<br />
designed, built and managed in order to<br />
tackle the carbon cost issue head on.<br />
Pixel is aiming to achieve the highest<br />
environmental rating ever for buildings<br />
using the US LEED, UK BREEAM and<br />
<strong>Australian</strong> Greenstar environmental<br />
rating schemes. To put that into context,<br />
there are approximately 740,000<br />
buildings registered worldwide under<br />
those three rating schemes,<br />
and Pixel would be at the<br />
forefront of all of them.<br />
In anticipation of the<br />
worldwide move to carbon<br />
neutral buildings, Pixel has<br />
been designed to generate<br />
more energy on site than it<br />
uses, thus off-setting carbon<br />
generated to run the building.<br />
But Pixel goes further by<br />
generating more energy in<br />
order to offset the carbon<br />
used to build it and so the<br />
building becomes carbon<br />
positive, giving the energy it<br />
generates back to the grid.<br />
In addition to tackling the<br />
carbon issue head on, Grocon<br />
has designed Pixel to be water<br />
balanced. That means that if<br />
Melbourne maintains the 10<br />
28 • <strong>Australian</strong> <strong>Building</strong> Regulation Bulletin
year average rainfall levels from 1999-<br />
2009, then Pixel will be self sustainable<br />
for water supply. The building could<br />
theoretically be disconnected from the<br />
grid and continue to safely operate.<br />
Through Grocon’s work at Pixel, new<br />
technologies have been developed, new<br />
systems have been brought to Australia<br />
and there has been significant “green”<br />
upskilling of both Grocon’s workforce<br />
and their sub-contractors.<br />

kind in Australia.<br />
Suitable for both commercial and<br />
domestic use, where there is demand<br />
for large volumes of hot water, the<br />
Bosch 32C boasts a 6-star energy rating,<br />
making it the most efficient commercial<br />
gas hot water unit on the market.<br />
The product’s edge is its unique<br />
‘condensing technology’, which creates<br />
a superior level of energy efficiency –<br />
more than 94%.<br />
Unlike traditional hot water systems,<br />
Bosch’s condensing technology captures<br />
waste heat from exhaust gas and uses<br />
it to preheat incoming cold water. The<br />
effect is an energy saving of more<br />
than 15.5%, compared to a standard<br />
continuous flow commercial system.<br />
Bosch National Commercial Manager,<br />
James Smith, said the environmental<br />
benefits of the Bosch 32C made it far<br />
superior to any other commercial model<br />
available, setting a new benchmark for<br />
the industry.<br />
“Choosing this system for a commercial<br />
project is the equivalent of taking one<br />
and half cars off the road for an entire<br />
year, saving tonnes of greenhouse gas<br />
emissions and major dollars in terms of<br />
running costs*.”<br />
He said the new product gave builders,<br />
architects, hydraulic consultants<br />
and plumbers the opportunity to<br />
meet and exceed the <strong>Australian</strong><br />
<strong>Building</strong> Code <strong>Board</strong>’s latest energy<br />
efficiency provisions, while reducing<br />
environmental impact and energy costs<br />
for their clients.<br />
Designed specifically for commercial<br />
developments and large homes, the<br />
Bosch 32C (along with the 32 standard<br />
model) is the only true commercial unit<br />
on the market and the only continuous<br />
flow system able to be installed<br />
internally or externally.<br />
“The unit has dual heat exchangers,<br />
one for primary heating and one for<br />
secondary heating. A 100% stainless<br />
steel exchanger uses residual heat from<br />
exhaust gases to help preheat incoming<br />
water prior to it entering a primary<br />
copper heat exchanger,” Mr Smith said.<br />
“The copper heat exchanger is coated to<br />
prevent corrosion and deterioration, and<br />
the internal copper piping is 25% thicker<br />
than any other model,” he said.<br />

The Bosch 32C was developed in line<br />
with Australia’s Ecologically Sustainable<br />
Development (ESD) standards, and to<br />
complement Bosch’s existing range of<br />
energy efficient products.<br />
The domestic condensing model,<br />
the Bosch 26eco+, with a 6.9-star<br />
energy rating, was recently named the<br />
GreenPlumbers ‘Product of the Year’<br />
(2009), demonstrating the superior<br />
ecological benefits of the Bosch<br />
condensing range.<br />
The Bosch 32C is available from local<br />
plumbing suppliers or by contacting<br />
the Bosch Customer Service Hotline<br />
on 1300 30 70 37.<br />

Philips Innovation: the MASTER TL5 Eco<br />
Philips most recent energy saving<br />
innovation is the MASTER TL5 Eco.<br />
This unique range reduces energy<br />
consumption by 10% without reducing<br />
lighting quality. These savings are<br />
made possible by the unique mix<br />
of filling gases and new phosphor<br />
technology which improves lighting<br />
output while reducing energy<br />
consumption. The MASTER TL5 Eco 25W<br />
lamps are a direct replacement for a<br />
regular TL5 28W and in the application<br />
provides the same light output - 2900<br />
lumens.<br />
The benefit of a true retrofit solution<br />
is the ease of use. MASTER TL5 Eco<br />
lamps are designed to work in all the<br />
applications that currently use the<br />
conventional TL5 lamps and therefore<br />
make them perfect for relamping<br />
existing TL5 luminaires as well as new<br />
buildings and renovations.<br />
But energy saving isn’t the only<br />
benefit of MASTER TL5 Eco. All of<br />
the existing specifications that have<br />
made Philips TL5 a popular choice<br />
have been included in this new<br />
technology : low mercury, (1.4mg),<br />
long lifetime, high CRI and ability to<br />
be dimmed, mean that this unique<br />
range can be included in almost all<br />
applications where TL5 is specified.<br />
Philips now offers a range of TL5<br />
Eco lamps that will offer energy<br />
saving options for most current TL5<br />
applications. We see this as a major step<br />
towards making energy saving easy to<br />
experience for all customers, while not<br />
compromising on lighting quality.<br />

BCA PRODUCT + iNDUSTRY INNOVATION NEWS<br />
Windows Fit For Purpose<br />
The BCA calls up windows that comply<br />
with AS 2047. Are you using products<br />
that comply?<br />
It is your responsibility to ensure your<br />
window manufacturer has compliance<br />
to AS 2047 or it will end up costing the<br />
builder or the owner a lot of money.<br />
Don’t take any chances! All AWA<br />
members undergo performance tests to<br />
verify performance claims.<br />
What is AS 2047?<br />
It is the mandatory minimum<br />
specification for windows and doors<br />
used in Australia it includes compliance<br />
to the Glass Standard AS 1288.<br />
The following performance tests<br />
are undertaken to verify product<br />
performance claims.<br />
1. AS 4420.2 Deflection Test – positive<br />
and negative wind pressures are<br />
applied to the face of the window to<br />
test the maximum deflection under<br />
wind load.<br />
2. AS 4420.3 Operating Force Test – to<br />
verify that an opening sash is capable<br />
of opening and closing without<br />
undue effort.<br />
3. AS 4420.4 Air Infiltration Test – the<br />
air leakage of a window is tested<br />
to ensure energy and acoustic<br />
efficiency.<br />
4. AS 4420.5 Water Penetration<br />
Resistance Test – this test is<br />
designed to ensure no water leaks<br />
through the window into the<br />
building.<br />
5. AS 4420.6 Ultimate Strength Test –<br />
negative and positive wind pressures<br />
are applied to the window to at least<br />
1.5 times the design wind pressure to<br />
ensure it does not fail in unusual wind<br />
conditions.<br />
All windows and doors for homes<br />
must have a Performance Label which<br />
confirms that they are certified to<br />
comply with <strong>Australian</strong> Standard AS<br />
2047. If you purchase windows from an<br />
accredited AWA member, you can also<br />
receive a Certificate of Compliance that<br />
supports a 7 year warranty.<br />
Example: Window label which should<br />
be affixed to window and door products<br />
to ensure compliance to AS 2047.<br />
All AWA<br />
members have<br />
products tested<br />
to AS 2047 and<br />
are a part of<br />
a third party<br />
NATA accredited<br />
program. This<br />
accreditation<br />
program is a proven and nationally<br />
recognised method of achieving<br />
compliance to assist builders, specifiers<br />
and homeowners to select products that<br />
comply with <strong>Australian</strong> Standards.<br />
Look for these logos when purchasing<br />
your windows to be<br />
confidant you are<br />
purchasing compliant<br />
products.<br />
