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 />

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 />

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 />

The Program is the first key action<br />

under Jobs for the Future Economy,<br />

a new strategy to facilitate green<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 />

Control System<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 />

a manufacturer’s reliability in producing<br />

structural steel materials. Meanwhile,<br />

FPC certificates to manufacture EN<br />

steel materials under the European<br />

Union Construction Product Directives/<br />

Regulations or API Monograms, both<br />

are already widely recognised in the<br />

European markets and the oil and gas<br />

industry respectively, are considered<br />

‘acceptable in lieu’, under the provision<br />

of BC1.<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 />

Nigel Carpenter<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 />

Extract from Ecolibrium, March 2010 Edition.<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 />

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 />

system, positioned as the only one of its<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 />
