Haden
Engineering, a Norfolk Group Ltd. (ASX: NFK) company within its
Mechanical division, has won the Commercial Mechanical Services
Subcontractor Award at the 2008 Master Builders Excellence in
Construction Awards held in Canberra.
Haden was honoured for its mechanical services design and
construction work for Section 84 Building B – the new Australian
Taxation Office building in Canberra.
David Rafter, Chief Executive of Norfolk’s Mechanical division, said
the company is especially proud of this award.
“While we have been increasingly involved with a number of ABGR and
Green Star rated construction projects, Section 84 was the first 4.5
ABGR and Green Star building project where we had responsibility for the
design as well as construction,” Mr Rafter said.
“The project brief required an ABGR of 4.5, and while achieving this
presented some challenges for us, it has led to several energy
innovations that are new to construction. Some of the innovations in
HVAC included low temperature supply air and low airflow rates. These
have resulted in capital cost saving for the installation and also saved
floor space for the tenants,” explains Mr Rafter.
A high performance façade system was developed to minimise the
external heat transmission and solar load into the space. Also, in order
to reduce energy consumption, the quantity of air to be circulated was
reduced significantly from traditional design levels. With a reduction
in the air quantity an increase in the temperature difference of the air
was required in order to provide the necessary cooling capacity.
“This presented another challenge of maintaining comfortable
conditions at low air flows and low air temperatures as this situation
can easily result in drafts, stuffiness and hot and cold spots. We
solved this through the use of air diffusion capable of effectively
supplying the air at these conditions into the space,” Mr Rafter
concluded.
The Master Builders Association is Australia’s major building and
construction industry association. The Master Builders Excellence in
Building Awards is the building and construction industries’ premier
awards event of the year celebrating excellence in the industry.
