The Transport Accident Commission (TAC) in Victoria has relocated to
purpose-built offices in the heart of provincial city Geelong, 80 km south west
The move is part of the Victorian Government's pledge to build regional Victoria
and sees the TAC occupy an office complex awarded a 5 Star Green Star – Office
Design V2 Rating by the Green Building Council of Australia (GBCA). The
certified rating evaluates the environmental potential of the building and a
rating of five green stars signifies Australian excellence.
The eight level complex is more than just a new headquarters for TAC. The ground
floor has a retail component and includes a gymnasium, café, travel agent and
newsagent; there are also three levels of fully enclosed carparking. All up the
complex will have 16,285 square metres of net letable area (NLA).
Entire Mechanical Services Project Manager Garry Muscat said ventilating the 338
space carpark, split across three levels in the TAC complex, was made more
difficult by the fact that the carpark was fully enclosed and that the ceilings
“The FKP Property Group was keen to look at alternatives to the traditional
carpark exhaust system which would have required a lot of bulky ductwork and in
some places where space was limited, ducting made from load bearing
Steel-Styrofoam panel,” Gary said.
“Furthermore, the developers support sustainable energy efficient designs and
wanted a cost effective system that had good performance figures. They liked the
idea of using JetVent fans which had a low vertical height and were economical
to run and install.”
A carpark impulse ventilation system can help to minimise major capital costs in
several ways. It reduces the time it takes to install and commission, eliminates
the need for expensive ducting, and reduces the pressure requirements for the
main supply and exhaust fans, which therefore has the potential to lower the
cost of the fan. Deciding to use a ductless system early in the building design
can also reduce the level of expensive excavation required for the basement.
Ongoing power consumption costs can also be reduced by using smaller fans and
controlling the speed and usage of the fans based on the demand. Removal of most
of the ducting could also drop the overall cost of maintenance and repairs.
Fantech engaged a computational fluid dynamics (CFD) consultant to optimise the
design and ensure the mechanical design would comply with performance criteria
set out in the Building Code of Australia.
Entire Mechanical Services installed 12 JetVent mixed flow induction jet fans
(JIU-CPMF-50N) and a carbon monoxide sensor driven control system to deliver
optimal energy consumption performance.
“The energy efficiency and space saving characteristics of the JetVent system
were duly noted by the GBCA who awarded the developers additional points for
innovation in their green star accreditation,” Garry said.
Mr Muscat said the building was put into operation in January 2009 and the
JetVent fans continue to perform well.
