PRESERVING HISTORY
The centrepiece of Perth’s new Cultural Precinct
is a 32-storey, 5-star Green Star awarded Design
and targeted 4.5 star NABERS Energy (Base Build)
office tower. AECOM worked in close collaboration
with developer and construction company Mirvac,
providing a range of multi-discipline building services
for the development and its four-storey annex. The
tower also houses ancillary facilities for the luxury
The Como hotel in the adjacent heritage listed Old
Treasury Building (OTB).
In addition to the challenges of designing mechanical,
electrical, facade, acoustic, fire, hydraulics and
traffic engineering for the high rise building, AECOM
ensured the energy efficiency and sustainability
requirements of the project was paramount in
the design process and included a number of
sustainability initiatives. A significant portion of
energy efficiency can be achieved with façade and
building services optimisation, therefore a detailed
analysis was carried out on the facade which
subsequently resulted in a double gazed façade
system which incorporates vertical shading fins to
maximise views out, whilst minimising direct solar
radiation into the space.
A circa 1,000kW gas powered tri-generation plant
generates electricity for the building. The waste heat
from the process is harnessed to produce hot water and
heating, as well as chilled water through an absorption
chiller. The tri-generation plant services both landlord
and tenant’s services. Amongst other measures is a
grey water recycling plant designed to minimise water
wastage through treatment and re-use on site.
The four-storey annex building accommodates hotel
services, a gym, office & retail space and a swimming
pool, which includes a BMS controlled motorised glazed
façade louvre system providing mixed mode natural /
mechanical ventilation deepening on external conditions.
The project has been successfully completed and hosts
various State Government Departments which occupy
the 30,000 sq m of commercial space it provides.
The project was awarded the Master Builders
Association’s 2016 Bankwest Best Project. It also won
MBA awards for Best State Government Building, Best
Refurbishment or Renovation: Over $10m, Best Historic
Restoration or Renovation and the Jim Saunders
Memorial Judges Innovation Award.
