innovating to reduce energy
2 Victoria Avenue (Durack II) is WA's first 6 Star
Green Star rated building. Its innovative features
include three wind turbines on the rooftop to
provide green energy to a proportion of the
building. e turbines are connected in parallel
to the main grid to reduce the demand for
conventionally produced electricity.
Active chilled beams are used as the primary
source of air conditioning -- a first for a large scale
Perth development. ey offer significant energy
saving with less air handling power required.
Automated louvres, which respond to solar
detection, allow the building to maintain views
and natural lighting, while reducing the radiant
temperature and glare. Says John-Paul Davies
(Woodhead): "A building needs to respond to
its environment and that is what the automated
louvre system does on the western facade of the
building. It maximises the potential opportunities
of the space by reducing the direct heat glare
in the afternoon and then the louvres return to
horizontal when there is no direct solar on them. It
enables the people within the building to maintain
that fantastic view. "
monitoring materials, increasing
recycled content and minimising waste
235 St Georges Terrace was awarded Perth's first
5 Star Green Star accreditation. It incorporates the
heritage listed Bishops See House (residence of the
first Anglican Bishop of Perth) and gardens which
have been opened to the public as a result of the
development. It has a dedicated storage area for
the separation, collection and recycling of office
consumables and a 100 percent fully integrated
fitout to minimise material wastage.
e brief stated that 60 percent of its structural
steel was to have a post-consumer recycled
content greater than 50 percent, and sustainable
timber was specified for all base building
construction timber products.
utilising eco-e cient systems
235 St Georges Terrace incorporated eco-
efficient technology including high efficiency
T5 lighting throughout. Says Richard Kilbane
(Hawaiian): "We used the right type of fluoro
that doesn't use as much power as the earlier
ones. With the layout, we arranged them so
that there are fewer than you would typically
have in an office. You usually see pairs of
them but here they are single and spread out.
A lot of work went into the modelling to work
out how efficiently to lay them all out."
providing sustainable transport
opportunities for tenants
e 100 St Georges Terrace development
-- a 24 level office tower -- sits in the centre
of the CBD and has a 4 Star Green Star rating.
Its parking area has small car spaces to
encourage the use of energy efficient vehicles,
cyclist facilities including secure bike spaces,
showers, lockers and change areas for at least
10 percent of tenancy occupants.
2 Victoria Avenue introduced a grey-water
treatment system to recycle shower and hand
basin water, which is then used for toilet
flushing. e urinals are waterless and the
toilets are dual flush. e landscaping irrigation
is via a subsoil drip system with automatic
timers that incorporate a rainwater/soil
moisture sensor control override.

our economy; it's a choice between prosperity
and decline." - President Barack Obama
