SOLAR PROTECTION
COOLING
TOWERS
External shading to reduce
discomfort glare, increase thermal
comfort, minimise solar gains and
reduce cooling requirements
GREEN ROOF
RAINWATER
Reduce heat island effect,
stormwater attenuation and
improved thermal insulation
RAINWATER RECYCLING
Collection of rainwater from
roof for reuse in landscape
irrigation for the public domain
SECURE BICYCLE RACKS
Secure bicycle racks and
change facilities to encourage
staff bicycle commuting
BLACKWATER TREATMENT SYSTEM
Treatment of building waste water
(
including toilet and urinal waste) for
re-use throughout the building for
non-potable requirements such as toilet
flushing, irrigation, and cooling towers
PASSIVE CHILLED
BEAM COOLING
Warm air rises through perforated
metal ceilings and is cooled by
beams which have chilled water
reticulated through them
SINGLE PASS
AIR-CONDITIONING
100%
fresh air is supplied to the
working zone and is exhausted out
the building via the atrium

AN
ENVIRONMENTAL
DESIGN
CONCEPT
Social Sustainability
Creating long-term activation
and a green precinct for the
whole community. Place making
initiatives include urban
connections, high-quality retail,
children’s theatre, innovative
playground and community green.
Integrated Fit Out
The Commonwealth Bank fit out
was integrated with the base
building design and construction
to avoid material waste. Many
sustainable innovations have
been used in the fit out including
Activity Base Working, a mini
tri-gen system, media walls with
sustainable data and low VOC
materials.
Building Form
&
Urban Design
Darling Quarter creates a
permeable, unified and legible
precinct, reforming an area that
previously was cluttered, disparate
and opaque. The two building
forms flank a new at-grade
pedestrian connection that
connects the precinct to the city
and creates a gateway to Darling
Harbour South. New high-quality
retail concessions, an expansive
children’s playground and other
public domain improvements
on the ground plane respond
to the desire to make this an
environmentally and socially
sustainable development.
High Performance
Building Envelope
The innovative design of the
building envelope maximises the
energy efficiency and thermal
performance of the building. The
envelope balances the need for
daylight penetration, external
views, thermal comfort, glare and
solar gain control.
Energy Efficient Systems
and Technology
The provision of a high
performance envelope enabled the
design team to select low-energy
mechanical cooling systems. The
building also incorporates low
carbon technologies for energy
generation and efficient building
systems.
Water Saving Initiatives
Darling Quarter employed the
following strategies to achieve a
92%
reduction in potable water
consumption:
High efficiency fixtures and
fittings
Rainwater harvested from the
roofs is filtered, UV treated and
distributed to the public domain
for landscape irrigation. It is
predicted to reduce the potable
water use in the public domain
by 94%.
An innovative blackwater
treatment and reuse system
coupled with sewer mining
to maximise the use of non-
potable water.
The sewer mining and black
water treatment system installed
within the building were
designed to treat and recycle
100%
of the blackwater generated
by the building, through
sourcing additional effluent
from the sewer mains.
