We will continue to strive for leadership
through innovations in our projects, such
as the incubation of low carbon and
renewable energy supply and generation
solutions. In FY11 we will develop a
Distributed Energy strategy setting out a
pathway for low carbon and renewable
energy (also known as distributed
generation). Our approach is to pilot
and then implement successful projects
at scale, achieving long-term efficiencies.
Communicate: Effectively
communicate our position
and performance.
We have already undertaken a significant
amount of work in the area of climate
change. We engage with all levels of
government and our peers to share our
learnings and partner in research projects.
We also engage with environmental,
social and governance analysts and
participate in the development of a global
common carbon metric for property. This
engagement and communication process
ensures that our prioritisation, reporting
and management of our climate change
response remains relevant.
In FY11 we will work on improving our
communications, making our response
to climate change risk clearer to our key
stakeholder groups.
Energy Efficiency
Over the past year we have continued to
improve how we set and monitor energy
efficiency and emissions targets for each
of our businesses. We have undertaken
a number of energy efficiency projects
and have set minimum standards for
energy efficiency in our operations
and developments.
Commercial Property energy efficiency
Despite difficult economic conditions, we
have continued to manage our greenhouse
gas emissions and increase our capability
in improving energy efficiency within
existing and new buildings. We have also
improved our evaluation of low carbon and
measurable energy solutions.
Using the NABERS Energy rating tool
to benchmark building performance, we
are improving energy efficiency through
capital investment in high-efficiency
chillers, building management systems,
lighting controls and variable speed drives.
Once again we were awarded a number of
grants through the Federal Government’s
‘Green Building Fund’ to implement
initiatives across our office portfolio and
commenced a trial of energy sub-metering
in several shopping centres.
Last year we committed to a NABERS
Office Energy portfolio average rating of
4.5 Stars by FY14. In FY10 we achieved
an office portfolio average of 3.6 Stars. The
NABERS Retail Energy and Water rating
tools were released in early 2010. We have
since prepared ratings for two shopping
centres. We have received confirmation
that our Forster Shopping Centre has
been awarded the 5 Stars NABERS Retail
Energy rating. We will undertake further
NABERS Retail ratings during FY11.

Energy intensity targets are set for the
whole Commercial Property portfolio.
Last year we committed to a 20 per cent
reduction on FY09 figures by FY14. This
target complements our NABERS target
of an average office rating of 4.5 Stars over
the same timeframe, and our commitment
to undertaking Green Star ratings for
development projects.
This year we have had mixed energy
intensity results. The electricity intensity of
our retail centres increased by 4 per cent,
while the electricity intensity of our office
assets (where we have operational control)
was reduced by 5 per cent. While we
are disappointed in the increase in the
intensity from our retail centres, we expect
that embedding minimum standards
for energy efficiency, and training our
retailers on energy efficiency and capital
expenditure on sustainability, will improve
energy efficiency across our retail centres
over the coming year.
Residential energy efficiency
Our Residential business collects energy
data from direct operations and those
undertaken by contractors on-site. This
data is being used to better understand
energy and emissions source and type
and will be incorporated in our energyefficiency
targets by FY12. The majority of
energy use and emissions is associated
with diesel consumed by the heavy
machinery used by civil contractors and
landscapers and this presents a significant
challenge for efficiency improvements.
We have set requirements for energy
efficiency and management in our
Residential sustainability policy and this
includes requirements for all projects to:
• Co-locate services (in a single trench)
to reduce excavation efforts,
• Maximise beneficial solar orientation
of lots,
• Connect dwellings and other buildings
to reticulated natural gas or LPG
where available,
• Provide energy-efficient lighting in
public domain/areas,
• Use or require energy-efficient
hot water systems such as
gas-boosted solar.
In addition, we are building the capability of
Residential employees in energy generation
and management. For example, some
employees participated in a workshop on
distributed energy with CSIRO to explore
opportunities for energy generation and
distribution in our developments.
We are now collecting data related to the
average Nationwide House Energy Rating
Scheme (NatHERS) ratings achieved by
homes being built in our display villages
or as a result of our partnerships with
builders. The NatHERS star rating system
refers to the thermal performance of the
building’s shell.
Retirement Living
The Retirement Living sustainability
policy includes requirements for energy
efficiency and management. In FY10,
an energy infrastructure and usage audit
was conducted in this business unit. We
will use the results of this audit to identify
energy efficiency and saving initiatives in
existing villages and inform the design of
product in future villages.
An important aspect of energy efficiency
and emissions for the Retirement Living
business is how residents access and
use energy. In FY10 we worked with a
solar company to provide discounted
solar panels and helped residents
access government rebates.
