Climate Action 2010-2011

For builders and consultants, CDL initiated the CDL 5-Star
Environment, Health and Safety (EHS) Assessment System in 2001,
as part of a concerted effort to encourage the improvement of EHS
standards at all CDL development sites. This rigorous system of
checks and balances has successfully improved the environmental
performance at its development sites considerably, with a reduction
of between 3% and 18% in water and energy usage, as well as waste
generated, at the sites in 2009.
Leveraging on its extensive outreach to its network of office and
retail tenants as well as homebuyers and homeowners, engagement
initiatives focusing on encouraging the uptake of environmentallyconscious
behaviour both in the office and at home have also been
introduced. Through such programmes, CDL undertakes the role of
an influencer to create a more environmentally-aware community.
Forty customised large sized 152 Wp amorphous silicon thin-film Building Integrated
Photovoltaic (BIPV) Panels have been installed on Tampines Grande’s facade across
an area of 140 square metres to give an output of 6 kWp. The customised BIPV panels
form part of the facade cladding, replacing conventional glass that would otherwise
have been used.
For the first time in Singapore, an innovative Solar Air-Conditioning
System has been incorporated to generate sufficient air-conditioning
for the atrium. This, along with other energy-efficient features and
the passive low energy architectural design have led to significant
energy savings amounting to 2.7 million kWh per year and an overall
reduction in CO 2
emissions by approximately 1,400 tonnes per year
for the entire building. This development is also the first in Singapore
to achieve the internationally-recognised LEED Gold certification
under the Core and Shell Category from the US Green Building
Council in 2010.
MANAGING ENERGY-EFFICIENT BUILDINGS
In Singapore, buildings account for about one-third of the national
electricity consumption. The vast majority of energy consumption
occurs while a building is occupied, with more than four-fifths of site
energy use typically occurring in the operational phase of a building’s
life. Through energy-efficient improvements, buildings can reduce
their energy consumption, and also reap long-term financial savings.
In line with CDL’s ongoing commitment to enhance the energy
efficiency of its existing buildings, the environmental performance
of each building is closely monitored with a view of implementing
infrastructural enhancements or engagement initiatives to further
improve efficiency.
A recent example is CDL’s Fuji Xerox Towers, a 359,000 square
feet commercial building completed in 1987. Following a retrofitting
exercise in 2008, which saw the replacement of the chiller system
that accounts for the bulk of its energy consumption, a substantial
50% reduction in energy consumption in the chiller plant system or
energy savings of 2,378,000 kWh per year was achieved. With the
implementation of other energy-efficient features such as ultrasonic
and photovoltaic sensors, the building has achieved a 23% reduction
in electricity consumption annually following the retrofitting, and an
Energy Efficiency Index (EEI) of 138.71 kWh/m 2 /yr.
CREATING A CULTURE OF AWARENESS
Apart from infrastructural investment for energy-efficiency, change can
only be sustained through stakeholder engagement and influence.
Leveraging on its sphere of influence as a property developer and
landlord, CDL has introduced several engagement initiatives to grow
a culture of environmental awareness amongst its stakeholders,
including builders and consultants, tenants and homebuyers.
City Square Mall, Singapore’s first Eco-Mall, was envisioned by CDL as a prototype of
an eco- and community-friendly mall that provides a fun eco-learning experience for
tenants and shoppers. Designed with environmental sustainability in mind, the 700,000
square feet Mall is equipped with a comprehensive range of innovative green features
which collectively reduces over 5,700 tonnes of carbon emissions annually.
TOWARDS A CARBON NEUTRAL FOOTPRINT
In 2009, CDL established the 108,000 square feet office project –
11 Tampines Concourse as the first CarbonNeutral ® development in
Singapore and Asia Pacific. This milestone achieved was a natural
progression of CDL’s commitment towards building greener properties
– and a forward-looking approach towards increasing corporate
environmental responsibility and long-term sustainability.
As an affirmation of CDL’s commitment to reduce its carbon footprint,
the Company has embarked on neutralising the carbon emissions of
its corporate office operations and has recently been certified as a
CarbonNeutral ® company.
With governments worldwide galvanising action against climate
change, CDL is poised at the forefront of change to lead Singapore’s
built environment into the new era of sustainable development and
growth, in support of the Singapore government’s announcement to
reduce CO 2
emissions by some 16% below ‘business as usual’ levels
by 2020 (subject to a legally binding global agreement reached).
