Climate Action 2010-2011

Builder of a Sustainable

Builder of a Sustainable Future Having developed over 22,000 luxurious quality homes in the past 45 years and as one of Singapore’s largest landlords, City Developments Limited has been instrumental in shaping the cityscape with architectural icons. Beyond redefining lifestyles and presenting innovative living concepts, this green developer has also been leading the transformation of Singapore’s built environment and social landscape. According to the Intergovernmental Panel on Climate Change (IPCC), buildingrelated greenhouse gas emissions could almost double by 2030. The building sector is amongst the largest source of greenhouse gas emissions, consuming more than a third of the world’s energy. These startling figures present big opportunities for change. One firm advocate of environmentally sustainable development is Singapore’s foremost property developer – City Developments Limited (CDL). Firmly rooted in the Company’s ethos is the belief that a successful corporation is not only founded on financial achievements, but is also shaped by the positive contributions it can make to society and towards environmental sustainability. This approach has remained a guiding principle by which CDL conducts its business and engages with its stakeholders and the larger community. Since the 1990s, CDL has been setting the benchmark for Green Building in Singapore, taking bold steps towards mitigating the impact of its operations on the environment, and striving to apply environmentally-friendly practices in its business. As part of its corporate green strategy, the Company champions a three-pronged holistic life-cycle approach towards sustainability: DEVELOP Quality and Environmentally-Sustainable Residential and Commercial Properties MANAGE Properties in a Cost-Efficient and Energy-Efficient Way CDL’S THREE-PRONGED STRATEGY INFLUENCE Stakeholders Through Community Outreach Initiatives BUILDING CAPACITY IN GREEN INNOVATION As a testament to the importance CDL places on the environment, it currently invests between 2% and 5% of construction cost of a development on green design and features. The returns of this investment are reflected in the reduced use of natural resources, financial savings and eventually, the possible increased capital value of the development. Moreover, through the implementation of green innovations into CDL properties, it is also helping to develop the industry’s expertise and capabilities in adopting sustainable solutions for Singapore’s built environment. CDL has set numerous new industry firsts through the implementation of state-of-the-art technology and green innovation within its residential and commercial developments. One exceptional showcase of a sustainable green building is its 300,000 square feet commercial building, 7 & 9 Tampines Grande, which was completed in 2009. Designed as a cutting-edge, new generation green office, Tampines Grande features one of the largest and most extensive use of solar technology in a commercial property in Singapore, with Building Integrated Photovoltaic (BIPV) and Solar Thermal panels measuring some 2,080 square metres installed on its roofs and facade that generates 203,000 kWh of clean energy.

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).
