Responsible Material Use and Green Procurement

Development and management of buildings involves an extensive use of materials and waste generation. Hence, we set clear guidelines and specifications on the procurement of materials and construction management to reduce the overall impact of our projects across their life-cycle. We also acknowledge that the use of virgin materials can impact the environment and human health. By specifying the use of sustainable and non-toxic building materials in our developments, we can deliver environmental, social, and business benefits.

Beyond adopting good practices in our operations, CDL has had a set of green procurement specifications to promote responsible sourcing along our supply chain since 2008. The guidelines encourage the use of eco-friendly and recycled materials, in alignment with our EHS Policy. An example is the use of non-toxic materials like low volatile organic compounds paint. All our builders, suppliers and vendors of new development projects are required to comply with these guidelines.

For the SSA, which started construction in 2016, at least 80% of the structure was built with Cross Laminated Timber (CLT) and Glued Laminated Timber (Glulam). CLT in particular is harvested from sustainably managed forests. Both the CLT and Glulam used in the construction of the Academy were verified by the Nature’s BarcodeTM system as coming from responsible sources. The system entails scientific tests like DNA analysis to minimise the risk that the wood materials are derived from illegal logging activities.

In anticipation that consumers may shift their preference to low-carbon premises, and carbon construction materials such as steel and cement may become increasingly costly, CDL has set a target to reduce the embodied carbon of our building materials by 24%, instead of their conventional equivalents, by 2030. Monitoring and reporting of the embodied carbon performance of our projects against the adopted targets will enhance CDL’s supply chain management and encourage the use of lowcarbon and recycled alternatives to address and reduce the total emissions impact. An interim target of 7% reduction was set for all new projects awarded from 2018 onwards, where the performance will be monitored closely towards 202016.

At CDL, green features, such as energy-efficient of the lighting and air-conditioning, water-efficient irrigation system and passive cool design architecture, are highlighted in our marketing collateral Eco Page for every residential project development. At the sales galleries, the information is displayed prominently on the Eco Wall to educate and create awareness amongst potential home-buyers. Outstanding green features and facilities such as the smart home devices and free-to-use electric bikes are also highlighted in the cdlhomes website. We also provide Your Personal Green Living Guide to homebuyers during the unit hand over. The green guide explains the green features within the home as well as the common areas, so that residents can better appreciate the sustainability concept that go into the design of the condominiums.

For our tenants, we provide equipment manuals for residential units and fitting out manuals for commercial spaces. The fitting out manual specifies the required standard for materials used in fitting out works and recommends green design guidelines for the tenants to follow when designing the leased premises.
