The core activities of CDL’s business are energy intensive and electricity constitutes a significant proportion of our operating expenditure. Improvements in energy efficiency will thus enable us to reduce cost and improve our operational efficiency. Integrating energy efficiency considerations into the design and construction of our assets can also help to reduce the energy usage (and electricity costs) of our customers, tenants, and residents.
Lifecycle Approach of Energy Management
In 2014, CDL became the first developer in Singapore to achieve the ISO 50001 Energy Management System (EnMS) certification for the provision of property and facilities management services.
We have since continued to set energy reduction target for every investment properties we manage, whilst working towards optimising energy performance at every stage of a building’s lifecycle.
Initiatives to maximise energy efficiency are applied differently across our key business units and at different stages in the building’s lifecycle. Each business unit has its own specific guidelines that detail the strategic initiatives, performance standards, and specific requirements relating to energy efficiency and climate change mitigation measures. These guidelines are to be considered in the design, construction and operation of the assets.

Energy Reduction Initiatives
Since 2004, CDL has retrofitted all our existing commercial and industrial buildings through initiatives such as chiller plants upgrading, introduction of motion sensors to reduce lighting consumption, installation of energy-efficient lighting, and recladding of facades to reduce solar heat gain. On average, these efforts have yielded an estimated annual energy savings of around 17.6 million kWh and an equivalent of more than $4.01 million in 2018.
We remain committed to further reducing our energy consumption and improving our energy efficiency, through a number of key initiatives in 2018.
Key Energy Reduction Initiatives in 2018
|Energy Reduction Initiatives||Buildings||Savings|
|Lift Upgrading||Republic Plaza||555,700 kWh/year, equivalent to almost $127,102/year|
|Air conditioning upgrading or improvement||Republic Plaza, City House, Fuji Xerox Towers, Central Mall (Office Tower)||185,187 kWh/year, equivalent to almost $42,357/year|
|Energy efficient lighting||City House, Palais Renaissance, City Square Mall, Tagore 23||25,928 kWh/year, equivalent to almost $5,930/year|
User behaviour has an impact on energy and resource consumption. As an asset owner, CDL actively engages our tenants on the importance of energy conservation. In partnership with Tuas Power, an Automated Meter Reading portal was introduced in 2014 for our tenants to monitor their electricity use on a near real-time basis. This empowers them to better track their energy consumption, as what gets measured, gets managed. In addition, incentives from both Tuas Power and CDL are provided to tenants who achieve substantial reductions in energy consumption.
Energy Reduction Target and Performance
Electricity consumption contributes a significant proportion towards our operational expenditures, and further impacts the total amount of carbon emissions released through our business activities. Hence, it is pertinent that CDL raises energy efficiency standards in a cost-effective manner to bring about reductions in carbon emissions and energy intensities.
As part of our ISO 14001 Environmental Management System objectives, and push for continual improvements in our energy performance, CDL set targets to reduce energy usage intensity2 by 35% from 2007 levels, by 2030. In 2018, we achieved a reduction of 27% and will be monitoring energy performance closely towards our 2030 targets.
Subsidiaries’ Energy Usage
Similar to our reporting scope for GHG emissions, CDL also reports on the energy data of our subsidiaries. The tracking and reporting of our subsidiaries’ energy data not only ensures greater disclosure and accountability, but also enables the Group to better manage energy usage as a whole. Given CDL’s strong commitment to environmental protection and energy conservation, the behaviours and practices of our subsidiaries are also of importance to us.
The following chart shows the energy usage of CDL and six key subsidiaries, namely CBM, CDLHT, CSO, Le Grove, Tower Club and M&C.
