Energy Efficiency

The use of energy in general creates emissions, whether direct or indirect, that will lead to global warming and air quality deterioration. The core activities of CDL’s business are highly energy intensive, using both electricity from the grid and diesel. The extraction of fossil fuels causes depletion of natural resources and potential oil spills may threaten delicate ecosystems.

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.

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.

Stage in Project Lifecycle Energy Efficiency Focus Benefits
Design
Maximise use of natural lighting
and ventilation
Reduce electricity consumption
Use of solar energy for common areas
where applicable
Reduce reliance on the grid and lower carbon emissions
Use of energy efficient lightings in all common areas Reduce electricity use through energy efficient equipment or fittings
Energy efficient home appliances to be included in the units
Construction
Use of renewable energy where possible through installation of solar and Building Integrated Photovoltaic (BIPV) panels Reduce reliance on fossil fuel energy
Operation of Assets
Use of renewable energy where possible through installation of solar and Building Integrated Photovoltaic (BIPV) panels Reduce reliance on fossil fuel energy
Identify high energy usage installations to determine relevant initiatives, e.g. chiller upgrading or modernisation of lifts Reduce electricity consumption through energy efficient equipment
or fittings
Use of Energy Management System programme to optimise chiller efficiency and Building Management System to control key equipment in buildings Optimise key equipment’s efficiency and reduce energy use

 

CDL is committed to innovating, developing, and adopting energy efficient fittings and renewable energy solutions in our properties. This not only helps reduce electricity consumption, it also contributes to the industry’s know-how in green innovations for a low-carbon future.

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 in our managed buildings.

User behaviour has an impact on energy and resource consumption. As an asset owner, CDL has been actively engaging 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 our tenants 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.

Key Energy Initiatives in 2016

Energy Initiatives Buildings Savings
Chiller upgrading or improvement Republic Plaza, City House, Fuji Xerox Towers, Palais Renaissance 1,451,476 kWh/year, equivalent to
more than $270,000/year
Solar and BIPV panels 7 & 9 Tampines Grande, City Square Mall,
King’s Centre and Quayside Isle
193,886 kWh, equivalent to
almost $37,0006
Energy efficient lighting Fuji Xerox Towers, Manulife Centre,
King’s Centre
60,859 kWh/year, equivalent to
almost $12,000/year

As a result of our energy-saving initiatives, CDL achieved a reduction of 24% in total energy usage intensity in 2016 across all CDL commercial and industrial buildings against 2007 levels.

In 2015, CDL introduced targets to reduce energy use intensity across our core business operations in Singapore by 22% by 2020 and 25% by 2030 from 2007 levels. For the year in review, CDL achieved a 25% reduction in energy usage intensity, exceeding the original target set for 2030.

Energy Used in Key Subsidiaries

Similar to our reporting scope for GHG emissions of our headquarters’ operations, 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.
