Office energy efficiency
In 2008, we launched a global metering project to bring energy savings by cutting waste. We are investing £750,000 to install meters in 100 of our largest sites globally (representing 65% of our property portfolio by floor space). These will centrally monitor energy use, enabling us to make savings of between 10% and 15%. Improved metering will also ensure that we are being charged accurately by our energy suppliers.
The metering project will help us determine the most efficient and cost-effective ways of achieving energy savings. These may include:
- Fitting timer switches to ensure lights are not left on overnight.
- Adding movement and daylight sensors to ensure lights are only on when needed.
- Installing energy-efficient lamps.
- Fitting flow restrictors to hot water taps.
- Fitting power management controls to vending machines and refrigerators.
- Improving air-conditioning controls.
- Installing building management systems that monitor and control ventilation and lighting.
In 2008, we identified preferred suppliers in all regions, which our operating companies can use to buy and install low-energy light fittings. We will begin an installation program for low-energy fittings in 2009.
Where possible, we aim to ensure that any properties we purchase meet advanced environmental standards such as Leadership in Energy and Environmental Design (LEED) and BRE Environment Assessment Method (BREEAM). For example, a new purpose-built facility for nine of our companies in Singapore is being designed to the Green Mark Scheme Gold Standard, which is equivalent to LEED. George Patterson Y&R, Brisbane relocated to a new building rated 5 Star under the Australia Green Buildings Rated System and O&M implemented LEED initiatives in design and construction of five new buildings. O&M Worldwide’s headquarters in New York, designed and built for LEED certification, has been selected for the Green Building of America Award-winning Project, from 2,500 buildings nominated as part of the Real Estate & Construction Review magazine’s 2009 Green Success Stories. Grey New York will move to a LEED-Certified building in late 2009.
