Smart metering

In 2010, we continued to operate smart meters at 55 of our top strategic locations, accounting for around 25% of our total floor space. These provide detailed monthly energy use reports, enabling us to identify inefficiencies, implement cost-effective reduction measures and achieve typical energy savings of 5-10% in each building.

Measures we are taking as part of our smart metering program 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 movement sensors to turn off equipment such as printers and copiers when offices are unoccupied.
  • Improving temperature controls on heating, ventilation and air-conditioning systems.
  • Fitting flow restrictors to hot water taps and upgrading boiler controls.

Improved metering also ensures that we are being charged accurately by our energy suppliers.

In 2011, we plan to install smart meters at additional locations focusing on newly acquired buildings and major refurbishments.

Energy-efficient lighting

We are installing energy-efficient light fittings with a target to complete installation in 80% of our buildings by the end of 2011. These fittings enable us to achieve typical savings of 5-10% in total energy consumption at each location. We have identified preferred suppliers in all regions, which our operating companies can use to buy and install energy-efficient light fittings.

Green buildings

We are integrating energy efficiency and other environmental considerations into our property acquisition process so that where possible any property we lease or purchase meets advanced standards such as Leadership in Energy and Environmental Design (LEED) and BRE Environment Assessment Method (BREEAM). We estimate that 7% of our total floor space is currently certified to such standards.

We have also developed a scorecard which is used to assess the environmental performance of new offices over 25,000 square feet which have not been certified to standards such as LEED or BREEAM. This covers six criteria: energy, carbon, water, materials/waste, travel and health and safety.

Efficient use of office space

We aim to make efficient use of office space and encourage flexible working where appropriate, enabling us to reduce our overall space requirements. This reduces costs and contributes to improved environmental performance.
