The Department of Energy and Climate Change has been working with Carbon Trust to develop and deliver a wide-reaching energy reduction and carbon management programme focusing on our London HQ. A number of significant changes have already been made, with visible reductions in energy consumption. Many of the changes relate to the Building Management System, to optimise the operation of the heating, ventilation and air conditioning (HVAC) plant, by adjusting time schedules and rationalising temperature set points. We are also upgrading lighting to energy efficient systems, replacing tungsten halogen bulbs with LEDs, and installing and enabling daylight and occupancy sensing. We have installed eCubes to fridges, with potential for 15-20 per cent. energy savings.
In its Low Carbon Transition Plan, published on 15 July, DECC committed to a 10 per cent. reduction in its carbon emissions in this financial year, with more to come in 2010 and beyond.
In 2008, DEFRA installed a powerPerfector in 3 Whitehall Place, reducing energy consumption by 8.66 per cent. from the installation date to May 2009.
DECC is also promoting energy efficiency amongst its staff, senior managers and Ministers through a number of behaviour change activities, including encouraging use of the stairs, turning off electrical equipment when not in use, and reducing use of printers and photocopiers.
