To ask the Secretary of State for Energy and Climate Change how much was spent on energy efficiency measures for his Department’s and its predecessor’s estate in each year from 2004 to 2009; what assessment has been made of the effectiveness of that expenditure; and what plans he has for future energy efficiency measures.

In 2007-08, DEFRA installed a powerPerfector in 3 Whitehall Place. The unit, installation and delivery costs were £70,878.35 (including VAT). Overall energy consumption reduced by 8.66 per cent. from the installation date (March 2008) to May 2009.

Since its inception in October 2008, DECC, working with Carbon Trust and others, has identified and started to implement a range of energy efficiency measures at its HQ in 3 Whitehall Place. These include changes to lighting, heating and cooling controls, through optimisation of the building management system. Initial estimates suggest that investment in this work could be recovered in little over one year due to projected energy savings.
