To ask the Secretary of State for Defence how much was spent on energy efficiency measures for his Department'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. (280541)

Use of energy efficiency measures, such as insulation, double glazing and cladding, form an integral element of the routine maintenance and management of the estate. A breakdown of the specific investment since 2004 to date is not held centrally and could be provided only at disproportionate cost.

However, in addition to such routine investment, over the last two years this Department has invested some £8.9 million in 51 projects. It is estimated that these projects will result in financial savings of £2.8 million and emission reductions of 21,600 tonnes of CO₂. The projects include Combined Heat and Power, biomass boilers, ground source heat pumps, building management systems and lighting projects.

In order to meet the targets placed on all Government Departments, MOD continues to identify opportunities to make further energy savings on its estate. Work includes undertaking energy audits on site, installing SMART meters and wherever possible achieving excellent rating in the Defence Related Environmental Assessment Methodology or the British Research Establishment Environmental Assessment Methodology for new builds and major refurbishments.
