Departmental Energy Gregory Barker To ask the Secretary of State for Northern Ireland how much (a) electricity and (b) gas was used (i) on his Department's estate and (ii) by his Department's agencies in each year from 2004-05 to 2008-09. Mr. Woodward I refer the hon. Member to the answer I gave to the hon. Member for Tunbridge Wells (Greg Clark) on 5 May 2009, Official Report, column 10W. Gregory Barker To ask the Secretary of State for Northern Ireland 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. Mr. Woodward My Department does not separately record all expenditure on energy efficiency measures, therefore this information could be provided only at disproportionate cost. We have however taken a number of steps in our various buildings to improve energy efficiency, including; increasing staff awareness, ‘switch off campaigns’, upgrading building management systems, adoption of a ‘Green IT’ strategy, investment in generating energy from renewable sources, purchase of green electricity, installation of a CHP system, and fitting out some buildings to encompass energy efficiency measures as defined in the 2006 Building Regulations Technical Booklet Part F—Conservation of Fuel and Power (NT). Future energy efficiency measures will be considered as part of our overall accommodation strategy.
