To ask the Secretary of State for Work and Pensions how much was spent on energy efficiency measures for her Department's estate in each year from 2004 to 2009; what assessment has been made of the effectiveness of that expenditure; and what plans she has for future energy efficiency measures. (280547)

DWP receives fully serviced accommodation from its estates partner Telereal Trillium under a PFI arrangement. DWP does not, therefore, have direct responsibility for investing in energy saving measures. However, there is an agreed shared savings mechanism which provides Telereal Trillium with an incentive to invest in such measures.

The amounts invested by our PFI partner, in projects such as water-less urinals, tea-boiler timers, increased insulation, savawatt plugs and lighting improvements, are as follows:

The measures are piloted to validate the business case for their implementation before being introduced more widely. Their effectiveness is then further assessed on a financial basis, a year in arrears. DWP is involved in, and agrees, both of these processes.

Future plans involve the continued roll-out of automated meter reading (AMR) and the piloting of voltage optimisation equipment.

To ask the Secretary of State for Work and Pensions which official is responsible for the energy efficiency of her Department's estate. (280556)

The DWP finance director general acts as senior responsible office for sustainable development within DWP. Improving energy efficiency features within the targets for sustainable operations on the Government estate, and as such responsibility for day-to-day delivery rests with the commercial director.

To ask the Secretary of State for Work and Pensions what estimate she has made of the energy consumed per full-time equivalent member of staff in her Department in (a) 2006-07 and (b) 2007-08. (280968)

The following table gives details of energy consumption in offices in total, and per member of staff.

As there is no requirement within the targets for Sustainable Operations on the Government Estate to report energy consumption per full-time equivalent member of staff, we have used for consistency the same staffing figures as used to calculate the water reduction targets. These include an agreed allowance for on-site contractors/visitors.
