Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what steps he has taken to insulate his departmental estate in order to improve energy efficiency; and if he will make a statement.

In 70 Whitehall external walls and roof spaces are insulated; all new pipework has thermal insulation; and, windows on the east and west elevations having secondary glazing. The building also benefits from heat recovery in the plant rooms to heat some hot water and a bore hole that draws water from an aquifer to provide sustainable free cooling in summer.

Cabinet Office also incorporates lighting control mechanisms via presence detection and daylight sensors into its core buildings.
