§ Mr. Lawsonasked the Secretary of State for the Environment, pursuant to the Secretary of State for Energy's statement on energy conservation on 12th December 1977, what is the present average room temperature in Government buildings ; and what would be the value of the energy saved by each degree centigrade reduction in that temperature.
§ Mr. Marks:The standard of heating for occupied Government offices generally is 18.5°C and every effort is made to keep to this standard. A reduction of 1 °C in room temperature in Government buildings would save an estimated £1.5 million per annum in energy costs.
