§ Mr. Ernie Rossasked the Secretary of State for Scotland if he has calculated the heat loss in any one hour from a room 15 feetx12½feetx8feet heated to 65 where a freeway acoustic ventilator has been fitted under the Noise Insulation (Scotland) Regulation 1975, due to trunk road improvements.
§ Mr. AncramNo. Heat losses or gains likely to result from the fitting of complementary ventilators and secondary glazing will depend on a number of variable factors. They are not a consideration relevant to installation in terms of the Noise Insulation (Scotland) Regulations 1975.
§ Mr. Ernie Rossasked the Secretary of State for Scotland if he will make available additional assistance to householders affected by increased energy costs as a result of the decision to fit freeway acoustic ventilators under the Noise Insulation (Scotland) Regulation 1975.
§ Mr. AncramNo. The measures offered under the terms of the Noise Insulation (Scotland) Regulations 1975 are designed to insulate rooms against traffic noise while permitting adequate ventilation. It is for the residents to decide when to use the ventilators, and so energy use may vary from household to household and according to the weather.

§ Mr. Ernie Rossasked the Secretary of State for Scotland what savings are likely to be made by the decision to fit freeway acoustic ventilators to houses in Dundee, under the Noise Insulation (Scotland) Regulation 1975 rather than fitting double glazing.
§ Mr. AncramNone. Under the Noise Insulation (Scotland) Regulations 1975 ventilator units are a prescribed complementary measure where either double or secondary glazing is installed.
