§ Mr. Ernie Rossasked the Secretary of State for Energy if he will estimate the amount of extra heat energy required to maintain a house in Dundee at a given temperature compared with an identical house in Glasgow taking into account differences in air temperature, wind exposure, rain and sunshine.
§ Mr. John MooreAlthough heat requirements vary substantially it is estimated that a typical three-bedroomed house in Dundee, maintained at a given comfort temperature, requires about one-eighth—12.5 per cent.—more heat than the same house in Glasgow, similarly sited and at the same temperature, after taking account of differences in temperature, wind and sunshine.
