HC Deb 16 July 1980 vol 988 c601W
Mr. Hannam

asked the Secretary of State for the Environment how the proposals for new building regulations for domestic buildings propose to utilise the window for energy conservation purposes.

Mr. Geoffrey Finsberg

Recent consultations included a proposal to rewrite energy conservation regulations for dwellings in a form which encourages designers to consider the advantages of multiple glazing and to take into account solar gain.
