§ Mr. Don FosterTo ask the Secretary of State for the Environment, Transport and the Regions what estimate he has made of the number of new office buildings built in each year between 1990 and 1999 which had air conditioning. [142824]
§ Mr. MeacherThe Department has not estimated the specific figures centrally. However, the Building Research Establishment estimates the office space built each year between 1990 and 1999 with some air conditioning as follows:
million Year M2 new build offices with some air conditioning 1990 2.0 1991 1.3 1992 0.9 1993 0.5 1994 0.6 1995 0.9 1996 1.1 1997 2.3 1998 2.8 1999 1.4 The approximate amount of office space built with some air conditioning as a proportion of all new office space built in each of the above years is 50 per cent.
