Abstract:

A series of questionnaire survey on condition of winter heating of residential building and field measure of typical cases were launched in Hangzhou. The characteristics of winter energy utilization in Hangzhou were found out through analyzed the survey data. In addition to air conditioning ,other heating devices are also important in Hangzhou which is a typical city in hot summer and cold winter zone. Moreover, as high as 98% dwelling houses have air-conditions, but in the winter, the number of dwelling house did not open air-conditioning account for about 1/3~1/2.
