Abstract
In this paper, the relationship between household energy comsumption for air-conditioning in summer and constitution of family in urban area was analyzed by using the model developed in the authors' previous study (1999). This model calculates the distributions of air-conditioning load for a typical household in urban area. Based on this model, a case study for different types of constitutions of families, which were assumed with regard to the numbers of families, was performed in case of Fukuoka City area. For each category of the family constiturion, the working pattern of airconditioners was established referring to the reports by EDMC (The Energy Data and Modeling Center), etc. Then, the influences by the changes of the family constitutions, which were assumed to be increasing in ratio of one-person housholds and working women, were estimated spatially and discussed quantitatively for Fukuoka City area. As a result of this analysis, the air-conditioning energy load of the category of one-person family increased and the load of the fourperson category decreased with this assumed change of family constitutions
