Related surveys were carried out in summer of 1992 and winter of 1993 on energy consumption, indoor climate and life style in residential buildings. Samples of the surveys consist of three types of residential buildings, i.e., detached houses, condominiums and apartments. They are located in eight city areas of broad climatic conditions. Life style factors were measured with questionnaires, indoor temperature was measured in each living room for at least a week with originally designed automatic temperature recorder, and energy consumption data other than that of kerosene was obtained from supply companies. The data of kerosene was obtained in the questionnaires. In this paper, actual energy consumption for difference uses in thirty-nine resi-dential building groups are estimated with the same procedure. Determinant factors of energy consumption for heating, cooling,domestic hot water, lighting etc. and cooking are analyzed, and as a result estimation formulas are obtained.
