The purpose of this study is to examine the actual conditions of the energy consumptions of various purposes in the houses in Niigata area. The data showed in this paper is measured continuously from November 2002 to March 2004. We have analyzed the results as follows. (1)The average of annual energy consumptions amount is 70.3GJ. Although the annual amount of energy consumptions varies in each house, the amount of per floor area decreases such differences. (2)Total rate of air-conditioning of four seasons is 77.6% of the whole amount of energy consumptions, which includes 41% of the heating system and 35% of hot-water supply in winter. (3)Seasonal amount of energy consumption decrease in spring and autumn, and increase in winter. This result shows the elements which affect seasonal change of the amount of energy consumption are mainly air-conditioning and hot-water supply. (4)A change in the day of the amount of energy consumption varies in the existence of the use of the midnight electric power. (5)Regarding the change of consumptions of the day, use of air-conditioning and hot-water supply is longer in winter compared to summer, and their peak of energy consumption increases in winter. There is no remarkable difference in energy consumption of other uses in summer and winter.
