LONG-TERMED MEASUREMENT ON ENERGY CONSUMPTION AND THERMAL ENVIRONMENT FOR RESIDENTIAL BUILDINGS IN AKITA PREFECTURE(Environmental Engineering)

In order to consider the efficient residential energy conservation, measurements on energy consumption and thermal environment for four houses in Akita Prefecture have been conducted for two years. Annual and monthly energy consumption classified by end-use, and energy consumptions for some appliances in a typical summer and winter day were shown. In conclusion, the total energy consumption per household was 40-82 GJ/a, and that for space heating and hot water supply was to be 70%, showed a tendency with seasonal fluctuations, and varied house to house due to the differences of space heating form and usage pattern for each appliance.
