用途別エネルギー消費量の年合計および月変動 : 関東地域における住宅のエネルギー消費量に関する調査研究  [in Japanese] ANNUAL SUM AND MONTHLY FLUCTUATION OF ENERGY CONSUMPTION FOR EACH USAGE : Study on energy consumption in houses in Kanto district  [in Japanese]

The energy consumption in Japanese houses is increasing rapidly, and it's effective saving method and minute investigations are needed. We carried out detailed load survey on actual houses in Kanto district, 9 detached houses and 5 apartment houses. Electricity was measured for air conditioning, hot water, and main each house appliances. Usage estimation was applied for measured gas volume. The main usage in total annual energy consumption is air-conditioning and hot-water. On the analysis using correlation and covariance, we found that energy consumption's difference between houses and seasonal fluctuations are mainly caused by air-conditioning, hot-water and lighting.
