In order to obtain the fundamental information for discussing residential energy saving strategies, long-term investigation of detail energy consumption and indoor climate Have been done in 2002 to 2003 for 80 dwellings, including detached houses and apartments, in six districts of Japan. The occupant's behavior and building thermal performance were also investigated. Energy consumption for each appliance was measured as much as possible. This paper reports the description of all houses measured and the end use structure of annual energy consumption. The main results are following; 1) In Hokkaido, Tohoku and Hokuriku districts, the annual energy consumption for many houses was more than 60GJ but such houses were very few in other districts. 2) The houses measured in Hokkaido and Hokuriku districts consumed almost the same amount of energy for space heating, cooling and mechanical ventilation as that for hot water supply. But in other districts, the share of energy consumption for hot water supply is the largest. 3) The annual energy consumption increased with the decrease in annual mean outdoor temperature. But the contribution rate is not large as 0.4.
