Authors have already showed the outline of the databese on indoor thermal environment of detached houses in Nagano Prefecture. This paper, which is a series of study on application of the databese, firstly describes the relationship between a housing attribute and a shelter performance of detached houses. Secondly, energy consurrmtion of ninety-seven well-insulated and airtight houses is discussed. Thirdly, annual indoor environment and energy consumption for space heating in five typical houses using various heat sources, is discussed. These results are shown as follows: (1) The percentage of a house with an envelope leakage area less than 5.0cm^2/m^2 of the floor area is 90%. (2) Energy consumption for space heating in ninety-seven houses is changing between 8.6 and 77.1 GJ/year. The energy consumption of well-insulated and airtight house is more than the mean value of ordinary existing house in Hokuriku District. (3) It is seemed that the energy consumption for space heating is greatly influenced by an occupants' behavior.
