In Japan, from the viewpoint of energy conservation, residential houses are more highly insulated and airtight. Authors already showed an outline of the database of detached houses in Nagano City area. This paper, which is a series of study on application of the database, describes the trend of airtightness of well-insulated and airtight houses in Nagano City area, its characteristics of each building construction, the relationship between airtightness and indoor thermal environment. These results are shown as follows: (1) For the past ten years, the degree of airtightness of residential houses constructed in Nagano City area has greatly increased. The percentage of a house with an envelope leakage area less than 2.0cm^2/m^2 of the floor area is 77%. (2) There are some features in an envelope leakage of each building construction. (3) Airtightness of residential houses affect temperature difference between 5cm and 1.5m above floor level, and radiant temperature difference. In a border of 2.0cm^2/m^2, there is a significant difference into its relationship with significant level of 5.0%.
