The indoor thermal environment, air quality and occupant behavior in well-insulated and airtight houses in and around Tohoku District have been investigated through questionnaire and field measurements since 1993. It was showed by the authors that the houses provide a comfortable indoor environment and also has a good influence on occupant' health, but there are some problems related to dry feeling. This paper describes i)analysis on relationship between dry feeling and residential factors by a multi-variate analysis method and ii)investigation results of a questionnaire on moisture sensation and the measurement of indoor temperature and humidity, which were performed in 60 houses of Tohoku District of Japan during February of 1996. The well-insulated and airtight houses investigated have central heating and mechanical ventilation system for the entire house. These analysis on the relationship between dry feeling and indoor environment shows that the dry feeling doesn't depend on indoor relative humidity. Namely, the occupants felt dryness in the houses with relative humidities of 40 to 70%. It is suggested that the dry feeling comes from not only relative humidity but also indoor air quality. Its problem should be investigated in future.
