| Outline of Final Research Achievements |
The following three points were the main research items in the development of high performance passive ventilation house for the northern region: 1) evaluation of basic performance and living environment in this house, 2) construction of the design tool for passive ventilation and whole-room heating, 3) examination of building and equipment specifications and community heating suitable for solar and biomass heat utilization types. Specifically, in the demonstration experiment, we collected the basic data, checked the thermal comfort and measured the indoor air quality. The characteristics of air circulation and whole-room heating peculiar to passive ventilation were clarified. On the other hand, in the numerical simulation, we examined the high performance passive ventilation house and house group suitable for solar and biomass heat utilization types in various ways. The effects of single house and its assembly were estimated according to the area and household composition.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では主にパッシブ換気住宅の高度化に着目し，これは北海道に限らず近隣の極東ロシアや中国北部に対しても大きなインパクトを与えることになる．特に超高性能化は低温未利用エネルギーの活用に直結し，再生可能エネルギーの利用価値を一層向上させることになる．更に欧米諸国に比べて低いとされる断熱水準の底上げを後押しし，北方圏を対象としたネット・ゼロ・エネルギー・ハウスや無暖冷房住宅の開発に役立つと考えられ，独創的かつ意義のある研究と言える．
