| Outline of Final Research Achievements |
In order to prevent microbial contamination from the crawl space with vertical edge insulation system, the Sensible Heat Exchange type solar heated Air Collection (SHE-SAC) system are developed, and evaluated this system installed in a real house. Moreover, the SHE-SAC system module was incorporated into the Heat, Air and moisture transfer analysis program coupled to the advection to perform parameter analysis, and the risks caused by high moisture environment in the crawl space causing microbial contamination was examined.
When using the SHE-SAC system in Sapporo's climatic conditions, it became clear that there is an effect on the relative humidity making stable to moderate in the crawl space even without sensible heat exchanger if the appropriate device capacity is secured. In addition, it was found that Region south of Morioka and Sendai needed to use a sensible heat exchanger according to the local weather conditions, especially relative humidity.

| Academic Significance and Societal Importance of the Research Achievements |
基礎断熱工法は，住宅の気密性能や耐久性向上など多くの利点を有する一方，高湿な期間が比較的長い温暖地では梅雨時期から夏期にかけて微生物汚染が生じやすい。微生物増殖抑制には，材料表面を効率的に乾燥させるしくみが求められるが，できるだけエネルギーを使わないシステムが望ましい。居住者対応に依存せず，エネルギー自立型の熱交換型太陽熱集熱システムを応用することより，床下の微生物汚染のリスクを減少させるとともに，居住者の健康維持に寄与することができる。
