Abstract
Temperature and humidity in the crawl spaces of house have great influences to durability of the house. Therefore temperature and humidity in the crawl spaces have to be studied the gross crawl spaces including ground soil. We investigate ventilation and hygrothermal characteristics of confined crawl spaces without soil cover. Computer simulation based on simultaneous heat and moisture transfer for confined gross crawl spaces including ground soil and multi room temperature and humidity, together with ventilation balance eluations reveals that soil cover in summer makes higher humidity of crawl spaces than no soil coves due to the moisture reduction effect by absorption of ground soil in summer.
