To clarify the hygrothermal behavior during winter of vertical edge insulation methods for foundation walls in moderate and humid climate region, temperature and relative humidity in 16 houses that include several insulation types and locations, have been measured. Results are as follows; 1) Temperature difference between south and north part in the crawl space is small even if under partial heating. 2) Absolute humidity in the crawl space is rather higher than that in 1F indoor air for 1 or 2 years from completion, and it tends to become the same level with that of 1F indoor air as times passed. 3) The condition of moisture in the crawl space is much influenced by the humidity in the just above 1F room.
