Actual measurement and numerical simulation were conducted in crawl space of detached houses, and the following points were clarified. 1. A house with high insulation performance of the floor insulation will have a lower temperature in the crawl space and higher humidity than a house with low. 2. Low temperature and high humidity becomes more noticeable in a house where it is difficult for outside air to flow into center of crawl space. 3. Outside air humidity has the largest effect on humidity of crawl space, followed by ventilation volume>thickness of floor insulation>cooling set temperature of room on 1st floor.

近年の住宅は,室内温熱環境の改善および冷暖房負荷の削減による省エネルギーを目的とし,高断熱・高気密化される傾向にある。れに伴い,室内で発生した水蒸気は屋外に排出されず,壁体内で結露を生じ建物の耐久性や断熱性能を低下させる危険性が高くなる。 本研究では,水分容量が大きく,吸放湿性能に優れたセルロースファイバー断熱材を使用した壁体において,実測と数値シミュレーションによる露性能評価を行い,その有用性を検討する。

The advanced theories on building physics applying THERB, such as thermal conduction, convection and radiation, for numerical simulation on the hygrothermal environment of buildings are exemplified and verified (to calculation accuracy. The followings are mentioned as the results; the need for calculation of combined heat and moisture transfer to analyze the hygrothermal environment, the importance of time-varying and nonlinearity of the coefficients of convection and radiation heat transfer in each point of buildings, the necessity of the detailed calculation of mutual radiation among the indoor surfaces in condition such as panel heating, the influences of the time shift of sunshine portion and the multiple reflection of transmitted solar radiation among the indoor surfaces.

In order to obtain the fundamental information for discussing residential energy saving strategies, long-term investigation of detail energy consumption and indoor climate Have been done in 2002 to 2003 for 80 dwellings, including detached houses and apartments, in six districts of Japan. The occupant's behavior and building thermal performance were also investigated. Energy consumption for each appliance was measured as much as possible. This paper reports the description of all houses measured and the end use structure of annual energy consumption. The main results are following; 1) In Hokkaido, Tohoku and Hokuriku districts, the annual energy consumption for many houses was more than 60GJ but such houses were very few in other districts. 2) The houses measured in Hokkaido and Hokuriku districts consumed almost the same amount of energy for space heating, cooling and mechanical ventilation as that for hot water supply. But in other districts, the share of energy consumption for hot water supply is the largest. 3) The annual energy consumption increased with the decrease in annual mean outdoor temperature. But the contribution rate is not large as 0.4.
