项目摘要

I. Measurement and comparison of thermal environment at the four test-houses constructed in the campus of Kagoshima University.(1) Test-house No.1 is 2x4, test-houses No.2 to No.4 are constructed with foam-core-panels (core:foam polystyrene, surfaces:OSB(oriented strand board).(2) Outdoor meteorological parameters, as well as indoor air temperature, surface temperature, globe temperature and relative humidity at four test-houses were measured for both active and passive modes.(3) Moisture content at various parts of the construction members were measured at the test-house No.2.(4) To examine thermal performance of a 2x4 house with roof insulation, the roof of the test-house No.1 was changed from 2x4 to foam-core-panel construction.(5) The sloped roof of the test-house No.4 was changed to flat roof in July 1992. The area of the flat roof was divided into two parts and one part was finished with steel on asphalt roofing, while the other was finished with FRP. The performance of the two kinds of waterproofing methods was compared by the condensation sensors.II. Field measurement of thermal environment of the house in south-western archipelago in Japan.(1) In 1991, two houses ( one is a wooden house with roof insulation and the other is a conventional wooden house in Kagoshima prefecture without insulation) in Nase city in Amami island was compared.(2) In 1992, a RC house and a wooden house in Kikai island was compared.(3) Thermal environment of several traditional houses in both of two islands were measured and compared with that of newly built houses.

I.鹿儿岛大学校园内建造的四个实验室热环境的测量和比较。(1)1号试验室为2x4，2号至4号试验室采用泡沫芯板（芯材：泡沫聚苯乙烯，表面：定向刨花板）建造。(2)在四个试验室分别测量了主动和被动模式下的室外气象参数以及室内空气温度、表面温度、地球仪温度和相对湿度。(3)在2号试验室测量了结构构件各部分的含水量。(4)为了检查具有屋顶隔热的2x4房屋的热性能，将1号测试房屋的屋顶从2x4改为泡沫芯板结构。(5)1992年7月，4号试验房的坡屋顶改为平屋顶。平屋顶的面积被分为两部分，一部分是用沥青屋顶上的钢完成的，而另一部分是用玻璃钢完成的。通过凝结水传感器对两种防水方法的防水性能进行了比较。日本西南列岛住宅热环境的现场测量。(1)1991年，在奄美大岛那世市的两个住宅（一个是屋顶隔热的木制住宅，另一个是鹿儿岛县没有隔热的传统木制住宅）进行了比较。(2)在1992年，一个钢筋混凝土房屋和木房子在Kikai岛进行了比较。(3)对两岛的几种传统住宅进行了热环境测量，并与新建住宅进行了比较。
