项目摘要

The point of applying traditional passive cooling method to modern houses in seasonally hot and humid area is shown through the comarison of indoor thermal environments between traditional vernarcular houses and modern houses referring the difference of materials, structures, designs, and details. The results of this research are as follows:1. The words relaiting to passive cooling methods were selected from vocablaries of tradi-tional vernacular houses in Japan and classified as to the distinction of location in the houses or the region in Japan.2. The questionnaire to survey the attitude of designers to passive cooling was conducted gathering the examples of passive design. The survey showed the necessity of exact estimation of passive cooling effect.3. Several kinds of traditional passive cooling methods vanished from modern houses were confirmed their cooling effects in ten traditional vernacular houses in Kyushu and Okinawa Islands.4. A modern passive cooling houses in Naha was scrutinized its cooling effects as to the followings; natural ventilation, heat exhaustion, double enveloped roof, vegetation, and water sprinkled roof.5. An experimental house, completely electrified, in Fukuoka was measured to examine the cooling and energy saving effects of the following items; air-conditioning systems including floor-heating/-cooling, earth contact floors, and outside heat insulation of its basement.6. A test house, well heat insulated and air tightened, in Tokuyama was measured to examine the effects as to the following items; pair-glazed windows, plastic window sashes, an attached underground room, cooling tubes, and a central heat-pump system for air-contioning.

通过传统民居与现代住宅室内热环境的比较，从材料、结构、设计、细节等方面的差异，说明传统被动式制冷方法在季节性湿热地区现代住宅中应用的要点。本研究的结果如下： 1．与被动冷却方法相关的词汇选自日本传统民居的词汇，并根据房屋中的位置或日本地区的区别进行分类。2．通过收集被动设计的例子，进行了问卷调查，以调查设计者对被动冷却的态度。调查结果表明，准确估算被动冷却效果的必要性； 3．现代住宅中消失的几种传统被动制冷方式，在九州和冲绳群岛的10座传统民居中证实了其制冷效果。 4．那霸的一座现代化被动式冷却房的冷却效果如下：自然通风、排热、双层围护屋顶、植被、洒水屋顶。5．对福冈一座完全电气化的实验房屋进行了测量，以检查以下项目的冷却和节能效果；空调系统，包括地暖/制冷、接地地板以及地下室的外部隔热。6．对位于德山的一座隔热和气密性良好的试验室进行了测量，以检查以下项目的影响；双层玻璃窗、塑料窗扇、附属的地下房间、冷却管和用于空调的中央热泵系统。
