【 摘 要 】

Nepal has sub-tropical to cold regions due to large altitude difference. The traditional houses are well adapted to the local climate with the use of local building materials. However, traditional practice has been diminished by more introduction of the artificial building materials, modern design and new technology. Under this circumstance, some strong policies based on a field research to sustain the traditional architecture with some rational modern metamorphosis is necessary. For this reason, we investigated the wintry indoor thermal environment of traditional houses in three climatic regions of Nepal. We measured the indoor thermal environment all together nine houses in cold, temperate and sub-tropical regions during the winter in December 2016. The houses were found to be eighty percent of the time below 11°C, 16°C and 22°C in cold, temperate and sub-tropical regions, respectively. This result is well attributed to the regional climatic difference and the thermal characteristics of building materials used. The traditional houses surveyed are considered to be adapted to the climates because of the local availability of building materials.
