摘　　要：为了解拉萨传统民居室内热环境现状,进一步为当地民居冬季室内热环境的改善提供依据,对拉萨某传统民居的冬季室外气象环境和室内热环境进行了长期测试与结果分析。并根据当地民用建筑节能设计标准对室内热环境进行评价,提出不舒适度日数(UCDD12)作为评价室内温度与最低舒适温度差距的量化指标。结果表明:该传统民居未生火炉的人员活动房间室内温度波动较小,但不舒适度日数过大,原因是室内热源不足、围护结构保温性能较差,应利用当地丰富且稳定的太阳能资源及优化围护结构的热工性能设计以改善室内热环境。In order to investigate the current status about indoor thermal environment of traditional residential buildings in Lhasa,further provide a basis for improving the indoor thermal environment in winter,a long-term test and result analysis were carried out on the winter outdoor meteorological environment and indoor thermal environment of a local traditional residential building. The indoor thermal environment is evaluated according to the local civil building energy-saving design standards,and the number of uncomfortable degree days( UCDD12) is proposed as a quantitative index to evaluate the difference between the indoor temperature and the minimum comfortable temperature. The results show that the indoor temperature fluctuation of the personnel activity room without a stove is small,but the number of uncomfortable degree days is too large. The reason is that the indoor heat source is insufficient and the insulation performance of the enclosure structure is poor. The local abundant and stable solar energy resources should be used and the thermal performance design of the enclosure structure should be optimized to improve the indoor thermal environment.
