拉萨被动式太阳能建筑供暖潜力分析
Heating potential of passive solar building in Lhasa
摘要：
对拉萨2栋被动式太阳能建筑冬季室内热环境进行了现场测试，结果显示室温能够满足要求。以某实际工程为例，对被动式太阳能建筑的热特性进行了分析，研究了外墙保温性能、外窗热工性能及建筑窗墙面积比对被动式太阳能建筑的影响，分析了最冷月被动式太阳能供暖建筑的室内热环境。提出被动式太阳能供暖的可行性、潜力和热工设计要素。指出拉萨地区能实现全被动供暖，可大大降低冬季供暖能耗。
Abstract：
Tests the indoor thermal environment in two passive solar buildings in Lhasa in winter, of which the results show that the indoor temperature is satisfactory. With a project, analyses the thermal characteristics of the passive solar building, discusses the influences of thermal insulation performance of exterior walls, thermal performance of exterior windows and area ratio of window to wall on the passive solar building, and analyses indoor thermal environment in the passive solar heating building in the coldest month. Advances the feasibility, potential and thermal design elements of passive solar heatings. Points out that all-passive heating in buildings can be achieved in Lhasa and the heating energy consumption in winter can be greatly reduced.
