摘　　要：针对拉萨地区某一经过被动太阳能改造典型藏族单层民居,分别在冬、夏季测试了室外气温、太阳辐射强度和不同房间的室内温度。分析测试结果后发现:在拉萨的典型天气条件下(冬季室外平均气温约为0℃,日照时间内太阳总辐射平均强度约为0.45kW/m^2),采用大面积南向单玻外窗的被动太阳房室内最低温度与其他房间接近,平均温度和最高温度分别比其他房间提高约3℃和7℃;而被动太阳房在夏季并未出现明显的过热现象。针对该地区被传统民居室内温度整体偏低、被动太阳房室内温度波动大的现状,提出了加强建筑保温和蓄热性能的改造建议。Solar radiation intensity, indoor and outdoor temperature were tested for a single story Tibet an traditional dwelling building of Lhasa city in winter and summer, respectively. The results show that： under typical winter weather condition,average indoor temperature of passive solar house, which fit on big southern window with single layer glass, is about 3 ℃ and 7 ℃ higher than that of normal room, respectively, although valley values are similar in all rooms; Obvious overheat was not found in passive solar house in summer. Technical suggestions for increasing building＇s heat insulation and thermal storage capability were provided, as the indoor temperature of traditional dwelling was wholly low, and that of passive solar house fluctuated sharply.
