西藏藏东南地区民居建筑热环境现状分析

Analysis on Thermal Environment Current Situation of Residential Buildings in the South-Eastern of Tibet

随着社会经济的发展,西藏藏东南地区传统民居建筑的石木结构逐渐被钢筋混凝土及砌块所取代。现代建筑材料与传统建筑材料对西藏藏东南地区的民居建筑热环境到底有何影响?本文通过实际调查,在西藏林芝县八一镇觉木村选取两家代表性的民居建筑,一座是采用传统建筑材料(木材、块石、土坯砖、泥浆)建造的塔吉家,一座是采用现代建筑材料(砌块、钢筋混凝土、石灰)建造的江村家,分别对两家进行了温度、湿度、照度以及风速的测定。通过对试验数据的分析得出,在西藏藏东南地区,传统建筑材料在隔热保温性能方面优于现代建筑材料。

With the development of social economy,in the south-eastern of Tibet,the stone and timber structure was gradually replaced by the reinforced concrete and masonry in traditional residential buildings.How did modern building materials and traditional building materials affect the thermal environment of the residential buildings？ According to practical investigation,two representative residential buildings were selected to analyze temperature,humidity,light intensity and wind speed in Juemu village Bayi town Linzhi area of Tibet.The house of TaJie is built by traditional building materials（wood,stone,adobe brick,mud）,and the house of JiangCun is built by modern building materials（block,reinforced concrete,lime）.Based on the test data analysis,the traditional building material in the heat insulation and thermal insulation is better than the modern building materials in the south-eastern of Tibet.
