摘要
通过分析拉萨城市住区四种典型布局模式下建筑群的太阳辐射得热量,得出朝向为南偏东15°平行行列式布局的建筑较有利于太阳能利用.因此,以平行行列式为研究对象,进一步分析了不同日照间距下建筑各层日照时间与能耗关系,研究发现:当建筑最小日照时间为2 h,2层及以上建筑能耗和建筑日照时间变化较小,当1层和2层建筑能耗占比较大(≤4层)时,推荐最小日照时间为2 h;当1层和2层建筑能耗占总能耗较小(≥5层)时,为节约用地面积,可采用1 h最小日照时间;并且给出了适宜的窗墙面积比,为拉萨未来发展的高密度建筑群设计提供参考依据.
In this paper,the solar radiation heat gain of buildings in Lhasa area is analyzed under the four layout modes of parallel determinant,transverse determinant,longitudinal determinant and mixed determinant.The layout mode of buildings with parallel determinant and 15°south by east is more favorable to solar energy utilization.In parallel determinant for object,further analyzing the different architectural layers under the sunshine spacing relationship between energy consumption and time,found that when building minimum sunshine time of 2 h,2 layer and smaller buildings energy consumption and sunshine time change,so when the layer 1 and layer 2 building energy consumption accounts for larger(≤4),recommended minimum sunshine time is 2 h.When the energy consumption of the first and second floors is small(≥5 floors),the minimum sunshine time of 1 h can be used to save the land area.In addition,the appropriate window and wall area ratio is recommended to provide a reference for the design of the rapidly developing high-density buildings in Lhasa.
