摘要
为研究多因素对不同热工分区办公建筑总负荷指标的综合影响,在分析了单一因素对建筑总负荷指标影响规律的基础上,采用层次分析法对分别位于哈尔滨、兰州、重庆、广州的办公建筑负荷指标进行了评价。得到了窗户传热系数Kw、玻璃遮阳系数S_c、窗墙比R在不同热工分区办公建筑总负荷指标影响因素中的权重值,并对此进行了一致性检验。结果表明:对于严寒地区的哈尔滨和寒冷地区的兰州节能建筑,各因素重要程度为R>K_w>S_c;对于夏热冬冷地区的重庆和夏热冬暖地区的广州节能建筑,各因素重要程度为S_c>R>K_w。在建筑结构优化设计中应根据各热工分区负荷影响因素的比重不同进行优先控制相应因素。
The building total load index of the office buildings in Harbin,Lanzhou,Chongqing and Guangzhou were assessed by the analytical hierarchy process based on the effect of single factor on the building total load index to study the synthetic effects of several factors on the total load index of the office buildings in four climate zones.The weights of varied indexes of window heat transfer coefficient,glass sunshade coefficient and window-wall ratio were determined by the analytical hierarchy process.And the consistency of the weight of index was checked ultimately.The results indicated that the importance of the three factors for the total load index of the office buildings in Harbin and Lanzhou was R〉Kw〉Sc,while the importance of the three factors for the total load index of the office buildings in Chongqing and Guangzhou was S_cRK_w.In the optimum design of building structure,the crucial factors should becontrolled preferentially for a building in different climate zones.
