摘　　要：通过对现有有关围护结构光学参数与建筑能耗关系的文献进行系统分析,得到北半球建筑最佳窗墙比与纬度的关系,给出建筑南立面和北立面最佳窗墙比的参考范围;发现在炎热地区的夏季,有色玻璃、热致变色玻璃和Low-E玻璃的节能效果很好,且Low-E玻璃对寒冷地区的冬季也有较好的节能效果;在气候炎热地区,非透明围护结构使用反射隔热涂料会大大降低全年建筑能耗,寒冷地区采用上述措施后,全年建筑能耗的减小量并不十分明显,甚至有可能加大全年的建筑能耗.文章指出围护结构传热量与得热量是各种参数综合影响下的结果,应该对各种光学参数影响下的建筑节能进行多因素分析,并且在优化光学材料的节能性能的基础上降低建筑节能的成本.Through the systematic analysis of the existing literature on the relationship between the optical parameters of building envelope structure and building energy consumption,the relationship between the optimal window wall ratio and latitude of buildings in the northern hemisphere is obtained,and the reference range of the optimal window wall ratio of buildings in the south and north facades is given.It is found that the energy-saving effect of colored glass,thermochromic glass and Low-E glass is very good in hot summer,and Low-E glass also has good energy-saving effect in cold winter.In hot climate areas,the use of reflective thermal insulation coating for non-transparent envelope will greatly reduce the annual building energy consumption.In cold areas,the reduction of annual building energy consumption is not very obvious,and may even increase the annual building energy consumption.It is also pointed out that the heat transfer and heat gain of building envelope structure are the results of the comprehensive influence of various parameters.The multi-factor analysis of building energy saving under the influence of various optical parameters should be carried out,and the cost of building energy saving should be reduced on the basis of optimizing the energy saving performance of optical materials.
