The Relationship Between Optical Properties of the Envelope Structure and Energy Consumption of the Building
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.
