| Abstract: | Solar radiation has great effects on heating and cooling load of buildings,and the application of sun-shade structure is an important method to improve the building energy consumption.The energy consumption unit building area of the same building was used as index for measuring the effect of sun-shade.Combined with the climatic characteristics of Chongqing,the effect of Low-E glass and the sun-shade performance of horizontal sunshade board on building energy consumption was analyzed.And the optimal configuration dimensions of Low-E glass and the horizontal sunshade board for Chongqing were recommended on the basis of different requirements for building energy saving in winter and in summer. |

| Keywords: | Low-E glass horizontal sunshade shading coefficient building energy consumption |
