Evaluation on energy efficiency of windows in different climate zones of China

In this paper several kinds of window shading are introduced and compared. In addition, the potential of energy efficiency of exterior shading and three representative windows in three typical cities of China are analyzed and compared using eQUEST software. The objective of this paper is to analyze the influence of window shading in different climate zones of China through simulation. The result shows that in freezing climate zone it is appropriate to use the low-e windows with small U-value.
