2)电致变色玻璃可以大大降低建筑制冷能耗,但是对于制热能耗,很可能会出现能耗增加的情况。所以,对于寒冷和严寒地区,由于采暖能耗比较大,如果选择电致变色玻璃,一定 要慎重选择控制方式。

[4]E.S. Lee*, A. Tavil. Energy and visual comfort performance of electrochromic windows with overhangs[J] Building and Environment 2005.Energy performance of LOW-E glazing and electrochromic glazing were compared, while different control way ofelectrochromic glazing impaction on building energy were studied. It was shown that electrochromic glazing had very good energy efficiency compared with LOW-E glazing, the minimum energy reduction is 10%,and control way of electrochromic glazing had very little impaction on cooling energy. However, inappropriate control way will result in heating energy increasing, so if electrochromic glazing were applied in cold and sever cold region, select ion of appropriate control way was very important.
