摘　　要：气凝胶半透明复合保温板是导热系数超低的气凝胶材料夹层与边界透明材料保护层组成的复合构造,可用于建筑幕墙,实现保温节能。其保温效能高于同样厚度的建筑用节能中空玻璃。但气凝胶半透明复合保温板只适用于冬季以采暖能耗为主的建筑,对夏季以制冷能耗为主的建筑无明显节能效果。目前建筑中应用气凝胶半透明复合保温围护结构不一定都具有经济合理性,工程中应采用能耗分析与投资回收期经济性分析相结合的方法,找出价格适宜的气凝胶半透明复合板,才能保证其用于低能耗建筑幕墙的经济合理性。Aerogel translucent composite panel is a structure comprising of an aerogel in-between layer with ultra low thermal conductivity,and boundary transparent protective layers.They can be utilized in curtain walls of a building for improving energy efficiency via thermal insulation.The insulation capacity of an aerogel translucent composite envelope is always better than that of a high performance double pane glazing with the identical thickness.Nonetheless,in terms of energy efficiency aerogel translucent composite envelopes are only effective for buildings requiring mainly heating energy in winter,not for buildings consuming more cooling energy in summer.Currently it is not always economically feasible for applying aerogel translucent composite envelopes with the purpose of improving the building energy efficiency.In engineering practice,it is advisable to implement energy analysis and payback period calculation together to determine the optimized cost of aerogel building envelopes in order to ensure the economical feasibility of the curtain walls of an energy efficient building.
