不同类型玻璃在北京地区的节能研究

Energy Efficiency of Various Types of Window Glass in Beijing

分别采用5种不同传热系数和遮阳系数的外窗玻璃,利用建筑能耗模拟软件eQUEST模拟北京地区某办公建筑的能耗,研究分析在北京地区玻璃的传热系数和遮阳系数对办公建筑逐月冷热负荷的影响;在全年能耗方面,6 mm白玻+12 mm空气+6 mm白玻、6 mm Low-E玻璃+12 mm空气+6 mm白玻、4 mm超白玻+13.5 mm气凝胶+4 mm白玻、气凝胶玻璃(遮阳型)相对于12 mm白玻的节能率分别为2%、11%、1%、13%,通过分析比较得出气凝胶玻璃这一新型建筑材料具有较好的节能效果。

The building energy consumption of an office building in Beijing is simulated by using five kinds of window glass with different heat transfer coefficient and shading coefficient with Building Energy Simulation Software eQUEST.It analyzes the influence of heat transfer coefficient and shading coefficient on monthly cooling/heating load of office building.The result shows that,compared to 6mm clear glass,the energy-saving rates of 6mm clear glass＋12mm air＋6mm clear glass,6mm Low-E glass＋12mm air＋6mm clear glass,4mm super clear glass＋13.5mm aerogel＋4mm clear glass,aerogel glazing（shading coefficient） are 2%,11%,1% and 13% respectively in the annual energy consumption.By comparing,this new building materials-aerogel glazing features for good energy saving effect.
