窗户遮阳技术在节能住宅中的应用研究

外窗是建筑能耗的薄弱环节,同时还直接影响着室内的舒适性。结合上海地区的气候条件,分析了外窗热工性能对建筑能耗的影响,指出提高外窗遮阳性能的重要性。同时对比介绍了几种常用的遮阳技术及性能,并采用建筑能耗模拟分析软件DeST对3种外窗的遮阳效果进行了能耗模拟计算,结果表明,与普通中空窗相比,低遮阳系数的Low-E中空窗具有更好的节能效果。

Eco-Construction Study of Application of Window's Sun Shield Technology in Energy-Saving Building

Outer windows are weak points for building energy consumption and h av e a great influenec on the indoor comfort.Through the analysis of window thermal characteristics based on the Shanghai climate,it shows that window shading play s an important role in improving the energy efficiency of the whole building.Sev eral kinds of window shading are introduced and compared.In addition,the energy performance of three representative windows are analyzed and discussed with the simulation of annual energy consumption by DeST.The results indicate that Low-E double glass windows can have better energy saving effect compared with common double glass windows.
