西安地区办公建筑南窗水平遮阳研究

Study on South Windows Overhang of Office Buildings in Xi'an Area

通过窗户的太阳辐射对建筑夏季空调能耗和冬季采暖能耗有着重要的影响,对于南向窗户来说水平遮阳方式比较有效。以西安地区办公建筑南向窗户为研究对象,借助Energyplus等软件,分析了夏季通过南窗太阳能辐射得热问题,综合考虑不同水平遮阳板宽度对建筑采暖和空调负荷的影响,得出了遮阳板最佳设计尺寸。

Solar radiation through the windows has a significant impact on the energy consumption of heating and cooling. The overhang is more efficent for south windows. Taking south windows of offwe buildings in Xi＇an area as an object, the software of Energyplns was used in analyzing the solar radiation heat gained by south oriented windows. In addition, the optimal dimensions of shading device have been presented by considering the influence of different overhang width on cooling load and heating load.
