            摘要:

            针对重庆地区某6层居住建筑,利用DesignBuilder软件进行能耗模拟,从建筑自遮挡、互遮挡、植被遮挡3个方面研究了遮挡对山地居住建筑能耗的影响,并将3个方面结合起来进行了综合建模和分析。模拟结果显示:综合3种遮挡措施,太阳得热量减少约50%;热湿环境较为恶劣的西向,建筑能耗降低18%,其他朝向降低不到10%。

            Abstract:

            Taking a six-storey residential building in Chongqing as an example, investigates the shading effects on the energy consumption from three aspects of building itself, neighboring buildings and nearby plant with DesignBuilder software, and conducts integrated modeling and analysis. The results show that with the integrated three kinds of shielding measures, solar heat gain is decreased by about 50%. The energy consumption is decreased by 18% for the west with poor thermal and humid environment, and by less than 10% for other orientations.
