摘要
建立了水平外遮阳阴影面积计算模型，以广州地区某办公建筑为例，分析了设置与不设置水平外遮阳的建筑外窗在5～9月空调时段的冷负荷．结果显示：在分析的空调时段，设置水平外遮阳的建筑外窗冷负荷比不设置时分别降低：南向12．7％，西向8．4％，东向8．0％，北向5．9％．
The calculation model of shadow areas of the horizontal sunshades is established, and the cooling load of outer windows of an office building in Guangzhou in the period of air conditioning from May to September is analyzed under setting and not setting the horizontal sunshades. The results show the cooling load of outer windows under the horizontal sunshades decreases separately in the south by 12.7% , the west by 8.4% , the east by 8.0% and the north by 5.9% to no shade.
