摘　　要：建立两个建筑模型对其相关参数进行监测 ,实测了日辐射强度 ,并从室内外环境两方面分析了外墙表面采用高反照率材料的隔热效果 ,论证了高反照率的墙面材料是有效、主动的隔热方式 ,对减少夏季城市空调能耗具有重大意义。Internal and external microclimate parameters of two building models were measured.The intensity of solar radiation at each part of the models was measured under a certain meteorological condition.The heat insulation effect of high-albedo coating on the indoor air temperature was also discussed.Employing the high-albedo coating of building exterior wall was confirmed to be an active and effective heat insulation method,and is significance of reducing air-conditioning energy consumption in summer.
