摘　　要：为了研究遮阳网和绿化层的隔热降温效果,对某小区住宅楼有、无绿化屋顶进行了连续测试。分析测试结果发现:仅绿化层作用下,平均温度和最高温度分别降低23.8%、36.9%;仅遮阳网作用下,平均温度和最高温度分别降低33.3%、38.7%;绿化层和遮阳网共同作用下,平均温度和最高温度分别降低35.6%、45.5%。对屋顶进行绿化和加设遮阳网都能有效地改善阳光直射屋顶而导致的屋顶过热现象,两者共同作用下的隔热效果更好,可进一步降低室内空调能耗,达到建筑节能的效果。In order to study the effect of heat insulation and cooling of shading net and green layer,continuous tests are carried out for a residential building with or without green roof. Analyzing results of test,it showed that only with the effect of greening layer,average temperature and maximum temperature were decreased by 23. 8%and 36. 9%; Only with the effect of shading net,the average temperature and maximum temperature were decreased by 33. 3%and 38. 7%; With the effect of greening layer and shading net,the average temperature and maximum temperature were decreased by 35. 6%and 45. 5%. Both roof greening and shading net can effectively improve the overheating of roof caused by direct sunlight,and the heat insulation effect is better. It can reduce indoor air conditioning energy consumption to achieve the effect of building energy efficiency.
