夏季室内环境空调控制下的热工对比试验证明:屋顶绿化可使屋顶内表面平均温度降低3℃、内表面温度波幅降低80%以上、屋顶传入室内的热流量减少70%以上,绿化的附加当量热阻可达1.0 m2.K/W,有效地改善了室内热环境、减少了空调能耗。
Comparative test on thermal parameters of indoor air-conditioned environment in summer shows that green roof can reduce internal surface temperature 3℃ on average and temperature fluctuation by 80%,heat flow from green roof into indoor can be decreased more than 70% and the additional equivalent thermal resistance due to greening is about 1.0 m2·K/W,which could effectively reduce electric energy consumptions.
