摘　　要：轻型屋顶绿化节电效果试验表明:采用屋顶绿化比未有屋顶绿化的房间用电量减少0.1066 kW.h.d-1.m-2或0.0333 kW.h.d-1.m-3;白天减少20.9%,夜间减少15.3%,全天减少18.4%。室外温度越高,屋顶绿化的节电效果越大,两者呈显著直线关系。An experiment of light roof greening was carried out in order to study the effect on saving electric power consumption during summer.The results showed that compared with bare roof,greening roof could effectively reduce indoor electric power consumption by 0.1066 kW·h·d^-1·m^-2 or 0.0333 kW·h·d^-1·m^-3,20.9% in the daytime,15.3% at night,and 18.4% all day.The higher the outdoor air temperature,the greater the electric power saved by roof greening.
