中文摘要：
采用所研制的室外防护热箱实验装置，对佛甲草和轻型种植土2种轻型屋面隔热模块的节能性及隔热特性进行了对比研究。测试结果表明：在同一气候条件下，佛甲草模块热箱的箱内空气温度比室外空气温度平均降低5.4℃，比轻型种植土模块箱内空气温度低约0．8℃；佛甲草模块热箱内的平均累计耗电量为0．27kW·h／m2，与轻型种植土模块相比，平均节电量为0．05kW·h／m2，节电率为15．6％。
英文摘要：
In this paper the properties of energy saving and thermal insulation for the two lightweight roofing insulation modules with sedum lineare and light planting soil are studied by using the outdoor guarded hot box device. The experimental results show that the indoor air temperature of box with covering the sedum lineare module is reduced about 5.4 ℃ averagely than the outdoor air temperature,however it is lower 0.8 ℃ than the indoor temperature of box with covering the light planting soil module in the same climate conditions. The average cumulative power consumption of box with the sedum lineare module is about 0.27 kW·h/m2,and the electricity that could be saved is about 0.05 kW·h/m2 comparing with the light planting soil module,the energy saving rate is about 15.6%1
