摘要
通过对广州一例种植屋面与通风屋面的实际测试,对比分析种植屋面与通风屋面的夏季隔热效果,得出种植屋面相对通风屋面的隔热效率是1.69。根据实际测试结果,并讨论屋面采用种植与通风后,其空调耗电量、屋顶内表面温度与热流的变化,得出种植屋面比大阶砖通风屋面节约空调能耗约29%。
Both of roofs in Guangzhou was tested,comparing and analyzing the heat insulation efficiency in summer.According to the actual test result,it could proof that the insulating efficiency of the planting roof system is about 1.69 times than the ventilating roof system,analysis the changes in surface temperature and heat flux and energy consumption of air conditioning.Heat efficiency of air-conditioning of planting proof is 29% was stated.Energy saving of air-conditioning in the planting roof system is about 29% than floor tile in the ventilation roof system.
