摘要
研究了屋顶绿化的节能热工评价方法,通过室内环境为空调控制和自然室温2种状态下的屋顶绿化节能热工对比测试,得到主要结果:在夏季空调期间,绿化屋顶热流减少70%左右,附加当量热阻为1.0 m2.k/w;自然室温环境下绿化屋顶热流方向与对比屋顶相反,绿化屋顶的冷却效率为111%。
Energy consumption and thermal parameters of green roof and bare roof were measured in the air-conditioned and nature indoor environment in summer.It was found that the heat flow of green roof was reduced about 70%,and additional equivalent thermal resistance of green roof was about 1.0 m2·K/W in the air-conditioned,cooling efficiency of green roof was about 111% in the nature condition.
