摘要

屋顶绿化作为一种生态的屋顶隔热手段已得到了广泛的认同

以上海气候条件下轻型绿化屋顶为研究对象

采用实测与计算分析相结合的方法

用PMV指标比较室内空调状态下绿化屋顶与非绿化屋顶的室内热舒适性.结果表明

绿化屋顶室内PMV平均值比无绿化屋顶低0.2

波动幅度仅为无绿化屋顶的1/4

并经计算得到绿化屋顶的等效保温屋顶

进一步研究表明

在较高的室内温度情况下

绿化屋顶内表面温度将会低于等效保温屋顶.

Abstract

Roof planting is widely recognized as a ecological thermal insulation for roof. A lightweight green roof in climatic conditions of shanghai was investigated as a case study by applying PMV index to calculate thermal comfort compared with that with traditional roof in air conditioning. It is found that the PMV value of green roof is 0.2 lower than that of traditional roof

while the fluctuating range of green roof was only 1/4 of that of traditional roof. And the equivalent thermal insulating roof of green roof was obtained by computing. Furthermore

it is shown that green roof has lower interior surface temperature than equivalent insulating roof in the condition of higher indoor temperature.
