摘要
实测了三类种植屋面与普通防水屋面的全天温度、热流变化情况,结果证明:种植屋面屋顶内表面温度的峰值、波动幅度以及传入室内的热流峰值均低于普通防水屋面,且植被层密度越大时隔热效果越好;加强人工管理,防止出现大面积土壤外露,将使其隔热效果得到保证。
All-day temperature and heat flux fluctuation of three planted roofs and one ordinary roof were measured. The results show that peak temperature, amplitude and peak heat flux entering into interior space are all lower than those of the ordinary roof; the more vegetation coverage the better the thermal insulation performance; well maintenance and preventing soil from exposure in large area are needed.
