屋顶绿化对室内人体热舒适的影响研究

进行了夏季屋顶绿化对室内热环境影响的实验研究,结果表明:室内空气和维护结构内表面温度均有不同程度的降低,这是有利的;然而房间的相对湿度升高了,这是不利的;综合效果是人感到热改善为基本能接受;当热环境要求高时,仅靠屋顶绿化一个手段还达不到令人满意的效果,还必须采用其它手段比如夜间开窗通风,利用电风扇使室内产生一定的风速以及空调等的综合作用。

Research on the Impact of Green Roof on Indoor Human Thermal Comfort

An experiment is conducted on the impact of green roof on Indoor Human Thermal Comfort.The re-sult shows that the temperatures of the building walls and indoor air fall for certain degrees,and that is good.But unfortunately,the relative humidity of the indoor air rises.Totally speaking,the whole effect is changed from feeling warm to basically acceptable.When the requirement of the indoor environment is high,it is impos-sible to be satisfied by exploiting green roof solely,other methods,such as using night ventilation,electric fans or air-conditioners,should be taken at the same time.
