屋顶绿化夏季对室内的降温效果试验对比研究

Study on Cooling Effect for Room of Green Roof in Summer

随着城市化进程的不断加快,城市绿色植被面积不断减少,造成城市空气质量恶化,热岛效应逐渐加重,而屋顶绿化则是解决上述问题的方法之一。本文利用三个木屋模型建筑,分析埘比了两种不同植物的屋顶绿化在夏季对室内的降温效果。研究表面,两种绿化对降低屋顶内表面温度和室内温度效果明显,不同的绿化方式其降温效果也有一定差异,对屋面植物定期浇水维护可以使降温效果进一步加强。

Urbanization is developing very fast but the urban green area has decreased and it also caused the deterioration of urban air quality and the increasing of heat island effect. The green roof is one of the methods to solve above problems. This paper did experiment on green roof with two different plants in order to compare the effect of the reduction of the indoor temperature in summer by three wooden buildings. It can be seen that two green roof buildings have obvious effect to reduce the indoor temperature and different plant has different cooling effect. It could get better cooling effect if plants had regular watering.
