摘要
本文将位于夏热冬暖区的厦门市近郊藤架式屋顶绿化作为对象研究,实测屋顶绿化房间和紧邻无绿化措施房间的数据,采集两个房间室内和室外空气温度、楼板温度、PMV等多项影响人体热舒适的参数。通过实际测试与CFD模拟综合对比,分析夏季藤架式屋顶绿化对建筑顶层房间热环境的影响。数据显示,藤架式屋顶绿化使屋顶表面温度最大降低12.35℃,室内空气温度日均降低0.68℃,分析得出藤架式屋顶绿化在一定程度上改善了顶层建筑热环境,是一种有效改善居民生活热环境的途径。
In this paper,the roof greening of pergola in the suburb of Xiamen,which is located in the hot summer and warm winter zone,is taken as a research object.The data of the green roof room and the adjacent room without greening measures are measured.The indoor and outdoor air temperature,floor temperature,PMV and other parameters that affect human thermal comfort of the two rooms are collected.Through comparative analysis of actual measurement and CFD simulation,the influence of summer pergola roof greening on building thermal environment is studied.The results show that the pergola roof greening reduces the outer surface temperature of the roof by 12.35℃,and the indoor air temperature decreases by 0.68℃per day.Therefore,it can be concluded that the pergola roof greening improves the thermal environment of the top floor building to a certain extent,which is an effective way to improve the living environment of the residents.
