    摘要：为研究垂直绿化对重庆地区建筑物夏季室内热环境的影响，对重庆某覆盖有植被的办公楼西向房间进行了CFD模拟分析，通过模拟分析发现，西外墙有垂直绿化可以使房间内部平均温度降低1.5 ℃，垂直绿化房间室内平均风速要比普通房间低0.12 m/s，夏季垂直绿化降低西外墙壁表面温度最高达到16.8 ℃，西外墙有垂直绿化的房间夏季室内平均温度低1.4～2.0 ℃。实测结果与模拟分析的误差小于10%。

    Abstract：In order to study the influence of vertical greening on the indoor thermal environment in summer in Chongqing，this paper carried out a CFD simulation analysis on a westward office room with ertical greening in Chongqing. Through the simulation analysis，it was found that the vertical greening of the westen external wall could reduce the average temperature of the interior of the room by 1.5 ℃，and the indoor average wind speed of the vertical greening room was 0.12 m/s lower than the ordinary room. It showed that the interior temperature of the room with vertical greening was 1.4～2.0 ℃ lower than the average air  and the surface temperature of westward external wall reduced up to 16.8 ℃. The error between the experimental result and simulation analysis is less than 10%.
