以广州某高校图书馆为例,利用 CFD 模拟方法对建筑立体绿化对室外热环境的影响进行模拟分析,结果显示:在夏季典型计算日,与普通建筑相比,采用立体绿化,建筑前广场、草地、河流上方1.5 m 处温度分别降低了0.5~2.5℃、0.5~2.0℃、0.5~1.5℃,屋面温度降低了8℃左右.采用立体绿化不仅有效改善了室外环境,减缓了热岛效应,而且降低了室外和屋面温度,提高了屋面隔热性能,达到了节能的目的.
以廣州某高校圖書館為例,利用 CFD 模擬方法對建築立體綠化對室外熱環境的影響進行模擬分析,結果顯示:在夏季典型計算日,與普通建築相比,採用立體綠化,建築前廣場、草地、河流上方1.5 m 處溫度分彆降低瞭0.5~2.5℃、0.5~2.0℃、0.5~1.5℃,屋麵溫度降低瞭8℃左右.採用立體綠化不僅有效改善瞭室外環境,減緩瞭熱島效應,而且降低瞭室外和屋麵溫度,提高瞭屋麵隔熱性能,達到瞭節能的目的.

Taking a college library in Guangzhou as an example,the influence of building vertical greening to outdoor thermal environment was studied using CFD method,and the results showed the temperature on 1 .5 m height of building frontal square,the grassland and the river,reduced about 0.5 ~2.5 ℃,0.5 ~2.0 ℃ and 0.5~1 .5 ℃ respectively,and about 8 ℃ on the roofing surface on the summer typical calculation date compared before with after using the vertical greening.Vertical greening not only improves effectively the outdoor environ-ment,but also reduces the heat island effect,and outdoor and roofing temperature,and raises the roof insula-tion performance,and achieves the purpose of energy saving.
