基于数值模拟的单体建筑室内外风环境优化研究——以招商北固湾绿色社区中心设计竞赛方案为例

Optimization of Interior and Exterior Wind Environment of the Single Building Based on Numeral Simulation: Taking Design Contest of Zhaoshang Beiguwan Green Community Centre as an Example

以2012年招商地产绿色建筑设计竞赛的获奖设计方案(创意奖)为例,摘取其中风环境分析部分,说明利用FLUENT软件在建筑设计初期对建筑方案进行推敲的过程。通过对建筑不同体量组合下的室外风环境进行模拟和不同开窗样式下的室内风环境模拟,分析室内外风场存在的问题,进而提出相应的修改策略,最终得到利于建筑自然通风的设计。结果表明,将建筑信息输入风环境分析软件,可以直观地看到建筑室内外风场分布,便于建筑师在设计前期及时发现问题,有针对性地修改设计。

Taking design contest of Zhaoshang Beiguwan green community centre as an example, the interior and exterior wind environment are expounded by the numeral simulation. Through the numeral simulation of the exterior and interior wind environment under different circumstances, the unfavourable wind problems are analyzed with corresponding modification. Result shows that we can easily identify wind environment by importing building information into CFD analysis tools（FLUENT）, and modify our design purposely.
