使用计算机模拟技术对大型住宅小区室外风环境的特点进行了模拟分析;着重对影响人居环境的住区室外风速分布以及建筑外立面的风压分布等特性进行了模拟计算;研究了此类建筑室外风环境优化设计的关键因素;研究结果表明,首层架空以及周围开敞式设计可以有效引导外部气流深入小区内部,从而改善小区的室外通风和热环境。 The characteristics of the outdoor wind environment in large-scale residential quarters are simulated by computer simulation technology. The characteristics of outdoor wind speed distribution and the wind pressure distribution of the building facade which affect the living environment are emphatically studied. The results show that the first floor overhead and surrounding open design can effectively guide the external airflow into the interior of the residential area, thus improving the outdoor ventilation and thermal environment in the residential area.
