摘要
以浙南地区的温州大学教师公寓为例,借助计算流体软件STAR CCM+,对小区夏季的风环境进行了模拟与分析。基于《绿色建筑评价标准》对建筑室外风环境的指标要求,探讨了建筑底层架空与不架空两种不同的设计形式对小区风环境的影响,结果表明:建筑物采取首层架空设计后,明显改善了该区域内的人行高度的风环境,促使小区内的流场趋向平稳,无明显紊流区出现,有利于空气流通,有效减少了污染空气的滞留。由于浙南地区的建筑主要受夏季风的影响,所以本次实验选择夏季风(东偏南45°)进行模拟,对比架空与不架空这两种设计形式对小区内风环境的影响,并运用模拟分析的方式探讨如何调整建筑造型及整体布局,并在最终的设计阶段进行合理运用,在一定程度上改善风环境,使之符合我国《绿色建筑评价标准》中的相关要求。
Teachers’ Apartment Wenzhou University in southern Zhejiang is chosen to simulate and analyze on the summer wind environment with the computational fluid dynamics software STAR CCM＋. Based on requirements in“Evaluation Standard for Green Building” for outdoor wind environment, the pa-per presents the influence of the two different forms of design, namely overhead and non-overhead con-struction, on the wind environment of residential area. The results show that wind environment at the pedestrian level is significantly improved;the flow field within the district tends to be smooth and no signif-icant turbulence zone. The design is also beneficial to improve air circulation and reduce air pollution re-tention. Due to construction in southern Zhejiang mainly be affected by the summer monsoon, the summer monsoon （East southerly 45° degrees） is selected to simulate and analyze, comparing effects of two forms of design to the wind environment within the district. The layout and modeling of the building will be adjusted through the simulation and analysis, eventually applying for the construction design stage. To some extent, it could improve the air environment and accord with our evaluation criteria of green building requirements.
