武汉地区住宅小区的风环境模拟及评价——以武汉大学茶港小区为例

Wind Environment Simulation and Evaluation of the Residential District in Wuhan: A Case Study of Chagang District in Wuhan University

建筑室外风环境模拟是绿色建筑认证模拟中的重要一项内容。该文以武汉地区的自然气候条件为基础,运用Airpak软件的RNG模型对武汉大学茶港小区冬夏两季风环境进行了数值模拟和评价。通过模拟住宅小区建筑环境的室外舒适度和建筑单体压力分布的情况,研究得出该小区基本符合国家绿色建筑评价标准中对住宅室外风环境的要求:冬季室外行走舒适及夏季自然通风。同时,该模拟可从构建良好的风环境角度来指导当地住宅小区规划设计和方案决策。

Architectural outdoor wind environment simulation is an important part of green building certification. This paper is based on the natural climatic conditions of the Wuhan region, using RNG model of software of Airpak to simulate and evaluate the wind environment of Chagang district in Wuhan University both in summer and winter. Through the simulation of outdoor comfort of the building environment and building monomer pressure distribution in the residential district, we find that the residential district meets standard of the national green building evaluation for outdoor walking comfort in winter and natural ventilation in summer. At the same time, this simulation can guide the local residential district planning and design program decision-making from the view of forming excellent wind environment.
