建筑群布局与自然通风关系的研究

自然通风是建筑实现节能、健康、生态等目标的重要手段。建筑楼群的布局方式既关系到建筑室外人员活动区域的舒适性,也影响建筑单体前后的压力分布。本文以广州地区的自然气候条件为基础,对常见的楼群布局方式的总体通风情况进行了计算机模拟与分析,结合风速、压力差和WBGT等指标,对不同楼群布局方式的优劣进行了比较分析。

Study on Relationship between Building Group Distribution and Natural Ventilation

Natural ventilation is an important approach to realize the energy conversation,healthy housing and ecological building.The geographical distribution pattern of building group not only affects the people's outdoor thermal comfort,but also the air pressure before and behind the building.In this paper,based on the climate characteristics of Guangzhou,the nature ventilation for common building group distribution pattern was simulated and analyzed according to the indexes of velocity,pressure difference and WBGT value.With the simulation results,the advantages and disadvantages for different building group distribution pattern were discussed.
