The presence of building balconies can significantly modify the near-façade wind flow pattern and surface pressures. The present study evaluates the impact of building balcony geometry on mean wind speed on balcony spaces and wind-induced mean surface pressure for generic high-rise buildings. The focus is on balconies that extend along the entire width of the building façade. Large-eddy simulations (LES), validated with wind tunnel experiments, are conducted to investigate the impact of (i) balconies present or not, (ii) balcony depth, (iii) balcony parapet walls, (iv) balcony partition walls, and (v) density of balconies. The results indicate that the balcony geometry can greatly affect the mean wind speed on balcony spaces and the local and façade-averaged mean pressure coefficient (C_p). The presence of balconies can increase the façade-averaged C_p over the windward and leeward façades by 5.2% and 8.9%, respectively. These numbers rise to 23.5% and 23.3% when two partition walls are added at the lateral edges of the façades. Adding five partition walls can reduce the overall area-averaged wind speed on balcony spaces by 68.0% compared to the case without partition walls. These findings can be useful in developing, designing and constructing buildings with façade geometrical details that improve building ventilation, air quality and wind comfort.

建筑阳台的存在会显着改变近立面风的流动方式和表面压力。本研究评估了普通高层建筑中阳台几何形状对阳台空间平均风速和风致平均表面压力的影响。重点是沿建筑立面整个宽度延伸的阳台。通过风洞实验验证了大涡模拟（LES），以研究（i）是否存在阳台，（ii）阳台深度，（iii）阳台护墙，（iv）阳台隔墙和（v）阳台的密度。结果表明，阳台的几何形状会极大地影响阳台空间上的平均风速以及局部和外墙平均压力系数（C _p）。阳台的存在可以使迎风面和背风面的平均立面C _p分别增加5.2％和8.9％。当在立面的侧边缘处添加两个隔墙时，这些数字分别增加到23.5％和23.3％。与没有分隔墙的情况相比，增加五个分隔墙可以使阳台空间的整体平均风速降低68.0％。这些发现对于开发，设计和建造具有立面几何细节的建筑物很有用，可改善建筑物的通风，空气质量和风的舒适度。
