Analysis on Layouts of Pedestal and Adjacent Podiums in Hangzhou in Wind Environment

To explore how the pedestal and adjacent layout of podiums around highrise office buildings affect the wind environment at the pedestrian height (1.5 m) of outdoor, a single highrise building in the area is selected as the object to analyze its position, height, windward side width and thickness of base type. The enumeration method is employed to obtain a variety of typical layouts, and CFD (computational fluid dynamics) simulation software Phoenics to simulate the outdoor wind environment. By comparison, the optimal layouts of pedestal and adjacent podiums is found. The results show that, when designing podiums in the area dense with high-rise buildings in Hangzhou, the adjacent layout of podiums is better than the pedestal. When the podium height ranges between 15.0 m and 20.0 m, its windward side width is about 70.0 m, and its windward depth is between 50.0 m and 60.0 m, the wind environment is most desirable
