Due to the trend of high-rise and densification of urban buildings, high-rise buildings have a significant impact on the wind environment in their plots, and further affect the comfort of outdoor pedestrians to improve the wind environment around high-rise buildings, which is an urgent problem to be solved. First of all, in this paper, six high-rise buildings in Qianjiang New Town, Hangzhou City, were measured and the location of the building group towards the outdoor wind environment was selected and the points were determined. Then, by constantly changing the orientation of the building blocks, eight typical layouts were obtained. Finally, the CFD fluid dynamics simulation software phoenics was used to analyze the distribution of the wind speed ratio at the height (1.5 m). It is found that the change of the building orientation can achieve the optimization of the surrounding wind environment of the high-rise buildings. This paper, by exploring the relationship between wind environment and building orientation, provides a reference for the design of high-rise building groups in the region.
