Research on Wind Environment around Residential Buildings with Different Planning and Design Factors

Abstract:

In this work, a field survey is performed in 309 residential building clusters in South China to obtain the basic characters of urban planning and design of residential buildings in this area. Based on it, the basic model of residential building clusters in this area is established, and CFD method is used to simulate the outdoor wind environment around residential buildings with different planning and design factors. The influence of building coverage ratio on the pedestrian spatial mean velocity ratio under 16 wind directions is found to be more remarkable than those of the floor area ratio and building layout. 10% increase of the building coverage ratio results in 0.1 linear decrease of the mean velocity ratio under 16 wind directions at the pedestrian level.
