Abstract: With the rapid growth of China’s urbanization, the wind environment of residential
districts is getting people’s attention more and more. The winter windproof and summer natural
ventilation are particularly important for Wuhan city which is hot in summer and cold in winter. This
paper establishes the model of planning residential district by using software of Airpak3.0 and
researches the relationship between the layout of building and wind by using   Turbulence
model to solve the speed and pressure of residential district. The results demonstrate that computer
numerical method can simulate the wind field accurately and wind environment is influenced
obviously by the layout of residential district and inflow direction. Using numerical simulation
method and reasonable building planning with the city wind rose can provide guidance and
optimization of building planning construction for residential district in Wuhan area.

Key words: residential district, wind environment, computer simulation, building layout
