With the rapid development of distributed energy resource and urbanization, it gradually becomes a great concern on utilizing wind energy resources in city buildings. In this study, a model of the main building of North China Electric Power University was built by Gambit and the numerical calculation was performed in the flow field to discuss the wind power generation potential with the computational fluid dynamics method. Then, characteristics of wind energy distribution were analyzed, and some sections with large wind velocity, such as passageway, rooftops and corners, were chosen to conduct further analysis with denser meshes. Finally, considering different types of wind power use patterns and different constructions, the optimization design of wind turbines was proposed to solve the problem of wind power utilization in cities and the concentrated concept was brought in wind power utilization of constructions for the first time. Study results of this paper can provide references for the wind power utilization in buildings and distributed generation in the urban areas.
