The wind environment around residential building groups is increasingly concerned, while the dwelling groups as the elementary unit of planning design, its quality of surrounding wind environment will directly affect people’ s life. This study based on the climatic conditions of severe cold regions, selects four dwellings groups with different openings scale and position as the research objects, and then simulates and analyzes the wind speed distribution characteristics of each pattern. Meanwhile, it extracts the wind speed values of one hundred points of each pattern and applies the coefficient of uniformity method to the ecological evaluation. It has been found that grouping pattern of buildings has a dramatic effect on the resulting airflow behavior. Configurations that contain a T⁃shaped central space with small opened side can effectively prevent and contain airflow in the site offer. The interactive influence between layout of dwelling groups and wind environment are explored, so as to provide basis for the planning design of dwelling groups.
