Influence Of Courtyard Space On Wind Environment In Hot Summer And Cold Winter Zone

At first,the courtyard appeared in the traditional Chinese official architecture,garden architecture,and residential community.The courtyard created a sense of domain and belonging,and introduced the outdoor natural environment to the interior of the building,which was in line with the psychological needs of the people,so the courtyard was deeply loved and welcomed by the people.However,the courtyard also has the attribute of gray space,not only the junction of indoor artificial environment and outdoor natural landscape environment,but also the transition space of outdoor adverse environment into the interior.Therefore,how to effectively use courtyard space to improve the surrounding environment of buildings and avoid adverse factors has become the top priority of courtyard design.Now many of the single buildings have also used the courtyard layout,different from the previous closed layout,the present courtyard is mostly half enclosed space,virtual and real combination has become a common form of compound,such as the atrium,the corridor,semi enclosed entity space,overhead walkways and other combination into the courtyard space.Although we all know that the courtyard layout can improve the environment of the courtyard space,but what is the influence of the courtyard layout on the wind environment in the courtyard space? How does it affect the wind environment of courtyard space? Which form and relative scale of the courtyard space wind environment is more suitable for human activities?This paper first introduces the basic theory of air fluid mechanics,analyzes and summarizes the characteristics of the wind flow around the building,and then takes the 13# teaching building of the Eastern Campus of Jingzhou city as an example.Through the evolution and simplification of the building model,the wind environment of a variety of courtyard spaces is analyzed by computer numerical simulation,and the model is evaluated and the model is evaluated.The wind environment of the courtyard space is better.Finally,a simple courtyard combination mode is used to verify the relevant conclusions.The purpose of this study is to provide qualitative or quantitative theoretical basis for the design of building wind environment.
