Research And Design Of Multi-story Slab Residential Building Groups Based On Wind Environment Optimization In Yangtze River Delta

Wind environment is an important index to control the environment of residential areas,and it is an important factor that affects the environmental comfort and human health of residential areas.Under the background of green ecology in recent years,Residential wind environments have received more and more attention from designers.This article relies on the sub-project "Research on High-density Building Cluster Design Method for Inheriting Traditional Settlement Organization Ideas in Economically Developed Areas" under the key special topic of the 13 th Five-Year National Key R&D Program "Green Building System Inheriting Chinese Architectural Context" in economically developed areas of China.The design strategy of multi-story residential building groups based on wind environment optimization in the Yangtze River Delta(one of the economically developed areas of China)is discussed.The basic design research idea of this paper is to first analyze the current status of multi-story residential building groups in the Yangtze River Delta,and summarize the spatial organization patterns of existing multi-storey residential areas in the Yangtze River Delta,as a basis for establishing ventilation simulation models later.This article starts from three levels to design ventilation simulation models,using airpark simulation software explore the wind environment characteristics of various layout patterns,in order to summarize the typical design strategy.Chapter 3 discusses the first level,the cluster layout level,with three columns and four rows(approximately 150m*150m)layout scale to explore the outdoor wind environment status under different layout patterns,and uses the average wind speed ratio as the main evaluation index Let's compare results and summarize the layout patterns that are conducive to ventilation.Chapter 4discusses the second level,the building group level,to explore the outdoor wind environment between the courtyard formed by the 4 buildings in the form of 2 rows and 2 columns,and also uses the average wind speed ratio as the main evaluation index.Select and summarize the building groups that is conducive to ventilation.Chapter 5 discusses the third level,the building level,and discusses the impact of different factors such as building plan form,building openings,and building roof forms on the indoor wind environment.Wind pressure difference is used as an index to evaluate the indoor wind environment,in order to select the reasonable building form that is conducive to indoor ventilation.Chapter 6 uses the previous research results to carry out residential planning.This article discusses the influencing factors of residential wind environments from three levels from large to small,and hopes that the design strategy will have certain reference value in the design of high-density residential areas in the future.The whole thesis contains about 42000 words,148 pictures and charts.
