Research On Multi-storey Enclosed Building Design Strategy Based On The Wind Environment Of The Courtyard

This research is inspired by the key special projects of the 13-5 National Program.With the rapid development of the social economy,residents' demands for the quality of living environment are increasing.As one of the various physical elements to create a comfortable living environment,the wind environment applications has become more and more popular in architectural design.The enclosed building form is different from the flooded determinant form,and has the same physical characteristics and courtyard features as the traditional courtyard building.It has the dual characteristics of inheriting the context and providing a high volume ratio,but the existing related applications.Cases and research are relatively few and there is a lack of relevant research on their design methods.Considering the introverted courtyard is the main feature of the enclosed building form,this paper chooses a multi-storey building as the research object.From the perspective of wind environment suitability,the comfort of the wind environment surrounding the inner courtyard is taken as the main Judging the basis,through the simulation analysis of the multi-storey building enclosure unit,try to find the correlation between the plane design variables and the comfort of the enclosed courtyard wind environment from the design level.The second chapter of this paper classifies and integrates some common design elements at the plane level through predecessors and some case studies,including two types of building enclosures(openings)and enclosed inner courtyard shapes.And determined the standard containment unit model.In the third chapter,after studying the wind environment theory and evaluation methods,I determined the wind environment evaluation standards applicable to this study.The fourth chapter carries out the wind environment numerical simulation experiment on the standard enclosure unit model determined in the previous section.By changing the different design variables of the multi-layer enclosed building unit one by one,observe the surrounding According to the change law of wind environment in the courtyard,the effect and severity of the changes of various parameters on the wind environment are compared and analyzed,and the conclusions of the design level that can make the wind environment of the courtyard are better.According to the analysis of the simulation results,the importance of the open position of the enclosed building to the trajectory of the airflow in the inner courtyard and the relationship between the design variables and the angle of the incoming airflow and the wind speed are found.Based on this conclusion,the wind environment of the inner courtyard is used as a guide.The design attempt of multi-layered enclosed buildings,through the evaluation of the wind environment of the block,simulates the optimization of the courtyard wind environment for the building block,and designs and deepens the resulting block plan to finalize the design.
