Coupling Study Of Spatial Morphology And Outdoor Wind Environment Of University Campus In Guang Zhou Based On Regression Analysis

The standards of new green building evaluation puts forward the concept of environmental livability,the research of green building is not limited to the environment and energy,and transfer to green ecological urban areas,low-carbon cities and green campuses gradually.To build a green campus is a significant measure to promote sustainable development of society,however,the majority of campuses lack climate comfort design which is lack of green design concepts in the site design and layout stage.This thesis intends to explore a set of research methods on the relationship between space and microclimate by verifying the coupling relationship between the campus space form and wind environment in Guangzhou,combining ‘environment livability' with campus space and function.In the process of improving the construction of campus,focusing on the ‘wind environment comfort' of the outdoor environment has become one of the most valuable research directions in green design.By exploring the coupling relationship between the morphological parameters of the campus city texture and the wind environment,establishing a set of campus city texture design and wind environment adaptability of the campus in Guangzhou which can be regarded as a benchmark for dynamic debugging.putting forward the wind environment-oriented of urban campus and urban design strategy system in Guangzhou is proposed as the principle for determining the intensity of land development,and the design guidelines for campuses for planners and architects to deal with the optimization of wind environment.This paper aims to classify and define the urban spatial form of Guangzhou campus by literature research,GIS data collection,3D model drawing,PHOENICS simulation and SPSS data post-processin.Taking comfort zone and calm wind area as evaluation standard,evaluates the condition of different types of outdoor spaces campus and concludes the problems which to be solved.Applying the linear regression relationship is to draw up a wind environment-oriented urban design strategy and provide suggestion of green design for designers.This thesis is divided into five Chapters.Chapter one is theoretical research,which mainly discusses the background,object,content,purpose and significance,and summarize the the relationship among microclimate with wind environment,urban spatial morphology and urban texture morphological parameters.And theoretical research stats of correlation and linear regression.This four relationships runs through the full paper's conception between space and green,which provides a scientific basis for electing topics.In chapter two,study of urban spatial form,which mainly discusses the significance of urban design to the improvement of microclimate,and raises the key points of constructing spatial form.After determining study object,the development trend of universities in Guangzhou is briefly explained and 10 crucial urban texture morpholo gical parameters are proposed based on the character of urban spatial.Using GIS to carry out data collection and function calculation of related parameters,and using bivariate Pearson correlation coefficient of SPSS,the spatial shape of campus corresponding to different urban texture morphological parameters was clarified.Chapter three discussed the basic characters of wind environment in Guangzhou,then put forward basic requirement of wind environment comfort and health,next,combined with the fundamental principles of CFD,determined PHOENICS as the wind environment simulation software in this paper.Using the collected theory and experimental experience,the wind environment simulation experiment of 42 university campus case samples was completed,and the relevant data of average wind speed,comfort zone area ratio and quiet wind zone area ratio were obtained to determine the optimal wind environment conditions.Chapter four is to classify the 42 case samples according to different types of campus spatial morphology,and get recommended recommendations through the wind environment optimization conditions.By using SPSS to perform linear regression analysis method,and post-process data of different types of case samples to obtain corresp onding univariate or multiple linear regression formulas,interpreting the corresponding optimization design methods of different types of spatial forms.Recommended suggestions and optimized design methods are the prerequisites for formulating urban design strategies following content.Chapter 5 is based on Chapter 4 and benchmarked three national-level green design-related standards.From the preliminary planning,site design and building layout,building up 19 urban design strategies and methods are based on wind environment optimization.In the end,the results are summarized and the deficiencies and future prospects are proposed.
