Microclimate Evaluation Model Optimization Research Of The External Communication Space Of Subtropical University Campus Based On Urban Diversity Map

Under the background of the increasingly urban high dense development and the contradictory demand for expansion of university campuses in urban central areas,the university campuses in Guangzhou center also gradually show the trend of high density development.With the increase of density,some problems and contradictions of campus environmental quality are increasingly emerging.External communication space is an important part of the campus environment.Most of the communication between teachers and students takes place on it.The quality of space determines the user’s willingness to do activities here.Microclimate comfort is an important factor affecting spatial quality,especially in Lingnan region,where high temperature and humidity are the climatic characteristics.In view of the lack of existing methods for evaluating microclimate environment,this study try to find a method for quickly recognizing and judging microclimate conditions in external communication space.The research contents are divided into six chapters.The research contents are divided into six chapters.The first chapter is to explain the background and current research situation,explain the concepts of related nouns,and elaborate the research methods and framework.The second chapter summarizes the elements of external communication space and the factors affecting the quality of space through literature research,clarifies the importance of the comfort of microclimate environment,and introduces Professor Koen’s method of simulating and analyzing microclimate in hot and humid climate conditions,that is,the map of urban environmental diversity.The third chapter defines the research object and research period.This chapter discusses the application method of urban environmental diversity map in Lingnan area,establishes the threshold of adaptability demarcation of each microclimate factor,establishes the Microclimate Simulation Model of each region through ENVI-met software,establishes five regional environmental diversity maps,and analyses and compares their situation.The forth chapter puts forward the method of observing regional activities through video surveillance,grasps the information of people’s activities in different sites,and analyses the activities in different regions from three levels of " activity quantity","activity behavior" and "activity location",and probes into the relationship between these factors and the external communication space of regional buildings.In the fifth chapter,the residence distribution and the map of urban environmental diversity are overlapped and analyzed.The selectivity of eight different types of microclimate regions is calculated,and the ranking results of their selectivity level are obtained.The evaluation strategy of microclimate environment in external communication space is constructed by using the map of urban environmental diversity.The sixth chapter puts forward two application modes to improve environmental comfort based on the evaluation strategy of external communication space environment comfort based on environmental diversity map.Under the hypothetical conditions,the above strategies are applied to simulate and optimize the design of a square area.
