Study On The Optimization Of The Spatial Form Of The Teaching Center Area Of University Campuses Based On The Improvement Of Microclimate

As an important part of the city,improving the microclimate of the university campus will help improve the thermal comfort of the human body,improve the utilization rate of outdoor space,and increase the vitality of the campus.The campus is large in scale,and the layout of building groups is closely related to the campus microclimate.The construction of microclimate is inseparable from the big climate background.Under different climate backgrounds,the layout of building groups and microclimate have different influence mechanisms.This topic takes the climate of severe cold areas as the background,focuses on the influencing factors and change rules of the outdoor thermal environment of the teaching center area under different structural layout,and summarizes the microclimate regulation methods suitable for the teaching center area in severe cold areas.Firstly,this study analyzes climatic characteristics of server cold areas and limits the study in a specific region.Altogether,the study makes a systematic investigation and analysis of 43 campuses in the set region.We categorize spatial forms into different types based on their different structures and textures.Through statistic analysis,we obtain the basic construction forms of geometric models and morphological parameter threshold.In addition,we make actual measurement of the microclimate on typical campuses and analyze the distribution characteristics of campus microclimate.Secondly,we study the relevance between morphological index of space texture and temperature based on measured date and the properties of enclosed space and open space.We also deduce the multiple regression equation in regard to relevant morphological indexes of air temperature.In addition,this study analyzes the correlation between the index of texture morphology and wind speed.This study also combines actual measurement with questionnaire analysis to find out people’s different comfort levels under different motion states on campus.By above combined analysis,this study works out the mathematical model of thermal sensation and climatic factors,which provides basis for optimizing model parameter scale and optimizing performance.Thirdly,by adopting SPEA2,we seek to achieve optimal effect of sunlight,radiation and wind speed.Based on the classification of teaching areas and relevant morphology threshold value,this study sets constraints on Grasshopper(a parameterization construction platform)and constructs abstract model.This study also makes performance simulation,including solar radiation duration,solar radiation quantity and wind speed distribution.According to our optimization targets,this study carries out Pareto Optimality iterative analysis.With a large number of case operations,this study finds out the optimal layout solution set.In line with iterative optimization procedure and relevant data as well as the layout law extracting from layout classification,this study put forwards corresponding optimization design in respect to morphology scale,building height and degree of aggregation and architecture orientation.
