A Study On The Relationship Between Outdoor Space Form,Behavior And Outdoor Thermal Comfort In University Campus

With the continuous definition of the connotative development goal in China,great changes have taken place in China’s educational philosophy and education methods.As the bearing place of new education mode and the place of teachers and students’ daily life,the design quality and comfort degree of university campus directly affect people’s use condition.However,there are still many problems in the current campus outdoor space,such as the gap between the construction goal of some campus outdoor space and the students’ real behavior and activities,and the insufficient consideration of the outdoor space comfort,especially the thermal comfort.This paper focuses on the outdoor space of university campus in Nanjing,summarizes the typical models of outdoor space at different levels,and studies the correlation between behavior activities and outdoor thermal comfort,and between space form and outdoor thermal comfort by field research and software simulation.In order to provide a positive reference for the campus space precision,humanized design and quality improvement.First of all,through the existing literature review and research,summarizes the development of universities and their outdoor space in China.According to the service radius and location of outdoor space,it can be divided into three levels: campus level,group level and building level.Through the research of environmental behavior related knowledge,this paper discusses the mechanism of environment and behavior,and extracts the relationship between space form,behavior activity and outdoor thermal comfort: space form has a direct impact on users’ behavior and outdoor thermal comfort;the change of physical elements of outdoor thermal comfort can also affect people’s use condition;behavior Activity and outdoor thermal comfort as affected people,their activity status and comfort degree to a certain extent reflect the quality of space form,and play an important feedback role.Based on the relationship between the three,further study its specific quantitative indicators and lay the foundation for the quantitative analysis in the following paper.Secondly,based on the previous research,the outdoor space of university campus in Nanjing is preliminarily investigated and analyzed.Collect the basic information of space form index,land use scale and building scale of each outdoor space.Taking Sipailou campus of Southeast University as an example,the thermal comfort and behavior activities were deeply studied.The physical factors influencing outdoor thermal comfort,such as temperature,wind speed,relative humidity and black ball temperature,were collected.At the same time,we observed and recorded the behavior status of each level of space.Finally,on the basis of the previous survey,the relationship between space form,behavior and outdoor thermal comfort is studied.Focus on the relationship between behavior activities and outdoor thermal comfort,as well as the relationship between space form and outdoor thermal comfort: with the help of SPSS software,analyze the relationship between outdoor thermal comfort(PET),air temperature,wind speed,relative humidity and behavior activities.With the aid of envi-met software,the quantitative indexes such as orientation,scale,impervious area ratio,material and its albedo,and non quantitative indexes such as building layout and plant species on pet value were quantitatively analyzed.Finally,based on the correlation between behavior activities in each space and outdoor thermal comfort,according to the correlation between space form and outdoor thermal comfort,optimization suggestions are put forward for different levels of university campus outdoor space.
