Research On Energy-saving Potential Assessment Method Of Primary School Climate Space In Humid And Hot Areas

With the rapid process of urbanization,dense architectural forms have changed the spatial structure of the urban surface.The extreme artificial environment has caused a series of climate and environmental problems,and the human ecosystem has suffered unprecedented pressure.However,with the rapid development of cities in China’s coastal hot and humid areas,the conflict between urban form and climate conditions is becoming more and more intense,resulting in a significant increase in building energy consumption.On the other hand,the rapid growth of population and the shortage of degrees directly lead to the contradiction between the incremental construction of campus and the lack of constructable land.High density urban areas and campus space will also affect the thermal environment of campus.Compared with residential buildings,the volume,layout and spatial organization of campus have the potential to respond to the regional microclimate to a certain extent.Therefore,this paper will be based on the climate space design of primary school buildings in the typical humid and hot area city of Shenzhen,take the thermal comfort of classroom unit human body as the starting point,study the energy-saving mechanism of climate space on campus buildings through qualitative and quantitative methods such as case study,investigation and measurement,simulation experiment and so on,construct the energy-saving potential evaluation method of campus building climate space in humid and hot area,and summarize its characteristics and laws,It provides reference and suggestions for the design and use mode of primary school buildings in this area.Based on the research purposes,research of this paper is divided into the following aspects:Firstly,it introduces and analyzes the climate environment in Shenzhen,and summarizes the climate design strategies in hot and humid areas combined with traditional architecture and contemporary design practice.At the same time,based on the existing climate space design theory,this paper analyzes the climate space sub items and combination forms of primary school buildings in hot and humid areas.(Chapter II)Secondly,starting from the action mode of primary school climate space in humid and hot areas,this paper attempts to construct a method for evaluating the energy-saving potential of primary school building climate space in this area.Select the typical day of the transition season to conduct the actual measurement and analysis of the research object,summarize the law of the external space wind and heat environment of its physical environment,and verify the performance simulation software with the measured data to verify the scientificity and reliability of the main hydrodynamics simulation software.(Chapters III and IV)Then,taking Xinzhou primary school as a research case,the climate free space scheme and the traditional energy consumption calculation condition are established as the comparison item to verify the energy-saving effect and law of the original climate space combination in the transition season.At the same time,it shows that the energy-saving potential evaluation method in this paper can better reflect the role of climate space.(Chapter V)Finally,based on the problem that the energy benefit in the autumn transition season is not obvious,the scheme is optimized for the climate spatial combination,and the multi condition comparative study is carried out from the position and size of the spatial item,so as to determine the specific climate spatial physical attributes of the optimization scheme.(Chapter VI)Using the multi software collaborative design method of building performance simulation platform,this paper focuses on the characteristics and action mode of high-density urban campus climate space in hot and humid areas,and constructs an energy-saving potential evaluation method of climate space in hot and humid areas with human thermal comfort as the core.Combined with the action mechanism of climate space,this method can quantify the impact of climate space combination on the external wind and heat environment and the energysaving effect on the building energy consumption space in the architectural design stage,give suggestions on the design process of high-density primary schools in humid and hot areas,and give a set of design ideas and theoretical methods suitable for feedback optimization and regulation in the design process,so as to provide a scientific basis for the design process,It is of certain significance to promote the development of green buildings and energy conservation and emission reduction.
