Study On The Optimization Of External Shading Of Teaching Building In College Station Vocational Education Of Zhuzhou

With the improvement of living standard,people pay more and more attention to the quality of living environment.In summer,the solar radiant heat enters the room through the external window,which not only increases the indoor stored heat but also increases the energy consumption of the cooling equipment.The investigation shows that setting a reasonable external shading system in the external windows of public buildings can block most of the sunlight,which is not only conducive to building energy conservation,but also conducive to building a good indoor light and thermal environment.In this thesis,based on the theory of industry research construction outside shading,outside the building shading,performance characteristics and relevant research methods in the form of system has carried on the deep analysis of the zhuzhou vocational college teaching building towards,outside shading model and effect of field survey analysis,and establish the model of typical classroom,from the Angle of passive control,simulation and daylighting effect and building energy consumption analysis,Optimize the fixed exterior shading system of buildings,improve the indoor light and thermal environment quality of teaching buildings in Zhuzhou Vocational Education College Town in hot summer and cold winter areas,and focus on the design key points and optimization strategies of fixed exterior shading of teaching buildings in this area,mainly including model establishment,simulation calculation and analysis and summary of three stages,as follows:1)Model establishment: by referring to the investigation results of zhuzhou vocational education college town,three basic models are established,which are classroom model 1 with inner corridor layout(one side of the far corridor is glass curtain wall),classroom model 2 with inner corridor layout(the outer window is ordinary window)and classroom model with outer corridor layout(the outer window is ordinary window).2)Simulation calculation: according to the local climate characteristics and the service time of the teaching building,six shading forms of horizontal plate,vertical plate,baffle,comprehensive,horizontal louver and vertical louver were set for the simulation calculation of energy consumption and lighting.3)Analysis and summary: according to the research results,the optimization setting principle of exterior shading is put forward,and the optimization suggestions of exterior shading form and component size of different building window opening modes are put forward.The results of this study provide a new method and technical support for improving the indoor light and thermal environment of teaching buildings in university towns by setting up external shading,so as to further reduce the carbon emission of teaching buildings.
