The Influence Of Facade Visor Combination On The Light Environment Of Middle School Teaching Buildings In Guangzhou

Natural light is a necessary condition for indoor and outdoor communication,and the design of building facade has a crucial relationship with the quality of light environment.Good indoor natural light environment is beneficial to students’ physical and mental health.The shading design plays an important role in regulating the light environment inside the classroom,which can not save energy,but also avoid glare and improve indoor comfort.In nearly a decade,new technology,new software and software support is more complex and dynamic parameters of the study appear in architectural lighting,from the perspective of indoor lighting area optimization teaching building light environment of the study is more,the study of natural light environment focuses on a single full of window shade way research,the research of the full window shade is less,also lack of comparative study of different forms of shade,not conducive to the scrutiny and contrast in the process of architectural design.Taking the teaching building as the research object,this paper aims to explore the relationship between the different sunshade combination forms and the natural lighting environment inside the classroom under the climate conditions of Guangzhou,as well as the organic combination of architectural technology and art.After discussing the basic knowledge and evaluation index of the natural light environment in our country,the design requirements and norms of the middle school teaching buildings,the paper summarizes the characteristics and problems of the natural light environment of the middle school teaching buildings in Guangzhou under the climate conditions by analyzing the field research and the results of the lighting test of a middle school in Guangzhou.Based on field investigation of classroom model,summarizes the horizontal,vertical and integrated visor combination form of various elevation,and the software simulation,daylighting variables for the correlation analysis,average daylight factor was discussed and the relationship between the total plate area fitting,and average daylight factor and plate of the relationship between the rotation Angle.Finally,the paper analyzes the facade effect,shading effect and the quality of natural lighting in the model classroom from three aspects,and compares the influence of different combination forms of facade shading on the natural lighting environment in the classroom,so as to provide reference for the design of various combination forms of facade shading in teaching buildings.The main research work and achievements of this paper are as follows:1.The characteristics and problems of the natural lighting environment of the middle school teaching buildings in Guangzhou under the climatic conditions are analyzed and summarized through the field research and the actual measurement of the classroom natural lighting.2.Based on the classroom model of field research,various facade forms of horizontal,vertical and comprehensive sunshade combination are summarized,and software simulation is carried out to obtain the fitting formula of the relation between the average value of daylighting coefficient and the total panel area,and the relation between the average value of daylighting coefficient and the rotation Angle of the panel.3.From the aspects of facade effect,shading effect and natural lighting quality of model classroom,the combination of horizontal,vertical and comprehensive sunshade was adopted to analyze the elevation shading optimization scheme of the actual teaching building,so as to provide reference for the comparison and selection process of the design scheme of the elevation sunshade.
