Natural Lighting Design Strategy Of University Teaching Building In Xi’an

With the scientific development of colleges and universities and the expansion of enrollment,teaching buildings have ushered in a new construction climax,and people are paying more and more attention to the environmental quality design of teaching spaces in colleges and universities.The teaching building,as a place to carry most teaching activities,its natural lighting design plays an important role in improving the indoor light environment quality and reducing building energy consumption.The traditional teaching building relies too much on artificial lighting,and there are many deficiencies in the natural lighting design,which directly affects the physical and mental health and learning quality of students.In the era of rapid information development,computer simulation technology is widely used in the field of architectural design.Its informational,visual,and refined features can play a unique advantage in natural lighting design and solve the deficiencies in natural lighting design of traditional teaching buildings.And drawbacks.This article takes the natural lighting of the teaching building of colleges and universities in Xi’an area as the research object.Based on the research of related design theory,after conducting on-the-spot investigations on the teaching building architectures of many colleges and universities in Xi’an area,the paper summarizes and concludes the teaching in Xi’an The current characteristics of the building’s lighting.Three representative typical teaching buildings were selected as test research cases,using the methods of data collection,on-site investigation and testing,and scale data analysis,combined with the characteristics of light and climate in Xi’an,to summarize the current daylighting design of the teaching buildings in Xi’an The main problem.Then use Ecotect and Radiance light environment simulation software to simulate and analyze the influencing factors of natural lighting in the teaching building in three aspects: overall planning,space design,and lighting components.Finally,according to the influencing factors of the natural lighting of the teaching building in Xi’an obtained from the above research,a design strategy suitable for the natural lighting of the teaching building in Xi’an is proposed.According to the summarized lighting design strategy combined with the light environment analysis software,the lighting designtransformation and optimization design of one of the typical teaching building cases were carried out,and the necessity and feasibility of the lighting strategy were verified through the comparison of the optimized data.The main research work and achievements of this paper are:1)Through the investigation and testing of the light environment of three typical university teaching buildings in Xi’an,the status quo and existing problems of natural lighting design of teaching buildings in Xi’an are analyzed and summarized;2)Through simulation analysis,elaborated the influence law of natural lighting design factors of the teaching building of colleges and universities in Xi’an area;3)Propose a natural lighting design strategy suitable for college teaching buildings in Xi’an and conduct an empirical optimization design;...
