The Study Of Ordinary Classroom Daylight Based On The Form Of Single-sided Window And Rectangular Plane In Beijing

Nowadays,with the excessive intervention of artificial lighting technology in the classroom,the depth of the classroom has been designed more and more deeper.As a result,the daylight near the inner vertical wall of the classroom is often insufficient,which has a negative impact on the vision health of users.At the same time,excessive dependence on artificial lighting also increases the energy consumption of the classroom.The corridor layout is a common layout form in the ordinary one-sided window classroom in Colleges and universities.Where the poor daylight in the classroom are generally located in the place far away from the window.How to improve the daylight level of this location has become the key to improve the overall daylight effect of the single-sided window classroom.After the simulation and analysis of various improvement measures,the author proposes that the arc reflector is a way to improve the daylight level in classroom.The main research contents are as follows:1.Based on the field survey of some university classrooms in Beijing,the general daylight situation of the single window classroom in the area is mastered,and the main space dimensions of these classrooms are checked with the current national standards and specifications,and the possible reasons behind the existing lack of daylight are found and suggestions for daylight improvement are put forward.2.Based on the building model of classroom space,the common daylight improvement measures are preset respectively,that is,increasing the floor height,changing the inclination of the ceiling,adding a sunshade(with reflective effect),as well as the arc-shaped reflector designed by the author.Then through the daylight environment simulation software to simulate and analyze these four kinds of daylight improvement measures,and to evaluate and summarize the daylight impact of various measures.The simulation analysis and comparative study show that the arc reflector can improve the indoor daylight level in sunny,cloudy and cloudy days.3.The arc reflector is applied to the daylight optimization design of some research classrooms,that is,the improvement of daylight environment.On the basis of mastering the space and structure of the original classroom,the original classroom model is established,and arc reflectors are installed.Through the daylight simulation andcomparative study before and after the installation,further verify the effectiveness of the daylight improvement measures.
