Study On Lighting Design Of College Classroom In Cold Regions

Teaching building is a major part of universities.Natural lighting is very important for teaching buildings.As of today,scholars at home and abroad have been fruitful for the study of natural lighting in teaching buildings.The results are mainly focused on increasing the amount of light in the room,improving the comfort of the indoor light environment,and the effects of natural light on the physiological and psychological effects of the users.However,little research has been done on the natural lighting of buildings in terms of building energy consumption.Based on the climate characteristics and the lighting requirements of the cold region,this paper takes the No.1 building of Beijing Architecture University as an example.Through the investigation of the present situation and the statistical study of meteorological data,the utilization rate of natural light in Beijing and the influence on lighting energy consumption are put forward.It is found that improving the utilization rate of natural lighting is the main energy consumption reduction in cold regions.On the basis of computer simulation,a method of optimizing lighting design for college classrooms in cold regions is put forward..
