Analysis And Optimization Of Indoor Light Environment In Typical Space Of Colleges And Universities

With the rapid development of China's cities,environmental and energy crisis continues to deepen.Classrooms,libraries and dormitories are typical spaces in school buildings and are the areas where artificial lighting and energy consumption are the most concentrated.Their building lighting and lighting energy saving are increasingly the focus of research.Natural lighting and artificial lighting are the main parts of the light environment that affect the classroom,dormitory and library,and the factors that affect the quality of the light environment are played by many aspects.Students' learning efficiency,physical and mental health and school energy consumption levels are affected by indoor light environmental quality.In this paper,through the comparison of measured results and evaluation methods,the paper puts forward the optimization strategy of optical environment in colleges and universities.This paper chooses the school typical space(classroom,dormitory and library)as the research object,combined with the human body to the light environment demand characteristic.Put forward the typical space light environment improvement measures,has reached the purpose of reducing lighting energy consumption.This paper mainly includes the following contents: First,the characteristics of classroom,dormitory and library light environment demand analysis,select the typical space,the use of field measurement and subjective research methods,the light environment assessment and status analysis;Secondly,based on the use of simulation The software will simulate the most unfavorable working conditions of the whole year and propose improvement measures.Then,the characteristics of light demand in the typical space are measured and evaluated,and the natural lighting situation in the room is improved by setting the shading and reflector.And to classrooms,for example,given the type of classroom lighting and layout optimization methods to reduce lighting energy consumption.In this paper,the field space and the subjective questionnaire survey of the typical space environment of the school,through the evaluation and analysis of the typical space of colleges and universities,put forward the optimization plan,the future of school construction and energy conservation has a certain reference.
