| Natural lighting is a way to introduce natural light into the building to form a good indoor light environment.However,in recent years,the number of teaching buildings in colleges and universities has increased sharply,and the rapid construction on a large scale has caused serious natural lighting problems such as severe glare and uneven illumination in classrooms.Now,specifically for college classroom climate characters of natural light in different areas of the lighting research is insufficient,Hohhot area light ? climate zone,with abundant solar radiation resources,both from the perspective of energy conservation and consumer health point of view,the region of college teaching building daylighting to optimize classroom study should be given full attention.In this context,this paper firstly analyzes the characteristics of light climate in Hohhot area,determines the main influencing factors of natural lighting,selects the applicable simulation software and evaluation indexes,and comprehensively analyzes the theoretical knowledge related to natural lighting design by using the method of literature research,induction and comparative analysis.Secondly,through the field measurement and data analysis of 132 classrooms in colleges and universities in Hohhot area,a typical classroom model was established,and according to the results of illumination test and questionnaire survey,the problems of natural lighting in classrooms were found.Then through the simulation of Ecotect,Radiance and Daysim software,the influence law of dynamic natural lighting influencing factors such as the geometry of the classroom space,the form of light Windows,the arrangement of side Windows and the shading was explored.Finally,the dynamic natural lighting optimization design of a typical classroom is simulated according to the influence law and the optimization effect is verified.In order to provide some references and Suggestions for the future optimization design of natural lighting in university classrooms.The main conclusions of this study are as follows:First,this study summarized and analyzed the characteristics of light climate in Hohhot area,summarized the main influencing factors of natural lighting in the classroom,and screened out the appropriate dynamic natural simulation software and evaluation indicators.Second,this study analyzes the existing problems of natural lighting in collegeclassrooms in Hohhot,tests the data of classroom spatial morphology and analyzes the characteristics of the data,and establishes a typical model of college classrooms in Hohhot.Thirdly,from the perspective of the dynamic natural lighting quality of the classroom throughout the year,this study explores the influence rules of the main factors affecting natural lighting.The dynamic natural lighting of the classroom was optimized and verified from four aspects: the way of shading the classroom,the geometric dimension of the classroom space,the form of lighting window and the arrangement of side Windows.Based on the law of the main influencing factors,this study proposes the corresponding optimization design,which can enrich the theoretical system of natural light environment optimization of university classrooms.In addition,the natural lighting design of the classrooms in the same light climate area can be given as a guidance,so that the natural lighting and space design of the huhhot area university classrooms in the organic combination of natural lighting and space design,has a certain theoretical and practical significance.The innovation points of this study are as follows: based on the characteristics of regional light climate,the optimized design of natural lighting in the classroom is studied;Through field research,the natural lighting environment in university classrooms in Hohhot area was systematically tested,and its characteristics were summarized.Dynamic simulation software and dynamic evaluation index were used to simulate,analyze and optimize the design of year-round natural lighting in university classrooms. |
