Research On Daylighting Design Of College University Gymnasium Based On Parameterized Platform

The gymnasium is an important infrastructure of colleges and universities.It has the characteristics of "a large number" and "high frequency of use".Existing college gymnasiums have problems such as “extensive lighting design”,“obvious lighting defects”,“poor visual comfort”,and “excessive energy consumption of artificial lighting”.It is found through research that the causes of lighting problems include changes in daylight,the surrounding environment of the building,and the lighting arrangement.However,the reasonable daylighting design of the stadium and the full use of natural light can not only reduce the energy consumption of artificial lighting,but also provide users with a good indoor environment.For the stadium building,daylighting is more conducive to improving the level of sports training and competition.Level.The new version of the Standard for Daylighting Design of Building(GB50033-2013)puts forward requirements for stadium lighting indicators,which provides a reliable guarantee for improving the stadium daylighting quality.This article relies on the National Natural Science Foundation of China,"theoretical research on natural lighting design of schools and gyms based on multi-objective optimization analysis"(51578368),in order to achieve the requirements of the daylighting standards,improve the quality of daylighting,and carry out research on the design theory of daylighting in gymnasium.The main work of this paper is as follows:1.Investigate the architectural space information and lighting indicators(illumination,lighting factor,and uniformity of daylighting)of college gyms in Guangzhou,Wuhan,and Dalian.Summarize the current two types of skylights(centralized,uniformly dispersed)and three side windows(high,middle,and low)in the gymnasium of the university.2.Based on previous research and research data,combined with Design Code for Sports Building,a typical space model for a college gymnasium is proposed.Its plane size is rectangular 46 m × 70 m,the total competition area size is 38 m × 44 m,fixed stands on both sides,building height 18 m,roof section form is parallel,and defines the indoor interface material and characteristic data of the university gymnasium.3.Based on the above typical model,through the establishment of a parameterized platform,the daylighting simulation and analysis of the skylight and side window two lighting port forms in different areas,positions,and orientations of the lighting quantity and lighting quality trends.The relationship between the lighting port layout and indoor Illumination,Lighting Factor,Uniformity of Daylighting,and Daylight Glare Index was obtained under different lighting conditions.4.Based on the above research,obtain the optimal daylighting plan and the corresponding daylighting design index under typical spatial model conditions.Through the above work,the feasible operation process of the above-mentioned daylighting simulation content was researched,and the key nodes and applicable methods of the parameterized simulation calculation of the daylighting of the building at the stage of the architectural design scheme were proposed.The research results of this paper are intended to provide a certain reference for the theoretical research on the design of daylighting openings in gymnasiums of colleges and universities,and have certain theoretical significance for guiding the daylighting design of gymnasium,scientific inspection and evaluation of lighting quality,and improving the daylighting quality of gymnasium.
