Research On The Influence Mechanism Of Atrium Space On Room Daylighting

The atrium is usually an important part of a large building,plays an important role in building function and building physical environment improvement.In recent years,the atrium space in building daylighting effect and its mechanism of become a hot research topic in academic circles.Because of the atrium space for building interior especially natural lighting atrium adjacent rooms in the play great effect at the same time,there are uneven illumination conditions,how to reduce the impact of light environment is not comfortable and the adjacent space uneven illumination,improve natural lighting quality and efficiency,to create a healthy indoor light,comfortable environment,become the focus of research in natural lighting atrium design.In the solution space Has important significance of court space the adjacent room daylighting problem for the sustainable development of modern architecture.This paper focuses on the influence mechanism of the atrium space adjacent room daylighting,research and design means of optimization and on this basis.First of all,through the laboratory test and the computer of the atrium space adjacent room daylighting simulation,select the atrium type.The lighting coefficient measurement of the four typical scale model in the actual part of artificial sky,according to the numerical test lighting system calculates its average daylight factor,including measurement equipment,measurement scale model the introduction and measurement process.Simulation by numerical simulation of computer simulation software Desktop Radiance on the computer.Secondly,the Desktop Radiance simulation results analysis and statistical processing,the atrium space room The average coefficient of lighting room and vertical lighting coefficient,the relationship between reflectivity and plane form.Third,to optimize the design of the atrium space adjacent to room light environment quality according to the results of simulation analysis,according to the experimental results,combined with the need of architectural design,optimization design is put forward corresponding strategies for different types of atrium space,including a reflector different forms of atrium adjacent room light environment quality optimization and vertical reflectivity,optimization of plane form.Through the study of the influence of adjacent room in atrium daylighting,proposed for the optimization of lighting design and related suggestions,provides reference for the research on the adjacent room of natural lighting for the design of atrium space optimization and atrium space,and the atrium of the adjacent room design and lighting design and other related standards,provide the basis for the perfection of the standards.
