Research On The Features Of Natural Lighting And Optimization Of Spatial Size In Building Corridor

In the existing buildings with large layout of interior corridors,the natural lighting in corridors is usually neglected,resulting in the fact that even if there is good sunshine in the outdoor area,the use of artificial lighting for a long time to meet the requirements of the use is also in the corridor.Not only is the energy consumption serious,but it also has some negative effects on human visual comfort and psychological pleasure.Under the background of high attention to building energy saving and natural light utilization,the natural lighting environment problem of the building corridor needs to be studied and improved.Study on natural lighting based on characteristics of public buildings in Northern Corridor Space,numerical simulation and statistical analysis methods to study the relationship between the gallery space scale and lighting index,determined in the design gallery meet the critical scale of architectural design of natural lighting requirements,in order to design such construction methods and code revision are given clear advice.Firstly,in the literature review and research the basis of extensive research,the thesis analysises of building corridor function,spatial characteristics and the related theory of natural lighting design and standards;at the same time using the questionnaire survey and field test methods,natural lighting status investigation of different types of public buildings in the corridor,and the construction personnel subjective feelings,the problems of inductive analysis within the corridors of natural lighting problem and related indicators;determine the quality problem for the long line in the corridor lighting the most serious space layout,with its length index as the main research object,and simulation analysis provides the basis for the subsequent numerical model parameters.Secondly,according to the long straight line type within the gallery space "and" open end window "lighting room" two kinds of conventional building layout,extract the lighting quality of key parameters was simulated with Ecotect software,to fully grasp the relevant lighting data,through the analysis of mathematical statistics,obtained in the different lighting layout and size parameters under the influence of the relationship within the gallery space and lighting coefficient,and then determine the critical length of corridor space corresponding to different design parameters of two kinds of lighting in buildings.Based on the study of corridor space natural lighting characteristics and meet the analysis of lighting quality of the critical length,grasp the factors of building quality change rule and influence of corridor lighting,to provide advice and guidance for lighting design of buildings within the gallery of architectural design in the future,and to refine and perfect for the public building lighting standards provide the basis.
