Study On Natural Lighting Design Strategy Of High-Speed Railway Station Waiting Space In Cold Region

With the rapid development of railway industry,the waiting space of high-speed railway station plays a more and more important role in social and economic life.As an important part of the high-speed railway station,the waiting space has been greatly improved in terms of space quality and physical environment.Combined with green building performance simulation technology,the full use of natural lighting has become a trend of social development.The cold region has obvious regional climate characteristics,the duration of sunshine in winter is long,and the winter duration is long.Therefore,it is of great significance to introduce natural lighting into the waiting space of high-speed railway station by combining parameterized modeling and green building performance simulation technology.In the survey of the waiting space,it is found that if the use of natural lighting is not good,it will bring a series of problems such as too bright illumination and uneven illumination.Therefore,how to make full use of natural lighting to provide passengers with a comfortable and healthy waiting space light environment has become an urgent problem to be solved.Based on Rhinoceros&Grasshopper modeling platform,combined with Diva,Radiance,DaySim and other simulation engines,this paper takes the combination of the design of the waiting space and the design of the light environment of the high-speed railway station in the cold region as the starting point of the research.By referring to relevant theoretical works and excellent cases,To explore,study and summarize the natural light environment in the waiting space of high-speed railway station.At the same time,to the west station of Harbin,changchun,Harbin station,west railway station,shenyang north station to field survey and questionnaire survey,and on this basis,the use of green building performance simulation technology to simulate the waiting space dynamic lighting,from the aspects of natural lighting to the waiting room daylighting design puts forward the design strategy,at the same time of meet the functional requirements to improve the quality of waiting space,To create a visual pleasure,high efficiency and energy saving light environment for the waiting space,to provide reference for the waiting space natural lighting digital design practice.
