Research On Thermal Environment Design Of Waiting Hall For Large-scale Railway Station Based On Space Volume

With the continuous growth of national economic strength,China’s railway industry has welcomed the opportunity of rapid development and promoted the construction of railway passenger stations at the same time.As an important transportation hub,the railway passenger station is closely related to the travel of many thousands of people.The size of the passengers’ activity space and the advantages and disadvantages of the environment directly affect the travelers’ traveling experience and the quality of the railway service.In addition,due to the pursuit of the landmark of the building and the spatial effect of indoor penetration,it is unavoidable that sometimes the railway passenger station which has built affects the thermal environment,building energy consumption,and building space volume of the waiting hall.Therefore,the research on the thermal environment design of the waiting hall for the railway passenger station has certain practical significance for improving the passenger’s travel quality and promoting the sustainable development.At the same time,it can provide some reference for the design,construction and reconstruction of the waiting hall for the railway passenger station in the future.Through consulting and analyzing a large number of documents about the space volume of the waiting hall of railway passenger station,it is found that the space design volume of our new large-scale railway station waiting hall is generally based on the demand of modeling,passenger flow and functional use,which may cause the building thermal environment to fail achieve the desired effect and also affects the energy-saving capacity of station.Then,we can understand the relevant parameters and indicators of indoor thermal environment,and make preliminary theoretical preparations for later field research and software simulation analysis by reviewing the relevant theoretical knowledge of thermal environment.Then in this paper,we choose two waiting halls of railway passenger station in Wuxi as an example,and use use the combination of field measurement and questionnaire survey to study the current situation of thermal environment and the general situation of building space volume in these two stations.Finally,we use software simulation to study the influence of building space design on the thermal environment of waiting hall from two aspects which include the building plane and height,and put forward the optimization strategy of thermal environment for large-scale railway waiting hall.
