Energy-Saving Design Strategy Of High-Speed Railway Station Enclosure System In Cold Area

In the context of the rapid expansion of cities in China and the close and coordinated development of various cities,the construction of high-speed railways has entered a stage of high-speed development.Among them,the high-speed railway station is the most important part of the high-speed railway system.It is a typical large-space public building.To multiple functions such as transportation hubs,city image displays,and city landmarks.With the gradual increase in the construction of high-speed rail station buildings and the gradual increase in people's requirements for energy-saving,environmentally friendly and sustainable development,high-speed rail stations have high utilization rates and large energy consumption,and the problem of lack of energy-saving design urgently needs to be resolved.According to research by relevant scholars in China,the envelope system accounts for the largest proportion of building energy loss factors in cold areas,reaching 70%-80%.Therefore,the design of the building envelope system is the focus of energy-saving building design.In this paper,the cold area in China is selected as the research scope,and the envelope system of the high-speed railway station is taken as the research object.From the overall design of the envelope structure of the high-speed railway station in the cold area,the design of the external envelope structure,and the design of the internal envelope structure,the balance point of reducing the energy consumption and use comfort of the cold area high-speed railway station is explored,and the envelope system of the high-speed railway station in the cold area Energy-saving design strategy.The first chapter outlines the research background and purpose of this paper,clarifies the research ideas and simulation methods of this paper to find the energy-saving design strategy of the enclosing structure of cold area high-speed railway station combined with the light and heat comfortable environment,and lists the research framework.The second chapter is an analysis of the characteristics of cold regions and related energy-saving concepts of building envelope systems in cold regions,and explores its energy-saving potential.The third chapter is the investigation of high-speed railway stations in cold regions and the analysis of the factors affecting the energy consumption of high-speed railway stations in cold regions.Summarize the characteristics of high-speed railway stations and their surrounding structures in cold regions of China,explore the key factors affecting their energy consumption and summarize the cold-region high-speed railway station's surrounding structures from: overall design,external surrounding structure design,and internalsurrounding structure design.Each level is the main point of energy-saving design from the perspective.The fourth chapter is the energy consumption simulation based on the influencing factors summarized in the previous chapter.The fifth chapter is to combine the relevant data and the simulation results of the previous chapter,and propose the corresponding energy-saving design strategy of the high-speed railway station enclosure system in cold areas from the overall,external and internal levels.
