Research On Energy Efficiency Of Small And Medium-size High-speed Railway Station Waiting Room In Cold Areas

In our contry, a large number of high-speed railway stations has been constructedand developed, and the hight-speed railway will become the main mode oftransportation in china. Even though there are huge differences between high-speedrailway and traditional railway, such as operation and management mode, the builthigh-speed railway stations is almost the same as the traditional one, and did not haveany new design conception. The Thermal comfort of Railway station’s waiting room,which as a common large space has consumed huge energy, is an important measureindicator of building performance. Therefore, conducting a passive building energyefficiency design that based on the thermal comfort is one of the best ways to solvethis serious problem.Firstly, got access to a large literature, and summarized the status and limitationsof these studies. Then select four typical small high-speed rail stations to conduct fieldresearch, and summarized the characteristics of high-speed rail station andshortcomings of its energy consumption in four aspects: analysis of flow line, spatialfunction, physical environment, and questionnaire.Secondly, proposed high-speed rail station standard model, as well as its primaryenergy consumption characteristics based on material query and field research.Simulated standard model’s indoor thermal comfort (PMV, PPD) with simulationsoftware ECOTECT, and simulated its energy value with simulation software eQuestafter reaching the standard in thermal comfort.Thirdly, conducted the transformation and research in standard model of thewaiting hall in three aspects:interior visual perception, graphic layout, andarchitectural space height by integrating analysis and simulation, and concluded twooptimal solutions of transformation. Then, using ECOTECT to simulate the indoorthermal comfort of two transformed plans. After reaching thermal comfort standards,then calculated the air conditioning energy consumption value of the waiting hall witheQuest. Using the computer-based simulation and parameter calculation to obtain thequantitative relationship of the feeling of space, thermal comfort as well as buildingenergy consumption.Fouthly, compared and analyzed standard model, PMV and energy values of twotransformed waiting hall models. Proposed the factors of building space design andheight spatial design effect on high-speed rail station building energy consumption,proposed energy-saving design methods of high-speed rail station building Proposed the optimal energy-saving design model of high-speed rail station andprovided design basis of future new construction and transformation of the high-speedrail station.Finally, using Tianjin Binhai North Station as an actual case to verify whether theenergy-saving design methods that have perposed in the former researches are usefulor not.
