High-speed Railway Station Building's Energy-efficient And Carbon-reduction Research On Early-stage Design

In recent years,with the continuous expansion of high-speed railway's coverage and deepening of coverage site,high-speed railway station,as a typical large-space public building,has been actively constructed throughout the country.The energy consumption,carbon emission and leading role of high-speed railway stations are attracting more and more attention of our society.Based on architectural early-stage design,from the perspective of energy-efficient and carbon-reduction,this thesis explores related design strategy of high-speed railway station building,aiming to effectively control the energy consumption and carbon emission through scheme design.Firstly,from railway station's design to high-speed railway station building's design,from large space building's energy consumption to high-speed railway station building's energy consumption,meanwhile,paying attention to carbon emission factors of high-speed railway station building,conduct theoretical research with case analysis.Secondly,through practical investigation of high-speed railway stations,finding different problems related to building's energy consumption and carbon emission at early-stage design,put forward energy-efficient and carbon-reduction potential.Then,based on the theoretical and practical research,energy-efficient and carbon-reduction strategies at early-stage design are put forward including form scale,spatial combination,details,operation controlling,building size and station square;And take Tianjin West Railway Station as the research object to carry out quantitative simulation of energy consumption and carbon emission,verifying the strategy effect.Finally,take Tianjin West Railway Station as an example to discuss energy-efficient and carbon-reduction strategies that may be integrated in early-stage design,generate research scheme,with the quantitative comparison between existing station and research scheme to verify energy-efficient and carbon-reduction effect.Through theoretical and practical research,qualitative analysis and quantitative calculation,this thesis proposes high-speed railway station building's energy-efficient and carbon-reduction potential and systematic strategies on architectural early-stage design,and with the help of parametric design tools and computer simulation,carry out design optimization and effect evaluation.The thesis shows that,high-speed railway station building's energy-efficient and carbon-reduction design at early-stagehas great potential and obvious effect.It can not only effectively reduce energy consumption and carbon emissions of the building life cycle,but also have reference value for other large space buildings.In the new era,it has special demonstration meaning and driving action.
