摘　　要：随着我国高寒地区铁路站房的大量兴建,有必要探索适合的建筑节能技术以实现铁路站房的可持续发展。本文以林芝站为例,采用计算机模拟的方法,分析了建筑冬季防风策略以及围护结构保温和窗墙比与全年能耗的定量关系。结果发现,入口门斗设置外门斗,检票口不设门斗的方式可以有效减少冬季室内渗风,同时改善围护结构热工性能可以明显提升冬季节能效果,权衡保温厚度与收益给出最合适的保温材料及厚度。论文提出了适应高寒气候的铁路站房最佳节能设计参数,为同类型建筑节能设计提供了理论依据和数据参考。With the widespread construction of railway station buildings in China s high-cold regions,it is necessary to explore suitable building energy-saving technologies to realize the sustainable development of railway station buildings.Taking Nyingchi station as an example,this paper analyzes the windproof strategies of buildings in winter and the quantitative relationship between the thermal insulation of the enclosure structure and window-to-wall ratio and annual energy consumption by means of computer simulation.The results show that the way of provision of an outer foyer at the entrance and no foyer at the ticket gate can effectively reduce the indoor air infiltration in winter,and improving the thermal performance of the envelope structure can obviously improve the energy-saving effect in winter.Moreover,the most suitable thermal insulation material and thickness are determined by weighing the insulation thickness and benefits.This paper proposes the optimal energy-saving design parameters of railway station buildings suitable for the high-cold climate conditions,which provides theoretical basis and data reference for energy-saving design of the same type of buildings.
