寒冷地区既有火车站低碳更新适配技术研究

Study on low-carbon renewal adaptation technology of existing railway stations in cold areas

针对寒冷地区既有火车站建筑性能差、围护结构能耗大的现状和低碳更新要求,对既有火车站低碳更新适配技术进行分析,通过Rhino/Grasshopper平台、Honeybee建筑能耗模拟软件对围护结构更新前后的能耗进行模拟,利用正交试验方法对不同更新参数的能耗结果进行优化,得到围护结构能耗影响因素大小排序及低碳更新最优技术参数,分析车站低碳更新的减碳效果,所得结论可为同类既有火车站低碳更新提供参考。

In view of the low performance of existing railway stations in cold regions,high energy consumption of envelope and low-carbon renewal requirements,this paper analyzes the adaptation technology of low-carbon renewal of existing railway stations,simulates the energy consumption of envelope before and after renewal through Rhino/Grasshopper platform and Honeybee building energy consumption simulation software,optimizes the energy consumption results of different renewal parameters by orthogonal test method,obtains the ranking of influencing factors of energy consumption of envelope and the optimal technical parameters of low-carbon renewal,and analyzes the carbon reduction effect of low-carbon renewal of stations.The conclusions can provide a reference for low-carbon renewal of similar existing railway stations.
