铁路客站天然采光现状及优化设计研究

Investigation and Optimum Design for Daylighting of Railway Station

客站的天然采光对于室内环境有着重要影响,而大面积的透光围护结构往往又是建筑节能的薄弱环节,客站的采光设计需要在光和热之间寻求合理的平衡。课题组通过实测调研,掌握了现有客站的采光状况,分析确定了合理的采光需求;并利用计算机模拟技术,对光热综合考虑,从建筑总体节能和改善室内环境两方面对采光进行优化,从而为后续的客站设计提供了参考和指导。

Daylight has an important impact on the indoor environment of railway stations.As large area of transparent envelope is often the weak link for building energy efficiency,a reasonable balance between light and heat should be considered during daylighting design of railway stations.However,overall consideration of light and heat was rarely taken into account in current study,which could easily lead to poor light and thermal environment.By field measuring and research,the authors have learned the general situation of daylighting for the existing railway stations,and determine a reasonable demand for daylight.Based on computer simulation technology,the authors optimize daylighting to improve overall energy efficiency and indoor environment,which provides reference and design guidance for follow-up stations.
