Optimization Design of Railway Station Buildings Based on Dynamic Daylighting Simulation
Railway station buildings are characterized by expansive spaces,high passenger flow volumes,and continuous operation,resulting in significant lighting energy consumption within these buildings.Leveraging natural daylighting efficiently not only enhances indoor comfort but also helps in reducing the lighting energy consumption of the buildings.This study focuses on Ankangxi Railway Station to explore the dynamic daylighting effects of railway station buildings at various stages.The research used the parametric software Rhino for modeling and utilized the sDA index to measure the duration and spatial proportion of natural daylighting.Moreover,the UDI100-2000,50％was used to evaluate the duration and spatial satisfaction levels of effective natural illuminance,offering a comprehensive assessment of the daylighting performance of station buildings.The study revealed issues with the original daylighting design,including inadequate local illumination and poor overall daylighting uniformity in the waiting hall.In the optimization design employing side curtain wall lighting and skylight lighting,there emerged problems such as excessive regional illuminance.Therefore,the study proposed installing skylights in the center of the waiting hall to enhance daylighting uniformity and increasing the window-to-wall ratio of the side station building facade.While there is no significant enhancement as indicated by the sDA index,the comfortable illuminance duration in the elevated waiting area is substantially improved.
