Analysis Of Natural Ventilation Design In Large Space Of Railway Station

Generally, natural ventilation is a useful passive design method to improve thermal environment, especially in large space buildings. Taking Zhengzhou East Railway Station (Zhengzhou ERS) as an example, this paper discussed the natural ventilation of Zhengzhou ERS by comparing experimental test with simulation of Computational Fluid Dynamics (CFD), based on local climate characteristics. Then, combined with the Zhengzhou ERS model, optimized natural ventilation design was proposed by comparing the natural ventilation conditions of different types of roof forms. And some ideas and reference were provided to improve indoor thermal environment and passive energy-saving design for large-scale railway station buildings.
