Abstract: Based on engineering practices, this article analyzed the influence of thermal performance of building envelope of the elevated railway station on its indoor thermal and lighting environment, and its energy consumption of air-conditioning during summer through field measurement, mechanism analysis and numerical simulation. This article also explored energy-saving strategies of urban elevated railway station in Guangzhou, and optimized the heat gain coefficient of exterior windows, window-to-wall area ratio, heat transfer coefficient of exterior windows, exterior wall and roof, and effective ventilation area of exterior windows. The conclusion of this article could provide guidance or reference for future design of elevated railway station halls.

Key words: urban elevated railway station hall, thermal performance of building envelope, thermal environment in transitional seasons, lighting environment, energy consumption of air conditioning
