大型高铁站房天窗采光优化设计研究——以天津站为例

A Study on the Daylighting Design of Large High-speed Railway Station:A Case Study of Tianjin Station

以天津站为例,利用IES数值模拟软件对高铁站房的天然采光优化设计进行了研究,通过前期的调研与数值模拟优化,得到了天津站天窗采光口布局的最优方案.与原方案相比,采光口面积由原来的3 110 m^2降至1 036 m^2,室内天然光照度达到1 023.95 lx,符合国家标准;在采光满足国家标准的同时,大大降低了围护结构的传热量.

In this paper, Tianjin high-speed railway station is taken as an example to study the daylighting design of stationby using the IES simulation software. Through the methods of preliminary investigation and numerical simulationoptimization, the authors got the optimal scheme of the skylight layout of Tianjin high-speed railway station. Compared withthe primary scheme, the area of skylight declined from 3 110m2to 1 036m2, and the illuminance of lighting indoor reachedto 1 023.95 lx, which can meet the national standard. At the same time, the heating transfer of envelop enclosure is reducedgreatly.
