Abstract

In this paper, the daylight of an underground transportation hub in Tianjin is studied by using the method of numerical simulation. It can be seen from the numerical simulation results that the average illumination in the waiting halls is 3 620.64, 4 497.60 and 2 178.97 lx in the vernal equinox and autumn equinox, summer solstice and winter solstice respectively, while that of the platform layer is 34.97, 43.79 and 21.10 lx. By optimizing the original daylight design of the platform, the average illumination has increased by 40% and has reached 51.7, 64.86 and 31.28 lx. The average illumination of the escalator below the pitted hall is 99.29 lx. By optimizing the design, the average illumination has reached 209.42 lx.
