The Research of Triadic Relation among Building Spaces, Lighting Comfort Level and Lighting Energy Consumption in High-speed Railway Station in China

Abstract

Recently, the Assessment Standard of Green Buildings in China requires that the green buildings not only can conserve energy, but also should provide a healthy and comfortable environment for the residents, so does to the lighting energy consumption and lighting comfort. Therefore, the main purpose of this paper is to analysis the relationship among the three factors, including the building space, lighting comfort level and the lighting energy consumption, taking the high-speed railway station as an example. We did the investigations of the artificial lighting luminous environment in 5 typical high- speed rail stations and conducted the lighting comfort vote and questionnaires on site to find out the lighting comfort demand curve at night. We also concluded the simplified models of those spaces and simulated the lighting environment and lighting energy consumptions by the software: Dialuxevo. According to the lighting comfort level we investigated, the research group adjusted the lighting design, lighting source and even architectural space in the simulation. Aimed at the optimized lighting quantity and quality, an improved designing method was put forward.
