摘　　要：针对重庆沙坪坝交通枢纽项目地下空间进行了天然采光方案优化研究。结合建筑特点确定了天然采光形式,在此基础上利用数值模拟手段确定了满足天然采光所需的天窗比和单个天窗大小,并结合照明系统进行了能耗和经济性分析,从而得到最优化的设计方案,并为其他项目的地下交通空间天然采光设计提供了参考和指导。This paper studies the optimization scheme of daylighting in underground space of Shapingba Transportation Hub in Chongqing. According to the characteristics of the building,the form of daylighting is determined. Based on the above,the skylight ratio and the size of a single skylight is determined by means of numerical simulation method. Then energy consumption and economy are analyzed,combining with current lighting system,and the optimization scheme is obtained. It provides reference and guidance for the design of daylighting in the underground transportation space of other projects.
