Abstract: The author analyzes the construction and operation status of underground space/rail transit works and believes that great progress has been made in the energy saving, carbon emission reduction, environment protection and lowcarbon, economical and sustainable development of underground space/rail transit works. Due to the shortage of natural resources, energy saving and environment protection of underground space/rail transit works should be strengthened. The author makes 4 suggestion on energy saving and environment protection, including: 1) Developing solar energy power generation step by step; 2) Popularizing intelligent LED light and other new types of lights; 3) Adopting other tunnel lighting technology, such as outtunnel lightness testing technology, a suit of tunnel lighting and energy saving technology and new type of LED lighting adjusting technology; 4) Developing of other energy saving and environment protection technologies, such as solar power lighting system, new type of superenergysaving lights, natural illumination and intelligent lighting technologies. The author also gives some examples, such as the largest solar energy power generating and lowenergyconsuming building in Wuxi and harmless policies and energy saving technologies of Hongqiao transit center, so as to provide references for the construction of tunnels, Metro works and underground space.
