Abstract: On the basis of the Assessment Standard for Green Building (GB/T 50378—2019), the development status of green building design research for metro station underground space in China is systematically reviewed. The influencing factors of green building design for metro stations are deconstructed from macro site planning, meso architectural design and micro spatial expression three dimensions. Then, combined with the objective technology and the subjective perception level, a calculation formula of the comprehensive weight and the total score of influencing factors over underground space green building design system is put forward. With a systematical summary of the green building design technology for metro station, this research expands the space culture expression of metro station, explores the design theory and method of underground space green building for metro station.
