Optimize green campus sustainable construction from users' perspective

The concept of sustainable and green campus construction plays a key role in the development of higher education institutions, and university campuses globally nowadays are continuing to focus on green campus construction. Through the comparative analysis of three representative green campus evaluation systems and the modern methods of protecting the campus environment, we found that the existing green campus "hardware" construction tends to be biased toward technical directions and ignores the subjective perceptions of the main users of the campus. By taking 11 campuses in China as examples, this study further demonstrated the close correlation between users' perceptions and the green campus physical environment construction. Research has shown that it is difficult to optimize the sustainable performance of a green campus if we do not pay attention to the dynamic relationship among the four main factors of the campus's physical environment (campus scale, spatial accessibility, spatial organization modes, and spatial diversity), which can directly affect users subjective perception and behaviors. This work provides targeted optimization strategies and operable suggestions for improving the sustainable capacity of globally green campus construction.
