Evaluating Green Campus Environments in Chinese Universities from Subjective Perceptions: A Textual Semantic and Importance-Performance Analysis Through a Satisfaction Survey

University campuses play a crucial role in sustainable development; however, the current green campus evaluation systems tend to focus primarily on the physical environment and building technology, often overlooking user perception and the impact of these factors on the execution of green campus strategies. Starting with an examination of the connotation and evolution of green campuses, we derived relevant indicators of campus subjective perceptions from both domestic and international green campus evaluation systems. We collected user feedback through satisfaction questionnaires and text data on the green campuses of nine representative Chinese universities. Factor analysis was used to establish the correlations between campus planning and subjective perceptions across six key areas. This research applied importance-performance analysis (IPA) to assess the prioritization of each green campus indicator, integrating it with textual semantic analysis to better understand the perceptions and attitudes of campus users toward green campus development. The findings suggest that the objectives of a green campus cannot be fully achieved using only technical or physical evaluation criteria. Instead, combining subjective feedback with quantitative indicators forms the foundation for effective strategy development. This study also found that users were more concerned about the design of details related to learning, living, entertainment, and recreation than the broader green campus planning decisions made by planners and decision-makers. Focusing on user perception and balancing scientific planning with public participation can help achieve the ultimate goal of green campus planning and design, adhering to a human-centered approach.
