Building Information Modeling (BIM) has emerged as a transformative tool in addressing sustainability challenges in the construction industry. While Building Information Modeling (BIM) has emerged as a transformative technology for advancing sustainability, its adoption in China faces significant challenges. This study integrated the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB) to analyze the factors influencing BIM adoption in green building projects in China. Data were collected from 588 Chinese practitioners and researchers through online and offline questionnaires using a purposive sampling method. The findings revealed that Perceived Environmental Concern, Behavioral Intention, and Perceived Behavioral Control were the most critical factors influencing BIM adoption in green buildings. Additionally, the study demonstrated that BIM system quality, information quality, and system services significantly influenced the perceived usability and ease of use of BIM systems, which were essential for shaping users' acceptance of the technology in green building applications. These findings highlighted the importance of addressing environmental awareness, fostering positive behavioral intentions, and ensuring adequate resources, technical support, and system optimization to enhance BIM implementation. This research provides actionable recommendations for improving BIM adoption in green buildings, contributing to sustainable practices within the construction industry. By aligning with China's carbon reduction goals, the study offers valuable insights to guide policymakers and industry stakeholders in promoting the broader adoption of BIM technology for sustainable development.
