As a significant attempt to save energy and minimize environmental pollution, green building has aroused public attention worldwide. Promoting green building with less time and high quality is the primary target in many countries. Although critical success factors that influence green building promotion have been identified in previous studies, there is no consensus reached on the factors and their significance. To fill the gap, this research aims to provide a systematic literature review on the critical success factors in promoting green buildings and further rank the factors quantitatively. Relevant literature was selected based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Forty critical success factors in green building promotion were identified from previous studies, and the meta-analysis was conducted to rank them based on the synthetical means. The results indicate that the roles of stakeholders and government are vital in green building promotion. The commitment, cooperation, and early involvement of stakeholders are essential in the green building practice, and the adequate incentives and mandatory requirements from the government are also significant. This study contributes to the existing green building knowledge body by deepening an explicit and in-depth understanding of critical success factors in green building promotion through a quantitative approach. Moreover, it provides suggestions for the government and practitioners, which is highly beneficial to making decisions.
