The implementation of green buildings is widely regarded as a primary solution for optimizing fuel consumption in the construction and housing sector. Through an examination of relevant research literature, the most prominent hindrances to the implementation and proliferation of green buildings in Saudi Arabia were identified. Furthermore, the present study employed the Fuzzy Decision-making Trial and Evaluation Laboratory (FDEMATE) to prioritize the aforementioned obstacles via the Fuzzy Analytic Network Process (FANP), while the Decision Super model was utilized. The findings indicate that the primary criteria section identified marketing barriers as the most significant obstacle, with a weight of 0.213, followed by risk and cost barriers with a weight of 0.207, knowledge and information barriers with a weight of 0.195, government-related barriers with a weight of 0.193 and human resources barriers with a weight of 0.192, respectively, ranked from first to fifth. According to the study's analysis, marketing obstacles carried the most weight, followed by risk and cost obstacles, government obstacles, knowledge and information obstacles and resources obstacles. The country has not adequately promoted green building technology. According to experts in the field, this is the greatest obstacle to implementing environmentally friendly building practices.
