In sustainable development, assessing existing buildings via the lens of Leadership in Energy and Environmental Design (LEED) standards provides critical insights into the efficiency of implemented environmental practices. This study aims to fill the knowledge gap regarding sustainable building trends in Saudi Arabia by analyzing six facilities awarded LEED 2009 credits. The goals are several: first, to find overall patterns in the environmentally friendly building practices used in these buildings; second, to compare and contrast how well they did in important LEED 2009 categories such as Sustainable Sites, Water Efficiency, Energy and Atmosphere, Material and Resources, Indoor Environmental Quality, Innovation, and Regional Priority Credits; and third, to explain the pros and cons of these practices. Significant advancements in water efficiency and indoor environmental quality across the studied facilities highlight the comprehensive analysis’s diverse approach to sustainability. However, the study also uncovers notable challenges, particularly in Material and Resources, indicating areas that necessitate further development. In conclusion, this research offers a detailed and nuanced understanding of the contemporary state of sustainable practices in Saudi Arabian buildings. It serves as a valuable resource for stakeholders in the construction and management sectors, promoting a more profound comprehension of sustainable building trends and encouraging further advancements in this evolving field.
