In line with global trends towards energy efficiency, Dubai's Government introduced Al Sa'fat Green Building Rating System (GBRS) to reduce the energy intensity of its building sector. This study presents the first comprehensive evaluation of Al Sa'fat with emphasis on building energy performance, shedding light on its effectiveness, limitations, and techno-economic potential. Following a comparison of Al Sa'fat to international and regional GBRSs, a detailed energy-efficiency analysis is conducted using building performance simulations applied to local residential and commercial building archetypes. The benefits of adopting Al Sa'fat at the urban scale are then estimated using a macro techno-economic analysis. Results confirm the potential of Al Sa'fat in curbing current consumption patterns with energy savings ranging from 22% for hotel buildings to 63% for single-family villas. The anticipated monetary savings from adopting Al Sa'fat in Dubai are equally significant and could exceed USD 100 Billion over the next 25 years. Finally, recommendations are made to overcome critical limitations of Al Sa'fat, including the minimal emphasis on water efficiency measures and limited differentiation between its current certification levels (i.e., bronze, silver, gold, and platinum), which could discourage building owners and developers from pursuing high certification levels.

根据全球能源效率趋势，迪拜政府引入了Al Sa'fat绿色建筑评级系统 (GBRS)，以降低其建筑部门的能源强度。本研究首次对 Al Sa'fat 进行综合评估，重点是建筑能源性能，阐明其有效性、局限性和技术经济潜力。在将 Al Sa'fat 与国际和区域 GBRS 进行比较之后，使用适用于当地住宅和商业建筑原型的建筑性能模拟进行了详细的能源效率分析。然后使用宏观技术经济分析来估计在城市范围内采用Al Sa'fat的好处。结果证实了Al Sa'fat的潜力在遏制当前的消费模式方面，节能范围从酒店建筑的 22% 到独栋别墅的 63%。在迪拜采用Al Sa'fat的预期资金节省同样显着，在未来 25 年内可能超过 1000 亿美元。最后，提出了克服Al Sa'fat 的关键限制的建议，包括极少强调节水措施以及其当前认证级别（即铜、银、金和白金）之间的有限差异，这可能会阻碍建筑业主和追求高认证水平的开发人员。
