English abstract
The requirement for environmentally friendly methods of construction has increased the
demand for regionally customized rating systems. In Oman, the prevailing use of the LEED rating
system has shown limitations in addressing the unique economic, environmental and social needs
of the country. This study introduces the utilization of Omani Developed Sustainability Rating
System (ODRS) as a more accurate and contextually relevant tool for evaluating the current
sustainability practice of construction projects in Oman.
Through a comprehensive evaluation of 25 case studies encompassing governmental, semigovernmental, and private projects, this research highlights the varying acceptance and
effectiveness of sustainable practices across different financial ranges and project types. The
findings indicate that projects with higher budgets, such as the PDO Ras Al Hamra housing project
(sustainability rate of 81%) and the OAAM project of Royal Court Affairs (sustainability rate of
88%), achieved superior sustainability scores compared to smaller, private projects and some
governmental projects.
A mixed-method approach combining quantitative analysis and qualitative stakeholder
interviews was employed. Quantitative data were analyzed using R Studio software to evaluate
sustainability indicators, while interviews provided insights into specific risk factors and
challenges faced by stakeholders. The study also identified barriers that hinders sustainable
construction, including waste management, resource efficiency, regulatory constraints, and
economic priorities.
The comparison between LEED certified projects and (ODRS) scores for the same projects
underscored the discrepancies in sustainability assessments to approximately (10-15%),
emphasizing the need for a localized system. The ODRS was shown to offer a more accurate
reflection of Oman's sustainability criteria, driving more relevant and impactful sustainability
initiatives.
This research concludes that while the ODRS provides a robust framework for
sustainability assessment in Oman, further enhancements are necessary. Recommendations
include expanding stakeholder engagement, increasing the diversity of case studies, and
implementing continuous monitoring and evaluation of the ODRS. Addressing these aspects can significantly advance sustainable construction practices in Oman, ensuring alignment with the country's specific needs and fostering a more resilient built environment.
