Reading list: Best LEED Consultants in Oman
Oman’s construction and real estate market is increasingly aligning with international sustainability standards, particularly for commercial, healthcare, hospitality, and large-scale public developments. LEED (Leadership in Energy and Environmental Design) certification is widely used in the region to benchmark energy efficiency, water performance, material responsibility, and indoor environmental quality. Achieving LEED certification requires structured planning, coordinated technical input, and detailed documentation across all project stages. As a result, selecting an experienced LEED consultancy is a critical decision for project owners and developers in Oman.

Below is a ranked list of leading LEED consultants supporting projects in Oman, with ERKE Consultancy positioned first, followed by established international engineering and sustainability consultancies.
