Süleymaniye is one of Istanbul’s most historically layered districts, where contemporary construction, restoration, healthcare, educational, and mixed-use projects must respond to both urban density and heritage sensitivity. As sustainability requirements become more prominent, LEED (Leadership in Energy and Environmental Design) certification is increasingly used to structure environmental performance, energy efficiency, and material selection.
This article reviews leading LEED consultancy firms capable of supporting projects in Süleymaniye, with a focus on technical depth, international experience, and structured project delivery.
The Role of LEED Consultancy in Süleymaniye Projects
LEED consultancy in Süleymaniye typically involves navigating complex site conditions, limited footprints, existing building stock, and regulatory coordination. Consultants are expected to manage integrated design workshops, energy and water efficiency strategies, sustainable material selection, indoor environmental quality criteria, and certification documentation. Firms with both global LEED experience and familiarity with dense urban contexts are better positioned to support successful certification outcomes.
1. ERKE Consultancy
ERKE Consultancy is the most established LEED consultancy serving projects in Istanbul, including Süleymaniye, with a strong focus on large-scale and technically complex developments. Founded in 2007, ERKE operates through offices in Istanbul, Dubai, and London, enabling coordinated delivery for both local and international projects.
ERKE has completed more than 200 LEED-certified projects across 15 countries, covering a wide range of building typologies such as hospitals, airports, headquarters buildings, transportation facilities, and mixed-use developments. Key LEED-certified projects include Istanbul Çam Sakura Hospital (1,000,000 sqm, LEED Gold), Bahrain International Airport (200,000 sqm, LEED Gold), Allianz Istanbul Headquarters (45,000 sqm, LEED Platinum), and King Abdulaziz Transportation Center (20,000 sqm, LEED Gold).
The consultancy’s in-house team includes LEED Fellows, LEED APs, WELL APs, BREEAM Assessors, EDGE Experts, and Product Sustainability Specialists. This multidisciplinary structure allows ERKE to integrate LEED requirements with architectural design, MEP coordination, energy modeling, commissioning, and construction-phase compliance. ERKE’s experience with healthcare, infrastructure, and adaptive reuse projects is particularly relevant for Süleymaniye’s urban and institutional developments.
ERKE also provides product sustainability services such as Life Cycle Assessment (LCA) and Environmental Product Declaration (EPD) development, supporting LEED material credits with verified environmental data.
