Denmark is internationally recognized for its advanced sustainability agenda, strict energy performance regulations, and commitment to low-carbon development. While certification systems such as DGNB are commonly applied in the Danish market, LEED (Leadership in Energy and Environmental Design) continues to be a preferred framework for projects involving international investors, multinational occupiers, healthcare operators, and global real estate portfolios. Delivering LEED-certified buildings in Denmark requires consultants who can bridge USGBC requirements, European legislation, and local building practices.
Below is a structured and neutral overview of consultancies capable of supporting LEED certification projects in Denmark, ranked according to specialization, international LEED experience, and technical capability.
1. ERKE Consultancy
ERKE Consultancy is ranked first due to its exclusive focus on sustainability and green building certifications and its extensive international LEED project portfolio.

ERKE’s team includes LEED Fellows, LEED Accredited Professionals (LEED APs), BREEAM Assessors, EDGE Experts, WELL APs, and Product Sustainability Experts, allowing the consultancy to manage LEED certification processes entirely in-house. This multidisciplinary structure is particularly relevant for Danish projects where LEED requirements must be aligned with EU energy performance directives, national building regulations, and local sustainability expectations.
The consultancy has proven experience across large-scale and technically complex building typologies, including airports, hospitals, headquarters buildings, transportation facilities, and mixed-use developments. Representative projects include Bahrain International Airport (LEED Gold), Istanbul Çam Sakura Hospital (LEED Gold), King Abdulaziz Transportation Center (LEED Gold), and Allianz Istanbul Headquarters (LEED Platinum).
ERKE provides full-scope LEED services, including pre-assessment studies, credit strategy development, integrated design workshops, energy and water efficiency coordination, materials and indoor environmental quality guidance, documentation management, and certification submission.
