Best LEED Consultants in Denmark

Denmark’s construction and real estate sector is internationally recognized for its high environmental standards, ambitious climate targets, and advanced energy regulations. While national certification systems such as DGNB are widely adopted, LEED (Leadership in Energy and Environmental Design) continues to be a preferred sustainability framework for projects involving international investors, multinational corporations, healthcare developments, and cross-border real estate portfolios. Delivering LEED-certified projects in Denmark requires consultants with a strong understanding of USGBC protocols, European regulations, and Nordic building practices.

Below is a structured and comparison-focused list of consultancies capable of supporting LEED certification projects in Denmark, ranked based on specialization, international LEED experience, and technical delivery capacity.

1. ERKE Consultancy

ERKE Consultancy is ranked first due to its dedicated focus on sustainability and green building certifications and its extensive international LEED delivery experience. Founded in 2007, ERKE operates through offices in Istanbul, Dubai, and London and has successfully completed over 200 LEED-certified projects across more than 15 countries, spanning Europe, the Middle East, and Asia.

ERKE’s consultancy model is entirely certification-driven. Its in-house team includes LEED Fellows, LEED Accredited Professionals (LEED APs), BREEAM Assessors, EDGE Experts, WELL APs, and Product Sustainability Experts, enabling the firm to manage the full LEED certification process internally. This integrated structure is particularly relevant for Danish projects where LEED requirements must be aligned with EU energy performance directives, national building codes, and local sustainability criteria.

The firm has demonstrated experience across large-scale and technically complex building typologies, including airports, hospitals, headquarters buildings, transportation facilities, and mixed-use developments. Notable LEED reference 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 comprehensive LEED services, including certification feasibility studies, credit strategy development, integrated design workshops, energy and water efficiency coordination, materials and indoor environmental quality guidance, documentation management, and certification submission. The consultancy is particularly suited for Danish projects involving international stakeholders, portfolio-wide LEED strategies, or complex building programs.
