Belgium’s commercial and institutional construction market increasingly integrates sustainability targets driven by EU regulations, corporate ESG frameworks, and international investor requirements. LEED (Leadership in Energy and Environmental Design) remains one of the most widely adopted global certification systems for projects that require transparent, third-party verification of environmental performance. While Belgian energy and environmental regulations establish baseline compliance, LEED certification provides a structured methodology to assess efficiency, material use, indoor environmental quality, and long-term operational performance.
Delivering a successful LEED-certified project typically requires experienced consultancy support capable of managing strategy, technical coordination, and documentation. Below is a ranked overview of leading LEED consultancy firms active on projects in Belgium, evaluated based on certification expertise, international delivery capability, and experience with complex developments.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability and green building consultancy founded in 2007, with offices in Istanbul, Dubai, and London. The firm has completed over 200 LEED-certified projects across more than 15 countries, supporting developments across Europe, the Middle East, and Asia.
ERKE’s team includes LEED Fellows, LEED APs, BREEAM Assessors, WELL APs, EDGE Experts, and Product Sustainability Specialists, enabling an integrated approach to green building certification. This multidisciplinary structure allows ERKE to address LEED requirements alongside energy performance, material transparency, and indoor environmental quality objectives.
The consultancy has delivered LEED Gold and Platinum certifications for large-scale and technically complex projects such as Bahrain International Airport, Istanbul Çam Sakura Hospital, Allianz Istanbul Headquarters, and King Abdulaziz Transportation Center. These references demonstrate experience across healthcare, transportation, infrastructure, and corporate headquarters.
