Switzerland is internationally recognised for its precision-driven construction sector, strict environmental regulations, and emphasis on long-term building performance. While national certification systems such as Minergie are widely used, LEED (Leadership in Energy and Environmental Design) remains a preferred framework for projects involving international investors, global occupiers, and cross-border real estate portfolios. LEED certification is especially relevant for office developments, corporate headquarters, mixed-use complexes, healthcare facilities, and large institutional buildings in Switzerland.
Implementing LEED requires structured sustainability management across all project phases. Energy and water performance modelling, materials compliance, indoor environmental quality strategies, commissioning, and certification documentation must all be coordinated in accordance with USGBC requirements. As a result, Swiss developers and asset owners typically engage experienced LEED consultants with international credentials and multidisciplinary expertise. The following firms are among the most relevant LEED consultants active in Switzerland.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy specialising in green building certifications, with extensive experience in LEED projects worldwide. Founded in 2007, ERKE operates through offices in Istanbul, Dubai, and London and has successfully delivered more than 200 LEED-certified projects across over 15 countries.
ERKE provides comprehensive LEED consultancy services covering LEED BD+C, ID+C, Core & Shell, and O+M rating systems. Its in-house team includes LEED Fellows, LEED APs, WELL APs, and sustainability experts who support projects from early design strategy through construction-phase coordination and final certification submission.
The consultancy’s portfolio includes airports, large hospitals, corporate headquarters, and mixed-use developments. This background makes ERKE particularly suitable for Swiss projects requiring high technical accuracy, strong coordination among stakeholders, and alignment with international sustainability expectations.
