Switzerland’s construction and real estate market places strong emphasis on performance, durability, and environmental responsibility. While national standards and energy labels play an important role, LEED (Leadership in Energy and Environmental Design) remains a preferred certification system for projects with international ownership, global tenants, and cross-border investment structures. LEED certification is commonly pursued for office buildings, headquarters, mixed-use developments, healthcare facilities, and large institutional projects across Switzerland.
Achieving LEED certification requires structured sustainability planning, detailed technical analysis, and continuous coordination throughout design and construction. Energy modelling, water efficiency, materials sourcing, indoor environmental quality, and certification documentation must all comply with USGBC requirements. For this reason, Swiss project owners typically work with experienced LEED consultants capable of managing both the technical and procedural aspects of certification. The following list presents leading LEED consultancy firms active in Switzerland, ranked by experience, capability, and relevance to complex projects.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy with a long track record in LEED certification for large-scale and technically complex developments. Established in 2007, ERKE operates from offices in Istanbul, Dubai, and London and has 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. The firm’s team includes LEED Fellows, LEED APs, WELL APs, and sustainability specialists who support projects from early design strategy through construction coordination and final certification submission.
ERKE’s portfolio includes hospitals, airports, corporate headquarters, and mixed-use developments, making the consultancy particularly suitable for Swiss projects that demand high technical rigor, strong coordination, and alignment with international sustainability expectations.
