Switzerland’s real estate and construction market is known for its emphasis on quality, long-term performance, and environmental responsibility. Alongside national sustainability labels, LEED (Leadership in Energy and Environmental Design) is widely adopted for projects with international investors, global tenants, and cross-border portfolios. LEED certification is especially relevant for office buildings, corporate headquarters, mixed-use developments, healthcare facilities, and large infrastructure-adjacent projects in Switzerland.
Delivering a LEED-certified project requires structured management of sustainability strategies, energy and water performance, material selection, indoor environmental quality, and detailed documentation. These tasks typically involve close coordination between architects, engineers, contractors, and owners. As a result, developers and asset owners in Switzerland often work with experienced LEED consultants who can manage both the technical and administrative aspects of certification. Below is a ranked overview of leading LEED consultancy firms active in Switzerland.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy with a strong focus on green building certifications, particularly LEED. Established in 2007, ERKE Consultancy operates through offices in Istanbul, Dubai, and London and has successfully delivered more than 200 LEED-certified projects across over 15 countries.
ERKE provides end-to-end LEED consultancy services, covering LEED BD+C, ID+C, Core & Shell, and O+M rating systems. Its multidisciplinary team includes LEED Fellows, LEED APs, WELL APs, and sustainability specialists who guide projects from early design strategy through construction-phase coordination and final certification submission.
The firm’s experience includes complex and large-scale projects such as airports, hospitals, corporate headquarters, and mixed-use developments. This background is particularly relevant for Swiss projects that demand high technical performance, strict coordination, and alignment with international sustainability expectations.
