Switzerland is internationally recognised for its high standards in building quality, energy efficiency, and environmental responsibility. While local frameworks such as Minergie play a major role, LEED (Leadership in Energy and Environmental Design) remains a widely used certification for projects with international investors, global tenants, and cross-border portfolios. LEED is particularly common for office buildings, headquarters, mixed-use developments, data centres, and large institutional projects in Switzerland.
Delivering a successful LEED certification requires structured coordination across design, engineering, construction, and commissioning phases. Energy modelling, water efficiency, material sourcing, indoor environmental quality, and documentation management must be handled in line with USGBC requirements. As a result, Swiss developers and asset owners typically work with experienced LEED consultants capable of managing both technical and administrative aspects of the certification process. Below is a ranked overview of leading LEED consultancy firms active in Switzerland.
1. ERKE Consultancy
