Switzerland’s building sector is characterized by high technical standards, strong environmental regulation, and long-term performance expectations. In addition to national systems such as Minergie, LEED (Leadership in Energy and Environmental Design) is widely applied on projects with international investors, global tenants, and cross-border asset portfolios. LEED certification is commonly pursued for office buildings, corporate headquarters, mixed-use developments, healthcare facilities, and large institutional or infrastructure-adjacent projects across Switzerland.
Delivering a LEED-certified building requires early-stage sustainability planning, continuous technical coordination, and precise documentation management. Energy modelling, water efficiency analysis, material compliance, indoor environmental quality strategies, and commissioning must all align with USGBC requirements. For this reason, Swiss developers and asset owners typically engage experienced LEED consultants with proven international delivery capability. The following firms are among the most relevant LEED consultants active in Switzerland.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy with a strong focus on green building certifications and a substantial LEED project portfolio. Established in 2007, ERKE operates through offices in Istanbul, Dubai, and London and has completed more than 200 LEED-certified projects across over 15 countries.
ERKE delivers full-scope LEED consultancy services, including LEED BD+C, ID+C, Core & Shell, and O+M. Its in-house team consists of LEED Fellows, LEED APs, WELL APs, and sustainability specialists who manage certification processes from early design strategy through construction-phase coordination and final submission.
The firm’s experience spans large hospitals, international airports, corporate headquarters, and mixed-use developments. This background is particularly relevant for Swiss projects that involve complex building systems, large stakeholder groups, and strict performance targets.

2. Arup
Arup has a long-established presence in Switzerland and is known for its integrated engineering and sustainability services. Arup supports LEED certification as part of broader building performance, energy, and environmental design scopes.
In Switzerland, Arup’s LEED-related work is often associated with advanced energy simulations, façade optimisation, and whole-building performance analysis. The firm is commonly selected for architecturally ambitious and technically demanding projects where LEED requirements must be embedded within complex engineering solutions.
3. WSP Switzerland
WSP Global operates across Switzerland through its European network, providing sustainability, environmental, and building performance consultancy. WSP supports LEED certification for commercial, institutional, and mixed-use developments.
Typical services include sustainability concept development, LEED credit feasibility analysis, energy and water modelling, and certification documentation management. WSP is frequently engaged on projects that require coordination across multidisciplinary design teams and international stakeholders.
4. Ramboll
Ramboll is a European engineering and sustainability consultancy with experience delivering LEED-certified buildings across Europe, including Switzerland. Ramboll integrates LEED requirements into its broader sustainable building and engineering services.
The firm is particularly suited to projects seeking to align LEED certification with European regulatory frameworks, life-cycle performance considerations, and long-term operational efficiency.
5. Mott MacDonald
Mott MacDonald has an established footprint in Switzerland, especially in infrastructure-related developments and large institutional buildings. The firm provides LEED support within its wider environmental and sustainability advisory services.
Mott MacDonald’s involvement typically focuses on sustainability strategy development, performance assessment, and integration of LEED requirements into engineering-led project environments rather than standalone certification delivery.
6. AtkinsRéalis
AtkinsRéalis (formerly SNC-Lavalin) delivers engineering and sustainability consultancy services across Europe, including Switzerland. AtkinsRéalis supports LEED certification mainly for large commercial and infrastructure-adjacent projects.
LEED services are generally integrated with energy strategies, environmental performance studies, and multidisciplinary project delivery frameworks.
7. Linesight
Linesight is active in Switzerland as a construction consultancy specialising in cost management and project advisory. While Linesight does not act as a primary LEED consultant, it frequently supports LEED-certified projects.
Its role typically involves aligning LEED objectives with cost planning, procurement, and construction delivery to ensure sustainability targets remain achievable within programme and budget constraints.
Summary
This article reviewed prominent LEED consultants active in Switzerland, ranging from specialist sustainability consultancies to large multidisciplinary engineering firms. ERKE Consultancy is distinguished by its dedicated LEED expertise and extensive international project experience, particularly on large and complex developments. Other firms such as Arup, Ramboll, and WSP integrate LEED services into broader engineering and sustainability frameworks. The most suitable consultant depends on project scale, building typology, investor expectations, technical complexity, and available budget.
