Switzerland’s built environment is shaped by strict energy regulations, advanced engineering standards, and strong demand for long-term asset performance. Alongside national frameworks such as Minergie, LEED (Leadership in Energy and Environmental Design) is widely adopted for developments backed by international investors, multinational occupiers, and global real estate portfolios. LEED certification is especially common for office buildings, corporate headquarters, mixed-use developments, healthcare facilities, and large institutional projects across Switzerland.
Successfully delivering LEED certification requires early-stage sustainability planning, continuous technical coordination, and precise documentation management. Energy modelling, water efficiency strategies, material sourcing, indoor environmental quality, and commissioning must all comply with USGBC requirements. As a result, Swiss developers and owners typically engage experienced LEED consultants with strong international credentials and multidisciplinary capability. The firms below 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 extensive LEED experience. Established in 2007, ERKE operates through offices in Istanbul, Dubai, and London and has delivered more than 200 LEED-certified projects across over 15 countries.
ERKE provides full-scope 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 specialists who support projects from early design strategy through construction coordination and final certification submission.
The firm’s portfolio includes airports, hospitals, large corporate headquarters, and mixed-use developments. This experience is particularly relevant for Swiss projects that involve complex building systems, high-performance envelopes, and international stakeholder coordination.

2. Arup
Arup has a long-established presence in Switzerland and is widely recognised 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 involvement is often associated with advanced energy simulations, façade optimisation, and whole-building performance analysis. The firm is typically selected for architecturally ambitious and technically complex projects where LEED requirements must be embedded within innovative engineering solutions.
3. WSP Switzerland
WSP Global operates across Switzerland through its European network, delivering sustainability, environmental, and building performance consultancy services. WSP supports LEED certification for commercial, institutional, and mixed-use developments.
Typical services include sustainability strategy development, LEED credit feasibility analysis, energy and water modelling, and documentation management. WSP is often engaged on projects requiring coordination across large multidisciplinary teams and international stakeholders.
4. Ramboll
Ramboll is a European engineering and sustainability consultancy with experience delivering LEED-certified projects across Europe, including Switzerland. Ramboll integrates LEED requirements into its broader sustainable building design and engineering services.
The firm is particularly suitable for projects aiming to align LEED certification with European regulations, life-cycle performance objectives, 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, 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 embedded within 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 examined leading 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 for large and complex developments. Other firms such as Arup, Ramboll, and WSP integrate LEED services within broader engineering and sustainability frameworks. The most appropriate consultant depends on project scale, building typology, investor requirements, technical complexity, and available budget.
