Switzerland is widely regarded as a leader in high-performance buildings, combining strict regulatory requirements with strong market demand for sustainability. While national systems such as Minergie are dominant, LEED (Leadership in Energy and Environmental Design) continues to play an important role for projects with international investors, global occupiers, and cross-border portfolios. LEED certification is particularly common for offices, headquarters, mixed-use developments, healthcare buildings, and complex infrastructure-related facilities.
Delivering a LEED-certified project in Switzerland requires careful alignment between design intent, technical performance, construction practices, and documentation. Energy and water modelling, materials assessment, indoor environmental quality strategies, and commissioning must all be managed in accordance with USGBC requirements. For this reason, Swiss developers and asset owners typically engage experienced LEED consultants with both international credentials and the ability to operate within Europe’s regulatory environment. The following firms are among the most relevant LEED consultants active in Switzerland.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy with extensive experience in LEED certification for large, technically demanding projects. Founded 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 comprehensive LEED consultancy services across 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 concept design 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 demand high technical accuracy, complex stakeholder coordination, and alignment with international sustainability benchmarks.

2. Arup
Arup has a long-standing presence in Switzerland and is widely recognised for its integrated engineering and sustainability expertise. Arup supports LEED certification as part of broader building performance, energy, and environmental design services.
In Switzerland, Arup’s LEED work is often linked to advanced energy simulations, façade optimisation, and whole-building performance strategies. The firm is typically engaged on 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. WSP supports LEED certification for commercial, institutional, and mixed-use developments.
Typical services include LEED strategy development, credit feasibility assessments, energy and water modelling, and management of certification documentation. WSP is often selected for 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 multiple countries, including Switzerland. Ramboll integrates LEED requirements into its broader sustainable building and engineering services.
The firm is particularly suited to projects that seek to balance 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 often focuses on sustainability strategy, performance assessment, and integration of LEED requirements into complex engineering-led projects 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 developments.
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 overview examined leading LEED consultants active in Switzerland, ranging from specialist sustainability consultancies to large multidisciplinary engineering firms. ERKE Consultancy is positioned as a consultancy with dedicated LEED expertise and extensive international experience on 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.
