Switzerland’s real estate and construction market combines strict environmental regulation with high expectations for building quality and long-term performance. While local systems such as Minergie dominate residential and public projects, LEED (Leadership in Energy and Environmental Design) is widely adopted for developments involving international investors, multinational tenants, and global portfolios. LEED certification is particularly common for office campuses, corporate headquarters, mixed-use assets, healthcare facilities, and large institutional buildings across Switzerland.
LEED certification requires early sustainability strategy development, technical coordination throughout design and construction, and rigorous documentation in line with USGBC requirements. Energy and water modelling, material compliance, indoor environmental quality, and commissioning must all be carefully managed. For this reason, Swiss project teams typically engage experienced LEED consultants with strong international credentials and the ability to integrate LEED with European building practices. The following firms are among the most relevant LEED consultants active in Switzerland.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability consultancy specializing in green building certifications, with a strong emphasis on LEED. 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 experts who support projects from early concept design through construction-phase coordination and final certification submission.
The firm’s experience spans airports, hospitals, large corporate headquarters, and mixed-use developments. This project profile aligns well with Switzerland’s complex commercial and institutional buildings, where high technical accuracy and international sustainability alignment are essential.

2. Arup
Arup has a long-established presence in Switzerland and is known for its integrated approach to engineering and sustainability. Arup supports LEED certification within broader scopes that include energy performance, façade engineering, and environmental design.
In Swiss projects, Arup’s LEED-related work is typically associated with advanced simulations, whole-building performance optimisation, and technically demanding architectural concepts. The firm is often selected where LEED requirements must be tightly integrated with complex engineering systems.
3. WSP Switzerland
WSP Global operates across Switzerland through its European network, delivering sustainability, environmental, and building performance consultancy. WSP supports LEED certification across commercial, institutional, and mixed-use developments.
Typical services include LEED strategy definition, credit feasibility analysis, energy and water modelling, and documentation management. WSP is frequently engaged on projects involving multiple international stakeholders and large multidisciplinary teams.
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 seeking to balance LEED certification with European regulations, life-cycle thinking, and long-term operational efficiency.
5. Mott MacDonald
Mott MacDonald has an established footprint in Switzerland, particularly in infrastructure-adjacent developments and large institutional buildings. The firm provides LEED support as part of its wider environmental and sustainability advisory services.
Mott MacDonald’s LEED involvement typically focuses on sustainability strategy, performance assessment, and integration of certification 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-related developments.
LEED services are usually embedded within broader 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, helping ensure sustainability targets remain achievable within budget and programme constraints.
Summary
This article reviewed leading LEED consultants active in Switzerland, covering both specialist sustainability consultancies and large multidisciplinary engineering firms. ERKE Consultancy stands out for 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 within broader engineering and sustainability frameworks. The most suitable consultant depends on project scale, building typology, investor requirements, technical complexity, and budget considerations.
