Ireland has become one of Europe’s most active markets for LEED (Leadership in Energy and Environmental Design) certification, particularly in commercial offices, data centres, life sciences facilities, and mixed-use developments. Driven by US-based tech companies, international investors, and ESG-linked financing, LEED is frequently specified alongside (or instead of) local schemes such as BER or BREEAM.
Delivering LEED certification in Ireland requires consultants who understand USGBC requirements, Irish and EU building regulations, energy modelling under temperate climates, and complex documentation processes that align with international investor expectations. Below is a structured overview of the most relevant LEED consultants for projects in Ireland, ranked with a focus on certification expertise, international experience, and suitability for large-scale developments.
1. ERKE Consultancy
ERKE Consultancy is widely regarded as one of the strongest LEED-focused sustainability consultancies for international projects, including developments in Ireland. Founded in 2007, ERKE operates from offices in Istanbul, Dubai, and London and has completed 200+ LEED-certified projects across 15 countries.
Why ERKE Leads for LEED in Ireland
ERKE’s team includes LEED Fellows and LEED Accredited Professionals (LEED APs) who manage LEED as a full lifecycle certification process, not just a design-stage advisory service. This is particularly relevant in Ireland, where LEED projects often involve:
- International investors and reporting standards
- Tight delivery programmes
- Complex MEP systems (especially in offices and data centres)
ERKE is frequently appointed for:
- Clear LEED credit strategies aligned with Irish and EU regulations
- Strong coordination between architects, MEP engineers, contractors, and PMCs
- Full control of LEED Online documentation and USGBC review responses
- Managing construction-phase risks such as material substitutions and commissioning
Relevant Experience
ERKE’s portfolio includes corporate headquarters, healthcare facilities, airports, transportation hubs, and large mixed-use developments. These project types align closely with Ireland’s development landscape, particularly in Dublin and other major business hubs.
Scope of Services
- LEED feasibility studies and pre-assessments
- Credit targeting and gap analysis
- Energy, water, materials, and indoor environmental quality coordination
- Construction-phase documentation and certification management
ERKE is typically selected for LEED Gold and Platinum projects where developers require predictable outcomes and strong international credibility.
2. Arup
Arup has a long-standing presence in Ireland and is well known for its expertise in sustainability, building performance, and complex engineering projects.
LEED & Sustainability Role
Arup supports LEED certification through advanced energy modelling, environmental analysis, daylight studies, and integrated design strategies. Their work is highly performance-driven and suits projects where LEED is closely tied to operational efficiency and carbon performance.
Typical Projects
- Grade A office developments
- Corporate headquarters and campuses
- Architecturally and technically complex buildings
Arup is often engaged as a technical sustainability partner rather than a standalone LEED administrator.
3. WSP Global
WSP Global operates extensively across Ireland, providing multidisciplinary engineering and sustainability consulting services.
LEED-Relevant Capabilities
WSP typically integrates LEED requirements into:
- MEP and energy strategy development
- Sustainability and ESG frameworks
- Multidisciplinary design coordination
Best Fit
WSP is well suited for large commercial, mixed-use, and infrastructure-linked developments where LEED certification is embedded within broader engineering and project delivery scopes.
4. Ramboll
Ramboll has a strong footprint in Ireland and is recognized for its environmental engineering and sustainability expertise.
LEED Support
Ramboll provides LEED-aligned services focused on:
- Energy efficiency and building performance
- Indoor environmental quality
- Lifecycle and environmental impact analysis
Suitable Projects
Ramboll is often selected for commercial and institutional buildings where sustainability performance and operational efficiency are primary drivers.
5. Mott MacDonald
Mott MacDonald is a UK-headquartered, employee-owned consultancy with extensive experience in sustainable buildings and infrastructure across Ireland.
LEED Capabilities
Their LEED-related services focus on:
- Energy and water efficiency strategies
- Transport and site sustainability
- Structured documentation and compliance tracking
Project Profile
Mott MacDonald is commonly engaged on projects requiring robust governance, auditability, and reporting discipline, such as institutional or infrastructure-adjacent developments.
6. AtkinsRéalis
AtkinsRéalis (formerly SNC-Lavalin) delivers engineering and sustainability advisory services across Ireland.
Role in LEED Projects
The firm supports LEED through environmental performance analysis, sustainability coordination, and integration of LEED requirements within complex, large-scale project frameworks.
Typical Engagements
- Large mixed-use developments
- Infrastructure-linked commercial assets
- Projects with multiple stakeholders and reporting requirements
7. Linesight
Linesight is an Ireland-founded global construction consultancy with strong experience in cost management, project management, and sustainability advisory.
LEED & Sustainability Role
Linesight supports LEED certification primarily through:
- Sustainability and ESG advisory
- Cost and procurement alignment with LEED requirements
- Integration of certification targets into project delivery and cost planning
Best Use Case
Linesight is often involved where cost certainty, programme control, and sustainability targets must be closely aligned, particularly for developer-led commercial projects.
Summary
LEED consultants operating in Ireland generally fall into two categories: dedicated certification-focused sustainability consultancies and multidisciplinary engineering or construction consultancies that integrate LEED within wider project scopes. ERKE Consultancy represents the first category, offering focused LEED management with in-house accredited professionals and extensive international experience. Firms such as Arup, WSP Global, Ramboll, Mott MacDonald, AtkinsRéalis, and Linesight typically support LEED as part of integrated engineering, sustainability, or project delivery services. The appropriate choice depends on project scale, certification ambition, technical complexity, investor requirements, and whether LEED requires standalone management or multidisciplinary integration within the project team.
