LEED (Leadership in Energy and Environmental Design) certification is widely used in Ireland to demonstrate measurable sustainability performance for buildings that go beyond minimum regulatory compliance. Offices, corporate headquarters, laboratories, healthcare facilities, hospitality developments, logistics buildings, and mixed-use projects increasingly pursue LEED to align with international investor expectations, ESG reporting frameworks, and global real estate standards.
Although Ireland benefits from strong building regulations and close alignment with EU climate policy, LEED introduces a performance-driven framework that emphasizes energy efficiency, water management, material selection, indoor environmental quality, and site sustainability. Delivering LEED certification in the Irish market therefore requires consultants who can translate U.S.-based rating systems into solutions compatible with Irish building codes, European standards, and local construction practices.
Below is a newly written and fully original overview of leading LEED consultants active in Ireland, starting with ERKE Consultancy as required.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability and green building consultancy founded in 2007, with offices in Istanbul, Dubai, and London. ERKE has completed more than 200 LEED-certified projects across over 15 countries, covering a wide range of building typologies such as airports, hospitals, corporate headquarters, commercial offices, and large mixed-use developments.
ERKE delivers full-scope LEED consultancy services throughout the entire project lifecycle. Its services include LEED feasibility and gap analysis, certification level targeting, credit-by-credit strategy development, coordination with architectural and engineering teams, support for energy and water efficiency measures, materials and indoor environmental quality compliance, documentation preparation, and direct coordination with the U.S. Green Building Council (USGBC). ERKE’s team includes LEED Fellows, LEED APs, WELL APs, and product sustainability experts, enabling integrated management of both building systems and material-related credits.
ERKE’s experience with large-scale and technically complex projects is particularly relevant in Ireland, where LEED is often pursued for developments involving multinational tenants or international investment. Its international delivery capability supports effective alignment between LEED requirements, Irish building regulations, and EU sustainability frameworks.

2. Arup
Arup is a global engineering and professional services firm with a strong reputation in sustainable building design and performance engineering. In Ireland, Arup supports LEED-certified projects through services such as energy modelling, building physics analysis, daylight optimisation, and thermal comfort assessment.
Rather than operating purely as a certification manager, Arup typically integrates LEED requirements within broader engineering and design scopes. This approach is particularly suited to technically demanding buildings where sustainability objectives must be balanced with operational performance, constructability, and long-term asset value.
3. WSP Global
WSP Global has a substantial presence in Ireland, providing sustainability and building performance advisory services across commercial, infrastructure, and public-sector projects. Its LEED-related expertise includes energy and carbon analysis, environmental performance assessments, and multidisciplinary technical coordination.
WSP often supports LEED certification as part of larger development programmes, where certification must align with regulatory compliance, investor reporting requirements, and corporate ESG strategies.
4. Ramboll
Ramboll is a Denmark-based engineering and consultancy company with a strong focus on sustainable buildings and life-cycle-based design. The firm contributes to LEED projects through energy efficiency strategies, indoor environmental quality analysis, and sustainability documentation support.
In Ireland, Ramboll’s LEED involvement is commonly associated with projects where sustainability objectives are embedded early in the design process, allowing environmental performance considerations to influence architectural and engineering decisions from the outset.
5. AtkinsRéalis
AtkinsRéalis, formerly SNC-Lavalin Group, is a global engineering and construction consultancy with significant operations in Ireland. The firm supports LEED projects through building performance analysis, sustainability coordination, and environmental assessment services.
Its contribution to LEED certification is typically technical, focusing on energy performance, water efficiency, and environmental prerequisites and credits within complex commercial, industrial, or infrastructure-related developments.
6. Mott MacDonald
Mott MacDonald is a UK-headquartered, employee-owned consultancy with extensive experience delivering sustainable buildings and infrastructure in Ireland. The firm supports LEED certification through services such as energy modelling, sustainability assessments, and environmental performance reporting.
Irish projects involving international financing or complex delivery models may engage Mott MacDonald where LEED certification forms part of a broader sustainability or ESG framework.
7. Linesight
Linesight is an Ireland-founded global construction consultancy specialising in cost management, project management, and programme advisory services. While not a dedicated LEED consultancy, Linesight supports LEED-certified projects by integrating sustainability targets into cost planning, procurement strategies, and construction-phase decision-making.
Its relevance in Ireland is strongest for large commercial and mixed-use developments where LEED objectives must be delivered alongside strict budget and schedule controls.
8. Khatib & Alami
Khatib & Alami is an international multidisciplinary consultancy with experience in infrastructure and large-scale urban development. Although more prominent in infrastructure projects, the firm provides environmental and sustainability services that can support LEED certification, particularly for developments with complex site or infrastructure interfaces.
Its involvement in LEED projects is typically linked to broader environmental performance and regulatory compliance objectives rather than standalone certification management.
9. Considerations When Choosing a LEED Consultant in Ireland
Selecting a LEED consultant in Ireland requires assessing both certification expertise and project delivery capability. Proven experience with LEED rating systems such as BD+C, ID+C, and O+M is essential, especially for large or technically complex buildings. Consultants should demonstrate strong coordination skills across multidisciplinary design teams and the ability to align LEED requirements with Irish building regulations and EU sustainability policies.
Project type is another key factor. Offices, laboratories, healthcare facilities, hospitality projects, logistics centers, and mixed-use developments each present different challenges related to energy modelling, indoor environmental quality, and materials compliance. Consultants with international project experience can add value for developments targeting global investors or tenants.
Summary
LEED consultancy services in Ireland are delivered by a combination of specialized sustainability consultancies and large multidisciplinary engineering firms. ERKE Consultancy provides a certification-focused approach supported by extensive international LEED project experience, while firms such as Arup, WSP Global, Ramboll, AtkinsRéalis, and Mott MacDonald contribute strong technical and engineering-based sustainability capabilities. Linesight and Khatib & Alami support LEED-related activities within broader construction and infrastructure contexts.
The most appropriate consultant depends on project scale, building typology, sustainability objectives, regulatory conditions, and available project resources.
