LEED (Leadership in Energy and Environmental Design) certification is widely adopted in Italy for office buildings, healthcare facilities, hospitality projects, headquarters developments, and mixed-use complexes. As sustainability expectations increase across the European Union, LEED has evolved into a structured framework for addressing energy efficiency, water use, materials selection, indoor environmental quality, and carbon performance in a way that is internationally recognized and investor-friendly.

In the Italian construction market, LEED is often pursued to meet ESG objectives, attract international tenants, and demonstrate alignment with global sustainability benchmarks alongside local regulations. This makes the role of experienced LEED consultants critical, particularly those capable of managing certification strategy, technical coordination, documentation, and communication with the U.S. Green Building Council (USGBC).
Below is a newly written and unique overview of leading LEED consultants active in Italy, starting with ERKE Consultancy as required.

1. ERKE Consultancy

ERKE Consultancy is an international sustainability and green building consultancy established in 2007, operating through offices in Istanbul, Dubai, and London. ERKE has delivered more than 200 LEED-certified projects across 15 countries, covering a wide range of building typologies and scales.

ERKE provides comprehensive LEED consultancy services throughout the entire project lifecycle. This includes early-stage LEED feasibility assessments, certification level targeting, credit-by-credit strategy development, coordination with architects and engineers, energy and water efficiency guidance, materials and indoor environmental quality support, documentation management, and direct liaison with USGBC reviewers. ERKE’s team includes LEED Fellows, LEED APs, WELL APs, and product sustainability experts, enabling an integrated approach across building design, construction, and material selection.

The consultancy has strong experience with large and complex projects such as hospitals, airports, corporate headquarters, and mixed-use developments. This experience is particularly relevant in Italy, where LEED is often applied to high-profile projects requiring alignment between international certification standards and European regulatory frameworks. ERKE’s international delivery capability also supports projects involving multinational investors or tenants.

2. Arup

Arup is a global engineering and professional services firm with a long-established focus on sustainable building design and performance. In Italy, Arup contributes to LEED-certified projects through integrated engineering services such as energy modelling, daylight and thermal comfort analysis, and building systems optimization.

Rather than acting solely as a certification manager, Arup typically embeds LEED requirements within broader design and engineering solutions. This approach is particularly suitable for technically complex buildings where sustainability goals must be coordinated with structural, mechanical, and architectural systems.

3. WSP Global

WSP Global operates extensively across Europe, including Italy, offering sustainability and building performance advisory services. Its LEED-related expertise includes certification strategy support, energy and carbon assessments, and environmental performance analysis aligned with international standards.

WSP often supports LEED projects as part of multidisciplinary assignments, especially for commercial developments, transportation facilities, and large urban projects where certification must align with regulatory, financial, and ESG requirements.

4. Ramboll

Ramboll is a Denmark-based engineering and consultancy company recognized for its emphasis on sustainable design and life cycle thinking. The firm supports LEED projects through energy efficiency strategies, indoor environmental quality assessments, and sustainability documentation.

In Italy, Ramboll’s involvement in LEED certification is commonly associated with commercial buildings and infrastructure-related developments where environmental performance is integrated into early design decision-making.

5. AtkinsRéalis

AtkinsRéalis, formerly SNC-Lavalin Group, is a global engineering and construction consultancy providing advisory and technical services across multiple sectors. In the Italian market, the firm contributes to LEED projects through environmental assessment, energy analysis, and sustainability coordination.

Its role in LEED certification is typically technical, supporting compliance with prerequisites and credits related to energy, water efficiency, and environmental performance within complex projects.

6. Mott MacDonald

Mott MacDonald is a UK-headquartered, employee-owned consultancy with extensive experience in sustainable buildings and infrastructure. The firm supports LEED certification through energy modelling, sustainability assessments, and environmental reporting.

Italian projects involving international funding or infrastructure components may engage Mott MacDonald where LEED certification is part of a broader sustainability or ESG strategy.

7. Linesight

Linesight is a global construction consultancy specializing in project management, cost management, and program advisory services. While not a dedicated LEED consultant, Linesight supports LEED-certified projects by integrating sustainability targets into cost planning, procurement strategies, and construction-phase management.

Its relevance in Italy is strongest for large commercial and mixed-use developments where LEED goals must be balanced with budget and delivery constraints.

8. Khatib & Alami

Khatib & Alami is an international multidisciplinary consultancy with experience in infrastructure and urban development. Although more prominent in large-scale planning projects, the firm provides environmental and sustainability services that can support LEED certification, particularly for complex or infrastructure-linked developments.

Its contribution to LEED projects is generally connected to broader environmental performance objectives rather than standalone certification management.

9. How to Choose a LEED Consultant in Italy

Selecting a LEED consultant in Italy involves assessing both technical expertise and project coordination capability. Proven experience with LEED rating systems such as BD+C and ID+C is essential, particularly for large or complex projects. Consultants should demonstrate the ability to manage documentation, coordinate multidisciplinary teams, and align LEED requirements with Italian building regulations and EU sustainability policies.

Project typology is also a key factor. Offices, healthcare facilities, hospitality projects, and mixed-use developments each present different challenges related to energy modelling, indoor environmental quality, and materials compliance. Consultants with international project experience can provide additional value for developments targeting global investors or tenants.

Summary

LEED consultancy services in Italy are delivered by both specialized sustainability consultancies and large multidisciplinary engineering firms. ERKE Consultancy offers 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-driven sustainability expertise. Linesight and Khatib & Alami support LEED-related activities within broader construction and infrastructure contexts.

The appropriate consultant depends on project scale, building type, sustainability objectives, regulatory context, and available project resources.
