LEED Certification

LEED (Leadership in Energy and Environmental Design) is one of the most widely recognised green building rating systems in the world. Developed by the U.S. Green Building Council (USGBC), it sets criteria for the design, construction, operation and maintenance of environmentally responsible buildings, and is used in more than 180 countries and territories.

What is LEED certification?

LEED is a points-based system: a project earns credits across several categories, and its total score determines the certification level achieved.

• Certified: 40-49 points.
• Silver: 50-59 points.
• Gold: 60-79 points.
• Platinum: 80 or more points.

It applies to many project types, including new construction, major renovations, commercial interiors, neighbourhood development and existing buildings in operation.

Evaluation categories

• Location and transportation: rewards accessible sites well connected to public transport.
• Sustainable sites: promotes ecosystem protection and responsible land use.
• Water efficiency: assesses strategies that reduce water consumption.
• Energy and atmosphere: favours renewable energy and lower greenhouse gas emissions.
• Materials and resources: prioritises recycled, regional and low-impact materials, including attention to embodied carbon.
• Indoor environmental quality: considers ventilation, daylight and air quality for occupant health.
• Innovation and regional priority: recognises novel strategies and locally relevant issues.

LEED v5: the latest version

In April 2025 the USGBC released LEED v5 for its main commercial rating systems (Building Design and Construction, Interior Design and Construction, and Operations and Maintenance). LEED v5 reorganises credits around three impact areas, with roughly half of the points tied to decarbonisation and the remainder split between quality of life and ecological conservation and restoration. Platinum projects face new requirements on energy efficiency, carbon emissions and renewable energy. The USGBC has moved to a five-year update cycle, and LEED v5 is expected to become the only version available for new commercial registrations from 1 July 2027.

Benefits of LEED certification

• Lower operating costs: certified buildings typically use less energy and water.
• Higher asset value: LEED buildings often enjoy stronger market reputation and demand.
• Occupant well-being: better indoor quality supports health and productivity.
• Access to incentives and green finance: some authorities and lenders reward certified projects.
• Verified commitment: independent certification evidences a genuine sustainability strategy.

How the certification process works

1. Project registration on the USGBC's LEED Online platform.
2. Documentation, often with the support of accredited professionals (LEED AP).
3. Review by Green Business Certification Inc. (GBCI), the body that administers certification.
4. Award of the certification level once requirements are met and the score is verified.
5. Ongoing monitoring, particularly for buildings in operation, to sustain performance.

LEED has been adopted worldwide across offices, hospitals, universities, retail and infrastructure. In markets such as Mexico, organisations including SUMe (Sustentabilidad para Mexico) have promoted its use, adapting strategies to local climate and regulatory conditions.

Why pursue LEED?

LEED is a practical tool for moving towards more sustainable, resilient and healthy buildings, aligning architecture and engineering with the principles of sustainable development without sacrificing functionality. It pairs naturally with broader corporate climate work, such as measuring the building's carbon footprint and pursuing energy efficiency.

At Manglai we help organisations measure the carbon footprint behind their buildings, operations and projects, and prepare their sustainability reporting. Discover how Manglai can help you.
