LEED® certification (Leadership in Energy and Environmental Design) is one of the most widely recognized green building rating systems worldwide. It aims to create high-performing, responsible built environments that prioritize occupant well-being.
Going beyond regulatory requirements, LEED® promotes the reduction of carbon emissions, efficient use of resources, and improved quality of life at every stage of a building’s lifecycle.
A comprehensive approach to performance
LEED® certification is based on independent third-party verification, ensuring that projects meet high environmental and human performance standards.
It is structured around seven key categories:
- Location and transportation
Promoting accessible, well-connected sites that reduce travel needs and environmental impact. - Sustainable site development
Minimizing the project’s footprint and protecting surrounding ecosystems. - Water efficiency
Optimizing potable water use and encouraging reuse strategies. - Energy and atmosphere
Improving energy performance and reducing greenhouse gas emissions. - Materials and resources
Prioritizing sustainable, responsible, and low-impact materials. - Indoor environmental quality
Providing healthy, comfortable spaces that support occupant well-being. - Innovation
Encouraging innovative strategies and exemplary performance.
A certification adaptable to all projects
LEED® applies to a wide range of building types and contexts, including:
- New construction
- Interior fit-outs
- Existing buildings (operations and maintenance)
- Core and shell projects
This flexibility makes it a valuable tool for both public and private projects, regardless of scale.
Achieving LEED® certification demonstrates a concrete commitment to sustainable development while optimizing long-term operating costs. It also helps enhance a building’s attractiveness and value, while meeting growing expectations for environmental performance.
