Effinergie

Collectif Effinergie is a French association founded in 2006 and recognised as serving the public interest. It brings together a diverse network of members and partners to promote buildings that use less energy and have lower environmental and carbon impacts. The association supports the design and wider adoption of sustainable construction and renovation practices, working with professionals and local authorities across France.

Effinergie develops voluntary labels that help project owners highlight high-performing new buildings and renovations, while encouraging innovation and anticipating regulatory developments. Its Effinergie RE2020, Effinergie BBC, Effinergie Rénovation and Effinergie Patrimoine labels address different building and renovation contexts. The association also runs the Observatoire BBC, which gathers project feedback, analysis and studies to share practical lessons and showcase professional expertise.

To help the sector build knowledge and skills, Effinergie provides technical resources, guides, research and training accreditation for educational institutions and training organisations. Its expertise includes staged BBC renovations, building performance, air permeability, energy and carbon considerations at neighbourhood scale, and support for public policies promoting low-energy buildings.
