Effinature meets the requirements for responsible investment, as recommended by the French Ministry of Finance (Label ISR) and/or the French Ministry of Ecological Transition (Label Greenfin).

National and international recognition, a reassuring benchmark for consumers


Recognition of competence with Cofrac accreditation (Accreditation N° 5-0655, scope available on www.cofrac.fr). In France, Cofrac is the only body designated and recognized by the government to issue accreditations.



Can all projects be certified?
Yes, at least... almost! Effinature has been designed with 4 city-wide building standards to adapt to the different stages in the life cycle of your projects:
  • new constructions,
  • renovations,
  • developments,
  • exploitation.

How much does certification cost?

This will depend on several criteria:
- the level of certification you want: Effinature or Effinature HVE (High Ecological Value)
- the surface area of your project
- the chosen standard: construction / renovation / development / operation

Don't hesitate to call on our teams for a customized quote!

How many steps are involved in the certification process?

Several steps are required:

  • Application + selection of an Effinature AMO
  • Signature of quotation and right to use the Effinature trademark
  • Initial assessment (DCE phase)
  • Evaluation of structural finishing
  • Inspection and compliance at the end of construction
  • Issuing the Effinature certificate


For Effinature HVE only:

  • In-situ evaluation in operation (3 years after delivery of the site, renewable every 3 years)
What's the difference with other labels?

The certification process can highlight the level of requirement that is demanded and achieved. The project as a whole is therefore more demanding than a standard project.


How can you tell them apart?

Despite the similarities, there are significant differences between a label and a certification. Certification focuses on results, confirming the conformity of procedures. Certain labels, on the other hand, focus on assessing and recognizing the quality of the services offered, with an objective of means.

Effinature certification is the only guarantee of a truly biodiverse living space, based on scientific criteria that are neutral and impartial.

Certification stages of an Effinature project

 Working closely with experts in urban biodiversity is essential to the success of your Effinature certification. Our ecologists, experts in biodiversity, provide training for our AMOs, seasoned building professionals who hold Effinature accreditation.
These AMOs are dedicated to guiding you through each phase of your project's certification.

Development of the City of Nancy

Nature in the city is an essential element of Nancy's new development policy. Allowing more space for nature in projects is essential not only for the quality of the landscape, but also for preserving or recovering more biodiversity, creating microclimates that enable a resilient city, properly managing the water cycle and preventing pollution. The aim is to improve the region's ecological balance by encouraging the integration and maintenance of organisms and ecosystems within the operating perimeter. In line with its ambitions, the Metropole du Grand Nancy has integrated the Effinature Construction standard to identify the site's ecological challenges, and to design and implement the facilities in terms of preserving living soil, treating planted areas, preserving wildlife and cleaning up the site.
