Biodiversity and sustainable real estate news
Cost control is becoming a key indicator of environmental performance. As the 2025 rent guidelines now link rental margins to measurable reductions in household expenses, Effinature is anticipating this development by preparing a new certification criterion focused on ecological performance and cost control. This evolution integrates biodiversity into the ongoing energy efficiency initiatives, directly linking it to residents' energy bills.
A regulatory evolution that is shaping the market
The notice relating to rents 2025, published last February, marks a turning point in housing policy: from now on, additional rent margins can only be granted to operations with superior environmental quality resulting in an effective reduction of the charges borne by tenants.
This approach reinforces a simple idea: environmental performance is only worthwhile if it translates into tangible benefits. Energy efficiency alone is no longer sufficient; it is also necessary to demonstrate the overall impact of the project on water usage, comfort, maintenance, and quality of life.
Effinature aligns itself with this requirement for proof
For several months, IRICE has been preparing a revision of the Effinature standards (version 25.05.1) incorporating a new criterion:
“Ecological performance and control of operating costs.”
This criterion aims to quantify, from the design phase, the potential savings generated by the project's ecological features:
- integrated stormwater management,
- local and sustainable vegetation,
- natural thermal comfort
- differentiated maintenance of outdoor spaces.
The objective is clear: to measure the real contribution of biodiversity to energy efficiency, in addition to energy performance.
An approach designed to engage in dialogue with the DREALs
Annex 4 of the 2025 rent notice defines three conditions for recognizing a certification in the calculation of rent margins:
- a certification issued by an ISO/IEC 17065 accredited body;
- proof of a reduction in expenses;
- an independent and traceable assessment.
Effinature already addresses these three points structurally. The new criterion will provide the DREAL (Regional Directorate for the Environment, Planning and Housing) with a quantifiable and auditable framework for linking biodiversity and real savings. It will pave the way for explicit administrative recognition, comparable to that granted to energy certifications.
Towards a measurable, useful and enforceable ecology
This development aligns with the Effinature philosophy: to make biodiversity a factor in economic balance, not an additional burden. Every ecological requirement—infiltration, shade, sustainable vegetation—becomes a lever for cost reduction and improved comfort.
By anticipating this development, IRICE demonstrates that biodiversity certification can contribute directly to public policies on housing and ecological transition.
Conclusion
The criterion “Ecological performance and cost control” will be presented in the 25.05.1 revision of the Effinature standards. It responds to the momentum generated by the 2025 rent guidelines and will allow project owners to demonstrate, with supporting evidence, that biodiversity reduces costs.
Effinature does not comment on the regulations: it anticipates them.
