1. A shift in the financial paradigm

• The secondary private equity market is now worth over $160 billion - and growing fast.
• It becomes a strategic tool for investors, not a niche or adjustment market.
• The quality of ESG underlyings has become an entry requirement for Article 8 or 9 funds.
• A real estate asset that does not prove its ecological performance is out of the running.

2. The limits of declarative labels and uncertified approaches

• HQE, BREEAM or in-house labels are sometimes perceived as sufficient.
• But for long-term funds, what counts is the independence and enforceability of the assessment: A certified biodiversity score (Effinature, IRICE) A structured thermal and fluid audit (ARKEMEP) A controlled environmental compliance path (ARKENOR)
• A certified biodiversity score (Effinature, IRICE)
• A structured thermal and fluid audit (ARKEMEP)
• A controlled environmental compliance trajectory (ARKENOR)

3. What evergreen funds are now looking for

• Technical predictability: no uncertainties about energy performance, water management or acoustics.
• Ecological readability: not just a story, but a measuring grid.
• Auditable compliance: ability to meet the requirements of internal audits, SFDR labels, green taxonomy.

4. The ARKORIS response: combining engineering, project management and certification

ARKEMEP: thermal, acoustic and fluid structures - without overpromising

ARKENOR: environmental consulting, ecology, HQE / BDM certifications

IRICE: independent biodiversity certification (Effinature, BPS)

Together, these building blocks form a credible foundation for tomorrow's ESG real estate assets.

Conclusion

In a structured secondary market, ESG investments can no longer be sold without proof. ARKORIS installs this proof at the root of the project, to prevent it from being disqualified ten years later.
