Social housing
biodiversity, construction carbon, estate performance
Social housing providers manage a vast estate, build and renovate continuously, and report to demanding supervisory bodies. IRICE provides the certified measurement tools for biodiversity and construction carbon across your projects — from programming through to estate monitoring.
Biodiversity and carbon challenges for social housing
Social housing providers sit at the intersection of several obligations that converge on measuring environmental performance:
SNBC and carbon trajectory
The National Low Carbon Strategy sets reduction targets for the building sector. Social utility agreements (CUS) now include quantified environmental commitments.
TFPB tax relief
New social housing benefits from property tax relief (TFPB). Environmental criteria strengthen eligibility and extend the relief period.
RE2020 and carbon thresholds
RE2020 thresholds tighten (2025, 2028, 2031). Actual site-stage carbon measurement replaces the default value and frees up headroom on the overall carbon balance.
ZAN and artificialisation
Zero Net Artificialisation requires measuring soil biodiversity before and after intervention. A baseline assessment becomes a prerequisite for every project.
Three tools for the estate lifecycle
Effinature NCO + Efficarbone
New-build biodiversity certification + construction carbon measurement. A dual criterion that can be embedded in technical specifications and tender rules.
Effinature EVO + Efficarbone
Biodiversity certification adapted to refurbishment + renovation site emissions measurement. The EVO framework accounts for the constraints of existing buildings.
BPS — Biodiversity Performance Score
Biodiversity score across 70+ criteria for the existing estate. Enables multi-year monitoring, intervention prioritisation and reporting to supervisory bodies.
Typical pathway: from pilot project to full roll-out
Adoption typically follows three stages:
Pilot project
A new-build programme or major refurbishment serves as a test. The housing provider includes Effinature certification and/or Efficarbone measurement in the tender documents. Results feed the lessons-learned process.
Process integration
Standard clauses are formalised and embedded in the housing provider's specification templates. The BPS is deployed across the existing estate to establish a baseline.
Full roll-out and reporting
All new contracts include the criteria. The housing provider has benchmark data across projects and indicators for the CUS, annual report and supervisory exchanges.
Frequently asked questions
Yes. The NCO 25.05 (New construction) and EVO 25.05 (Renovation) frameworks cover all dwelling types, including social housing. The BPS assesses biodiversity performance regardless of tenure or funding model.
Biodiversity certification is independent of HLM approvals (PLUS, PLAI, PLS). It can be required as a complement by the funder or the conceding authority. Several social housing providers already include biodiversity requirements in their environmental quality charters.
The BPS assessment starts at EUR 3,500 excl. VAT per project. This cost fits within the studies budget and can be covered by funding dedicated to environmental quality. The return on investment includes CSRD compliance and estate value enhancement.
