Green Residential Buildings Methodology Assessment Document

The 2023 update to NN Bank's Green Residential Buildings Methodology shifts from a nationally-defined top 15% approach based on EPC ratings to alignment with EU Taxonomy criteria. The document now explicitly references EU Taxonomy Delegated Regulation requirements and introduces Primary Energy Demand (PED) as an alternative metric for measuring building energy performance. Additionally, the standard for new buildings has been updated from BENG minus 20% to NZEB minus 10%, reflecting more current European sustainability standards.

• added Standards Alignment — EU Taxonomy Delegated Regulation (June 2021) technical screening criteria for sustainable buildings now explicitly referenced as the basis for Eligible Green Loans methodology.
• expanded Eligibility Criteria — Added Primary Energy Demand (PED) as an alternative metric to EPC rating A for demonstrating top 15% building performance within national or regional building stock.
• modified Climate Target — New building standard updated from BENG minus 20% requirements to NZEB minus 10% PED requirement, aligning with current EU energy standards.
• tightened Eligibility Criteria — Baseline for comparison now explicitly limited to buildings built before 31st December 2020 and requires distinction between residential and non-residential buildings in comparative analysis.
• clarified Eligibility Criteria — Document purpose refined to explicitly explain EU Taxonomy criteria implications on selection of Eligible Green Loans for both existing and newly constructed buildings.
