The Buildings Performance Institute Europe (BPIE) report examines how Ireland is implementing the new requirements of the Energy Performance of Buildings Directive (EPBD) for energy performance certificates, known nationally as Building Energy Ratings (BERs), and whole-life carbon calculations. The new BER framework entered into force on 24 May 2026, simplifying the previous 15-class scale and incorporating the mandatory indicators established by the Directive.

BPIE highlights the quality control system, measures to improve the affordability of certificates and initial progress towards calculating life-cycle global warming potential. Ireland has developed a national methodology based on Level(s) and EN 15978, together with a database of carbon factors and a calculation tool.

The report also identifies areas for further improvement: legally defining worst-performing buildings, strengthening links between BERs and renovation passports, improving accessibility for households with limited digital access or literacy, and adapting certificate issuance requirements to cover major renovations and renewals of existing rental contracts.
