The publication was developed within EPBD.wise, a LIFE-funded project that supports the implementation of the revised EPBD by helping Member States (MS) strengthen key policy instruments, exchange knowledge and develop practical guidance. One of its priorities is improving Energy Performance Certificates (EPCs), which under the revised Directive are expected to play a broader role in supporting building renovation, minimum energy performance standards, financing decisions and policy monitoring.

The report, 'Development of Energy Performance Certificates: Policy Guideline Summary', provides an operational framework for modernising EPC systems across the EU. While recognising that MS are at different stages of implementation, it proposes a common approach based on four policy pillars: governance, the core EPC scheme, support functions and communication. The recommendations are based on a comparative assessment of EPC systems in Bulgaria, Greece, Hungary and Poland. The analysis identifies several recurring challenges, including fragmented databases, inconsistent quality assurance, limited practical value of EPC recommendations and low public awareness of the certificates.

To address these issues, the publication recommends improving database interoperability, harmonising calculation methodologies, strengthening the training and accreditation of EPC experts, introducing independent quality control procedures and developing communication strategies that increase understanding of EPCs among building owners, occupants and other stakeholders. It also highlights the importance of integrating EPC data into broader monitoring and evaluation frameworks to support the implementation of the revised EPBD.

The publication is intended primarily for policymakers and public authorities responsible for implementing the revised EPBD, but it also provides useful guidance for organisations involved in energy performance certification and building renovation across Europe.
