From transposition to implementation
On 13 May 2026, EU-funded initiatives will join the European Commission (DG ENER) in Brussels and online for the hybrid event “Supporting EPBD implementation: Practical solutions developed by EU-funded initiatives”. The event takes place at a critical moment, just ahead of the 29 May deadline for transposing the revised Energy Performance of Buildings Directive (EPBD), when attention across Member States is shifting from legislative adoption to practical implementation.
Across Europe, the EPBD is moving from policy ambition to operational reality. This transition raises a set of practical questions. How should governance structures be organised? How can building data be made usable across systems? What tools are needed to support decision-making, and how can investment frameworks align with implementation needs? The event is designed to address these questions by bringing together EU institutions, national authorities, EU-funded projects and practitioners working directly on delivery.
Building the implementation system
The programme is structured around three sessions that reflect different layers of implementation. The first session focuses on the broader implementation system, looking at how policy, market uptake, digitalisation and finance interact. Discussions will consider how these elements must work together if EPBD requirements are to translate into measurable results on the ground. In this context, building-stock data, Energy Performance Certificates and the Smart Readiness Indicator are presented not as isolated instruments, but as part of a wider system supporting renovation and improved building performance.
Tracking progress and
identifying gaps
The second session turns to monitoring and evaluation. As Member States begin to implement the Directive, the question becomes how progress can be tracked and assessed over time. Observatories,
indicators and data systems play a central role in this process. They help identify where implementation is progressing and where gaps remain, while also enabling comparison across national contexts. The session also explores how EU-funded initiatives and support structures can contribute to making implementation efforts more transparent and actionable.
From standards to operational tools
The third session focuses on the technical and operational dimension of implementation. Here, the emphasis shifts to the tools, methods and collaborative approaches that support delivery in practice. EU-funded projects present how they are working with methodologies, data structures and interoperability frameworks to support national authorities and market actors. The aim is to demonstrate how technical solutions can enable consistent and scalable implementation of EPBD requirements across different Member States.
Open building data and practical delivery
OpenBEP4EU contributes to this discussion by addressing the technical layer underlying building performance assessment. By translating the CEN/ISO 52000 family of EPB standards into open and testable calculation methods, the project works towards making Energy Performance Certificates and Smart Readiness Indicator results more transparent, comparable and usable across systems. This approach supports a more consistent basis for decision-making, which is particularly relevant when data are used to guide renovation strategies, public investment and policy evaluation.
The event builds on a first day, “Voices of Change: Success stories shaping Europe’s buildings”, which focuses on real-world experiences from renovation and decarbonisation projects across Europe. Together, the two days reflect a broader transition in the European building sector, from showcasing successful examples to establishing the systems and tools needed to replicate them at scale.
As implementation of the EPBD accelerates, the challenge is no longer to define what should be done, but to ensure that it can be delivered in a consistent and effective way across diverse national contexts. Events such as this provide a space to align approaches, share practical solutions and strengthen coordination between the actors involved.
