OpenBEP4EU at the Smart Readiness Indicator 4th Joint Event — advancing integrated building assessment
On 22 October 2025, the Smart Readiness Indicator (SRI) 4th Joint Event — organised by the European Commission and CINEA — highlighted the growing convergence between Energy Performance Certificates (EPCs), smart-readiness assessments and auditing frameworks across Europe. The session underscored a key message: to deliver transparent, comparable and actionable building performance data, EPCs and SRIs must evolve from isolated tools into an integrated, interoperable ecosystem.
OpenBEP4EU’s role in shaping integration
As part of this evolving landscape, OpenBEP4EU is developing the EU Kernel EPC Engine — an open-source software implementation based on the ISO 52000 family of standards. Our aim is to provide a reliable, transparent and harmonised EPC calculation method that can serve as a common foundation for both EPC and SRI implementation.
In doing so, the project addresses a key need identified at the event: consistent calculation logic underpinning both certification and smart-readiness assessments. Through our work, building owners, auditors, public authorities, and finance actors gain access to comparable building-performance data — a necessary precondition for renovation strategies, sustainable financing and compliance with EPBD requirements.
From Separate Schemes to a Coherent Framework
The event showed that EPCs, SRI assessments, national auditing systems and digital tools are increasingly overlapping. Participants from multiple Member States stressed the need for shared data models, common calculation logic and interoperable workflows — before relying on building performance data for renovation planning, policy enforcement or financing decisions.
This development matters because, as the EU implements the recast Energy Performance of Buildings Directive (EPBD), the quality and trustworthiness of EPCs and SRI data must meet high expectations across borders. Inconsistent methodologies or fragmented tools risk undermining comparability, transparency and ultimately the usability of building-performance data.
What the Event Revealed
Several presentations and workshops echoed familiar challenges and opportunities. Member States shared early experiences from national SRI test phases. Auditing-scheme developers introduced standardised procedures aligned with SRI. Meanwhile, auditors and software providers discussed the need for shared data exchange protocols and transparent calculation methods.
This “real-world pressure test” validates OpenBEP4EU’s core premise: harmonised, open-source tools are not a luxury — they are a necessity. They offer a path to consistent EPCs, compatible SRI data and comparable building-performance information across all of Europe.
