iEPB shares its solutions for interoperable building data and quality assurance at the Concerted Action EPBD meeting in Vienna
The European iEPB project participated in the 7th Plenary Meeting of the Concerted Action EPBD (CA-EPBD), held on 13–14 October 2026 in Vienna, Austria. The event provided an opportunity to share how iEPB’s Common Data Model and web application can support the implementation of the recast Energy Performance of Buildings Directive (EPBD), particularly in relation to building data interoperability, National Building Renovation Plans and the quality of building energy performance assessments.
The Concerted Action EPBD brings together representatives from EU Member States and Norway to exchange experiences, knowledge and good practices supporting the transposition and implementation of the Directive. Its plenary meetings are closed sessions, limited to the national experts responsible for implementing the EPBD and to representatives of the European Commission.
Eva Lucas Segarra, iEPB Project Coordinator from the Valencia Institute of Building (IVE), was invited to contribute to two technical sessions addressing key challenges in EPBD implementation.
Supporting National Building Renovation Plans through interoperable building data
On 13 October, iEPB contributed to the session Monitoring NBRP Implementation, coordinated by Susanne Geissler (SERA) and Naghmeh Altmann-Mavaddat (Austrian Energy Agency)
The presentation focused on the iEPB Common Data Model and web application, developed to facilitate the collection, exchange and reuse of building information across different assessment instruments, including Energy Performance Certificates (EPCs) and Smart Readiness Indicator (SRI) assessments. The model is also designed to accommodate Renovation Passports and other building assessments in future extensions.
Through practical examples of the iEPB web application, the presentation demonstrated how shared building data, connections with existing databases and integrated visualisation of assessment results can support information management at both individual-building and aggregated levels.
These capabilities are particularly relevant to the development of national databases for the energy performance of buildings under Article 22 of the EPBD, as well as to the monitoring of National Building Renovation Plans. By promoting structured, machine-readable and reusable information, iEPB offers an approach that could help Member States improve the availability and consistency of building performance data.
Improving quality across the EPC-to-Renovation Passport workflow
On 14 October, iEPB also contributed to the session EPC and RP Quality Control, coordinated by Rui Fragoso and João Cleto (ADENE, Portugal).
The presentation explored how quality assurance can be integrated throughout the building assessment and renovation planning process, rather than relying exclusively on checks performed once an assessment has been completed.
In this context, iEPB contributes to improving data quality from the initial stages of data collection, facilitating the reuse of reliable building information across different assessments. Its Common Data Model helps reduce duplicated data entry and transcription errors, while improving consistency and traceability between assessments.
The session also presented complementary approaches developed by two other European projects: MODERATE, which provides automated checks to identify errors and inconsistencies in EPC data, and OneClickRENO, which supports the development of Renovation Passports and staged renovation strategies through its renUEva tool.
Together, these examples illustrated how different digital solutions can contribute to a more consistent quality assurance process, from the initial EPC data collection and verification to the preparation of reliable Renovation Passports.
Eva Lucas Segarra also moderated the discussion Quality Control for Renovation Passports, which addressed specific quality control requirements for Renovation Passports, the importance of reliable baseline EPC information and the potential coordination of verification procedures across both instruments.
Contributing to effective EPBD implementation
iEPB’s participation in the Concerted Action EPBD highlighted the importance of reliable, interoperable and reusable building data as a foundation for improving building assessments, supporting renovation planning and facilitating the implementation of EU building policies.
By connecting different assessment instruments through a common data structure and enabling information to be managed and shared more consistently, iEPB aims to help building professionals, end-users and public authorities make better use of building performance information.
The discussions in Vienna provided a valuable opportunity to share these developments with national authorities and explore their potential contribution to the implementation of the EPBD across Europe.
