Project partners reveal the story behind the iEPB web application and the role of EPB standards in shaping Europe’s energy performance future

iEPB project is proud to announce the release of two new video interviews featuring leading partners behind its core developments. These video conversations offer insight into the creative and technical forces driving the project forward – from the web application architecture to the foundational EPB standards and energy performance frameworks.

Miguel Angel Pascual from Efinovatic is deeply involved in the design and development of the iEPB web application and he discusses how this digital tool is central to the project’s mission. The web app is one of iEPB’s primary results: a platform that enables the management, synchronization, and analysis of multiple EPB (Energy Performance Building) assessments across Member States (watch the interview).

The web application is currenlty in progress and will be launched soon, stay updated through iEPB’s social media channels and newsletter to discover it.

Andrei Litiu from EPB center delves into the longstanding collaboration among energy assessment specialists and explains their role in validating the calculation framework behind the iEPB schema. He reflects on their work to map the status quo of energy performance certification regimes in Austria, the Netherlands, and Spain – the three pilot countries – and outlines how the team is now contributing to guidance and specification strategies for Member States to transpose the EPBD recast of 2024 into national legislation (watch the interview).

The European Commission’s guidance documents, published in June 2025, provide the regulatory framework for Member States, which have until May 2026 to transpose the recast EPBD into national law. iEPB’s efforts are well timed to inform, support, and influence that transition across the EU.

Read more about the latest intense phase of work of iEPB

Exciting progress has been made on the iEPB project, with its common data model now successfully integrated into several key EPC and SRI tools across Spain, Austria, and the Netherlands. This integration is a major step forward in aligning with the 2024 Energy Performance of Buildings Directive (EPBD). In collaboration with the OneClickReno project, the model is also being extended to support personalized, step-by-step renovation recommendations.

Meanwhile, development of the iEPB web application has reached a key milestone, with the main architecture finalized and efforts now focused on visualizing integrated results. A notable new feature allows public authorities to aggregate and analyze data from multiple assessments through a single platform—supporting national compliance with EPBD Article 22. The platform is on track for testing in pilot buildings this autumn.

To ensure effective adoption, expert groups in Spain and Austria have been established to identify training needs for energy certifiers, laying the groundwork for tailored learning resources. At the same time, a pilot project on dynamic re-scaling in Spanish hotels—based on actual energy use—is underway, using real consumption data to produce more accurate performance assessments.

These developments were recently showcased at the CLIMA 2025 Next Gen EPC Cluster Workshop, where the iEPB project demonstrated its integrated approach across EPC, SRI, renovation passports, and LCA. While the technical development has revealed challenges—especially in managing shared datasets and creating flexible logic for varied scenarios—it has also confirmed the strong potential of this platform to enable immediate, practical implementation of the EPBD 2024.

ISSO leads development of a robust training programme to prepare Energy Performance Assessors for next-generation tools and EPBD IV implementation

The iEPB project is developing tools that support the alignment of various building performance assessments, with a particular focus on the efficient collection and reuse of data. To ensure that users can take full advantage of these tools, the iEPB team is creating a comprehensive training programme. The main goal of this programme is to equip Energy Performance Assessors (EPAs) to use the iEPB tools effectively within their local context. The training is expected to be finalised by mid-2026, aligning with both the release of the final iEPB tool versions and the required implementation of the EPBD IV in EU member states.

At present, ISSO is leading the training development task, beginning with a series of expert meetings. This first step involves gaining clear insights into the current skills, knowledge, and attitudes of Energy Performance Assessors in different national contexts — specifically in the Netherlands, Valencia (Spain), and Styria (Austria). These expert sessions have revealed valuable findings and highlighted notable differences between countries, for example in required competencies and the structure of EPA training. It has also been encouraging to see the high level of expertise and dedication among the participating experts.

The second step is to train a group of assessors — those involved in the pilot projects — in collaboration with ISSO, on how to use the iEPB tools. This training phase helps ISSO understand what specific knowledge, skills, and attitudes are necessary to use the tools to their full potential, especially regarding data management, sharing, and reuse.

The third step involves identifying the gaps — in other words, determining what knowledge, skills, and attitudes EPAs currently lack. These gaps will then be translated into a set of Units of Learning Outcomes (ULOs), which are scheduled to be completed by November 2025.

This structured three step process is based on ISSO’s extensive experience with earlier EU-funded projects and follows the standardised methodology developed under the Erasmus+ funded P4Elecs project. It aligns with recognised practices and resources, including referencing occupations as defined in the ESCO-database. Involving field experts remains essential, as their practical insights help define both the necessary and available competences, knowledge, and skills..

Based on the ULOs, ISSO will develop training materials that local trainers can use to create context-specific learning opportunities. The development of these materials will be closely coordinated with the tool developers (CENER and Efinovatic), ensuring a two-way exchange of feedback. This process ensures that both the tools and the training materials evolve in alignment with each other.

ISSO team members involved in this work are Lilibeth Juarez Rojas, Martijn van Bommel and Dirk de Wit. Project partners include the local implementation organisations — IVE and ATECYR in Spain, EASt and Ecotech in Austria, and Buro de Haan in the Netherlands — as well as the developers of the tools and methodologies.

New measures offer vital support for Member States and align with iEPB’s mission to accelerate energy efficiency in Europe’s building sector

The European Commission has presented a comprehensive package of documents to support EU Member States in the implementation of the revised Energy Performance of Buildings Directive (EPBD). This directive, a key element of the European Green Deal, aims to guide the buildings sector toward full decarbonisation by 2050.

The implementation package includes a tools for regulating cost-optimal energy performance levels, and data transfer to the EU Building Stock Observatory, and a detailed guidance document to help interpret and apply the revised directive. Together, these tools are designed to improve building energy performance, reduce energy bills, support the roll-out of renewables, and enhance competitiveness in the construction and cleantech sectors.

The package coincides with the first meeting of the new Housing Advisory Board, which will focus on sustainable, affordable housing and reducing energy costs.

As 85% of EU buildings were built before 2000 and the majority still perform poorly in terms of energy efficiency, the directive’s measures—ranging from stricter energy standards to improved financing—are vital for achieving the EU’s 2030 target of reducing energy consumption by 11.7%.

Since iEPB focuses on improving the implementation of the EPBD across Europe, it stands to benefit directly from this package. The new guidelines and common methodologies will provide a clearer framework for Member States, align national actions, and create synergies with iEPB’s mission to ensure a more consistent and effective application of EPBD provisions across Europe.

Making building assessments smarter, simpler, and ready for Europe’s green future, starting in Milan

At the recent “CLIMA 2025 – Practical Pathways to EPBD IV Implementation” workshop held in Milan from June 4-6,  iEPB stood out as a key initiative driving innovation in the integration of Energy Performance Certificates (EPC), Smart Readiness Indicators (SRI), Renovation Passports (RP), and Life Cycle Assessment (LCA).

The event brought together leading EU-funded projects to explore practical and coordinated strategies for implementing the recast Energy Performance of Buildings Directive. Represented by IVE and EPB Center, iEPB presented its common data model, web application, and SRI standalone tool – all designed to harmonize and streamline building assessment processes across Europe.

iEPB’s approach addresses a major market need: enabling professionals to conduct multiple building assessments (EPC, SRI, RP, LCA) in a single visit using a shared digital infrastructure. By promoting a unified data structure and user-friendly interfaces for both experts and building owners, the project contributes directly to the goals of EPBD IV—especially in the areas of  data exchange, digital building logbooks, and national energy databases.

The workshop highlighted how iEPB supports smarter renovation decisions, facilitates compliance with new policy requirements, and encourages the adoption of digital tools in the building sector. As Europe moves toward a more decarbonized and data-driven future for its buildings, iEPB is playing a pivotal role in making integrated, user-centered, and scalable solutions a reality.

iEPB's partners champion a common data model and integrated accreditation pathways for smarter energy performance certificates

iEPB attended the yearly Next Gen EPC Cluster meeting in Brussels on May 6th, 2025. This year, the meeting was organised by the Smart Living EPC project and REHVA. During the meeting, the projects included Next Gen EPC cluster that will be ending this year presented their results, including insights that are useful for the ongoing projects in the cluster and the implementation of the EPC Recast.

Buildings drive much of Europe’s energy use and emissions, and digital tools are key to meeting the EU’s climate targets: during the event, it was highlighted how to use innovative digital solutions to improve building energy performance and certification. Policymakers, researchers and industry leaders all gathered together to discuss project outcomes, EU strategies and the social hurdles to widespread digital adoption.

The agenda was very rich in presentations and panels, thus highlighintg both the uniqueness of each research’s project and institution and the benefits of clustering and collaborating.

iEPB was represented by Dirk de Wit from ISSO and Jaap Hogeling and Andrei Lițiu from EPB Center and they specifically brought to the table the value of a common data model for EPCs, SRIs and other instruments. The three partners gave a sneak-peak of the results that they expect to present in the next edition of the next Next GEN EPC Cluster meeting. They also focused on the issue of how to certify- in the sense of accreditation-  integrated assessments and assessment tools as well as assessors who are using these tools.
