Next Gen EPCert cluster

3 Coordination and Support Actions (CSA) started in 2019 (H2020_LC-SC3-EE-5-2019)

There is room for improvement in terms of energy savings in the building sector, particularly through the refurbishment of Europe’s existing building stock. Amongst the measures introduced in the EU to boost energy savings is EPC, providing buildings and owners with an incentive to invest in improving energy efficiency. The EU-funded QualDeEPC project aims to improve both the quality and cross-EU convergence of EPC schemes and the link between EPCs and deep renovation. It will improve the practical implementation of the assessment, issuance, design, and use of EPCs as well as their renovation recommendations. The project will promote dialogue involving stakeholders at all levels.

From 1 September 2019 to 31 August 2022


X-tendo will support public authorities to transition to next-generation EPC schemes, including improved compliance, reliability, usability, and convergence. The key output of the project will be the X-tendo toolbox, a freely available online knowledge hub that will be continued also beyond the project duration. It will contain 10 innovative EPC features ranging from a smartness and a comfort indicator to building logbooks and how to improve EPC databases.

U-CERT aims to introduce the next generation of user-centred certification schemes to value buildings in a holistic and cost-effective manner. It wants to facilitate the convergence of quality and reliability, under the M480 mandate developed national annexes standards, enabling a technology-neutral approach that is transparently presented. It encourages the development and application of holistic user-centred innovative solutions, including the smart readiness of buildings. As well, it supports end-users in decision-making (e.g., on deep renovation). U-CERT focuses on strengthening the actual implementation of the EPBD by providing insights from a user perspective and creating a levelled playing field for sharing implementation experience, to all involved stakeholders, facilitated by the EPB-center.

ePANACEA works on developing a new, holistic, more reliable, user-friendly and cost-effective methodology for energy performance assessment and certification of buildings. It aims to make use of the most advanced techniques in dynamic and automated simulation modelling, big data analysis and machine learning, inverse modelling or the estimation of potential energy savings and economic viability check, to support the energy transition through the buildings sector.

From 1 June 2020 to 31 May 2023


E-DYCE (Energy flexible DYnamic building CErtification) is the natural evolution of the conventional Energy Performance Certification into real-time optimization of building performance and comfort, by capturing the building’s dynamic behaviour, and at the same time providing transparent feedback, through an intuitive interface.


D^2EPC project ambitiously aims to set the grounds for the next generation dynamic EPCs. The proposed framework engages actual measured data coming from smart devices and introduces a set of novel and user-friendly indicators by employing 6D Level 3 BIM for producing a building’s digital twin representation. The proposed indicators for smart-readiness, sustainability, environmental, human comfort and financial aspects will make EPCs a realistic, accurate and comprehensive information source that can induce energy efficient behavioural change and stimulate smart buildings.


EPC RECAST sets a well-structured process and a toolbox supporting the development, implementation and validation of a new generation of Energy Performance Assessment and Certification, with a deliberate focus on residential buildings, more specifically existing ones, for which retrofit is one of the most challenging and pressing issues. By enhancing EPCs usability, reliability, and comparability, and by linking them to renovation roadmaps and building digital notebooks, EPC RECAST can achieve unprecedented user-friendliness and user awareness of building performance.

The crossCert project will create a product testing methodology for the new EPC approaches that will result in improved accuracy and usability of the EPCs, people-centric designs, and increased homogeneity across Europe. The crossCert project is based on a bottom-up approach, with the following stages: (1) Cross-testing among energy authorities of current EPCs and the new approaches/concepts/initiatives, using more than 140 buildings in 10 European countries, and creating a public benchmarking repository of test cases; (2) Comparing and analysing the results between different approaches; (3) Elaboration of policy recommendations, which will include potential improvements on the accuracy, usability, and harmonisation; (4) Engaging networks and alliances for analysis and (5) for outreach.

Do you know what kind of data one can get by just observing buildings with the right tools? A LOT. And it’s up to us to draw the limits. The issue currently faced is that to find a way to commonly assess and certify buildings. A way that is valid and consistent across all EU Member States. And this is what EUB SuperHub will do. How? By scanning and studying the current energy assessment schemes and certification methods available in the EU, and by developing common criteria to support the market penetration of certificates.

iBRoad aims at exploring, designing, developing, and demonstrating the concept of individual Building Renovation Roadmaps. With the innovative approach proposed, the project aims to become a real driver for deep renovation. Representing an evolution of the Energy Performance Certificates (EPCs) and energy audit systems, building renovation roadmaps will serve as a tool outlining a customised renovation plan with a long-term horizon for a deep step-by-step renovation of individual buildings (iBRoad-Plan), combined with a repository of building-related information (logbook, iBRoad-Log).

From 1 September 2021 to 31 August 2024


TIMEPAC will help improve existing energy certification processes and move from single, static certification to more holistic and dynamic approaches. At five demonstration sites, TIMEPAC is developing new methods and tools to provide an improved basis for data collection and analysis. As a result, Energy Performance Certificates will be enriched with concrete retrofitting solutions and experts can be better trained to make our homes fit for the future.

From 1 July 2021 to 30 June 2024

How energy performance certificates support the deep renovation

QualDeEPC has had its final conference on how Energy Performance Certification can support the deep renovation. Read more about the conclusions in this article.

QualDeEPC discussed national and EU policy recommendations

At the third round of national work-shops, QualDeEPC discussed national ad EU policy recommendations and gained feedback from experienced practitioners on the nationally adapted concepts of enhanced EPC Schemes.

Cross-assessment and convergence of energy performance certification and building’s digitalisation

Data on energy performance of buildings are precious for accelerating the EU renovation wave. Considered as a first tool to trigger action, Energy Performance Certification has gained a lot of attention lately, with projects working on making their assessment and use more efficient, developing their data accessibility with intelligence, and exploring convergence among the different national EPC schemes. What can we take out from some of these projects?
