iBRoad2EPC project

Integrating Building Renovation Passports into Energy Performance Certification schemes for a decarbonised building stock

We're Here To Help Your Business

In support of the Renovation Wave

iBRoad2EPC builds on the results of the iBRoad project (2017-2020) which developed, tested and delivered a model for the Building Renovation Passport (BRP) supporting single-family home-owners with personalised advice to facilitate stepwise deep renovation of their buildings. iBRoad2EPC aims to bridge the Building Renovation Passport with the Energy Performance Certificate (EPC), and expand, improve and broaden their format and joint scope to consider additional features, e.g., indoor environment and smart technologies, and become applicable also to multi-family and public buildings. The aim is to improve reliability, usefulness and effectiveness, thereby establishing the next generation of EPCs that will support Europe’s decarbonisation ambitions as reflected in the Renovation Wave Strategy, while improving conditions for building occupants.

the adoption of the iBRoad2EPC model beyond the pilot countries, as a catalyst for the deep renovation of the European building stock.

From iBRoad to iBRoad2EPC

The iBRoad2EPC project builds on the achievements of iBRoad, broadens the scope of the concept and adapts it to national EPC schemes, to prepare the roll out of next generation EPCs in Bulgaria, Greece, Poland, Portugal, Romania and Spain.

At least 3 countries are expected to take up the integration of the BRP with the EPC in their national frameworks within the iBRoad2EPC project context, to improve the EPC’s reliability and value. This would increase building renovation depth by 30%, the number of renovations by 5% and achieve 51% final energy savings and 8.2 GWh/year primary energy savings.

The greater context

Game changers for deep renovation

Roughly 75% of European buildings are considered inefficient energy-wise, while up to 97% have a significant potential for further improvement. The European Commission has published the Renovation Wave Strategy to boost building renovation for climate neutrality and recovery. The objective is to at least double the annual energy renovation rate of buildings by 2030 and to foster deep energy renovations..

Building Renovation Passports (BRPs)

Stepwise deep renovation of an existing building is possible, but a plan –such as that presented in a BRP– is needed to ensure the full potential is reached.

Digital Building Logbooks (DBLs)

Similarly, a DBL brings together all building-related information, supporting initial assessment, and monitoring of renovation progress and improved performance.  


Energy Performance Certificates (EPCs) are already a cornerstone of EU’s building policy, and can evolve further to catalyse deep renovation.

Advance praise for iBRoad2EPC

The Directorate General for Urban Agenda and Architecture believes the scope of iBRoad2EPC would be very relevant for examination and possibly integration in the Spanish context.

The Sofia Energy Agency supports the idea of expansion of the national Energy Performance Certification (EPC) scheme to integrate a building-specific customised renovation plan and other relevant features.
