Uneven implementation of energy performance certificates (EPCs) across EU Member States could undermine efforts to implement the Green Deal.

As a result, a consortium of 13 project partners from 9 countries representing 43 per cent of the EU population has formed to regulate EPCs, the new Horizon 2020 project X-tendo has created a next-generation of EPCs and supporting public authorities in the nine countries is recasting their existing EPC schemes.

The H2020 project X-tendo, standing for ‘eXTENDing the energy performance assessment and certification schemes via a mOdular approach’, will support public authorities and implementing agencies in the transition towards improved compliance, reliability, usability and convergence of next-generation energy performance assessment and certification.

How will X-tendo reach this objective? By designing a modular web-based toolbox, containing 10 potential features of the next-generation EPC. These are: smart readiness indicator, comfort, outdoor air pollution, real energy consumption, district heating, EPC databases, building logbook, tailored recommendations, financing options and one stop shops. The features will be developed and tested in 9 countries around Europe (Austria, UK, Italy, Denmark, Estonia, Belgium, Portugal, Poland and Greece). The “harmonised” implementation of the next-generation EPC features will contribute to a gradual convergence of EPC schemes across Europe and eventually act as a catalyst for energy renovations in Europe.

The 13 project partners are: TU Wien (AT), the Energy Saving Trust (UK), Enea (IT), EASt (AT), Danish Energy Agency (DK), TREA (EE), VITO (BE), AAECR (RO), e-think (AT), BPIE (BE), ADENE (PT), NAPE (PL), CRES (GR).
