The aim of X-tendo is to support public authorities in the transition towards improved compliance, reliability, usability and convergence of next-generation energy performance assessment and certification.
To date, the implementation of energy performance certificates (EPCs) varies significantly across Member States in terms of scope and available information, resulting in some cases in limited reliability, compliance, market penetration or acceptance by the users. Aspects like smart dimension or the interaction with the district energy system are insufficiently covered in current EPC schemes. In order to become a catalyst for energy renovations, the next-generation EPC must provide an improved and more reliable service to the end-users
By considering the strengths and weaknesses of current EPC schemes according to their effect on the market, end users and the society, and looking into possible additions and improvements to these schemes, X-tendo will develop a modular web-based toolbox. The toolbox will cover different features of innovative indicators as well as innovative data handling approaches. A selection of relevant test projects will demonstrate the potential of the developed toolbox to deliver more reliable next-generation EPC schemes across the EU.
The X-tendo’s next generation EPC features are Smart Readiness Indicator, comfort, outdoor air pollution, real energy consumption, district heating, EPC databases, building logbook, tailored recommendations, financing options, one stop shops. The features, together with their development and test processes should meet the four cross-cutting criteria: (i) Good quality and reliability of EPCs; (ii) User-friendliness; (iii) Economic feasibility; (iv) Consistency with ISO/CEN standards.
X-tendo brings together a highly experienced consortium of four specialist institutions in technical and communication activities and organisations involved in implementing EPC schemes in nine countries (Austria, Estonia, Greece, Romania, Portugal, Italy, Denmark, United Kingdom, Poland).
The project is funded by the European Union under the Horizon 2020 - Research and Innovation - Grant Agreement No 845958.
