EPC RECAST will provide a sound process and toolbox supporting the development, implementation and validation of a new generation of the Energy Performance Certificate (EPC), one among the relevant instruments at the basis of renovation in existing buildings. It structures energy assessment, decision support on energy retrofit projects, development and articulation of financing instruments (public and private), benchmark of building assets and market value recognition. The goal is to improve such certification with a clear focus on residential buildings, for which retrofit is one of the most challenging and pressing issue nowadays at European level. A list of challenges still undermine the full potential of the EPCs as they are now, such as: the great variety of the assessment results (depending on the assessor, the input data and the calculation tools), the lack of understanding between predicted and actual energy performances, etc. In addition, an owner and occupant-centric vision should be at the basis of the new EPC design, allowing for a European benchmark and public policies analysis in a very heterogeneous context. Improving the EPC means unlocking confidence, decision support and articulation for financing in residential building. 7 European countries are represented by the 11 Partners of the Consortium, led by CSTB. EPC RECAST is a 40-month project started on 1 September 2020, with a total budget of about 2,751 M€. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 893118.
EPC RECAST will support the emergence of the next generation of regulatory Energy Performance Certificate (EPC), with the goal to better and further support professional EPC assessors to achieve improved EPC reliability, comparability in between building assets, user-friendliness and to actively involve owners and occupants in the pathway to efficient energy retrofit. This will be done also in consideration of the ongoing Digital Transformation, having big impacts in the building/construction sector, and the emergence of International Standards (e.g. the M/480 EN). More specific impacts are listed below: 1. Improved user-friendliness of EPCs in terms of clarity and accuracy of the information provided, across Member States, by exploiting a series of existing standards; 2. Enhanced user awareness of building energy efficiency by improving user-friendliness, thanks to a user-centered approach (as defined in ISO 9241-210); 3. On energy and investments side: up to 136,527 M€ deep renovation investment triggered per year, equal to 67,764 GWh/year of primary energy savings triggered and 195,181 MtCO2-eq/year reduction of greenhouse gas emissions in the period 2030 to 2050: 4. Contributions on new jobs created, improved quality of life of residential buildings inhabitants and inputs for key EU policies, e.g. the Revised (2018) EPBD – Energy Performance of Buildings Directive, as well as the Energy Union Strategy and the Clean Energy for All Europeans among others.
