Features of the energy performance certificate (EPC) must be accepted by users in order to be used. Acceptance is influenced by different factors. For example, whether a technology is easy to use and appears useful. However, today's EPCs are rarely actually used. More often, they are put in the drawer as a mandatory document because they appear standardised. One of the objectives of the Horizon 2020 ePANACEA project is designing new EPC summary sheets that are accepted by end-users, providing information that is easy to understand and useful. 

Within the framework of this task online user-acceptance workshops were conducted in the five ePANACEA pilot countries (Spain, Belgium/Flanders, Finland, Austria and Greece) to test users’ acceptance of proposals for new EPC summary sheets. The main target group for the acceptance workshops are end-users of EPCs (i.e. tenants, building owners, occupants etc.); nevertheless, a number of participants also had a technical background in energy efficiency in buildings.
