Guidelines to investigate users’ perception about EPC scheme

This deliverable lays the foundation to explore the perception of both groups on the EPCs understandability, usability, reliability, user-friendliness, cost-effectiveness, decision-driving potential etc., through a combination of qualitative and quantitative user-centred approaches, i.e. questionnaires, focus groups and interviews. Towards occupants it has the potential to make energy more intuitive and influence behaviour towards more responsible. The key idea is to understand the users' perspectives and to include them in making and improving EPC schemes. IRI-UL will set up the structure for interaction with the different EPCs users’ groups and test it in selected pilot actions with the national stakeholders and with the national associations representing the full range of EPC stakeholders. For an EU-wide application, the interaction strategy will be fine-tuned based on this on-field tests, a training for case holders will be prepared with clear guidelines and protocols how to conduct basic ethnographic inquiries will be given to the case holders.
