The challenges for the European countries to implement nearly zero-energy buildings and achieving minimum shares of renewable energy are tremendous. There are various indications raising concerns regarding the reliability of Energy Performance Certificate (EPC) declarations and the quality of the works. Achieving a significant improvement requires strong commitment from authorities and other major players, as well as sufficiently broad societal support. QUALICHeCK responds to these challenges by: identifying issues in respect to existing procedures; highlighting best practices for easy access to reliable EPC input data, delivery of improved quality of the works, as well as more effective compliance frameworks (“lead people to do what they declare”); and raising awareness and engaging relevant stakeholders. The focus of the activities is mainly (but not limited) on 9 countries (Austria, Belgium, Cyprus, Estonia, France, Greece, Romania, Spain and Sweden and four technology areas: transmission characteristics, ventilation and airtightness, sustainable summer comfort technologies and renewables in multi-energy systems. Particular attention is given to stimulation of innovation. The presentation presents the available outcomes, including the draft version of the source book on compliance. Interactive voting with the participants is used to increase the dynamics of the workshop.
