Energy Performance Certificates (EPCs) are a mandatory requirement in the Member States when constructing, selling, or renting a building. This report identifies the methodologies currently used for the issuance of EPCs on a European level, explores the technological and market conditions where D^2EPC will be realized, as well as investigates the challenges of current EPC schemes.
The methodology followed in this report consists of field research committed as a set of statements with questions relevant to challenging matters of (i) EPCs issuing, quality and control, (ii) EPCs calculation software and tools, (iii) EPCs indicators, and (iv) Qualified experts competence and skills, and desk research committed as a set of statements with questions relevant to challenging matters of EPCs. Concerning the field research, the extraction and circulation of a questionnaire to a list of stakeholders took place.
The collective analysis of data for the specific features of EPCs revealed that among the twenty-seven (27) EU Member States, fourteen (14) have adopted the methodology exclusively based on calculated energy consumption. Penalties are rare and are mainly addressed to energy auditors. Based on the research of this report, it was revealed that the majority of EU countries do not employ by any means BIM documentation and literacy or digital logbooks for the issuance of EPCs. There is no provision, national requirement, or legal obligation of a Building Management System (BMS) existence in connection with the operational EPCs, and in most of the EU Member States information related to Geographic Information System (GIS) is not included in the EPCs, and consequently, it is not exploited for issuing, validating, monitoring, and verification processes of the EPC calculation. Additionally, analysis across the EU Member States revealed that energy-related financial indicators, as well as environmental/LCA related financial indicators, are not found to be included in current EPCs schemes and procedures in any EU Member State. Although provisions for indoor environmental quality are set in EPCs, there are not covered in current EPC regimes and are not included in the calculation procedure for certification of EU countries. There is no existence of a database describing the energy efficiency features of the building stock as a whole. One-third of EU countries do not have provision for systematic and regular evaluation/assessment of energy assessor’s competence and skills.
