This report analyses the role and relationship of Next Generation EPCs (NG EPCs) in the Energy Performance of Buildings Directive (EPBD) and examines whether there are any existing constraints to their implementation in European countries. It also highlights the current state of implementation of key aspects of the EPBD and the use of the EPCs in the countries of the project consortium partners.
To collect the relevant information for this task, a questionnaire was prepared and sent to the partner countries at the beginning of the research.
In addition, the main policy benefits of NG EPCs in the EU and the project-participating countries (e.g. real-time energy consumption instead of theoretical values) on a policy level were identified (taking into account the results of the work within the project). They will then be weighed against market acceptance and user-friendliness, costs and benefits, and readiness and training of EPC issuers.
To this end, the partners have collected information on the usability of existing EPC systems and their links to national/regional EPC databases (including structure, interfaces, etc.). As part of this task, the stakeholders at the national/regional level were identified and invited to share information and discuss the project results. These workshops took place during the second phase of the project when interim results were available. In these workshops, the characteristics of the NG EPCs and related benefits were presented. The results of these workshops serve as an evaluation of the proposed framework for the next-generation dynamic digital EPC as envisaged by the D^2EPC project. In addition to the benefits of the dynamic and digital EPC compared to the established EPC systems and its integration into national/regional strategies and recommendations, the results of the aforementioned workshops have been included in this report.
