D 2EPC: Next Generation Digital and Dynamic Energy Performance Certificates

Energy performance of the building stock has been identified as one of the core challenges in the effort towards improving not only energy efficiency, but also achieving zero and positive energy buildings. With the recast of the Energy Performance of Buildings Directive, Europe has made clear that improved schemes are required for more accurate assessment of the actual energy performance, exploring in a holistic approach the factors that affect both asset and operational rating. Towards that direction, a lot of research endeavours have been denoted in order to identify the additional information required and the necessary cutting-edge digital technologies that will not only enrich the energy performance certification process but will at the same time facilitate and accelerate related procedures while also presenting more context to the users, raising understanding, awareness, and hence actual engagement. The D2EPC project presents a solution that covers the main current challenges and gaps in the assessment process, introducing a variety of improvements, in terms of information (i.e. energy, smart readiness, well-being, comfort, financial, and sustainability indicators) with the use of advanced tools (i.e., Building Information Modelling, Geographic Information Systems, etc.). The present work, introduces a high-level representation of the D2EPC architecture, elaborating on individual components and their interaction, towards delivering the envisioned final enriched web-platform that will enable dynamic Energy Performance Certificates based on (near)real-time field data.
