D^2EPC has analysed the quality and the drawbacks of the current EPC schemes, identifying technical challenges that currently exist and proposed means to overcome them. The adoption of the operational rating methodology is a forward-thinking move, as it shifts the focus from theoretical estimates to actual energy consumption data, providing a more accurate representation of a building’s energy performance. In this context, the creation of a new standardisation working group was achieved covering the operational rating of the energy performance of buildings, with D^2EPC members acting as Convenor (FRC) and Secretariat (UNE).
In addition, the D^2EPC project presented a series of indicators that address smart readiness, thermal comfort, and LCA dimensions, incorporating monetary and cost-optimum Key Performance Indicators (KPIs), providing stakeholders with a comprehensive understanding of building energy performance.
The project is based on BIM literacy, integrating smart meters, actual performance-related data and activities profiling into the buildings’ digital twins.
The project has succesfully delivered a holistic digital solution, the D^2EPC WebPlatform that not only issues the next generation EPCs, but also extends EPCs applications and usability. In particular, the Added value services include the provision of customised recommendations for energy performance upgrades (roadmapping tool), the provision of performance forecasting (AI-driven forecasting tool) and the provision of notifications and alerts (notifications and alerts tool). Further to that, the project provides extended applications that include buildings performance comparison in more than one normalised metrics as per the SRI framework as well as verifying the credibility of the data collection and processing. Furthermore, the D^2EPC WebGIS tool visualises generated EPCs in a GIS environment, empowering users to perform various types of spatial and attribute queries.
Two guidelines were developed, the generic guidelines for policy makers and the technical advisory for building professionals and end-users for successfully linking EPCs with building passports while the project lays forth a strategic framework encompassing four distinct award schemes for conscious energy users, incorporating penalties and award schemes that drew on successful theories and practices of the EU ETS.
D^2EPC scheme has been successfully validated and demonstrated under real-life conditions in six buildings in Greece, Germany, and Cyprus.
All members of the Consortium have worked closely together to identify and outline the project’s main exploitable results and the respective target groups. In overall, 9 main KERs have been identified while those can be further subdivided considering the different sub-modules of the Added value services suite and dEPCs Application Toolkit, reaching 12 KERs in total.
D^2EPC consortium utilized the Horizon Results Booster Service as well as the Horizon Results Platform for three KERs, allowing greater visibility and accessibility to interested parties.
