Social and Community Objectives
DECODIT has established four Living Labs across its demo sites in Greece, Latvia, Spain, and Switzerland, actively fostering digital and energy literacy. Through co-creation workshops, citizens and stakeholders help design digital tools tailored to local habits and cultures, ensuring practical, inclusive solutions. Localized learning materials, interactive sessions, and energy literacy surveys boost awareness, while reflective diaries and customized activities are utilised to design efficient behaviour solutions.
The project’s outreach is also steadily improving. DECODIT is surpassing its goals, contributing to over 20 conferences, 6 workshops, and collaborating on 3 joint webinars and 5 joint workshops with partner initiatives. It produced 30 non-scientific articles and 10 podcast episodes. Approximately 10,000 people have been reached through the dissemination and communication activities.
Technical, Financial and Digital Infrastructure Objectives
DECODIT’s first version of data exchange architecture is now live, built on the open-source Eclipse Dataspace Connector (EDC) and compliant with the latest IDSA Dataspace Protocol. Deployed as a Connector-as-a-Service, it ensures interoperability with other dataspaces like the Common European Energy Dataspace (CEEDS). The architecture integrates the Consumer Digital Twin (CDT) and the Empowered Citizen App (ECA), which will provide personalized energy recommendations—such as consumption insights, optimization, and financing—based on the Common European Reference Framework (CERF). Semantic interoperability is enabled through standardized schemas like BIM and Brick ontology.
The project has defined eleven Use Cases across five CERF clusters, focusing on energy savings, consumer engagement, and data-driven insights. These include energy cost reduction, carbon footprint awareness, home energy management, flexibility market participation, and smart EV charging. The ECA interface, already prototyped, will serve as the main user interface, powered by the AI agent NRGenii, which delivers multilingual recommendations using data from the CDT and integrated toolboxes. Initial versions of key toolboxes—Renovation Support (RST), Energy Management (EMT), and Financing (FT) — are operational. The RST offers data-driven renovation guidance, the EMT enables cross-domain energy optimization, and the FT supports risk-informed financing for residential renovations. The FT includes a credit-scoring engine to validate financial data and compute key indicators, enabling personalized underwriting. The focus now is on refining these services into a complete platform for personalized energy efficiency and cost savings.
Validation Objectives
DECODIT is validating its digital energy solutions across four Living Labs, each representing diverse household profiles and energy behaviors. Three labs are fully operational, with Latvia nearing completion. In Greece, CoEn activated an energy community and expanded IoT and BIM infrastructure. Switzerland’s AEM integrated smart assets and BIM models, enhancing data interoperability and e-mobility support. Latvia analyzed modern building systems and initiated BIM and sensor plans, while Spain’s LaSolar cooperative leveraged prior project experience to onboard users and upgrade IoT infrastructure. Progress across labs sets the stage for toolbox deployment and KPI validation, ensuring the project’s solutions are both scalable and adaptable to local needs.
