Periodic Reporting for period 1 - EVELIXIA (Smart Grid-Efficient Interactive Buildings)

Reporting period: 2023-10-01 to 2025-03-31

Summary of the context and overall objectives of the project

The EVELIXIA project aims to rethink how buildings interact with the energy system—not as passive structures, but as active contributors to energy flexibility and grid stability. Today, most buildings consume energy without regard to when or how it’s produced. But with the rise of rooftop solar, electric vehicles, and smart appliances, this model is becoming outdated.

In this project, buildings will be equipped to not only consume energy efficiently, but also to communicate with the grid, respond to energy signals, and shift their energy use in ways that support the wider system. This means using stored solar energy when it's most needed, charging EVs when demand is low, and even selling energy back to the grid or sharing it with neighbors.

To make this vision a reality, EVELIXIA brings together 36 partners across 12 European countries. Together, they are developing and testing new services that allow buildings to reduce emissions, cut energy waste, and boost their share of renewable energy. These innovations will be tested in real buildings—from homes to public spaces—across seven pilot sites, helping to show how future-ready buildings can be smart, flexible, and deeply connected to the energy ecosystem around them.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

During its first reporitng period (M1-M18), the EVELIXIA project laid the groundwork for a new generation of smart, connected buildings. More specifically, the progress included the establishment of the EVELIXIA platform’s foundational architecture, integrating critical components such as the Autonomous Building Digital Twin (ABDT), Autonomous District Digital Twin (ADDT) and Stakeholders Interaction Platform (SIP).
Early integration of blockchain technology enabled secure data handling and set the stage for smart contracts and decentralized identity features.

At the same time, sginigicant progress was made on the ground. Pilot sites across Europe were surveyed and prepared, with initial use cases defined and tested. Innovative building technologies—ranging from next-gen storage systems to adaptive building envelopes—began deployment, supported by efforts to ensure that data flows securely and efficiently between systems.

Beyond the technical side, the project engaged stakeholders through workshops and surveys, shaping its tools around real user needs. It also began exploring how these solutions could scale beyond the pilots, identifying regulatory hurdles and market pathways. In the months ahead, EVELIXIA will focus on integrating its platform across sites, refining business models, and preparing the solutions for broader adoption—turning buildings into active players in a flexible, sustainable energy future.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

This section is not applicable at this stage, as the project is still within its first reporting period. Results are primarily preparatory and foundational, with impact assessment and exploitation planning to be addressed in subsequent phases.
