EVELIXIA GeoWall Showcased at the World Congress on Energy Geostructures
The built environment can do more than consume energy. By integrating renewable energy technologies directly into buildings, structural elements themselves can become part of a more sustainable and flexible energy system.
This potential was highlighted at the 1st World Congress on Energy Geostructures & FOLIAGE Meeting, held on 3 September 2026 at the Technical University of Cluj-Napoca (TUCN), Romania, bringing together more than 100 participants.
During his keynote, Prof. Dan Micu, EVELIXIA project coordinator from TUCN, explored the role of energy geostructures within the broader renewable energy transition. His presentation addressed the challenges, synergies and opportunities associated with rethinking the role of the built environment in a sustainable energy future.
A key example was the GeoWall installed at the EVELIXIA TUCN pilot site in Cluj-Napoca. The system uses the building’s ground-contact structure to exchange heat with the surrounding soil, providing a source of renewable thermal energy.
Within the EVELIXIA pilot, the GeoWall operates alongside Building-Integrated Photovoltaics (BIPV) and IoT monitoring, bringing different technologies together as part of a grid-interactive building energy system.
By showcasing the GeoWall at the congress, the TUCN team demonstrated how EVELIXIA is exploring new ways to integrate renewable energy generation, building infrastructure and smart energy management to support the transition towards more sustainable buildings.
