The project brings together a consortium of leading universities and institutions from Spain, Italy, Cyprus, Albania, and Kosovo, with a shared goal of modernizing curricula in Renewable Energy Technologies (RETs) and Energy Efficiency (EE) applied to the building sector. Led by the University of Castilla-La Mancha (UCLM), the initiative addresses the pressing need to improve energy performance in Western Balkan countries and transition towards cleaner, more sustainable energy sources.
