The “reZEB” project focuses on modernizing and developing new curricula in Renewable Energy Technologies (RETs) and Energy Efficiency (EE) for buildings in the Western Balkans. Aiming to contribute to near Zero Energy Buildings (NZEB) in the region, the project addresses the need for skilled professionals by aligning education with EU standards and industry demands. It updates existing courses, creates new modules, and enhances teaching methods with ICT-based practices to provide a dynamic learning environment. The project also emphasizes practical experience through strong partnerships with local industries, helping to bridge the gap between academia and the labor market. By fostering long-term collaborations and knowledge exchange, reZEB aims to ensure the sustainable development of the renewable energy sector in the Western Balkans.
