Unit of Energy Efficient Building presents current research at ISEC 2026 in Graz

A small but energetic delegation from the Unit of Energy Efficient Building at the University of Innsbruck attended the 4th International Sustainable Energy Conference (ISEC) in Graz from 14 to 16 April.


With three presentations and five posters, we shared our latest work on energy-efficient and sustainable building research. Many thanks to AEE INTEC for the excellent organisation and warm hospitality.

Between inspiring discussions and Styrian charm, the days flew by. We returned to Innsbruck motivated and full of new impulses.
