REA North, in cooperation with the Faculty of Civil Engineering and Architecture in Osijek, held a Renovation training on Friday, September 26, 2025, focused on thermal bridges and air tightness in buildings.
Renovation trainings are planned as capacity-building activities on planning, contracting, and monitoring renovations of public buildings and the one organized in Osijek brought together designers, engineers, and public administration officials, who had the opportunity to learn about the types, impacts, assessment methods, and identification of thermal bridges through practical case examples.
In addition, they gained new knowledge on thermal bridge calculations and the risks of their occurrence in cases of underperforming renovation. The training also addressed the topic of air tightness in buildings and the importance of achieving a continuously insulated building envelope.
After the theoretical part on thermal bridges and air tightness, participants were introduced to the air tightness testing method through a demonstration of the Blower-door test, which showed how to detect air “leakage” and possible solutions.
In addition to the training held in Osijek, REA North will organize two more renovation trainings with the aim of strengthening capacities for the implementation of effective energy renovations.
Renovation training was organized as part of the activities of the OUR-CEE – Overcoming Underperforming Renovations in Central and Eastern Europe project, which addresses the challenges of underperforming energy renovations and how to overome it in the Central and Eastern Europe region.
The project is implemented with the financial support of the EUKI (European Climate Initiative) program.
