On 22 April 2025, as part of the 3DIVERSE project, an online workshop titled “Unlocking the Potential of 3DIVERSE Results” was held, where key project outcomes were presented to stakeholders. The event gathered participants from across the region, including representatives from Croatia, Bosnia and Herzegovina, and North Macedonia. The workshop aimed to share knowledge, experiences, and solutions related to the green transition of the coal-dependent Savinjsko-Šaleška region.
In the opening presentation, Nejc Jurko, KSSENA introduced the project’s strategic goals, which include building renovation, zero-emission mobility, renewable energy integration, and innovative financing tools to support decarbonisation. The broader goal is to develop a replicable investment model for other coal-dependent regions in Europe.
The presentations that followed showcased both technical innovations and citizen-focused tools developed through the project.
Katja Klinar, University of Ljubljana, Faculty of Mechanical Engineering presented the DisCoNetHeat tool, which uses data analysis to predict which consumers may disconnect from the district heating system—helping providers act early to prevent rising costs and inefficiencies.
After exploring user behavior and disconnection risks, the next presentation focused on technical improvements to enhance the efficiency of district heating infrastructure.
Marko Keber, University of Ljubljana, Faculty of Mechanical Engineering introduced the DHNpype simulation tool, which helps identify areas of heat loss in old heating networks. In the case of Velenje, the tool showed that smart renovations could improve system efficiency by up to 80%.
Klemen Peter Kosovinc, Kolektor sETup presented a digital twin used to simulate and optimize future energy systems. By testing different setups and energy price scenarios, the tool helps planners design reliable and cost-efficient energy infrastructure.
Niko Natek, KSSENA then introduced a blockchain-based token system that rewards citizens for energy-saving actions. The system is being gradually rolled out, with the goal of encouraging broader public engagement in sustainable practices.
Participants also took part in a live Mentimeter poll, where they rated the simulation of district heating upgrades and digital twin tools as the most impactful solutions. Feedback confirmed that the workshop helped improve understanding of the transition process in coal-reliant regions.
