2018 Summer School challenge Winners


In 2018, for the 6th International DHC+ Summer School edition in Ljubljana, we brought a new concept to the programme: the 24IdeaChallenge! The challenge was a reality-based problem designed by Danfoss and that was presented to the participants at the end of the week. The exercise was driven by the work and assessment hand-in-hand with experts and advisors in the field. Participants had the chance to suggest innovative solutions and the one feasible or the best one could have a chance to be implemented! The aim of this challenge is to create long-term partnerships between the participants and the industry. The winning team is at present on their way to implement their idea concretely within a plant in Slovenia.


As DHC+ Technology Platform is one of the major actor within the EU for education & trainings linked to District Heating and Cooling; we thought you might want to meet the winning team of this year challenge and young talents of the industry!


Congrats again to them with their innovation “Quick & Dirty LTDH”: Julijo Josip Franz, Peter Krizan, Nikola Matak and Susanne Tull.
