Sweden takes on the Ice Box Challenge: Building for a Sustainable Future

For the first time, students from five Swedish universities will participate in the international ICE BOX Challenge! In this competition, they will design and build the most sustainable and energy-efficient mini-houses.

I am incredibly proud to lead next year’s Swedish ICE BOX Challenge and excited to see the 10 unique boxes showcased in five different climates across Sweden on National Day, June 6, 2025.
