The Solar Decathlon Europe is a competition based on 10 different contests; from engineering & construction to innovation, energy performance and affordability & viability. The goal of the competition is to develop innovative solutions to address the technical, architectural and social challenges the cities of today are facing. Therefore, SUM is developing a highly energy-efficient solar-powered dwelling, focussing on modularity, circularity and sustainability. For the competition, we need to build a 1:1 prototype part of our building design.
