5 original retrofit projects from around the world by the experts of tomorrow
At the international Solar Decathlon Europe competition, students compete in ingenuity to think about construction in a sustainable and inventive way. From Taiwan to Sweden, let’s focus on the most innovative projects of this edition!
The team: Team Sweden
The school: Chalmers University of Technology, Gothenburg
The project: In the heart of the city of Gothenburg, the students of Team Sweden spotted a typical 1970s supermarket that was rather discreet. This was the ideal place to test their intuition: due to their size and age, this kind of soulless building will easily be suitable for renovations and changes of use in the medium term. The idea here consists of building a structure on the roof that will mix housing and workspaces. Called C-Hive, this extra height project must obviously consider several constraints such as the weight of the new structure, hence the choice of light materials.
The structure of C-Hive will be made out of wood but will also benefit from 3D cellulose printing. Through this revolutionary process developed at their university, students will be able to have reusable ‘printed wood’ parts designed to order. This resource will come from the recycling of waste from the Swedish forestry industry, which seems logical: the design of the building is inspired by trees, with clear references between walls and trunks, façade and bark, roof, and canopy. Team Sweden uses the plant metaphor to sum up their project: ‘like a mushroom sprouting from the ground, the new grows on top of the old’.

All the other projects in the competition can be found on the Solar Decathlon website. As the name suggests, the Solar Decathlon is based on ten events, including architecture, engineering, energy efficiency, innovation, and financial viability. An international jury is responsible for selecting the winning team.
