Under the motto "Design - Build - Operate", university teams from all over the world came together to compete in the Solar Decathlon, an urban contest for sustainable building. In addition to an overall design for a building project, the participants have constructed characteristic building parts in original size on the Solar Campus in Wuppertal - impressing and inspiring more than 115,000 visitors.

Up high: Team RoofKIT stocks up buildings

The participants were not only able to learn from and connect with each other, but also take home various prizes. The first prize was finally won by the project "RoofKIT". The project from Karlsruhe shows how cities can be built in a sustainable, environmentally friendly and socially acceptable way. To achieve this, the students are rethinking previously unused roof space - and stocking it up. The RoofKIT concept is an urban planning blueprint for previously unused spaces in the city, as the team emphasizes. Since 2020, more than 100 students from various KIT faculties have worked on the project.

Eight houses of the SDE 21/22 will remain on the grounds for at least three years and serve as part of the follow-up project "Living Lab NRW" for research and education. The RoofKIT team will also continue to use the demonstration house. It will be dismantled in Wuppertal and rebuilt at the Karlsruhe Institute of Technology. There, the building will also be used for research purposes. Successively, more and more real consumers will be integrated. Another interesting project was developed by the LOCAL+ team from Aachen, which has advanced a concept for single people who prefer to live in a community.

During the Solar Decathlon Europe 21/22, numerous out-of-contest awards were presented in addition to the main competition: These included the "Solar Award", which was offered by the IEA Solar Heating and Cooling Programme together with the International Solar Energy Society. The solar prize awarded two very convincing and applicable solar integration concepts. The first solar prize went to the VIRTUe team from Eindhoven University of Technology in the Netherlands and the second solar prize was received by the LOCAL+ student group.
