What is the Solar Decathlon Europe 21?

The SDE21 is a university competition for urban building and living. It takes place in Wuppertal in June 2022 and puts innovative ideas for sustainable architecture into practice. The aim is to develop appropriate solutions for technical, architectural and social challenges facing our European cities.

Meet the teams

Eighteen teams from eleven countries have qualified for the Solar Decathlon Europe 21. ‘Design – build – operate’ is the principle. The teams will therefore not only develop innovative housing ideas, but will actually realise their designs, which will be fully-functional one- or two-storey residential houses.
