Solar Decathlon 21 postponed

​​​​​​​​​​​​​Student competition Solar Decathlon postponed to June 2022

The Solar Decathlon Europe 21 in Wuppertal has been rescheduled. The decision to delay the international university competition, due to take place in September 2021, is a reaction to the current COVID-19 pandemic. A new date has been set for June 2022.

Due to the worldwide spread of the coronavirus, the organizing team of the Solar Decathlon 21 (SDE21) decided to delay the student competition for sustainable architecture planned in Wuppertal. Now the final takes place in June 2022.

According to a press release of the hosts, the decision was made in close cooperation with the participating teams and the cooperating partners.

«It would have been difficult to host a major event that involves 18 teams from eleven countries and attracts large numbers of visitors in 2021. However, our main reason to postpone the competition is that the current situation significantly affects the quantity and quality of the teams’ contributions»,

Dr. Daniel Lorberg, head of the project

Team MIMO of HSD in digital mode

The pandemic also thwarted the team MIMO of HSD. The schedule and organization of the Solar Decathlon team from Düsseldorf were adopted at short notice, some decisions had to be made in a hurry. But the student team used the spring 2020 to hone drafts, develop ideas further and to increase the team’s size.

Ensure a fair competition

As coronavirus measures vary from country to country, some teams are more strongly affected by the current situation than others.

«The SDE21 schedule is very tight. The teams have less than two years to design an entire building and to construct one representative residential unit in Wuppertal […] Thanks to the postponement, the teams have more time to prepare and we can ensure a fair competition.»

Dr Katharina Simon

Real solutions for real-life challenges

Due to coronavirus, the research accompanying the Solar Decathlon Europe 21 has also been put on hold.

«The SDE21 is not about building just any house, no matter how. It is about finding answers for the city of tomorrow that will actually make a difference. By delaying the competition, we provide the conditions to do just that.»


«We are looking forward to an amazing event in summer 2022 that will be entirely devoted to sustainable housing and living in the city of tomorrow. Now more than ever, we need feasible, innovative solutions for real-life challenges.»


Within the context of Solar Decathlon Europe, 18 teams from eleven countries realize exemplary projects for efficient architecture and energy transformation in urban districts.

Project partners are the Wuppertal Institute for Climate, Environment and Energy, the Utopiastadt gGmbH, the Neue Effizienz GmbH, the WSW Wuppertaler Stadtwerke GmbH and the city Wuppertal.
