Frequently Asked Questions

Why is SUM focussing on tenement flats?

SUM tackles the alarming state of Dutch post-war neighbourhoods by creating a solution for tenement flats across the Netherlands and beyond. In the Netherlands, there are 847,00 tenement flats, which represent 11% of the total housing stock. Tackling this type of building creates the opportunity to contribute to Dutch nationwide goals of being energy-neutral in 2050 and adding one million homes by 2030.

With our tenement flat repurposing strategy we would like to make a world where diversity, innovation and social interaction are stimulated. Where clever design solutions can tackle social, economic and environmental challenges. SUM creates a symbiotic breeding ground that leads to affordable, living communities, and a sustainable environment.

What is the Solar Decathlon Europe Competition about?

Initiated in 2002 by the United States Department of Energy, the Solar Decathlon (SD) is a university-level student competition for resource-responsible and energy-efficient architecture and engineering in the building sector. The competition challenges universities from all over the world to design, build and operate a solar-powered and energetically self-sufficient home equipped with advanced technologies, and designed to the highest standards of sustainability.

I want to visit the pavilion. How can I visit and when?

Come and experience first-hand what climate-friendly building and living in the future can look like. The opening days of our prototype are 10 to 12 June, 16 to 19 June and 22 to 26 June 2022.

We're located at the Solar Campus in Wuppertal. The main entrance is on Nordbahntrasse, north of the “Mirker Bahnhof” (Mirker Str. 48).
