Ich war Dr. Zelt. Frei Otto über Anpassungsfähigkeit, Ökologie und Ökonomie im Bauen / I Was Dr. Tent. Frei Otto on Adaptability, Ecology, and Economy in Architecture

Von Otto, Frei /  Escher, Cornelia /  Förster, Kim

In our interview, we would like to focus on two central issues: adaptable and ecological architecture. As early as the post-war years, you were developing techniques that incorporated the reuse of materials, representing something of a foundation for both of those fields.

You must be referring to one of my earliest publications about backing masonry. That must have been the late 1940s.

In the 1950s, you published other articles, such as "Das ungeheizt schon warme Haus" [The unheated, yet warm home], which explores the question of energy conservation through solar energy.

I could demonstrate the principle using the example of the studio that we’re sitting in right now. If the sun began to shine, it would be warm in here in ten minutes without any additional heating. That’s a so-called passive house. That’s not as interesting today as it once was, because the active use of solar energy has made such progress. I investigated the issue of passive solar housing in my Diplomarbeit [graduate thesis] in 1952, with a design for such a housing estate in the Berlin neighborhood Waidmannslust.
