#26: Aus Hanf und Lehm wird ein System für emissionsfreies Bauen

from Architektur & Bau Forum · host Handwerk + Bau

Mit dem Openly-Modell hat der Schweizer Unternehmer Andy Keel ein Bausystem entwickelt, das CO₂ nicht nur vermeidet, sondern speichert. Ausgangspunkt war das Projekt „Valley Widnau“ – ein Gebäude-Prototyp aus Hanfkalk, Lehm, Holz und rückgebautem Stahl. Im Interview spricht Keel über die Entstehung dieses Systems, über die Rolle von Transparenz, Ausbildung und digitalen Werkzeugen – und über die Hürden auf dem Weg zu einem emissionsfreien Gebäudesektor.
