What if the world’s most sustainable steel curtain wall system (Jansen Viss) were combined with the world’s most lightweight steel construction system (Skellet)? That is exactly what Jansen by ODS has done, offering a gigantic CO2 reduction and wide choice of lightweight construction types. Jansen by ODS not only decided to move towards circularity, but they developed an integral service in collaboration with multiple market players on top of that. They have become experts at connecting the dots, i.e. how a Steel Façade Community deals with reversible design, because construction waste is a design flaw.
