What lends contemporary architecture a futuristic character are glass facades. A challenge Nabo Gass has been working on for almost 20 years. For his ideas of facade design in conjunction with photovoltaics, he received the Innovation Award of glasstec in Düsseldorf. The first project was realized in the Münsterland region in 2012. According to his design, the first high-bay warehouse with a solar facade was built. The glass architecture, combined with sophisticated solar technology, was so convincing that the Sustainable Building Council (DGNB) certified the building with gold. Of particular note, the building has also won two major architectural awards.
The glass facade of the IGM building in downtown Hannover is dedicated to trade unionist Otto Brenner. One of his central messages has been immortalized by Nabo in various languages in the glass facade: “Not peace, not subservience to the authorities is the first civic duty, but criticism and constant democratic vigilance.”
