Whe looks out of the window of the meeting room at Bauder GmbH in Stuttgart from the top floor and sees a monotonous, sober, black flat roof – and colorful grasses that grow at different heights. “There is a trend towards green roofs in cities. The municipalities are also putting pressure on them,” says Tim Bauder, one of the three managing partners of the manufacturer of roof systems. The greening of buildings is no longer a niche topic. The market is growing, and in the course of climate change, green roofs and facades are playing an increasingly important role. It is said that this serves to prevent heat and flooding.
With 4.1 square meters of green roofs per inhabitant, Stuttgart occupies the top position among German cities, as reported by the Federal Green Building Association. More than a third of the cities with more than 50,000 inhabitants promote green roofs and facades. And numerous municipalities indirectly support plants on the roofs by reducing the rainwater fee if a green roof is available.
