Does this ever happen in North America?
While in North America the average size of Green Roof is around 8,000sf this size would be considered a small size Green Roof in Germany. The average size in Germany is likely over 25,000 sf and the amount of Green Roofs build every year is probably 10 times higher.
Despite higher energy costs, the costs for the installation are lower in Germany because they build them in less than the half time, with fewer people, with hardly any middle men, without pre-planted plastic boxes and without consistently reinventing the wheel. They don’t try to sell warranties – they are actually installing Green Roofs. They also spend no or less time posting their projects on all social platforms and don’t need to say this is the biggest, nicest, most divers, highest or any other superlatives.
They just do it because they understood the environmental and social benefits of Green Roof mass production instead of trying to grow one carrot in a city for millions of people just to be on TV. Green Roofs in Germany are done for everybody vs. in North America it is often done for personal vanity.
