Quick answer：Rooftop greening in Germany involves the conversion of roofs into green spaces. This practice includes planting vegetation on roofs to improve insulation, reduce urban heat island effect, and enhance biodiversity. Some notable German rooftop greening cases include the Kombikassenzentrum in Cologne and the Intergastra trade fair center in Stuttgart. These projects often integrate sustainable design principles and demonstrate the benefits of green roofs for urban environments.
