The DGNB System for Biodiversity-Promoting Exterior Spaces helps companies, local authorities and neighbourhood developers to design and maintain areas on built-up properties, façades and roofs in such a way that they support the preservation of biodiversity and ecosystem diversity. In addition, the application of the certification system is intended to minimise investment risks and at the same time ensure greater transparency. The DGNB Certificate for Biodiversity-Promoting Exterior Spaces can be particularly useful for sustainability reporting.
