The DGNB system is a comprehensive approach that focuses on the building lifecycle to assess the sustainability of buildings and urban areas.

It includes many different variations and can be applied to new construction, renovation, demolition, existing buildings, interior design, and construction sites. Depending on the type and stage of the project, the DGNB system can be used as a planning, optimization, or management support tool to support decision-making and ensure the implementation of high-quality standards.
