There are a number of certification systems for sustainable building. The DGNB System is unique. It provides an objective description and assessment of the sustainability of buildings and urban districts. Quality is assessed comprehensively over the entire life cycle of the building. The DGNB Certification System can be applied internationally.
Due to its flexibility it can be tailored precisely to various uses of a building and even to meet country-specific requirements. The outstanding fulfilment of up to 50 sustainability criteria from the quality sections ecology, economy, socio-cultural aspects, technology, process work flows and site are certified. The system is based on voluntarily outperforming the concepts that are common or usual today.
If a performance requirement is met, the DGNB awards the DGNB certificate in bronze, silver, gold. In addition, there is the option of simple pre-certification in the planning phase.
