The DGNB Certification System was established in 2008. Its aim is the planning and assessment of sustainable buildings. In order to ensure the maximum possible amount of quality and transparency, around 40 criteria from the quality sections environmental, economic, sociocultural and functional aspects, technology, processes and site are incorporated into the assessment. If these are fulfilled excellently, the DGNB Certificate is awarded in platinum, gold or silver. Certification follows a holistic approach: the DGNB System assesses the entire life cycle of the building. This makes it possible to define sustainability goals right at the start in the planning phase. Based on these goals, high-quality buildings that are well set up for the future can be produced. The DGNB Certificate is a valuable and meaningful quality seal for the real-estate and construction sectors. To date more than 850 projects have been certified or registered for certification by the DGNB.
