The DGNB System for Buildings is a planning and optimization tool for sustainable buildings. The tool evaluates the environmental, economic, sociocultural / functional, technical and process quality of projects. There are different types of certifications available across the life cycle of buildings: (1) DNGB pre-certification for new constructions, (2) DNGB certificate for new constructions, (3) DNGB certificate for buildings in use (plus a recertification option), (4) DNBG certificate for existing buildings, (5) DNGB certificate for renovated buildings and (6) DNGB certificate for dismantling. Assessments are undertaken by independent, DNGB-trained auditors. DNGB undertakes a final conformity check before the certification is awarded.
