Circular building is a core theme of the DGNB System. Since the first version of the DGNB System (2008), key aspects such as the responsible use of resources, life-cycle-oriented planning of buildings, ease of deconstruction and recycling, and the avoidance of critical substances have been given high priority in the certification criteria. Particularly advanced circular solutions also have a positive impact on the assessment result through bonus points for the "Circular economy". In addition, reuse, recycling and the non-use of material resources lead to a better assessment of the CO2 and lifecycle assessment of buildings.
With the introduction of the DGNB System for Deconstruction of Buildings in 2020, the sustainable and circular implementation of the deconstruction of buildings or parts of buildings can also be assessed as part of a certification for the first time.
