In order to make sustainable construction plannable, assessable and measurable, the DGNB has developed a certification system which, as a planning and optimisation tool, helps all those involved in construction to implement a holistic quality of sustainability. In order to be able to evaluate sustainable construction, various certification criteria are applied individually to different types of buildings.
Every building, from planning to demolition, goes through different phases, which are linked to different requirements and conditions. These can be accompanied by the DGNB certification system in terms of a holistic sustainable construction method. The following diagram shows exactly which phases these are.
DGNB certification can be applied to both new and existing buildings as well as to renovation and buildings in use.
