Systematic planning. The DGNB certificate in practice.
To make sure that the DGNB certificate provides a lot of information, we specified clear principles and structures that are identical for the assessment of all schemes. A catalogue of some 60 criteria serves as the basis. The criteria are weighted in accordance to their importance for the particular scheme and used to design an assessment matrix.
The criteria in the DGNB‘s core system define sustainable building in six fields. The site quality does not play a role in the assessment of the total performance index.
