The purpose of the DGNB and the DGNB System is not to provide certification for certification's sake, solely as a marketing tool or to demonstrate leadership; instead, it uses certification as a means by which a consistent overall quality standard can be ensured. Of course this also entails transparent quality control by means of an independent, neutral certification process. The DGNB System is intended to be used both as motivation and as a planning tool, enabling demonstrably better buildings to be built and managed. Sustainability must be approached as an integral part of every building project rather than being an add-on or an optional consideration.
If the DGNB system is to be applied for new buildings, there are certain requirements that must be met.
Unless otherwise specified in the individual criteria, only the building and open spaces directly allocated to it are taken into consideration for the assessment. Some criteria stipulate or allow for the assessment of outdoor areas.
The building will be primarily used in accordance with its scheme.
In addition, the following DGNB minimum requirements apply:
Where individual regulations with regard to minimum requirements exist, these are listed in this document in the section titled "Scheme-specific information".
Current validity of expert reports, analyses and simulations:
Expert reports, analyses and simulations must make reference to the current planning status or the building as it was actually constructed. If expert reports and simulations made reference to a previous planning status, evidence must be provided to clearly demonstrate that they continue to be valid and relevant.
The required documentation must be produced in accordance with the requirements described in the criteria.
Alternatively, the following forms of documentation can be provided:
The requirements of the criterion/indicator remain unchanged.
The criteria specify the required or permissible forms of documentation. The evidence can be provided in another form as long as it clearly demonstrates that the objective of the criterion/indicator has been achieved. Before submitting documentary evidence in an alternative form, the proposed alternative form must be agreed with the DGNB certification body. The decision lies with the DGNB certification body.
If a criterion for an indicator allows for an alternative solution in the form of an innovation area, the indicator in question can be fulfilled by this solution. This enables the objective of a criterion/indicator to be fulfilled by a quality of the building that has previously not been described in this way in the criterion/indicator. Before submitting documentary evidence in an alternative form, the proposed alternative form must be agreed with the DGNB certification body. The decision lies with the DGNB certification body.
Instead of the required documentation, documentation for some criteria can be supplied using a documentation template (can be downloaded from the internal section of the DGNB website). The template must be signed by the people named on the template. By signing the document, the signatories confirm that the requirements listed in the criterion have been fulfilled. The DGNB reserves the right to request individual pieces of documentary evidence on a random basis at a later date as part of the conformity assessment.
