Das System


National and International

The DGNB Certification System can be applied nationally and internationally.

Public and private

The DGNB Certification System is oriented towards actual practice and can be modified flexibly. Both private investors and building owners on the one hand and city and local authorities on the other hand profit from this flexibility. All of them require reliable principles to economically and efficiently promote and document their sustainability goals.

In-house trainings for authorities
The DGNB is the central knowledge platform in Germany and has comprehensive know-how in this sector. This provides a reliable basis for the responsible authorities to promote their relevant sustainability goals in a targeted way. The DGNB Academy conveys this know-how in in-house trainings focusing on the central topics of sustainable building. Of course, we individually tailor the contents of the events to meet your wishes and needs. And the dates too. And of course our experts come to you. You too can profit from our technical expertise – and have an individual quotation made out for you now. ausbildung@dgnb.de

Urban districts and buildings

Today 13 different building types and – since 2011 – entire urban districts can be certified. 

The DGNB System stands for a holistic viewpoint on sustainable building and is based on two criteria catalogues.

Of course, the scheme for urban districts also reflects the guiding principle of the DGNB and considers the well-proven quality sections. Based on the DGNB philosophy, the quality of life of the residents is regarded as being especially important in the case urban districts: important indicators are, among others, educational facilities, child care, local amenities, and cultural facilities.

As with the DGNB System for buildings, urban districts are awarded pre-certificates and certificates. As urban districts develop in several phases over a long period and the construction phase is considerably longer than is the case for individual buildings, there are three certification stages – the pre-certificate and two other types of certificates. The first of these, with a term of five years, can be awarded when 25 per cent of access and services have been completed. The second has an unlimited duration and is awarded when 75 per cent of the buildings have been completed.

New and existing buildings

With the DGNB System it is possible to assess and certify each building on a set basis in various life phases – new construction and existing buildings. The System thus offers the construction and real estate sectors a maximum amount of transparency and comparability.

A property can be certified as new construction (up to 3 years after completion) or as an existing building (as of the 3rd year after completion).

It is of course possible to certify buildings which have been modernized. Depending on the scope of the modernization measures, the building is certified as new construction with the relevant adjustments or as existing building.

Individual, building ensemble and serial certification

As a rule, buildings are certified individually. If you wish to simultaneously certify several buildings that are equal or very similar, then the DGNB System offers two cost-effective and efficient variants:

DGNB building ensemble certification
This certification option is ideal for buildings of the same construction put up at one location (e.g. residential or office buildings, etc.). Both the DGNB pre-certificate and the DGNB certificate can be awarded. DGNB building ensemble certification can be applied to any existing scheme and any building Advantage: DGNB building ensemble certification has a common documentation. This speeds up processing, reduces the cost and effort required for the documentation and also cuts the certification fees. 

DGNB serial certification
This certification option is ideal for buildings of the same construction put up at different locations (e.g. supermarkets, prefabricated houses, etc.). There is also the possibility to receive the DGNB pre-certificate for the underlying specification. Any existing scheme and any building can be certified. Advantage: Each building that was put up on the basis of this pre-certified specification is given an individual DGNB certificate once the relevant documents have been handed in and checked. The advantages: quality assurance through clear requirements and processes, a common documentation, reduced cost and effort for documentation, greater efficiency and reduced fees.
