Especially in the city centres, buildings with only one use are relatively rare; often the individual floors are used for different purposes. While the lower floors are usually occupied by retail space or restaurants, the upper floors are often occupied by offices or flats. A mixture of different uses is also increasingly found on shared areas within a floor, as is the case with retail gastronomy, for example. Anyone who wants to plan, implement and certify mixed use spaces under the aspects of sustainability can use the DGNB System for Interiors. The different uses of the spaces are considered individually and taken into account proportionally in the certification.
For mixed use interiors, there is currently no DGNB System available in English or for international certification. Please contact us for further information and if interested.
- Promoting healthy and pleasant indoor spaces across all uses
- Improving communication through design concepts

The certificate is aimed at all organisations that want to plan, implement and set up a fit-out for different uses in a new or existing building. These can be tenants, investors or building owners. For those who spend a lot of time indoors, the DGNB Certificate serves as independently verified proof of the holistic sustainability quality of the interior.
- Differentiation from competitors
- Image gain and employee loyalty
- Planning security and clear definition of goals from the outset
- Value-retaining fit-out
- Detailed documentation of materials, furniture and technology used
- Contribution to CSR activities
- Quality-assuring processes up to the handover of the keys and beyond
The DGNB assesses different uses very specifically according to the corresponding needs. For this reason, interior spaces with different uses are assessed with a mixed use. Office space is assessed with the requirements for office space, retail space with the specific requirements for shops, and so on. This ensures a fair and comprehensible assessment.
In the case of mixed use, a primary use is always determined first. Classically, this refers to the largest share of space to be certified. The criteria of this scheme comprise the basis for further adjustments. In the case of strongly differing, individual criteria, the evaluation is weighted by area according to the different uses and combined again into an overall evaluation. Subordinate areas < 15 percent of the DGNB assessment area can be neglected.
The validity of the certificate depends on the primary use.
Mixed uses can be certified with the DGNB System if the intended schemes are available in the market version. Currently, this applies to the schemes office and shopping interiors. Hotels and gastronomy can only be mapped via mixed use after the end of the pilot phase and with the introduction of the market version.
Project registration
To register a project, clients must first hire a DGNB Auditor. This auditor can then register the project. Auditors also accompany the entire process and take over the verification and submission to the DGNB. They are active worldwide and specialise in certain schemes.
For mixed use interiors, there is currently no DGNB System available in English or for international certification. Please contact us for further information and if interested.
