Especially in 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 retail spaces, office space or flats are often found above. The respective special features must be taken into account in sustainable planning within the framework of a holistic sustainable approach. The scheme for mixed use can be used as a planning and optimisation tool.
Projects can be registered in the current market versions "New Construction of Buildings, Version 2018" as well as "New Construction of Buildings, Version 2023" and "Buildings In Use, Version 2020". For international projects "New Construction of Buildings, Version 2020 International" and "Renovation of Buildings, Version 2022 International" are applied.

In the scheme for newly constructed mixed-use buildings, the DGNB evaluates different uses very specifically according to the corresponding needs. This ensures a fair and comprehensible assessment. The scheme with the largest share of space determines the largest share of the assessment and is referred to as the primary use. Uses with a floor area share of the total DGNB assessment area ≥ 15 percent (secondary use) are additionally assessed with the corresponding scheme. Secondary uses < 10 percent of the DGNB assessment area (Version 2018) or < 200 square metres /400 square metres (for the MIX15 version < 15 percent) can be neglected. The application rules or system principles must be followed.
If a proper distinction can be made between the different uses, an application for partial certification can be submitted. The use that is to be assessed must be clearly defined and must be agreed with the DGNB on a case-by-case basis (project-specific certifiability enquiry – see DGNB website). The following parameters should be complied with:
- Separate energy performance certificates must exist for the different sub-areas
- Separate entrances to the building must exist
- Different uses can be identified, e.g. from the façade design
- Technical building equipment in the different sub-areas functions independently of each other
Overview of all
criteria and schemes
In order to address the individual characteristics of your building project, the DGNB System takes into account a variety of criteria and schemes.
You can find an overview here.
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.
The current DGNB Systems "New Construction of Buildings, Version 2018" and "Buildings In Use, Version 2020" apply. The current DGNB Systems "New Construction of Building, Version 2020 International" and "Renovation of Buildings, Version 2022 International" apply to international projects.
