DGNB System for Interiors

How to design demonstrably sustainable, healthy interiors

We spend 90 percent of our time in buildings. Thus, we want to and should feel comfortable in them and be protected from the influences of the environment. Ultimately, the design of interior spaces has a decisive influence on well-being, health and productivity. With the DGNB System for Interiors, the DGNB is closing a gap, as a system has been lacking up to now for projects that only consider part of a building, such as the fit-out of a shop area or an office floor. The system can be used for offices as well as shopping, hotels and gastronomy. Specifically, fit-out projects for offices, bank branches, supermarkets, discount stores or shopping centres can be certified, regardless of whether they are integrated into new or existing, certified or non-certified buildings.

The overall aim of the system is to actively promote people's health, ergonomics, well-being and performance. The more conscious use of financial resources, the careful use of resources, as well as the use of low-emission products are also a further goal. Ultimately, the DGNB System for Interiors is to be understood as a guide to environmentally friendly, health-conscious and more economical interior design, taking into account structural measures such as newly introduced building materials and furnishing of the rooms.

There is currently no DGNB System for Interiors available in English or for international certification. Please contact us for further information and if interested.

The system can be used as a planning tool and is aimed at interior designers, tenants and builders for properties with a high standard of fit-out.

Frequently asked questions about the DGNB System for Interiors

In the first instance contemplation the framework refers to the users influence on the interior development. Are parts of the interior fittings, furnishing or technical equipment not within the client's scope, they might be taken out of the assessment, after consultation with DGNB. It is our main goal to establish this system as a planning tool to improve the interiors, rather than assess an existing condition.

The DGNB Certificate for Interiors will be issued after completion. Because of the usually short planning phases, no pre-certificate is offered. At the time of handing in the documents of proof for conformity assessment at the DGNB, the interior fitting and furnishing should be in place and in an operational phase.

The validity of the certificate for office interiors, gastronomy interiors (pilot phase) and hotel interiors (pilot phase) expires after ten years, for retail interiors after five years. The DGNB System for Interiors is currently only available in German. Please contact us for further information and if interested in a certification.

Conversion or renovation of the interior affects the original evaluation and may lead to the certificate becoming invalid. If the indoor air quality requirements cannot be met, the certificate immediately loses its validity.

To extend the validity of the certificate for another five years, it has to be renewed before the expiration date.

It is possible to obtain the certificate in Silver, Gold or Platinum.
