Building resource passport
The DGNB’s Building Resource Passport creates transparency about the materials and resources of a building and supports a sustainable circular economy in the construction industry.

The aim of circular construction is to design buildings that conserve resources and are sustainable. The focus here is on reusing existing materials, reducing the use of materials and minimizing the environmental impact.
In order to assess the extent to which buildings contribute to the circular economy, how long they can be used and adapted and whether they can be dismantled, separated and recycled in the future, a sound basis of information is required. The DGNB’s Building Resource Passport provides precisely this basis. It serves as a documentation tool for all life cycle phases of a building and ensures transparency with regard to the materials used, greenhouse gas emissions and the reusability of resources.
It is also compatible with existing digital tools. The passport is designed as a documentation template and is not recognized in a standardized way. However, its use is recommended for the DGNB certification of new buildings according to the 2023 version, as it facilitates the disclosure of data and simplifies the assessment process.
We offer:
- Personal and individual advice on the subject of the building resource passport
- Advice on recyclability: recommendations on reusability and sustainable material selection, including the use of tools such as the Building Material Scout for material evaluation
- Optimization of construction and renovation concepts: support in planning resource-saving measures
- Integration into certification systems: Support for DGNB certifications
Concept and objectives
The principle of the building resource passport is based on the established energy certificate. Relevant information on resource use, climate impact and recyclability is recorded for each building. This data is crucial for creating urban mines, implementing circular refurbishments and new buildings and enabling sustainable and selective demolition.
In the long term, the passport forms the basis for a functioning circular economy in the construction industry. All life cycle phases, from planning to reuse, are optimally coordinated. Complete transparency about the materials used, their values and ownership is essential. This enables new business models and ensures the quality of the built environment.
In addition, the building resource passport can serve as the basis for an aggregated circularity assessment of a building.
Advantages for various stakeholders
The building resource passport provides owners of new and existing buildings with a detailed overview of the materials used and potential pollutants. It also shows which valuable resources are contained in the building.
For planners, the passport offers valuable insights, especially if additional detailed sheets are maintained. These can support in-depth analyses and sound advice for building owners, as well as highlighting resource-saving and recyclable options.
