The DGNB Building Resource Passport:

The DGNB Building Resource Passport:
Comprehensive documentation for the entire life cycle of a building

The concept of circular construction aims to design buildings that conserve resources and are sustainable. The focus here is on reusing existing materials, reducing the use of materials and minimizing environmental impact. Reliable information is required to assess the extent to which buildings contribute to a functioning circular economy, how long they can be used and adapted and whether it is possible to dismantle, separate and recycle the materials at a later date.

The DGNB’s Building Resource Passport provides precisely this data basis. It serves as a central documentation tool across all life cycle phases of a building and creates transparency with regard to the materials used, the associated greenhouse gas emissions and the recyclability of resources. It is also compatible with common digital tools. The passport is intended as a template for documentation, but is not recognized as standardized. Nevertheless, its use is particularly recommended for DGNB certification for new buildings according to the 2023 version, as it facilitates data disclosure and makes the assessment process more efficient.

Concept and objectives

The basic idea of the building resource passport is based on the familiar energy certificate. Relevant information on resource use, carbon footprint and recyclability is recorded for each building. This data forms the basis for the development of urban raw material stores, circular refurbishment and new construction projects as well as sustainable demolition.

In the long term, the passport will help to establish a functioning circular economy in the construction industry. It enables optimal coordination of all life cycle phases – from planning and use through to recycling. Complete transparency about the materials used, their value and ownership plays a central role in this. This opens up new economic opportunities and supports sustainable construction methods.

In addition, the building resource passport can be used to create a comprehensive circularity assessment of a building.

Advantages for various stakeholders

Both owners of new and existing buildings benefit from a detailed overview of the materials used and the potentially harmful substances they contain. The passport also provides information about valuable resources that are present in a building.

For planners, the document provides a valuable data basis, especially if additional detailed sheets are added. These enable more in-depth analyses, sound advice for building owners and the identification of resource-saving, recyclable construction methods.
