Revisions and updates to the DGNB System for Buildings In Use

The new version of the system is a revision and update of the existing DGNB System for Buildings In Use, Version 2020. The aim of this revision is to ensure both current reporting requirements in the property sector and evolving regulatory factors are incorporated into the new version and thus make properties fit for the future.

The new focus of assessments

In addition to tightening a number of requirements, adjustments have been made to how points are distributed within the individual criteria. As a result, greater emphasis is now placed on evaluating actual building performance. Also, more emphasis is now placed on energy efficiency, complementing the existing focus on greenhouse gas emissions. In addition, the characteristics and qualities of existing buildings are now more strongly integrated into assessments.

A completely new focus has been placed on indicators relating to biodiversity. Whereas the previous 2020 version of the DGNB System for Buildings In Use included this topic under the Procurement and Operations criterion, the revised version introduces a dedicated criterion called 'Biodiversity and Rainwater Management' within the Environmental Quality section. This aims to promote biodiversity and strengthen on-site natural water cycles. However, the DGNB reserves the right to integrate this topic into existing criteria in the final published version, provided it maintains the same level of importance.

Compatibility and international relevance

The review process has also focused on compatibility with other rating systems. For example, the update aligns with the requirements of the EU taxonomy. ESG assessments offered by the DGNB can continue to be carried out both alongside and independently of Buildings In Use certification. In addition, standards underlying other reporting and assessment initiatives have been used for guidance purposes in developing requirements. These include the Corporate Sustainability Reporting Directive (CSRD), the Sustainable Finance Disclosure Regulation (SFDR), the Global Real Estate Sustainability Benchmark (GRESB), the Energy Performance of Buildings Directive (EPBD), the Carbon Risk Real Estate Monitor (CRREM) and management systems in accordance with ISO 14001 (environmental management) and ISO 50001 (energy management). Information on this can be found in the description of the methods used for the criteria.

By aligning with international standards, the new version of the system can be used throughout Europe. Deviations in methods or validation were made only in exceptional cases to accommodate the requirements of specific countries.

Note: Some sections in the draft version of the criteria set are highlighted in yellow. These were still being worked on when feedback started and are not part of the commentary process. Before publishing the final revision, the DGNB will also define minimum requirements for some criteria. These are also not yet part of the draft version.
