Building products play an important role in the sustainability certification of buildings. After all, a large number of the criteria to be considered relate to their quality characteristics. To reduce the complexity of the necessary information, product labels can be helpful as independent proof of quality. With the new 2018 version of its certification system, the German Sustainable Building Council (DGNB) is introducing a procedure for the recognition of such product labels for the first time. For this, label providers must meet a number of requirements. Recognition can be based on three criteria within the DGNB system: responsible resource extraction, the avoidance of harmful and risky substances, and deconstruction and recycling friendliness. The first standards recognised by the DGNB are CSC, FSC, WOOD FROM HERE, Indoor Air Comfort Gold, PEFC and WiN=WiN Fair Stone.
