Requirements for product labels in the criterion "Local environmental impact"

The objective of the criterion is to reduce or avoid the use of materials, construction products and preparations that can represent a risk to people, flora and fauna due to their pollutant content or the release of harmful substances.

Minimum requirements

The recognition of the minimum requirements for criterion ENV 1.2 is still not currently explicitly required.

Systemic requirements

The fulfilment of systemic requirements is a prerequisite for a recognition of the standard.

Content requirements

In the criterion, requirements for individual construction materials, products and preparations are formulated in a "criteria matrix" in the form of quality levels. If a label fulfils the corresponding requirements, it can be recognised as a standard within the framework of the DGNB certification. This means that the recognised product label can be used as proof for the fulfilment of the respective requirements of the criterion.

As a first step, the label recognition can only be recognised for certain lines, and in this regard only for certain aspects of the criteria matrix of criterion ENV 1.2 "Local environmental impact". For the time being, the recognition exclusively relates to emission characteristics of the following construction products (line of the matrix – emission in question):

  • Textile floor coverings (line 6 – VOC)
  • Elastic floor coverings (line 7 – VOC/SVOC)
  • Auxiliary materials for installation such as primers, precoats, fillers and adhesives under wall and floor coverings (line 8 – VOC)
  • Auxiliary materials for installation such as antiporosity coatings, screed resin, waterproofing under tiles (line 9 – VOC)
  • Sealing compounds, sealants and adhesives for punctiform and linear bonding of components in interiors such as PU adhesive and silane-modified polymers used in skirting boards, door rails, support adhesive (raised or hollow floors) (line 11 – VOC)
  • Adhesive for establishing air-tightness on the inside and outside of façades: e.g. PU, PU Hybrid, MS polymer, SMP or similar, on façades, windows and exterior doors (line 13 – emissions)
  • Seals, 2K PU paints, PU floor coatings (line 20 – VOC)
  • Seals, 2K EP paints, EP floor coatings (line 23 – VOC)
  • Acoustic elements, room-in-room systems, panelling on walls and ceilings, multi-layered parquet, multi-layer laminate surfaces such as chipboards, OSB panels, MDF panels (line 47 – formaldehyde)
  • Bracing wood panels on walls, floors and ceilings in wooden houses or wooden structures such as chipboards, OSB panels etc. (line 48 – formaldehyde)
  • All items of furniture with quality seals that require test chamber inspections of the entire product (line 1 (appendix 2 interiors) – VOC and formaldehyde)
  • Board materials for furniture produced through carpentry, timber products and room acoustics elements (line 2 (appendix 2 interiors) – formaldehyde)

Note: The DGNB will open additional requirements for the DGNB label recognition at a later stage, if necessary. At present, this can take place in a project-specific fashion via proof of equivalence.
