Emissions from construction products – Re-used and reclaimed products - KBCN1869

The Emissions from construction products criteria in BREEAM are intended to apply to newly manufactured construction products and materials. Where a construction product can be robustly identified as previously used and is re-used or reclaimed, it may be considered as outside the scope of the Emissions from construction products criteria. However, any new coatings, finishes, adhesives, sealants, or other chemical treatments applied for the product’s installation must be considered and assessed separately, where relevant.

Emissions from products – Recognition of carcinogen classifications from non-EU schemes - KBCN1879

Where BREEAM material emission criteria reference Category 1A and Category 1B carcinogens, these classifications are based on the EU CLP Regulation. However, where a certification scheme or testing body does not work directly to EU CLP classifications, other recognised authoritative carcinogen classification systems may be accepted as an alternative basis for carcinogen identification. This can include: • International Agency for Research on Cancer (IARC) • California Office of Environmental Health Hazard Assessment (OEHHA)

Formaldehyde E1 emissions requirements – Untreated solid wood - KBCN1881

Testing for formaldehyde is not required for untreated solid wood where no formaldehyde containing binders, resins, adhesives, coatings, or chemical treatments have been used in the processing or manufacture. In such cases, a formaldehyde emissions test report is not required. However, the assessor must obtain confirmation from the manufacturer/supplier that:

• the product is solid, untreated timber
• no formaldehyde has been used as described above

VOC credit issues – Clarification of scope - KBCN1797

The scope of these requirements does not include furnishings or moveable furniture, e.g. desks, seats or shelving. It includes fixtures and fittings that are integral to the building, such as kitchen units and toilet cubicles. However, bespoke fixtures, such as purpose-made items of fixed furniture, can be excluded, as the specified compliance testing is not appropriate for such items.
