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.

Post-construction measurement – formaldehyde / VOC levels exceed limits - KBCN0258

If the measured formaldehyde / VOC concentrations were above the prescribed limits, the appropriate remedial action must be taken, as described in the IAQ Plan. The criterion requires confirmation of 'the measures that have or will be undertaken' however it does not specifically address re-testing. We would expect, however that the IAQ Plan should outline what remedial measures are appropriate depending upon the severity and type of the non-compliance with prescribed limits. Such measures may include re-testing as a matter of 'best practice'. Where levels are found to exceed these limits, the project team confirms the measures that have, or will be undertaken in accordance with the IAQ plan, to reduce the TVOC and formaldehyde levels to within the above limits.

10-Oct-2022 - Title amended to align with standard KBCN naming format for clarity and consistency. Made applicable to International NC V6.

Recognized emission certification schemes – Publicly available databases - KBCN1887

Some of the emission certification schemes recognized within GN22 maintain publicly available databases of products certified against their scheme requirements. These databases can be used to help assessors and project teams identify products that are certified under recognized schemes. Examples include: EU Ecolabel – https://environmental-data.ec.europa.eu/ecolabel/index.html GREENGUARD – https://spot.ul.com/ Indoor Advantage – https://www.scsglobalservices.com/certified-green-products-guide Nordic Swan – https://www.svanen.se/en/search-for-ecolabelled-products-and-services/?sortorder=6&producttype=0&qry=&productgroup= Blue Angel – https://www.blauer-engel.de/en eco-INSTITUT – https://www.eco-institut-label.de/en/ M1 – https://ymparisto.rakennustieto.fi/rakennusmateriaalien-paastoluokitus-etsi-m1-luokiteltuja-tuotteita Indoor Air Comfort® / Indoor Air Comfort Gold® – https://www.eurofins.com/iac-certified   Please be aware that these databases may include products that are certified under a recognized scheme, but which fall outside the product categories, BREEAM performance level, or the approved certification level recognized in GN22. Assessors must, therefore, verify that the certification scheme and product category are recognized within GN22 and applicable to the product being assessed. Please also refer to KBCN0719 - GN22 Recognized schemes for emissions from construction products
