LEED v4 low VOC - Systems Approach
VOC emissions limits are not calculated for single products, e.g. an adhesive, but for all products going into a surface, e.g. a floor or a wall ("systems approach"):
- Each product is evaluated separately, not the whole system.
- Percentage of conformity then is calculated per system.
- Total number of assigned points depends on the total percentage of surfaces covered by low emitting products.
The systems are defined as:
- Thermal and Acoustic Insulation
- Healthcare and Schools projects only:
- Exterior Applied Products.
Between one and three points can be earned if the specifications on low VOC are fulfilled partly or completely. For details please see the credit documents
US GBC operates a list of common low VOC rating systems that allow showing product compliance. Some of them are directly compliant, such as the Indoor Air Comfort GOLD program; other ones are compliant only if the test report shows low formaldehyde emissions of max. 10 µg/m³ after 28 days the reference room, in line with the French A+ class. The French A+ class alone is sufficient only for Composite Wood products, not in general. The list of compliant rating systems can be seen on the US GBC website.

Eurofins VOC related services
Eurofins offers documentation of compliance with the specifications on emissions of VOC and aldehydes by independent and ISO 17025 accredited testing, and if relevant also with external surveillance (inspections, re-testing), and certification, e.g. in combination with the Eurofins operated certification programme Indoor Air Comfort - certified products.
Eurofins operates both an accredited and notified test house and an approved ÜZ certification body. VOC emissions testing for any program or regulation can be easily combined with tests for other regulations or labels such as Belgian VOC regulation, French VOC regulations, German VOC regulations, EMICODE, German Blue Angel, Finnish M1 and US tests. Such combinations allow to save money compared with separate testing for each of these purposes. One example is the Eurofins Pan-European test package.
Certification and testing services for Ü mark, CE mark and the Eurofins certification program Indoor Air Comfort - certified products can be ordered in parallel for use on different market segments - there will be significant costs saving when compared to ordering these services separately.
