GREENGUARD Gold Certification

GREENGUARD Gold Certification (formerly known as GREENGUARD Children & Schools Certification) offers stricter certification criteria, considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for                                                                                                      use in environments such as schools and healthcare facilities. It is referenced by both The Collaborative for High Performance Schools (CHPS) and the Leadership in Energy and Environmental Design (LEED) Building Rating System.

Chronic Reference Exposure Levels (CRELs)

The exposure to individual volatile organic compounds (VOCs), as detected in the C6 – C16 mass spectrometric analysis screen, has been adjusted to allow no greater than 1/100 of the currently published ACGIH® Threshold Limit Values (TLVs) and no greater than one-half of the California’s Chronic Reference Exposure Levels (CRELs). In many cases, the 1/100 safety factor reduction of TLVs results in the most stringent requirements for an extensive range of VOCs. A total VOC or TVOC maximum allowable limit takes into account the complex mixture of all VOCs found to be emitting from a product, including those with and without TLVs or CRELs.

Emission Controls for Educational and Healthcare Environments

This standard is designed to define low-emitting materials suitable for environments where people, particularly children and sensitive adults, spend extended periods of time, in particular schools and healthcare facilities.
