Which organization’s standards are referenced for testing VOCs in indoor environments?

The California Department of Public Health (CDPH) has established standards for testing volatile organic compounds (VOCs) in indoor environments, making it the correct choice in this context. The CDPH's standard method for testing VOCs, particularly in building materials and indoor air, is often referenced in LEED assessments to ensure compliance with low-emission requirements.

The CDPH method provides a rigorous framework for assessing indoor air quality by measuring VOC emissions from building products, which is a crucial aspect of creating healthier indoor environments. This emphasis on VOC testing supports LEED's goal of promoting better indoor air quality, thus benefiting occupant health and productivity.

While other organizations, such as ASHRAE and the EPA, have their own standards related to air quality and building performance, the specific methodologies for testing VOCs in the context of indoor environments are most commonly aligned with the standards set forth by the California Department of Public Health. ISO also offers various standards related to air quality, but they are generally broader and not solely focused on VOC testing in indoor settings.
