What is the IAQ Credit point range for selecting different categories of low-emitting materials?

The point range for selecting different categories of low-emitting materials under the Indoor Air Quality (IAQ) credit reflects the flexibility provided within the LEED BD+C V4 standards. Specifically, the credit awards one point for meeting the requirements for low-emitting materials in any one category, such as adhesives and sealants, paints and coatings, flooring, and so forth. If a project achieves compliance across multiple categories, it can earn additional points, leading up to a maximum of three points in total.

This structure encourages project teams to not only address one aspect of low-emitting materials but to adopt a more comprehensive approach that improves overall indoor air quality. The credit aims to minimize the impacts of volatile organic compounds (VOCs) and other harmful chemicals on building occupants, thereby enhancing health and well-being. This comprehensive approach is reflected in the point range for the credit, distinguishing it from other credits that might have more limited scope or fewer points available.
