FAQs about IEQc4.1:
Do products applied to the weather barrier need to comply with VOC thresholds?
How do I determine what application my product falls under?
How is VOC % less water determined for aerosol adhesives?
Do grout and caulking need to be included, and if so, what is the application category?

SMACNA (SHEET METAL AND AIR CONDITIONING CONTRACTORS' NATIONAL ASSOCIATION, INC.) released the following (see link below) Technical Resources Bulletin stating that: "In response to the following Credit Interpretation Request (CIR): “How does a project
team classify duct sealants for application under EQc4.1?” the USGBC issued the
following ruling: “Project teams may classify duct sealants under “Other”, as listed in the SCAQMD VOC Limits table.”
The category of “Other” in the SCAQMD VOC Limits table has a maximum limit of 420 g/l. This should allow most if not all duct sealants to be utilized on LEED®"
