Is a letter from the manufacturer sufficient to satisfy documentation for the VOC content requirement? They have the VOC emissions evaluation from a certified lab; however, the only documentation for the actual VOC content is through a compliance letter they have signed which states their prodct contains no VOCs. is this enough? The product is a concrete joint filler if that helps. Thanks!

I've never had an issue with using manufacturer statements for the VOC content.

I have the same issue, for using manufacturer statements for the VOC content. Emily, can you explain more, if the manufacturer use self declare for the VOC content, it should complete with detail calculation (if they use calculation method refers to SCAQMD)? or should complete it with detail of test report (if they use lab test) ? Or only statement letter contain with gram/liter of voc content with regulation compliment is enough? thank you for your explanation.

A letter from the manufacturer stating that the product contains no VOCs might not be sufficient on its own for VOC content requirements.Ideally you'll need documentation from a certified lab showing the actual VOC content to meet compliance standards, especially for a product like concrete joint filler.It is best to check with your regulatory body to confirm their specific documentation requirements.

That may be the case for regulatory agencies. I have never had a LEED reviewer ask for a test report or detail calculation for the VOC content portion of this credit. A manufacturer statement, SDS, or product data sheet with the VOC in g/L has always been sufficient in my experience.

Thank a lot for your feedback Emily, just want to make sure is it also applies to LEED version 4.1?

Anna, we work with hundreds of project teams and set them all up for 4.1 for Low Emitting Materials. In our experience, the manufacturer's technical data sheet/product data sheet or SDS with the VOC in g/L is sufficient.
