NC-v4.1 EQc2:Low-Emitting Materials

VOC content evaluation - any real change to Manf documented g/L content reporting requirement?

Hi all,

I've casually heard about LEED review comments insisting upon lab test / third party validation of claimed VOC content (g/L) for wet applied products - that a simple reference on a Manf published data sheet isn't sufficient. I don't see that clearly stated as a v4.1 requirement but could see how the written criteria might be interpreted that way.

Has anyone else experienced review comments of concern related to VOC content documentation validity?

Reviewers are looking for two things: VOC content and General Emissions Evaluation (GEE). The GEE is typically found within the product's Emissivity Data Sheet and includes a description on how the product was tested for VOC content.  Not all products include a GEE at this time.

I am copying and pasting my comments from the GBCI review team for the credit requirements: - The product name on the certificate matches the installed product name listed in the calculator.  - The certification period on the certificate is reasonably consistent with the construction period for the project.  - The TVOC results.  - The modeling scenario (since this is a schools project, the classroom scenario is required).  - A declaration that the product was deemed in compliance with CDPH SM v1.1-2010, or declaration that the product was deemed in compliance with one of the equivalent certifications/programs listed in the v4 Low-emitting Materials Table (https://www.usgbc.org/resources/low-emitting-materials-third-party-certification-table);  - For wet applied products, the amount applied in mass per surface area.

What unit of measure should we be looking for with regards to, "amount applied in mass per surface area"; g/m2?
