We have project using an epoxy terrazzo poured floor where the VOC's for both components are 0 g/L. I understand that these would be listed in IEQc4.2 under floor coatings. My question is that a LEED reviewer has just recently denied IEQc4.3 on another project because we were under the impression that terrazzo was exempt, but they are saying that the epoxy terrazzo is not entirely mineral-based and that it must comply with the credit. So does that mean that it has to be FloorScore or comply with CA 01350 testing? There doesn't seem to be any clear direction as to whether a poured epoxy floor needs to comply with both IEQc4.2 and 4.3, or should it really just be under IEQc4.2.

Nena, I would agree with the reviewer in putting a terrazzo floor under scrutiny. We have been concerned about the epoxy in these floors. My opinion, the terrazzo itself can be confined to just IEQc4.3 and not both credits. If there is a coating on top of it, that would also be IEQc4.2.Let us know if you got further clarity on this!

I had a similar poured floor that I was trying to specify correctly so I posed a question to Kristen Vachon Vogel, Certification Reviewer, at the GBCI Certification Work Zone at Greenbuild in DC. Sorry for my belated post. The manufacturer that I was working with noted the numerous components as an Industrial Maintenance Coatings. Kristen indicated that I should pick "Other" on the IEQc4.2 form and input the components under that heading.
She followed up with this via e-mail, which was enlightening: "All products listed in SCAQMD Rule 1113 which are used inside the building weather-proofing system must be reported in the LEED IEQc4.2 credit form, not just the products included in the Table published in the addenda. The table only includes a list of commonly used products. A form fix has been requested of USGBC, to include all applicable products in the standard."
It'd be swell if they fixed the form.
