FAQs about EQc2 :

Is all solid wood considered inherently non-emitting? I’ve seen sources that say only solid wood flooring counts as inherently non-emitting.

Are throw rugs subject to the credit requirements?

If a ceramic tile receives a top coat after it is manufactured, is it exempt from the credit requirements?

What are the adhesives and sealants to be included in the documentation?

I'm looking for a certification that tells me if a given product will meet the LEED v4 requirements, but I don't see one in a given product area. Am I missing something?

When products claim that they meet California Section 01350, does the product also meet LEED v4 requirements for low-emitting materials?

How do I know if a product complies with LEED v4 or if it was tested under an older non-compliant standard?

In past versions of LEED, it was easy to specify VOC limits. Is the specification process the same for LEED v4?

Is there a VOC budget method for this credit?

What are the limits on the VOC budget method?

Do products applied to the weather barrier need to comply with VOC thresholds? 

If one part of my multicomponent wall system is not compliant, can I still get full credit?

Our building is atypical, and the walls and ceilings are not clearly defined. How should we classify these components?

NC-v4 EQc2:Low emitting materials

General Emissions Evaluation - Grout & Tile Setting Materials

A question regarding sanded grout and fast set for ceramic tile. Our manufacturer is telling me that they do not need to be tested since they are cementitious chemistry and do not emit anything per CDPH Standard testing. Is this statement correct to comply with EQc2? Looking for confirmation on whether this situation falls into the Adhesives / Sealants applied on-site.

Grout is not mentioned in SCAQMD Rule 1168, so the only reasonable VOC limit one can use is 250 g/L for "Other." If they can provide a letter stating that since they're cementitous they don't have to test to meet CDPH, that would be helpful.  It's unclear why grouts are included in this credit since they are cementitious, and I've commented on this rating system asking that it be removed, but to no avail.

I believe additives can be used for workability. ie. Laticrete's 333 super flexible latex additive for use with Laticrete 317 thin set (tile mortar.) And the 333 product does have VOC's.  Rule 1168 has a VOC limit for ceramic tile adhesive which means anything used like a thin set mortar to install ceramic or glass tiles.
