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.

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? 

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?

NC-v4 EQc2:Low emitting materials

NAF Composites Not CARB

There are particleboard products that are NAF with third party certifications that LEED reviewers will not accept because they do not have a CARB exempt executive order. I have asked reviewers to clarify why this is and only received a reiteration of the requirement. In other categories, there are a variety of emissions testing certifications that will comply. Can anyone explain why a composite product that is made with no formaldehyde and certified as such by a third party that is accepted in other categories would not be acceptable in this one?

Because it is a CARB regulated certification procedure administered by CARB an independent agency would not be acceptable. The testing procedures and documentation is more than simply testing a panel for formaldehyde emissions.

Hi Debra, Collins Pine Particleboard has SCS Global certification for NAF. They are on the TPC list for ULEF MDF but not for their particleboard.

Hi Mike, So you are saying that despite the fact that composite wood has historically been focused specifically on formaldehyde and appears still to be in the category language, in reality there are other emissions involved? If that's the case, it seems like that would be easy for reviewers to clarify. And why isn't a TVOC range required then?
