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

VOC requirements for industrial floor

Hello,

I have question concerning flooring materials requirements.

In our project we have industrial floor, which consists of (counting from ground level): polyethylene film, extruded polystyrene, wire mesh + concrete (class C30/37), floor hardener. Since general emission evaluation requirements are relevant for interior materials within waterproofing membrane, I would classify the concrete C30/37 the layer of waterproofing membrane. My assumption comes from the European standard EN 206-1 definition of C30/37 concrete  which defines it as waterproofing. Please let me know if my line of thinking is correct.

Thank you in advance for your answer.

Hi Agata, It would be safer to define the polyethylene film as the water-proofing membrane, because water does tend to wick through concrete. I don't understand why it matters either way, however, as concrete is defined in the credit as "inherently non-emitting", so it's not subject to any reporting/testing requirements. So your documentation would be the same in either case.
