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?

CI-v4 EQc2:Low emitting materials

Option 2 Budget Calculation - Mechancial Adhesives and Sealants

If pursuing the budget calculation method, how do you capture the layer surface area for mechanical products such as duct sealants, pipe sealants, firestop, etc. that are used in mulitple areas over a small surface area? These products also potentially fall under multiple assembly types, so if there is more than one which is to be chosen?

Hi Gina- I think you've found a loophole! None of the assembly definitions in the Reference Guide include ductwork or piping products, so it seems that if you use Option 2, you may actually exclude things like duct sealant and plastic piping welding solvents from your calculations.  However, if you have firestopping in a wall, for instance, that would be part of a wall assembly and would have to be included. Note that the Insulation System definition excludes ductwork and piping insulation based on addenda from April of this year. Hope this helps!
