FAQs about IEQc4.3 :

On a renovation, should flooring that is previously installed be subject to the credit requirements?

One flooring adhesive we are using falls under both IEQc4.1 and IEQc4.3, and is over the VOC limit. We are using the VOC budget method to meet IEQc4.1 requirements, but are we automatically disqualifed from IEQc4.3?

The credit requirements are allowed to exempt unfinished wood flooring from the credit requirements, but wood flooring is almost always finished. This is confusing!

I have an international project and my flooring products aren’t tested using any of the above standards. How can I tell if they still comply?

If I have no flooring products in the scope of my project, can I earn this credit?

How do I handle a polished concrete floor?

Should mineral-based finish flooring products (without any integral organic-based coatings and sealants) and unfinished/untreated solid wood flooring be documented on the IEQc4.3 LEED Online form, even though they are exempt from certification requirement

NC-2009 IEQc4.3:Low-Emitting Materials—Flooring Systems

flooring systems

Im confused, im not attempting IEQ Low-Emitting Materials-Adhesives and Sealants but i am attempting IEQ Flooring Systems. In this case, eventhough I am not attempting IEQ 4.1 in Flooring systems template there is a table of Flooring Adhesives and Sealants. Do I have to fill out the table and specify my VOC? Or if im not going for adhesives and sealants credit i just have to leave it unfilled . Thank you very much!

Kash - the flooring credit (EQc4.3) mentions using low-emitting adhesives because most flooring needs some adhesive to stay down. Using low-emitting adhesives would be best for the indoor air quality, regardless of getting EQc4.1, but if you aren't going for the adhesives & sealants credits your flooring adhesive does not need to meet the criteria.

Josh, just to be sure, has the USGBC already accepted this kind of justification path for a project ? The point is we are NOT getting C4.1, but still we have tile sealants/grouts that would fall under C4.3. and i don't feel comfortable not to submit emissions for these products.

If the sealants/grouts pass the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda, then the grouts will be fine.
