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

Unfinished Engineered Hardwood

Hello, It's stated in IEQc4.3 that unfinished/untreated solid hardwood automatically qualifies for this credit. Could the same be said for unfinished engineered hardwood? This would be a engineered product that meets the requirements of 4.4 (composite). It would be finished on site with a finish/stain meeting the requirements of 4.2 Thanks!

Becky, the LEED Interpretation that established the language you're referring to specifically refers to "solid" untreated wood flooring. I do not think this would apply to a composite product, even meeting IEQc4.4 requirements.

Engineered hardwoods generally do not use urea-formaldehyde binders/adhesives, which is what usually causes issues with compliance for EQc4.4.

Hi Becky, I agree with Tristan. I've had this situation with an engineered wood flooring product. It is subject to the FloorScore requirement.
