FAQs about IEQc4.3 :

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

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?

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

Aluminum Flooring

Okay so what about aluminum flooring? It's not a mineral. So it doesn't appear to be explicitly excluded. Yet, there are no binders or resins to be concerned about. Is this type of flooring subject to the requirement?

I would submit it as exempt, but include an exlanatory note. It seems like it should be exempt but no one thought to put "uncoated metals" in the addendum.

Well, the small hitch is that it does have a coating - aluminum oxide. Though I see that coating is possible on wood flooring, it does not appear to be an "organic based integral coating". So I'm still thinking exempt. Would you concur?

Aluminum oxide coatings, I believe, need a carrier of water or solvent. Seems like we have a potential emitter of VOCs. I'd include it.

A project I'm working on has stainless steel skirting. As skirting is considered a flooring product, it would appear that this needs to be included in the documentation. My understanding is that stainless steel generally does not have a coating and thus should qualify for an exemption. Is that correct?

Michael, I would check with the supplier or manufacturer. It's not uncommon for stainless steel to have a coating for easier maintenance, as it can be an absorptive surface. Just Google "coated stainless steel" if you don't believe me.

How is it relevant to include a coating of a product that is applied during the manufacturing process? Isn't this credit's intent to understand the offgassing that occurs up to 72 hours after it is applied within the building envelope? Which off-gasing would occur in an entirely different facility and arguably a controlled area? This is grasping at straws for a sealant to be on pre-manufactured materials in a calculator.
