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?

Is Reused Wood Flooring Required to be Certified?

Is reclaimed wood flooring required to be certified? Similar to EAc1.4 and MRc7, I would assume reused products would be exempt but I have not found a reference for this. Assuming our finishes meet the requirements I would think that the project would meet the requirements. Has anyone had this experience?

Hi Nina, I haven't had experience with this but I agree with your hunch that as long as your finishes/sealants meet the requirements, using a reclaimed wood is fine. I think the concern with wood is specifically with products that are engineered or treated. Hope that helps.

Hi Nina, Yes, from my experience, reused wood flooring would be excluded. However, if there were any floor coatings, sealants, adhesives, etc. applied to the wood flooring on-site, those items would need to comply with the EQc4 requirements. Lauren

Laure, Kate, Would you know if I could make the same assumption for reused carpet? We are reusing all the exisiting carpet and the new sealants meet the VOC requirements. Assuming that the new carpet specified complies, could I achieve the credit IEQ 4.3? Also, what would happen in the case that no new carpet is specified, would we get the credit by default or would we not get any credit? Thank you very much in advance for your help! Alicia

Alicia, Reused carpet would also be excluded but you cannot get the credit by default if you have no new carpet. The credit is for all flooring systems, so as long as you have a flooring system that is installed (and not re-used) and it complies with the credit's requirements then that would be enough. For instance, if you had vinyl flooring that was FloorScore certified. However, if all of your flooring systems are reused materials then I do not think you could get the point. Lauren
