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?

Are Limestone and Marmoglass considered as hard flooring system, and thus, has to be FloorScore certified fo IEAc4.3? I could not find any supplier for Limestone and Marmoglass with FloorScore certification.

Mineral based flooring products such as yours are exempt. see also LEED reference guide addendum 4/14/2010 You just have to make sure your adhesives, grout, coatings and such are compliant with the maximum VOC limits.

Also remember that FloorScore is not the only way to show that a flooring product helps achieve the credit - the product simply has to show that it passes the California Department of Health Services CA 01350 requirements.

I agree with Susann. Thanks.
