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

Hi I’m a little bit confusing, please correct me. On my LEED CS v2009 ceramic tiles, stone and resin will be installed part of the CS scope of works. Could the project get IEQ 4.3 credit, if ceramic tiles will not have FloreScore. All sealants and adhesives will comply with EQc4.1. Thanks in advance. Catharina

Mineral based finish flooring products such as tile, masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated solid wood flooring qualify for credit without any IAQ testing requirements. However, associated site-applied adhesives, grouts, finishes and sealers must be compliant for a mineral-based or unfinished/untreated solid wood flooring system to qualify for credit. Could you clarify what the "resin"?
