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?

The credit language mentions that "all flooring materials" should comply with this credit requirements. Since the intent of this credit is about the effect of indoor air quality on occupants, I have the following queries: 1. The LEED boundary of my project includes the lobby and restrooms located in the building core. Since these areas are "non-regularly occupied spaces", do the flooring materials used in these areas need to comply with this credit requirements? 2. The lobby area has natural stone flooring and the entire restroom area has ceramic tiles. In the case of having to comply, is it correct that ceramic tiles qualify without certification? Additionally, I would like to know if the cement grout used for laying the ceramic tiles (restrooms) need to comply with VOC requirements?

Hi Tanmay, All flooring materials in your project need to be included, not just regularly occupied spaces with flooring. The tiles comply without testing or certification. Grouts have been discussed a lot in this forum. I would look for low-VOC options despite the fact that it is not necessary (in my opinion) to include grout. Lauren
