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?

LEED Compliant Epoxy Floor Coating?

I see this topic somewhat proposed, but I haven't been able to really see an answer. Our situation is such that all our floors are complying with the requirements of EQc4.3, except a couple janitorial closets where we would like to use an epoxy concrete floor coating. We are considering this coating a ‘high-performance’ or as defined by SACQMD Rule 1113, a ‘Industrial Maintenance Coating’. Do you think this is the right classification, meaning we have a 100 g/L limit, or should it be considered it something else? Does anyone else have experience with a high performance floor coating and meeting compliance with LEED 2009?

Rebekah, I have actually worked on a project where we lost this credit because of an epoxy spec requirement. It was a veterinary space and we had to use this epoxy flooring throughout our project. One thing that I do not think has been officially determined by LEED is whether or not you can do a VOC budget for your EQc4.1 referenced coatings/sealants, etc. listed under EQc4.3. My feeling is that you had one coating that was not in compliance for EQc4.3 you might be able to reference how you comply, overall, through a budget in EQc4.1. To answer your question, it seems that the product you reference could fall under High Performance and you could list it as such. However, I haven't done so myself.
