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?

Resinous Flooring - Healthcare Project

My project is installing resinous (pourable) flooring in a surgical addition. Does the mortar (binder) get logged in under the category of Ceramic Tile Adhesive (65 g/L)?

Catherine, that doesn't seem exactly right, but I'm not sure what else to suggest. How does the manufacturer classify it?

The product is actually made of several components...all of which are listed as an industrial maintenance coatings. Industrial Maintenance coatings are listed under Exterior Coatings and this is an interior application. Also if you read SCAQMD 1113 definition of an industrial maintenance coating (IMC), our application doesn't fit. Should I log it in as an IMC, if that is what it has been tested under? Or should it be logged in as a floor coating (FC)? Should the whole system get logged as a single coating system (whether IMC or FC)? Or should the system be broken down into its components and logged by its components? FloorScore doesn't cover this type of "flooring" per se.

Hi Catherine, What is the VOC content of the components of your product? Does your products VOC contents fall within all of the options that you list above? If so, I would just try my best to place it in one of the categories. Often judgement calls are made when working on a LEED project in helping to determine where a product goes and how it is included. If you have the VOC content information for all of the components my advice would be to list out each component in your documentation so as to play it on the safe side. Sometimes, manufacturers will provide both: a value as a combined system and also individually.
