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?

Does FloorScore apply to subfloor surfaces?

I have a project where I received a submittal for a subflooring hard surface material. Since this is not the surface that is to be exposed to the interior space, with or without carpet or other finishes, should it still comply with FloorScore standard? I ask because when i reached out to the manufacturer, he said that since it is subflooring it does not need to meet the FloorScore standard.

Hi Edgar, it would not be covered by FloorScore, but it would still have to meet CDPH Standard Method v1.1.
