I'm working on a project that is classified as "New Construction" & not a "School Project"

My LEED Reference guide for green building design & construction updated as of June 2010 states the following on page 487 (IEQ 4.3)

"All hard surface flooring must meet the requirements of the FloorScore Standard"

My rubber flooring for the project is in compliance with Green Guard, & not floorscore (which is more stringent than floorscore) however there is absolutely no reference to Green guard under IEQ 4.3 in the LEED reference guide.

IEQ 4.5 on the other hand (School Projects)... states that furniture and seating must be greenguard children and school certified.

My question is
" Will this rubber flooring meet the requirements of IEQ 4.3 given that it's not certified by floorscore standard? ........Please note that when you visit LEED online, and download the form for IEQ 4.3, it says the following

"Combination of Carpet and Rug Institute, South Coast Air
Quality Management District, and FloorScore referenced standards"

It makes no reference to green guard at all. My educated guess this rubber flooring does not meet the reqs of IEQ 4.3, only because it's not certified by floorscore. If it does not, can I challenge this with GBCI since green guard is more stringent than floorscore? Please note that I still have not installed the rubber flooring.

Also please note that this very website states "Resilient flooring, rubber flooring, and prefinished wood flooring all must be FloorScore or Greenguard Children and Schools certified"

Can someone please provide a solid response, and if you think my product meets the reqs of IEQ 4.3, can you please back it up with hard evidence, or tell me which website to go to. Again the LEED reference guide makes no reference to Green guard nor does the LEED Online form, which makes me think that this product won't qualify, and maybe I can challenge it with GBCI.
