Is cement backer board for tile work required for EQc4.6 compliance? It is technically not gypsum board which is what the credit requires. Thanks!

It is a part of the wall system, but you are correct that it isn't listed in the required products - therefore I think that you could get away with not having it be low-emitting.

We have received GBCI review comments that said it was to be included in the credit. However's it's not mentioned in the reference guide as a ceiling or wall component, neither is tile.

Thanks, all. I submitted this question to GBCI and according to the response, it must be included: "The LEED Green Building Design and Construction 2009 guide discusses that the credit applies to "all gypsum board, insulation, acoustical ceiling systems and wall coverings installed in the building interior". Even though cement backer board would not by considered gypsum board, we believe it would still be considered an interior wall covering of sorts. Therefore we recommend you include it in your submission for IEQc4.6."
