Were'a a GC. Does insulation (board and/or batt) need to also be NAUF either under this credit or elsewhere? I'm fairly sure it doesn't for LEED NC v2009 under EQc4.4 (maybe I'm wrong.) If we want the Subs to only use a NAUF insulation, how I can enforce that through LEED? The Specs have not stated that requirement only no asbestos. I am aware about no CFC/HCFC.
My question is about NAUF. Thanks, Debra
