Has USGBC taken into consideration the overlap for the Low-Emitting Materials categories with v2009 (NAUF) and v4 General Emission Standard (GES) and whether or not they would allow the GES certification in lieu of NAUF construction. Due to the CARB requirement over the past several years assembled wall products are able to meet the GES with materials which contain UF resins. The GES is a better methodology that requires VOC levels that have to be met for certification. If USGBC does not allow the use of the GES on v2009 projects it would require manufacturers to maintain 2 inventories of raw materials for the one credit. NAUF is a prescriptive requirement instead of a performance based method such as the GES.
