USGBC’s LEED V4 specific to Healthcare and Schools has a “Low-emitting materials” credit under the category “Indoor Environmental Quality”. The intent of this credit is to reduce concentrations of chemicals that may harm air quality and the environment.

Different materials must meet different requirements to be considered compliant for this credit. The building exterior is defined as everything outside and inclusive of the primary and secondary weatherproofing system, such as waterproofing membranes and air- and water-resistive barrier materials.

USGBC has published addendum number 100002250, which added a definition of hot-mopped asphalt for roofing to be:

"a mopping-grade oxidized asphalt as defined by NIOSH: "an oxidized asphalt used principally in the construction of built-up roofing (BUR) and some modified bitumen systems; mopping-grade asphalts are produced in four grades (Types I through IV), according to the steepness of the roof”.

Since Monolithic Membrane 6125 is not an oxidized asphalt, under this revised definition, Monolithic Membrane 6125 meets LEED v4 requirements and is not restricted from use on healthcare and school projects.
