Since v4.1 has reorganized product categories, is there a change in the "boundary" we have to look at? "everything within the waterproofing membrane" is still a thing in v4.1 or not? I.e. insulation is now a category by itself, does it mean we have to consider all insulation, exterior applied included or do we stick to the waterprofing membrane limit? Thank you!

The credit language requirements still start with this statement, "Use materials on the building interior (everything within the waterproofing membrane) that meet the low-emitting criteria below." Then insulation is one of the categories below. The intent of the credit is to prefer proven low-emitting materials inside the weather barrier. Exterior insulation would likely be excluded, depending on the location of the air barrier in your building envelope assembly.
