1. Delete the phrase "There are no substantive changes to prerequisite requirements;", capitalize the R in "Refer", and add the words "edits and" after the words "with the following".

2. Add new section "Behind the Intent:". Below the section header add the following text:
"Hydrochlorofluorocarbons (HCFCs) have shorter atmospheric lives than CFCs, but they still contribute to ozone depletion. Similar to CFCs, HCFCs have phase-out dates scheduled under the Montreal Protocol.

Both HCFCs and CFCs must be addressed to meet this prerequisite."

"Wherever CFCs are mentioned in the LEED v4 reference guide, the guidance also applies to HCFCs."
