Please, I have a question on this subject. We have a "curtain wall" for a project, do I have to have an EPD for the complete curtain wall assembly or the EPD of glazing alone can count in LEED? For example I have AGC glazing wich had an EPD and aluminum profiles from company X which does not have EPD, is this acceptable from a LEED? Your point of view?

Sara, I don't see an issue with counting the EPD for the glazing. The goal is to tally up a total number of EPDs. There is not a rule about scope. Under this logic, a valid EPD for glazing should not be disqualified just because it didn't encompass the whole curtainwall. You might have an issue if you tried to double-count an EPD for the glazing on its own, and an EPD for the curtainwall containing that glazing.
