Hello all, 

For a curtain wall case, the manufacturer has their own windows and some extrusions and insulation product and it is possible for them to have EPDs of their own. For their curtain wall product, they would prefer to submit a LEED package whereby they package the existing EPDs - rather than needing to develop their own EPD which would only count for 1 product.  

Do you have any comments related? What they would be looking for is a credit interpretation ruling that says yes - you can provide EPDs for the components in a prefab system rather than a single EPD for the system.

Thank you
