I am under the impression that Regional material distance calculation option 2 (travel by sea, rail, etc.) is not allowed in LEED Retail-NC projects, but I'm finding conflicting information. Can anyone identify where the definitive statement can be found (whether or not we can use Option 2 in Retail-NC projects)?

The USGBC website lists Option 2 in the credit language for Retail-NC MRc5, which makes me think we can use it. BUT the BDC Material and Resource Calculator (Aug 2012) has a note in the Option 2 columns that states "Not available for LEED for retail projects".

I'm trying to figure out what the definitive rule is: Can we use Option 2 for LEED for Retail NC? I'm asking about NC, not CI.

Does anyone have any insight? Thanks!!!
