Invoice for Wood in Assembly (Display Boards)

Carly - What specification division have you been placing the markerboards in? They are commonly a Furnishing, Fit-up and Equipment (FFE) item that is not included in the LEED NC materials boundary (which includes the conventional specification sections 2-10 + some division 12 items like pre-fabricated casework that can also show up in division 6 if it is custom fabricated). You might consider simply not including them in your calculations as they are a furniture item - this would be different for LEED CI which reports on furniture. Off course if you delete the markerboards, it will change the percentage of other materials credits that rely on the total materials value of the project for their calculations (unless you are using the default material value). I don't have any special methods for getting 'split' invoices from a manufacturer to offer. However, if you can not get one split, maybe you can get an invoice for the entire markerboard, in which case another approach (besides deleting the markerboard from the calculation since it's furniture and outside the NC material reporting boundary) might be to include the entire markerboard value as 'new wood' (assuming it doesn't throw you below the 50% baseline for earning the credit). Since the negative impact counts against earning the credit, and not towards earning it, the reviewer might find the approach acceptable(?). Just a thought...
