NAVFAC is 'requiring' that projects achieve an ID credit for Bio-based materials. Per the USDA (the referenced standards), this simply means using from a list of material types that amount to either wood-based or would otherwise show up in the rapidly renewable materials credit. Does anyone have a sense of what sort of verification standard for compliance that the USGBC might accept as an ID credit? Even better, can anyone share a successful effort in achieving a credit like this - if one even exists?

Robert, I am not familiar with the NAVFAC requirements, but... LEED doesn't award ID credits for topics that are already covered by an existing LEED credit, except through the Exemplary Performance path. You would need to earn the rapidly renewable credit (MRc6), and you can earn IDc1 for doubling the MRc6 threshold. The MRc6 requirements are more restrictive in some cases than the USDA biobased materials, however.

You have identified my big problem with what they are suggesting. If is was meant to simply be exemplary performance, wouldn't they have just listed that as a requirement rather than showing a completely new credit. Because it is in black and white in their written guidelines, I have to think that they have something in mind or have had a past team succesfully submit something. NAVFAC doesn't seem to know why themselves, so I am hoping that someone in LEEDuser might actually have one of these potential past successful submission.

Robert, you might also post this question to the MRc6 forum.
