cutsheets

Cutsheets is somewhat of a catch-all term that LEED uses to refer to manufacturer documentation. For MRc5 you will need proof from the manufacturer that confirms what percentage of the product, by weight, meets both of those criteria (i.e. manufactured within 500 miles of your LEED project and from raw materials which were harvested/extracted within 500 miles of your LEED project). So you would want documentation from the manufacturer to clearly state where the product is manufactured and where each of the raw materials are extracted/harvested. It is most helpful if the manufacturer also includes the percentage, by weight, that each raw material comprises within the final product.

Make sure to pay special attention to/note that it is where the raw materials are extracted/harvested, not where the supplier/vendor of those materials is/manufactured them.

Your supporting documentation must be clearly attributable to the manufacturer. USGBC does not accept claims from the contractor/subcontractor. There is not a single method/option - the important thing is to make sure all your supporting documents are clearly linked to the manufacturer so there are no questions about who provided the document/verified the product's contributions. Typically we want any verification to be on manufacturer letterhead or with the manufacturer logo printed on it.
