FAQs about MRc3 :

The credit language says “Products meeting recycled content criteria are valued at 100% of their cost for the purposes of credit achievement calculation.” How much recycled content has to be in a product for 100% of its cost to count toward credit achieve

Is there any way around the requirement that no more than 30% of the materials used to meet Option 2 be structure and enclosure items?

If Sustainable Agricultural Network (SAN) certification isn’t required for agricultural products to comply with Option 2, does the manufacturer still have to provide documentation of third-party verification?

For the manufacturer “take-back” pathway under Option 2, does the extended producer responsibility program have to be run by the manufacturer?

Are there other ways the products can contribute to Option 1?

Can Corporate Sustainability Reports from the manufacturers of the products I’ve selected help me achieve the Option 1 point for “raw material source and extraction reporting?”

Regional material distance calculation method

According to LEED 2009, there were alternate distance calculations available that applied to products shipped by rail or ship. These calculations were based on ratios established for each shipping method. I have not been able to locate officially established recognition of these ratios and their acceptability for documentation towards LEED V4 credit.

Additionally, assuming these ratios are still available for use with LEED V4, are the credit documentation of those distances as presented with LEED 2009 still applicable as well?

Sure could use some help with this.
