FAQs about MRc2 :

If a company provides an EPD but it does not mention on it that it meets the ISO standards required, can we still submit it for LEED or do we need to have that verification?

How do you recognize each type of EPD?

NC-v4.1 MRc2:Environmental Product Declarations

Multiple EPDs for the same material

Dear All,

 

In a certification project, we received 4 different EPDs for structural steel. These EPDs are from different manufacturer’s and have different declaration numbers.

Can I consider every one of them or can I only count 1 as an EPD for structural steel?

 

Thanks in advance,

My assessment would be if they are product-specific, Type III EPDs specific to each manufacturer, you may be able to count them. If it was the same industry-wide EPD that would be different. The only question I'd have is USGBC looks to see if they materials are inter-dependent - i.e. could you have ony component w/o the others. For example, on interior metal studs, they count that as one product - rather than counting studs vs track vs fasteners, etc as separate products, even if they are listed separately on the EPD
