MR Credit: Building Product Disclosure and Optimization—Environmental Product Declarations

Option 1. Environmental Product Declaration
  • Documentation must highlight or call-out the Manufacturer Name, Description of Material, EPD Program Operator, and EPD Type. Be sure that the EPD or EPD summary clearly indicates the impact method used (e.g. TRACI, CML).
  • Be sure the EPD type entered into the calculator corresponds to the information on the supporting documentation.
  • Because EPDs vary, verify that all EPDs included are a cradle-to-gate scope and highlight this information in the documentation.
  • Be sure that the product EPDs comply with the relevant referenced standards and that the relevant information in them has been highlighted. The EPD must comply with ISO 14025, ISO 14040, and ISO 14044; the PCR must comply with EN 15804 or ISO 21930. Either the full EPD or an EPD summary and a link to the full Environmental Product Declaration (EPD) must be provided. If the link is separate from the summary, be sure to cross check that the same product is referenced on both.
  • Note that LEED Interpretation 10425 states that a single industry-wide (generic) EPD can be used for up to 10 products listed within the industry-wide EPD, provided that each application has separately reported impacts within the EPD.
Option 2. Multi-Attribute Optimization
  • Ensure that structure and enclosure materials do not constitute more than 30% of the value of compliant building products.
  • Note that LEED Interpretation 10415 states that in addition to the option outlined in the credit language, products that meet any of the following requirements can also contribute towards Option 2:
    1. Demonstrate reduced impact with a product-specific EPD against an industry-wide generic EPD, provided the manufacturer was part of the study and the two conform to the same PCR.
    2. Demonstrate reduced impact of the same product, over time, with two product-specific EPDs.
