Requirements

Achieve one or more of the options below, for a maximum of 2 points.

Option 1. environmental product declaration (EPD) (1 point)
Use at least 20 different permanently installed products sourced from at least five different manufacturers that meet one of the disclosure criteria below.
  • Product-specific declaration.
    • Products with a publicly available, critically reviewed life-cycle assessment conforming to ISO 14044 that have at least a cradle to gate scope are valued as one quarter (1/4) of a product for the purposes of credit achievement calculation.
  • Environmental product declarations which conform to ISO 14025 and EN 15804 or ISO 21930 and have at least a cradle to gate scope.
    • Industry-wide (generic) EPD -- Products with third-party certification (Type III), including external verification, in which the manufacturer is explicitly recognized as a participant by the program operator are valued as one half (1/2) of a product for purposes of credit achievement calculation.
    • Product-specific Type III EPD -- Products with third-party certification (Type III), including external verification in which the manufacturer is explicitly recognized as the participant by the program operator are valued as one whole product for purposes of credit achievement calculation.
  • USGBC approved program – Products that comply with other USGBC approved environmental product declaration frameworks.

AND/OR

Option 2. Multi-attribute optimization (1 point)
Use products that comply with one of the criteria below for 50%, by cost, of the total value of permanently installed products in the project. Products will be valued as below.
  • Third party certified products that demonstrate impact reduction below industry average in at least three of the following categories are valued at 100% of their cost for credit achievement calculations.
    • global warming potential (greenhouse gases), in CO2e;
    • depletion of the stratospheric ozone layer, in kg CFC-11;
    • acidification of land and water sources, in moles H+ or kg SO2;
    • eutrophication, in kg nitrogen or kg phosphate;
    • formation of tropospheric ozone, in kg NOx, kg O3 eq, or kg ethene; and
    • depletion of nonrenewable energy resources, in MJ.
  • USGBC approved program -- Products that comply with other USGBC approved multi-attribute frameworks.
For credit achievement calculation, products sourced (extracted, manufactured, purchased) within 100 miles (160 km) of the project site are valued at 200% of their base contributing cost.

Structure and enclosure materials may not constitute more than 30% of the value of compliant building products. Projects with significant amounts of structural and enclosure materials may exceed the 30% limit by calculating an alternative structure and enclosure limit (See Calculations under Further Explanation).

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

For projects with significant amounts of structure and enclosure materials, the following calculation can be made to determine an alternative limit for the percentage of value that structure and enclosure materials can contribute to credit achievement. Note: this option is only available for projects that use the actual materials cost method (not the default cost method) to determine total project material costs.

Inquiry:

How can products contribute to earning Option 2 of the LEED v4 MR credit BPDO – Environmental Product Declarations?

Ruling:

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.

LEED Interpretation
Inquiry:

We are a manufacturer working with a program operator in Europe to develop environmental product declarations. We are looking for clarification on applicability of Option 1: Environmental Product Declaration (EPD) that requires approved products to be third party verified (Type III) with external verification in which the manufacturer is explicitly recognized as the participant by the program operator. The EPDs that we have developed for our products with the program operator meet all LEED criteria for Type III product specific EPDs as defined by ISO standards ISO 14025, 14040 and 14044 and are consistent with PCR standard EN 15804 with the exception of being covered by a third party verification that includes external verification. Per ISO 14025 or EN 15804, there is no requirement for the product declarations to be ‘externally verified’. Our EPDs follow an independent review process per Section 8: Verification of ISO 14025 standard and includes verification of conformance to ISO 14025, 14040 and 14044 as well as PCR standards. We are looking for published clarification on eligibility of independently reviewed product-specific EPDs in LEED v4.

Ruling:

Yes, these products may contribute towards Option 1 of Building Product Disclosure and Optimization – Environmental Product Declarations, Building Product Disclosure and Optimization – Sourcing of Raw Materials, and of Building Product Disclosure and Optimization – Material Ingredients.
