Intent

To encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts. To reward project teams for selecting products from manufacturers who have verified improved environmental life-cycle impacts.

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. (10 different permanently installed products from three different manufacturers for CS and Warehouses & Distribution Centers).
  • Life-cycle assessment and environmental product declarations.
    • 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 whole product for the purposes of credit achievement calculation.
    • Product-specific Type III EPD -- Internally Reviewed. Products with an internally critically reviewed LCA in accordance with ISO 14071. Products with product-specific internal EPDs which conform to ISO 14025, and EN 15804 or ISO 21930 and have at least a cradle to gate scope are valued as one whole product for the purposes of credit achievement calculation.
    • Industry-wide Type III 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. Products with industry-wide EPDs, which conform to ISO 14025, and EN 15804 or ISO 21930 and have at least a cradle to gate scope are valued as one whole 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.
    • Product-specific Type III EPD -- Products with third-party certification (Type III), including external verification and external critical review are valued as 1.5 products for the purposes of credit achievement calculation.
    Option 2. Embodied Carbon/LCA Optimization (1 point)
    Use products that have an embodied carbon optimization report or action plan separate from the LCA or EPD. Reports shall comply with one of the criteria below for 10%, by cost, of the total value of permanently installed products in the project, or use at least 10 permanently installed products sourced from at least three different manufacturers. Products will be valued as below.
    Report Type Reference Document(s) for the Optimization Report Report Verification Valuation
    Embodied Carbon/LCA Action Plan Product-specific LCA or product-specific Type III EPD Prepared by the manufacturer and signed by company executive ½ product or 50% cost
    Reductions in Embodied Carbon: less than 10% reduction in GWP relative to baseline Baseline: Product-specific LCA, Product-specific Type III EPD, or Industry-wide Type III EPD Optimized: Product-specific LCA or product-specific Type III EPD Comparative analysis is verified by an independent party 1 product or 100% cost
    Reductions in Embodied Carbon: 10%+ reduction in GWP relative to baseline 1.5 products or 150% cost
    Reductions in Embodied Carbon: 20%+ reduction in GWP and 5%+ reduction in two additional impact categories, relative to baseline Baseline: Product-specific LCA or Product-specific Type III EPD Optimized: Product-specific LCA or product-specific Type III EPD 2 products or 200% cost
    Note: Reference documents for the optimization reports must be compliant with Option 1.
    Impact categories:
    • global warming potential (greenhouse gases), in CO2e;
    • depletion of the stratospheric ozone layer, in kg CFC-11e;
    • acidification of land and water sources, in moles H+ or kg SO2e;
    • eutrophication, in kg nitrogen equivalent or kg phosphate equivalent;
    • formation of tropospheric ozone, in kg NOx, kg O3 eq, or kg ethene; and
    • depletion of nonrenewable energy resources, in MJ using CML / depletion of fossil fuels in TRACI.
    For credit achievement calculation, products sourced (extracted, manufactured, purchased) within 100 miles (160 km) of the project site are valued at twice their base contributing cost (or number of products), up to a maximum of 200% of cost, or 2 products.

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.
