Option 2. Environmental Product Declaration (EPD) Analysis (1–3 points New Construction, 1–4 points Core and Shell)

PATH 1. PROJECT-AVERAGE APPROACH (1–3 POINTS)

Earn points for reducing embodied carbon of the project based on EPD data for the procured materials compared to industry average values. Points are awarded according to Table 1 for the whole-project weighted average of applicable material categories. In dustry averages for material categories are defined by the U.S. Environmental Protection Agency (EPA), the most recent Carbon Leadership Forum (CLF) Material Baselines report, or similarly robust and widely recognized publications, and industry-wide EPDs applicable to the project region.

Projects must track the GWP/unit of the materials installed, reconciling the design-phase embodied carbon intensities if materials or GWP values have changed. The reconciliation of material quantities is not necessary unless quantities have changed more than 10% from design through construction. Projects must use project-specific material quantities and identify productspecific or facility-specific Type III EPDs for covered materials to demonstrate reductions. Biogenic carbon may only be included for calculations that include C-stage emissions.

PATH 2. MATERIALS-TYPE APPROACH (1–2 POINTS NEW CONSTRUCTION, 1–3 POINTS CORE AND SHELL)

Earn points according to Table 1 by demonstrating that structural, enclosure, and hardscape materials for targeted material types have lower embodied carbon impacts than industry benchmarks as demonstrated by product-specific Type III EPDs. Track the GWP per unit of the materials installed, reconciling the design-phase embodied carbon intensities if materials or GWP values have changed. The reconciliation of material quantities is not necessary unless quantities have changed more than 10% from design through construction.

A weighted-average approach can be used to calculate average embodied carbon intensity values within a product category.

Industry averages for embodied carbon intensity values are defined by the U.S. EPA, the most recent CLF Material Baselines report, or similarly robust and widely recognized publications and industry-wide EPDs applicable to the project region.
