as part of this prerequisite and then writing specifications to required low embodied carbon alternatives.
Projects must identify the three primary contributors to embodied carbon, focusing on materials or processes with the highest carbon emissions. For each of these key sources, provide a detailed explanation of how the team evaluated and implemented project-specific strategies to reduce their environmental impact. A hot spot analysis is mandatory to identify the most carbonintensive materials, allowing teams to focus on areas with the greatest potential for impactful reductions.
DOCUMENTATION
| Project types | Options | Paths | Documentation |
|---|---|---|---|
All | Embodied Carbon | All | Bill of Materials (worksheet) that lists the quantities of interior materials and furniture used on the project, along with the cradle-to-gate (A1–A3) embodied carbon emissions for each material. Provide a description of the data sources utilized to determine the embodied carbon values for each material. Include justification of baselines (regional, industry, similar construction type, etc.) utilized if EPA GSA, CLF, or other recommended embodied carbon values are not available. Projects using life-cycle assessment or embodied carbon software tools may report the results from their tool. |
All | Embodied Carbon | All | Provide alternative documentations if EPDs are not available. |
All | High- Priority Embodied Carbon Sources | High- Priority Embodied Carbon Sources | Document the top three high priority embodied carbon sources and describe the solutions considered to reduce the impacts. |
