DOCUMENTATION
| Project types | Options | Paths | Documentation |
|---|---|---|---|
| All | Option 1. Whole- building Life Cycle Assessment | All | Provide Baseline LCA report and raw WBLCA file. Provide Proposed Design LCA report and raw WBLCA file. Provide comparative excel file or input into LEED form comparing the outputs of the baseline vs. proposed reports to identify reductions achieved by major material category or strategy. Align with ECHO. |
| All | Option 1. Whole- building Life Cycle Assessment | All | Justification of used baselines (regional, industry, similar construction type, etc.) if EPA GSA, CLF, or other recommended embodied carbon values are not available. |
| All | Option 1. Whole- building Life Cycle Assessment | All | Narrative of process to use WBLCA to inform design. |
| All | Option 1. Whole- building Life Cycle Assessment | All | Summary of strategies that resulted in reductions. |
| All | Option 1. Whole- building Life Cycle Assessment | All | Confirmation that material quantities in the reports represent as-constructed final quantities, or as-designed quantities (provided quantities did not change more than 10% from design through construction). |
| All | Option 2. EPD Analysis | Path 1. Project- Average Approach | Results of analysis using EC3 or similar tool/software or EPDs. |
| All | Option 2. EPD Analysis | Path 1. Project- Average Approach | Justification of used baselines (regional averages, industry averages, etc.) if EPA GSA, CLF, or other recommended embodied carbon values are not available. |
| All | Option 2. EPD Analysis | Path 1. Project- Average Approach | Confirmation that material quantities in the reports represent as-constructed final quantities, or as-designed quantities (provided quantities did not change more than 10% from design through construction). |
| All | Option 2. EPD Analysis | Path 1. Project- Average Approach | Narrative of major savings/changes. |
| All | Option 2. EPD Analysis | Path 2. Materials Type Approach | Provide summary sheet/table and the product-specific Type III EPDs for the as-constructed materials. |
| All | Option 2. EPD Analysis | Path 2. Materials Type Approach | Provide justification of used baselines if EPA GSA, CLF, or other recommended embodied carbon values are not available. |
| All | Option 2. EPD Analysis | Path 2. Materials Type Approach | Confirmation that material quantities in the reports represent as-constructed final quantities, or as-designed quantities (provided quantities did not change more than 10% from design through construction). |
| All | Option 4. Track Carbon Emissions from Construction Activities | Paths 1 and 2 | Description of tracking process initiated and how it was monitored and logged. |
| All | Option 4. Track Carbon Emissions from Construction Activities | Paths 1 and 2 | Proof of emissions tracking (such as monthly tracking logs, photos or log of shipments inbound/outbound from jobsite, and associated emissions estimates). |
| All | Option 4. Track Carbon Emissions from Construction Activities | Carbon emissions calculations (spreadsheet or report). |
