Projects that used EAp3: Minimum Energy Performance, Option 3 must use the same historical baseline reporting period for compliance with this path.
Historical baseline total GHG emissions are calculated based on site energy use per energy source determined in the historical baseline, and the greenhouse gas emissions factors for each energy source serving the project.
Use the same GHG emissions factors for the current year and the historical baseline for fuels. For electricity and district energy, projects may either use the same GHG emissions factor for the current year and the historical baseline or use the GHG emissions factor for the historical baseline year referencing the same data source used for the current reporting period. For example, if using published utility GHG emission factors for the current reporting period, the project may use the GHG emissions from the same utility published for the historical reporting year.
Use grid electricity emission factors for Tier 1 or Tier 2 renewable energy generation occurring during the historical period.
DOCUMENTATION
| Project types | Options | Paths | Documentation |
|---|---|---|---|
Existing Buildings | Option 1 | Path 1 | Percentage reduction below on-site combustion emissions target by comparing the greenhouse gas intensity (GHGi) for the 12-month reporting period with the_ENERGY STAR® NextGen™_ target |
Existing Buildings | Option 1 | Path 2 | Percentage reduction below on-site combustion emissions target by comparing the on-site combustion emissions for the 12-month reporting period with the historic baseline on-site combustion emissions |
Existing Buildings | Option 1 | Path 2 | If not provided in EAp3: Minimum Energy Performance: historical baseline site energy consumption per energy source for the 12-month baseline reporting period, and a narrative description confirming similar occupancy for the historical baseline, and describing any normalization |
Existing Buildings | Option 1 | Path 2 | If normalization is applied, documentation or calculations supporting determination of normalized results |
Existing Buildings | Option 1 | Path 3 | Percentage reduction below on-site combustion emissions target by comparing the on-site combustion emissions with the On-Site Combustion Emissions Intensity Targets for the project’s building type(s) and climate zone in Appendix II based on_ASHRAE 100-_ 2024 |
