Extracted Content

• Heating demand, for climate zones 3–8, measure total hourly thermal energy consumed for space heating, service water heating, and process heating.

  • Cooling demand, for climate zones 0–5, measure total hourly thermal energy consumed for space cooling and process cooling.

Report the monthly peak hourly heating demand and the monthly peak hourly cooling demand for the current 12-month reporting period and for a baseline 12-month reporting period occurring within eight years before the end of the 12-month reporting period. Comparing the current reporting period to the baseline reporting period, demonstrate a 10% reduction in the sum of the maximum monthly heating demand and the maximum monthly cooling demand.

REQUIREMENTS EXPLAINED

This credit rewards reduced peak demand to limit strain on the electric grid during peak summer and winter operation when grid capacity and associated grid emissions are highest, and to improve the project’s resilience.

There are two options for compliance. Projects can demonstrate a 10% reduction in either peak electric demand or peak thermal demand compared to a historical baseline.

All Projects

HOURLY DATA

Hourly data is required for all projects pursuing this credit. For projects pursuing Option 1, monthly electric utility bills that report peak electric demand may be used. Teams that do not have at least 24 months of hourly metered data capturing peak electricity or peak heating and cooling demand are ineligible for this credit.

Use the same meters to report peak demand for the historical baseline and the current reporting period to ensure accuracy in the reported data or provide additional justification on why different meters were used.

HISTORICAL BASELINE

The historical baseline represents a consecutive 12-month period that occurred more than eight years before the end of the reporting period. Projects that used EAp3: Minimum Energy Performance, Option 3 or EAc1: Greenhouse Gas Emissions Reduction Performance, Option 3, Path 2 must use the same historical baseline for this credit, unless the project added monitoring functionality to record peak demand after that baseline reporting period started.
