Perform a detailed assessment to determine the total estimated annual building energy consumption from all plug and process equipment, even when regulated under ASHRAE 90.1 :

  • Receptacle equipment

  • Cooking equipment

  • Refrigeration equipment

  • Conveyance equipment including elevators, escalators, or moving walkways

  • Process heating or process cooling (e.g., for manufacturing processes)

  • Data center IT equipment and Electrical Loss Component

  • All other process energy used to support a manufacturing, industrial, or commercial activity other than conditioning spaces and maintaining comfort and amenities for the occupants of a building.

For projects where startup plug and process energy usage projections are lower than estimated full build-out usage, use either the full build-out usage or a lesser value representing the maximum plug and process usage possible from the building power and thermal energy generation capacity installed in the project scope of work.

For each process efficiency measure implemented in the project, document that the efficiency measure is not conventional practice. Examples include:

  • A recent study with researched tabulations or monitored data establishing standard practice for the given application in similar newly constructed facilities.

  • A new-construction utility or government program that provides incentives for the measure.

  • A document showing the systems used to perform an analogous function in similar facilities built or reconstructed within the past 10 years.

  • Applicable prescriptive requirements from the version of ASHRAE 90.1 or equivalent standard used for EAp2: Minimum Energy Efficiency .

Use the conventional practice references to define the baseline systems. Provide detailed calculations and supporting narrative justification for any variations in baseline and proposed energy use.

Option 2. Energy Simulation

Option 2 rewards future source energy improvement below a Performance Index Target (PIt) documented per ASHRAE 90.1, Appendix G Performance Rating Method (PRM). The credit structure prioritizes efficiency over on-site renewable energy, setting the performance
