What belongs behind a building-energy result?

An energy result needs a model, an operating scenario and an explicit comparison basis—not just a percentage saving.

How to use this idea

DOE describes EnergyPlus as a whole-building engine that models physical heat-transfer and building-system behavior. Our proposed evidence checklist adds the exact engine version, weather input, geometry, schedules, system assumptions and baseline to every reported comparison. We have not run EnergyPlus for this section.

Worked illustration

Two synthetic options cannot support an envelope-only saving claim if their occupancy schedules differ too. Either hold the schedule fixed or describe the comparison as a combined scenario change.

All numerical examples here are synthetic, not measured building results.

Checks before relying on a result

  • Preserve baseline and alternative inputs.
  • Distinguish annual energy from peak demand.
  • List failed runs and warnings, not only successful outputs.

What this does not establish

No actual building energy savings or performance is established. Simulation is not a utility measurement.
