Identify the exact unit
Record the manufacturer, model number, and rated input power from the label or manual. Do not guess the model from appearance.
PowerCost Lab · Protocol AC-01
Measure normal life,not a laboratory fantasy.
This protocol produces comparable air-conditioner readings without asking contributors to change how they live or perform unsafe electrical work.
MeasureEnergy, not rated wattage
PreserveNormal operating behavior
ProtectSafety and household privacy
Use an appropriate meter
Use an existing rated smart plug, circuit energy meter, or manufacturer energy monitor. Split and hard-wired systems may require a qualified electrician.
Measure for seven days
Reset or note the starting energy total, then measure normal use for seven complete days when possible. Do not change normal behavior to produce a cleaner result.
Record operating context
Capture the thermostat setpoint, broad climate context, unusual weather, room use, and whether other loads share the measured circuit.
Prepare private evidence
Take a clear photo or screenshot showing the energy total and period. Crop out names, account numbers, addresses, faces, and reflective surfaces.
Submit and save the receipt
PowerCost Lab redraws the image to remove camera metadata, grades the reading, and returns a private deletion receipt. Use it to check status or delete the reading and evidence.
Do not submit
Evidence that creates more doubt than confidence.
- Estimated energy presented as a meter reading
- A utility total that includes unrelated household loads
- A single instantaneous wattage reading presented as multi-day energy
- Images containing names, addresses, account numbers, or faces
- Measurements requiring unsafe or unqualified electrical work
- Readings you do not have permission to share
