Period: B = baseline (builds the model) · R = reporting (savings measured against the model). Driver = production units, tonnes, DJU/HDD, hours…
The ISO 50001 §6.3/§9.1 engine room: build a regression baseline (kWh = a·driver + b) from your baseline-period months, check R² ≥ 0.75, then track the reporting period with predicted-vs-actual and a CUSUM of savings — the IPMVP option C logic, free.
