Connected load to annual kWhEnergy estimates stay readable when the same lighting group carries load, schedule and annual kWh together.

Energy formula	Calculation basis	Example result	Boundary
Watts to kW	Connected watts / 1,000.	240 W becomes 0.24 kW.	Only the named lighting group is counted.
Daily kWh	Connected kW x hours per day.	0.24 kW x 6 h = 1.44 kWh/day.	The hour value must match the named zone and control state.
Annual kWh	Connected kW x annual operating hours.	0.24 kW x 1,200 h = 288 kWh/year.	Annual hours need their own schedule line.
Fitting group load	Fitting count x input watts per fitting.	12 fittings x 18 W = 216 W.	Watts do not show whether the task plane receives enough light.
Replacement comparison	Existing annual kWh minus proposed annual kWh.	520 kWh - 310 kWh = 210 kWh change.	The comparison does not include tariff, demand or maintenance items.
Control case	Full-load kWh and reduced-output case kept as separate rows.	Full-output case remains visible beside the reduced case.	Do not hide the fallback condition inside one optimistic number.
