Control zone and operating stateControls change the active lighting state, so zone, scene and hours need to travel with the energy record.

Control item	What to name	Effect on estimate	Boundary
Lighting zone	Room, perimeter row, task zone, aisle, display wall or after-hours group.	Energy and lux comparisons change when a zone is grouped too broadly.	A zone note is not a wiring layout.
Operating hours	Hours per day, days per year and seasonal or after-hours differences.	Running cost and annual kWh move directly with the schedule.	Do not infer a current tariff or occupancy pattern from this table.
Daylight contribution	Window side, skylight area, time of reading and daylight factor where measured.	Daylight can reduce the remaining electric-light target during some periods.	A momentary reading is not an all-day daylight result.
Dimming range	Minimum output, normal task level and full-output condition.	Partial output can change kWh while the task plane still needs enough light.	Dimmer compatibility and electrical work remain outside this table.
Manual and automatic control	Switching groups, timers, occupancy sensing or daylight response stated as assumptions.	The operating pattern changes energy estimates and user comfort notes.	Connection details and commissioning need separate project notes.
Fallback condition	What happens when daylight is low, the room is occupied longer or a sensor is bypassed.	The fallback condition can define the highest load and lowest-light case.	Do not treat the most optimistic condition as the maintained result.
