Where offices waste power
Lights left on in empty cabins, ACs running in meeting rooms nobody booked, the whole floor lit on a Saturday for two people, and the last person forgetting to switch everything off — this is where most offices waste electricity. Lighting and air-conditioning are typically the largest controllable loads in an office. Automation tackles them without relying on anyone remembering.
Lighting control
- Occupancy sensors in cabins, meeting rooms, washrooms, pantries and store rooms switch lights off when the space is empty.
- Daylight sensors dim lights near windows when there is enough natural light.
- Schedules switch off general lighting after office hours, with an override for late workers.
- Corridors and staircases on motion sensors at reduced level after hours.
AC control
- Schedules start the AC shortly before the office opens and stop it at closing time.
- Meeting-room ACs turn on with occupancy or a booking, and off when the room empties.
- Setpoint limits stop units being set to 18 °C; the Bureau of Energy Efficiency has made 24 °C the default setting for new room ACs.
- Central “all off” for the facility team at the end of the day.
Meeting rooms
One keypad or touch panel at the door sets the room for a presentation: lights dim at the screen end, blinds close, the display turns on and the AC starts. Another button returns the room to normal. Scenes can also be triggered by the room booking calendar, so the room is ready when the meeting starts and switches off when it ends.
Hybrid Work and Office Security →Typical savings areas by space type
| Space | Main control |
|---|---|
| Cabins | Occupancy sensor for lights and AC |
| Meeting rooms | Occupancy or booking-based lights and AC |
| Open work areas | Schedules and daylight dimming near windows |
| Washrooms, stores, pantries | Occupancy sensors |
| Corridors and staircases | Reduced level after hours, motion to full |
Access and visitors
Office automation often ties in with access control: staff enter with a card, face or fingerprint, and the same system can switch on their zone’s lights and AC. Visitor management records who came in and when. Linking access with attendance avoids two separate systems.
See our biometric and access control service →Energy monitoring
Meters on the main distribution board and key sub-circuits show where power goes — by floor, by area or by system — and highlight waste, such as an AC that never switches off. Many buildings that fall under India’s energy conservation building codes also have to provide lighting controls and metering; your architect or consultant can confirm what applies to your building.
Rolling it out in an existing office
- Start with the biggest waste: meeting rooms, cabins and after-hours lighting.
- Use wireless sensors and controllers that fit existing wiring to avoid disruption.
- Add AC control through the AC’s own controller interface or IR controllers for split units.
- Review energy data after a month and adjust schedules.
Quick answers
How much can office automation save?+
It depends on how the office runs today. Offices with lights and ACs often left on see the biggest drop. Energy monitoring shows the actual saving after the first month.
Will staff be left in the dark?+
No. Sensor delays are tuned to how each space is used, and wall switches always override.
Can it work with our split ACs?+
Yes, through IR controllers or the AC brand’s own controller, depending on the model.
Can the facility team control everything centrally?+
Yes, from a dashboard or app, with phone access for managers.
Do occupancy sensors work for people sitting still at a desk?+
Presence sensors designed for offices detect small movements. Delays and sensitivity are tuned during commissioning.
Can automation link to our access control?+
Yes. Access events can switch on zones as the first person arrives and off after the last person leaves.
