A factory has many different areas, each area has its own functionality and a different approach to energy management for each.

1. Open offices: Due to the nature of the work in factories, many office workers are often not at their desks. There should be switches in each section, during work hours, the lights are turned on in their respective sections, after office hours, each section would have automatic controls, the last person to leave simply presses one switch to turn off all the lights.
2. Small offices and workshops: press once to turn on and press again to turn off, the lights and air conditioning would be controlled at the same time.
3. Meeting rooms: press one to turn on, press again to turn off, the lights and air conditioning would be controlled at the same time.
4. Stock room and machine room: these occupy large areas, and should be divided into sections, each section should have its own sensor control with automatic delayed off, if the lights need to remain on for prolonged periods, a switch would be available nearby which can be pressed to keep the lights on indefinitely. Another press would then restore the operating mode to auto off. Or one can make use of digital switches and have them installed in multiple locations enabling multiple access.
5. Hallways: whether the area will be lit or not during the day will depend on the location of the hallway. Or it could be equipped with sensor control with auto off. It could also have multiple switches along the length of the hallway and it could also be centrally controlled.
6. Outdoor lighting: Depending on the location, each month would have its own schedule turn on time. They would also be centrally controlled.
7. All the lights and air conditioning would be centrally controlled, each section would have timer control.
8. Conference halls and briefing rooms: digital switches would be used to control patterns. Air conditioning would be controlled by digital switches.
9. Workshop machinery: Low voltage switches would be used on site, and would be linked to the control panel via a digital wiring, which would allow the operator to control the machines from where they are instead of having to go back and forth to the machine room, and can reduce the unnecessary running of the machines when not in use.
10. Workshop lighting: each section would be separately controlled and also centrally controlled. No need to have them all controlled as a group.
11. Air conditioning: there would be local switches in the working areas which would work in conjunction with central control.
12. Emergency power load control: during a power outage, the generator power would be utilized optimally among the various loads depending on their priority. Once utility power is restored, the loads would switchover back to the main power in the right sequence.
13. Emergency help button: When there is an accident, the nearest emergency button can be pressed which would then light all the emergency lights, sound the alarm, and show the location of the emergency on the control panel.
