Energy Current Tip: The Energy Efficient Benefits of Occupancy Sensors

Monday, October 22nd, 2012

Do you constantly leave a room and forget to turn off the lights? If so, you are not alone, but you could be spending much more on your monthly energy bills then you would like. And if you own or operate a commercial facility, the impact could be even greater. In fact, lighting can account for as much as 40% of a commercial facility’s energy use. So, as you can see, better managing lighting can be a great way to reduce spending.

The Solution: Occupancy Sensors.

Originally designed for security systems, occupancy sensors have since been modified for residential and commercial use to better manage a building’s lighting needs. These sensors detect activity within a room and automatically turn lights on. Occupancy sensors can also detect when a room is vacant, turning lights off once occupants have left.

The Result: According to the U.S. Environmental Protection Agency, the use of occupancy sensors can help reduce energy costs by…

  • 40% to 46% in classrooms


  • 13% to 50% in private offices


  • 30% to 90% in restrooms


  • 22% to 65% in conference rooms


  • 30% to 80% in corridors


  • 45% to 80% in storage areas



Of course, energy savings will vary depending on the size of the room, the type of lighting used, and occupancy patterns.

In the end, occupancy sensors will not only help lower energy costs, but they can help improve security and reduce light pollution, while also increasing convenience.

The Current State of Electricity in the United States
