Occupancy vs. Vacancy Sensors

Occupancy vs. Vacancy Sensors

Vacancy sensors take that control one step further with a manual on setting, as opposed to automatic on. When an occupant enters a space, they must physically change the lighting to the on setting. This allows the occupant to determine if overhead lighting is needed or if the ambient sunlight is sufficient. Like occupancy sensors, vacancy sensors also feature automatic off and time delay settings that respond to the occupant exiting the space.

By adding a layer of user control, it is easy to see how vacancy sensors can provide additional efficiency simply by allowing occupants to turn on lights only when needed.

Occupancy sensors have recently been utilized to control HVAC systems as well. When a space is unoccupied, the sensor allows the temperature to drift a few degrees higher on warm days or lower on cold days – just enough to impact energy use without causing significant discomfort to an occupant that enters the space. The sensor will quickly return the space to the designated set point, or to the temperature requested on the connected thermostat control, when the space becomes occupied.

Although subtle control changes can yield significant energy savings, they may seem insignificant on a zone-by-zone basis. When applied over tens or hundreds of thousands of square feet, the cost benefits can quickly add up in the form of reduced electric utility bills. LV energy Systems occupancy sensor / vacancy sensors, commonly referred to as “motion sensors” or “motion detectors” or “motion light sensors” for commercial and residential applications. These devices use passive infrared, combined with multi-sensing strategies for sensing occupancy or vacancy. 

The Luminetworx™ sensors go a step further and incorporate an optional daylight sensing feature into the overall occupancy sensor design with the use of a built-in photocell. If enough natural daylight is coming into a space, the occupancy sensor will not activate the connected lighting, even if people enter the room. This prevents the lights from being used when they’re not needed. And if it gets dark outside and the amount of daylight into a room drops while people are still in it, the occupancy sensor and photocell will pick up on this and turn on the lights automatically.

Luminetworx™ offers a wide variety of light fixtures, including long-lasting LED high bay lighting, recessed ceiling lights, commercial pendant lights, and commercial exterior LED strip lights and residential fixtures.

Our solutions are ideal for any type of home, including single family homes, condos, and townhouses.
