Occupancy Sensor Energy Savings

Construction volume weighted average energy savings are 17 8 for obc using advanced occupancy sensors and 5 9 using common occupancy sensors.

Occupancy sensor energy savings.

General information occupancy sensors detect the presence or absence of people and turn lights on and off accordingly. Provides unique and valuable data about occupancy sensor demand reduction and energy savings potential. Demand reduction and energy savings using occupancy sensors. Nema lsd 22 2001 r2020 status.

Savings from retrofit of obc using common occupancy sensors for lighting and terminal boxes in the large office building that initially has no obc for locations in the 15 u s. By combining an inexpensive camera with a high speed microprocessor and algorithms the nrel s occupancy sensor can recognize the presence of human occupants more than 90 percent of the time. Occupancy sensors are ideal for rooms where lights are frequently left on bathrooms playrooms bedrooms walk in closets and rooms you may often enter with your hands full such as a laundry room foyer or garage. For example if occupancy sensing is installed in a large open plan office and each sensor s controlled area is 125 sq ft.

Occupancy sensors detect indoor activity within a certain area. They provide convenience by turning lights on automatically when someone enters a room and save energy by turning lights off soon after the last occupant has left the room. The study entitled demand reduction and energy savings using occupancy sensors monitored 158 rooms at 60 buildings for occupancy and lighting status over a 14 day period. In the example above i used fluorescent highbays to prove a point.

They may reduce lighting energy consumption by 50 percent or more in some circumstances but the savings for any given installed sensor can be much less. In addition to. Occupancy sensors must be located where they will detect occupants or occupant activity in all parts of the. Occupancy sensors energy saving sensors.

In addition to commercial use occupancy sensors are ideal for energy efficiency and cost savings in the home. Thats a 2 095 00 savings on your yearly cost of electricity. Many consider t5 highbays fixtures excellent upgrades to older metal halide lighting and they are but by utilizing occupancy sensors you can take those savings much farther. Occupancy sensors can reduce energy waste by as much as 68 and increasing energy savings by as much as 60 according to a new study conducted by the environmental protection agency epa.

An analysis of the energy and cost savings potential of occupancy sensors for commercial lighting systems introduction since their introduction more than 20 years ago occupancy sensor controls for lighting systems have promised significant energy and dollar savings potential in a variety of commercial lighting applications.
