Occupancy Sensor Energy Savings

In addition to commercial use occupancy sensors are ideal for energy efficiency and cost savings in the home.

Occupancy sensor energy savings.

Occupancy sensors energy saving sensors. 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. 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. General information occupancy sensors detect the presence or absence of people and turn lights on and off accordingly.

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. Thats a 2 095 00 savings on your yearly cost of electricity. Construction volume weighted average energy savings are 17 8 for obc using advanced occupancy sensors and 5 9 using common occupancy sensors. Provides unique and valuable data about occupancy sensor demand reduction and energy savings potential.

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. Occupancy sensors detect indoor activity within a certain area. 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 must be located where they will detect occupants or occupant activity in all parts of the.

Demand reduction and energy savings using occupancy sensors. This year the energy department s national labs and facilities won 36 out of 100 awards including one for a smart occupancy sensor that could help commercial buildings cut their energy costs. Or smaller the power adjustment factor if 0 40 which is suggestive of 40 percent estimated energy savings. Nema lsd 22 2001 r2020 status.

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 addition to. 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. In the example above i used fluorescent highbays to prove a point.

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.
