OPERATING COST SAVINGS
Lighting controls can reduce lighting system operating costs by eliminating waste. They eliminate waste by helping the  lighting system to place the right amount of light where it’s needed and when it’s needed.
Specifically, an effective controls system can reduce both the amount of power required by the lighting system and amount of time it operates, reducing both sides of the energy equation (Energy = Power x Time). This can translate to a number of economic benefits, including lower energy charges, lower demand charges and, depending on the power provider and controls strategy, advantageous utility rates.
According to the New Buildings Institute, lighting controls can reduce lighting energy consumption by 50% in existing buildings and by at least 35% in new construction.

ENERGY SAVINGS
Depending on the characteristics of the space to be controlled, energy savings as high as 90% can be realized through use of occupancy sensors, according to the U.S. Environmental Protection Agency.
