  • According to the New Buildings Institute, lighting controls can reduce lighting energy use by 50 percent in existing buildings and by at least 35 percent in new construction
  • Daylight dimming controls can reduce lighting energy use by 40 percent or more and are a means of reducing peak loads
  • A year-long study of light fixtures that integrated occupancy sensors, daylight dimming and dimming control produced 42-47 percent energy savings
  • Use of lighting controls reduces the amount of power used during the peak demand period by automatically dimming lights or turning them off when they are not needed
  • Dimming or shutting off electric lights reduces the number of hours per year that the lights are on, extending the life of the bulbs and reducing energy costs
  • By reducing lighting use, internal heat gains are reduced which allows for reduced HVAC system size and a reduction in the building's cooling needs
