Learning Objectives 2

Why is Lighting Control Important? 33 Buildings consume 39% of total U.S. primary energy Lights use the most energy in commercial buildings Source: U.S. DOE

4 Light Control Strategies Occupancy/Vacancy Sensing: Automatically turning lights off when people vacate the space. Daylight Harvesting: Automatically adjust light levels based on the amount of daylight in the space. Multi-level Lighting/Dimming: Proving users one or more light levels than full-on and full-off. Scheduling: Lights automatically turn off or are dimmed at certain times of the day or based on sunrise or sunset. High-End Tuning: Set target light level based on occupant requirements in the space.

5 Controllable Window Shades: Allows users to control daylight for reduced solar heat gain and glare. Personal Light Control: Allow users in the space to select the correct light levels for the desired task. Demand Response: Reducing lighting load at times of peak electricity pricing. Plug-load Control: Automatically turning task lighting and other plug loads off when they are not needed. Light Control Strategies System Integration: Enabling multiple systems to share information and control each other to minimize product installed and maximize overall system performance.
