2  By reviewing lighting energy usage data and the lighting control strategies to reduce lighting consumption, the participant will be able to describe how light control saves energy in commercial buildings.  By reviewing Title commercial building energy code requirements, the participant will be able to determine how light control helps meets those requirements.  Through examination of space-by-space applications, the participant will be able to specify lighting controls to meet the code requirements.  Through examination of the provided real world case study, the participant will be able to describe how they used lighting controls to save energy. Learning Objectives 2

3 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 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 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.

9 Office Building Example – Lighting Energy 9 Time Lighting Power Used 12 midnight 12 noon 1W/sf Annual energy consumption = 4.5 kWh / sf ≈ 3.6 kWh / sf (occ sensing 1 ) ≈ 2.7 kWh / sf (tuning 2 ) ≈ 2.0 kWh / sf (daylighting 3 ) Note: See references at the end of the presentation

10 Office Building Example – Lighting Energy 10 Time Lighting Power Used 12 midnight 12 noon 1W/sf Annual energy consumption = 4.5 kWh / sf ≈ 3.6 kWh / sf (occ sensing 1 ) ≈ 2.7 kWh / sf (tuning 2 ) ≈ 2.0 kWh / sf (daylighting 3 ) ≈ 1.8 kWh / sf (personal ctrl. 4 ) Note: See references at the end of the presentation Save lighting energy of up to 60%

11 State Energy Code Adoption 11 DOE Ruling Oct. 19, 2011: All states must adopt an energy code as stringent as by Oct. 18, 2013.

12 12 Additional HVAC Savings 12 Additional incremental savings in total building energy consumption when lighting energy consumption is reduced.
