Learning Objectives
 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 24 2013 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.

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

Light Control Strategies
Scheduling: Lights automatically turn off or are dimmed at
certain times of the day or based on sunrise or sunset.
Occupancy/Vacancy Sensing: Automatically turning lights
off when people vacate the space.
Multi-level Lighting/Dimming: Proving users one or more
light levels than full-on and full-off.
Daylight Harvesting: Automatically adjust light levels
based on the amount of daylight in the space.
High-End Tuning: Set target light level based on occupant
requirements in the space.
4
Light Control Strategies
Personal Light Control: Allow users in the space to
select the correct light levels for the desired task.
Controllable Window Shades: Allows users to control
daylight for reduced solar heat gain and glare.
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.
System Integration: Enabling multiple systems to share
information and control each other to minimize product
installed and maximize overall system performance.

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