Smart Lighting Initiative Phase 2
SLI Objectives
Reduce Campus electrical lighting energy
consumption 60 percent by 2015
•
2007 as the base year
•
Savings over 15 years to pay for investments
•
Additional benefits
– Leveraging the California Lighting Technology Center and
UC Davis Energy Efficiency Center
– Promoting the campus as a technology and sustainability
leader
– Inspiring Campus ties with the CPUC and PG&E
– Shrinking UC Davis carbon footprint
– Improving lighting quality
– Enhancing safety and security
– Assisting with lighting maintenance program
– Savings from reduced cooling needs
– Taking advantage of available incentives

Lighting Knowledge
Lighting Temperature
•Previous – 3500K
•New – 4100K
Lighting Type:
•LED – Light Emitting Diode
•Fluorescent
Controls:
•Switch – turn lights on/off, dim
•Occupancy Sensor – switch or ceiling
mounted
•Photocell – based on light entering
windows.
Smart Lighting Initiative Phase 2
Lighting Types
EPA –
•LED
•Fluorescent
•Used to replace inefficient parabolic
fixtures
Smart Lighting Initiative Phase 2
Lighting Types
Rebuilds:
•Mostly 1x4 fixtures
•Where retrofit will not fit in 2x4
Smart Lighting Initiative Phase 2
Switch Types
Rocker switch:
•Used in larger spaces
•Where ceiling mounted Occ
sensor is used
On/off - Dimmer
Red LED sensor
indicator light
On / Brighter
Off / Dimmer
Occ Sensor
Single Button Occ switch:
•Used for dimming switching
•Occ Sensor integrated in
switch
Smart Lighting Initiative Phase 2
Switch Types
Scene switch:
•Used in larger spaces /
Conference rooms /
Presentation spaces
•Pre-determined settings
Two Button switch:
•Used for A/B switching
•No dimming associated
Smart Lighting Initiative Phase 2
Occupancy Sensor Types
Ultrasonic Occ Sensor:
•Uses ultrasonic wave to
determine presence
•Used in hallways and spaces
that do not have direct line of
sight
IR window –
programming
Sensor indicators
IR Occ Sensor:
•Uses infrared signal to
determine presence by motion of
heat.
•Used offices and open spaces –
may have multiple units in one
space
Smart Lighting Initiative Phase 2
Troubleshooting
What to look for:
Lighting:
Some lights can take up to
two to three seconds to
respond – Why?
• Switch can take up to .5
seconds to respond.
• Fluorescent lights can take
an additional 2 seconds to
respond due to program
start.
• Fluorescent lights – look
for a quick flicker at the
ends of the fixture – this
indicates that the lamp is
starting – if the lamp does
not light in 2 to 3 seconds,
• Call in and report.
Occupancy sensor:
Two types – Ultrasound
• Ultrasound uses sound
waves to determine
occupancy
• Blue light flashes when
movement is detected in
one of the sound cones
• Provides wider coverage
Occupancy sensor:
- and Infrared
• Uses an IR signal to detect
heat
• Center circle is the sensor
• Red light flashes when
movement is recognized
• Easier to adjust sensitivity.

Troubleshooting
What the….
Why does my light go out
why I’m still there?
• You must make a major motion to
activate the sensor/timer to avoid a
time-out. This is an arm movement
across the sensor area – faster is not
always better.
• On IR, the detector is cone shaped
and best to move perpendicular to
this detector (ie – up and down arm
movement for wall sensor, back and
forth for ceiling sensor.
• Time-out times are set for 20 minutes
– this is a single timer, so the same
time for lights off as for lights on. 30
minutes is maximum as dictated by
CPUC
Who should I call / email?
• Consult the training manual.
The instructions are straight
forward, but there are a few tips
you learned during this session.
• Have your personnel ask
someone who has been to this
training for some help.
• If still operating erratically or not
at all, contact Facilities OM
Customer Service.
Why didn’t my lights get changed?
•Design decision based on lighting
density, space use, existing
controls and capital resources
