UC Los Angeles Campus & Medical Center Strategic Energy Plan ...

One campus, UC Santa Barbara, has chosen to replace existing HPS pole street lights with new
LED technology. LED technology is currently quite expensive, but has great potential for energy
savings.
8.1.6 Campus Specific Lighting Survey Details
UCLA campus buildings currently have 32W T8 lamps and standard electronic ballasts in nearly
all linear fluorescent fixtures. The campus recently began using 28W T8 lamps as a standard
replacement lamp. This report includes an analysis of retrofitting all 32W T8 fixtures in campus
buildings with 28W T8 lamps and premium efficiency ballasts with low ballast factors. The
analysis is based on the campus’s estimate that there are 600,000 T8 lamps on the campus. Of
these, it is estimated that 10% have already been replaced with 28W T8 lamps.
An alternative to replacing both the lamps and ballasts is to replace only the lamps. This will
achieve a higher light level than the recommended project, but fewer energy savings. A savings
and cost analysis of replacing only the lamps is included in the appendix.
UCLA has installed bi-level stairwell fixtures in two buildings, and plans to replace 600 fixtures
with the bi-level technology. A savings and cost analysis of this project is included.
UCLA has occupancy control in most offices, classrooms, and restrooms on campus. It is
recommended that additional occupancy sensors be installed to cover all offices, classrooms,
and restrooms, in addition to meeting rooms, auditoriums, storage areas, and some library
spaces. Based on a small sampling of campus buildings, it is estimated that 25% of UCLA
buildings do not yet have occupancy sensors. The analysis assumes that occupancy control is
installed on the remaining 25% of the lighting.
According to the UCLA Housing staff, approximately 95% of lighting fixtures in Housing
buildings have 32W T8 fluorescent lamps and standard electronic ballasts. In renovations,
occupancy sensor controls are included in offices, but not in residential rooms. Renovations
also include bi-level stairwell fixtures. Because the campus did not request an analysis, a
lighting retrofit was not analyzed for Housing areas.
There are a few interior areas on campus that are lit with HID fixtures, such as the Wooden
Center and SAC/Men’s Gym, Pauley Pavilion, and the Ackerman Bookstore. Alternatives have
been analyzed and recommended.
All of the parking structures are lit with high pressure sodium (HPS) fixtures, with the exception
of one floor of the Parking Structure 5, which has induction lighting. At the request of the
campus, induction lighting was analyzed as a retrofit for the parking structures.
At the direction of the campus, the lighting analysis of the medical facilities was not included.
8.1.7 Other Projects & Technologies to Consider
Potential Lighting Alternate 1. Integrated Classroom Lighting System
The Integrated Classroom Lighting System (ICLS) has been developed and promoted by the
California Energy Commission’s PIER Program. ICLS combines direct-indirect fluorescent
fixtures with occupancy and daylight sensors, and plug-and-play interconnection cables, to
