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

2.3 Campus Overview
University of California, Los Angeles was founded in 1919 and opened its medical center in
1955. The campus currently has approximately 27,000 undergraduate and 11,500 graduate
students, and over 4,000 faculty members. UCLA is one of the most prestigious campuses in
the University of California system with 174 buildings spread across 419 acres.
The majority of the buildings audited for at UCLA are old and historic. Chilled water and heating
hot water is supplied from campus central plant except for few buildings which have localized
chillers and hydronic boilers. Buildings audited included residential, educational, athletic,
medical and research facilities. Residential buildings use water source heat pumps and split air
conditioning units. A majority of the laboratory buildings have constant volume fume hoods and
dual duct mixing boxes for zone control. Molecular Science Building, a laboratory building has
variable air volume fume hoods with VAV box for zone control. Animal research facilities also
have constant volume terminal boxes with higher air change rate (ACH @ 15). Buildings employ
either direct digital controls (DDC) or pneumatic controls to control and monitor major
mechanical equipment and for zone control. Air handling units serving buildings vary from and
include constant volume dual duct air handlers, variable air volume air handlers, and multi zone
units. Some of VAV AHU’s have inlet guides vanes to control supply air flow. All major
mechanical equipment in building is controlled and scheduled through campus energy
management system (Siemens Apogee).
2.4 Central Plant
The central plant at UCLA serves the main campus in Westwood. It is based on a cogeneration
system which includes two GE LM 1600 gas turbines, each with a rating of 14.5 MW, two high
pressure (600 psig) heat recovery steam generators with duct burners, and an
induction/extraction condensing steam turbine, for a total generation capacity of about 40 MW.
Power is generated in parallel with LADWP, providing most of the campus electric load, which
peaks at about 50 MW. The facility also houses two backpressure steam turbine centrifugal
chillers rated at 5,300 tons, four single stage absorption chillers, and an electric centrifugal
chiller rated at 5,300 tons. Steam is provided to the campus at 100 psig. A portion of the gas
used to operate this plant is recovered from the Mountain Gate Landfill.
2.5 Strategic Energy Plan Buildings
The following 41 buildings were investigated as part of this SEP effort, and were selected using
the criteria described above. The total gross area of the SEP buildings represents
approximately 6 million square feet, or 29% of the campus gross area (exclusive of parking). An
additional 18 buildings were identified as appropriate to extrapolate findings to directly,
incorporating approximately 8.7 million square feet (or 42%) of total building area into this
report.
