A brief description of when and why the energy consumption baseline was adopted:
It was chosen to align with our GHG baseline because of the direct link between energy use and GHG emissions. This aligns with the UC policy on sustainability practices that set a campus-wide goal of reducing GHG emissions to 2000 levels by 2014.
Source-site ratio for imported electricity:
3.14
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.07 MMBtu per square foot | 0.14 MMBtu per square foot |
| Baseline year | 0.10 MMBtu per square foot | 0.20 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:
30.71

A brief description of energy use standards and controls employed by the institution:
The University of California, Santa Barbara's campus building automation system, Johnson Controls Metasys, monitors mechanical, electrical, and utility metering systems in most large buildings on campus. There are thousands of points throughout the buildings measuring the environmental conditions, utility consumption, and operational status of various mechanical systems. UCSB Facilities Management staff use sequences of operation, including occupancy and schedule-based thermal controls.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED technology is in place in many applications at UCSB, including indoor and roadway lighting, traffic signals, and exit signs. UCSB has installed many advanced lighting control systems to optimize controllability of LED retrofits in corridors, open offices and gymnasiums.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Passive solar heating is a strategy implemented in all new buildings on campus. The climate at UCSB is such that mechanical ventilation is very rarely used in perimeter office spaces or in residential living spaces.
A brief description of co-generation employed by the institution:
None
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The campus has robust building recommissioning and retrofit programs. UCSB is an active participant in the Statewide Energy Partnership program, which is a collaboration between the University of California, California State University, and California Investor Owned Utilities. Since the program’s inception in 2006, UCSB has invested over $20 million in energy efficiency projects on campus.
