Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 313,817.60 MMBtu 278,170.26 MMBtu
Electricity from on-site renewables 3,193.77 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 327,033.80 MMBtu 336,093.16 MMBtu
Total 644,045.17 MMBtu 614,263.42 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2016 Dec. 31, 2016
Baseline Year Jan. 1, 2000 Dec. 31, 2000

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

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.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 8,327,571.50 Gross Square Feet 4,772,310 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.08 MMBtu / GSF 0.13 MMBtu / GSF
Source energy 0.16 MMBtu / GSF 0.25 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 1,828 Degree-Days (°F)
Cooling degree days 169 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 765,355 Square Feet
Healthcare space 14,852 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
9,926,891.50 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
32.49 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

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 hundreds of points throughout the buildings measuring the environmental conditions, utility consumption, and operational status of various mechanical systems. UCSB Energy Services 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, e.g. combined heat and power (CHP):


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

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 $15 million in energy efficiency projects on campus.
