Metric used in scoring for Part 1

Total site energy consumption per unit of EUI-adjusted floor area per degree day, performance year:

27.64 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	81,523,901 Kilowatt-hours	278,159.55 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	336,093.16 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

614,252.71 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

4,772,310 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Jan. 1, 2000	Dec. 31, 2000

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 energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.08 MMBtu per square foot	0.15 MMBtu per square foot
Baseline year	0.13 MMBtu per square foot	0.25 MMBtu per square foot

Metric used in scoring for Part 2

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

39.17

Optional Fields

Documentation 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:

---

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 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 the 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 $18 million in energy efficiency projects on campus.
