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.
| kWh | MMBtu | |
| Imported electricity | 13,193,277 Kilowatt-hours | 45,015.46 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 | 2,434.18 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

| Start date | End date | |
| Baseline period | Jan. 1, 1990 | Dec. 31, 1990 |
A brief description of when and why the energy consumption baseline was adopted:
California implemented the legally binding Global Warming Solutions Act (AB32) in 2006, which commits the state to reducing its emissions to 1990 levels by 2020, and by an additional 80 percent by 2050.

CA Title 24-Building Energy Efficiency Standards: https://www.energy.ca.gov/programs-and-topics/programs/building-energy-efficiency-standards
California implemented the legally binding Global Warming Solutions Act (AB32) in 2006, which commits the state to reducing its emissions to 1990 levels by 2020, and by an additional 80 percent by 2050.
The university uses a sophisticated, high-speed, web-based energy management system (EMS), allowing a wider range of control and higher level of efficiency for the Heating, Ventilation, and Air Conditioning (HVAC) system and control of the campus reclaimed water system. The HVAC temperatures are set at 68 degrees in winter and 78 degrees in summer.
Two cooling towers were replaced in the Central Plant, at the end of their service life in 2014, with new, high efficiency cooling towers that provide HVAC for most of the buildings on campus.
A photovoltaic system was installed to support the campus irrigation pump station.
Fume hood exhaust improvements were made on the third floor of Naraghi Hall of Science involving a retrofit of the original, high volume ventilation system to a system that reduces flows through fume hoods to the lowest allowable levels.
The Central Plant MBx was retrofitted to optimize the performance of the campus chilled and hot water distribution systems, and chiller plants, to address operational issues with the goal of reducing energy usage.
Summer and Winter Intercession classes are scheduled to allow shut-down of the HVAC system in some buildings and zones during low-use periods.
