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 | 238,796,440 Kilowatt-hours | 814,773.45 MMBtu |
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UC Davis buildings also have a TherMOOstat and TherMOOfan. The Energy Conservation Office built the TherMOOstat so that students, faculty and staff can let the energy conservation team know how they think the rooms feel on campus. It can be used for any building on the main campus, as often as any user likes. With the comfort feedback that is sent back to the team, it crowdsources indoor comfort and gives everyone the opportunity to contribute to comfort and energy savings. The TherMOOfan is another opportunity presented by the Energy Conservation Office to improve energy efficiency and campus comfort. To accomplish both in large classrooms, high volume, low-speed (HVLS) ceiling fans have been incorporated. HVLS fans can circulate a high volume of air throughout a large space efficiently, thus reducing the need for heating and cooling. The HVLS fan also provides comfort, as classrooms can maintain a more consistent temperature. To take a step further, the UC Davis Energy Conservation Office has added a code to the fans to turn off or on based on expected occupancy in the room, and to set a default speed in rooms when no votes are received (through TherMOOstat). The code also takes into account the outside air temperature, so when a student first walks into the classroom, the fans will operate at optimal speed.
The UC Davis Office of Sustainability offers a Green Workplace certification program that teaches participants how to green their actions and workspaces (offices, labs, and field work). Energy conservation and efficiency practices are part of this program. In addition, the Office of Sustainability offers the Aggie Green Pledge program, a personal sustainability take-action program that includes energy conservation and efficiency pledges.

A brief description of energy use standards and controls employed by the institution:
The Energy Conservation Office is also proactive in reducing energy waste on holidays. By leveraging the campus's complex digital building control system, our engineers implement new holiday schedules and temperature setpoints for building heating, ventilation, and air conditioning (HVAC) systems. For example, during the holidays, some buildings are left completely vacant, which means they don't need their temperatures controlled as tightly. Therefore, temperature settings in these buildings are relaxed significantly during the holidays. The relaxed temperature settings also prevent long warm-up or cool-down times after the holidays, meaning shorter times for a building to return to normal operations after the holidays.
