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 | 6,535,383 Kilowatt-hours | 22,298.73 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 211,395 Kilowatt-hours | 721.28 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 63,267 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
The baseline was chosen as this is a plateau period for building additions.

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Staff attempts to reach out through student clubs, staff meetings and individual education to explain the importance of each person’s role in reducing energy use. The use of marketing materials on bulletin boards and common spaces serves as a resource for the campus community to understand energy consumption practices.
A brief description of energy use standards and controls employed by the institution:
-Temperature comfort zones set to 68 degrees (winter) and 78 degrees (summer)
-All classrooms spaces and most offices are equipped with occupancy and/or vacancy sensors.
-Common spaces are on lighting control panels that can be dimmed or turned off in naturally lite areas or during curtailment events.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED fixtures are used to replace fixtures as needed. The campus has a full scale LED and control upgraded planned, both internally and externally.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Many of the buildings on campus have large windows, these are our only PSH.
A brief description of co-generation employed by the institution:
A fuel cell became operational in December 2015 through PPA. Waste heat is used to preheat boiler water and power absorption chiller to supplement cooling. The campus pays for the electricity produces and natural gas to supply fuel cell.
