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 | 93,035,841 Kilowatt-hours | 317,438.29 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):

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Energy Assessments
Nicor (natural gas provider) and ComEd (electricity provider) have performed energy assessments (as they relate to their specific commodity) on a number of university buildings. These energy assessments identify, evaluate, and prioritize potential energy-saving projects.
An outside contractor performed a facility conditions and assessment needs assessment on a subset of the campus buildings. The assessment identified various projects intended to bring the building back to peak performance based on its usage type. The assessment also included an ASHRAE Level I Audit.
The identified energy conservation measures from the various assessment have not yet been implemented; however, the intention is to compile all the opportunities and prepare an implementation schedule for the realistic projects based on available funds.
Submetering
A pilot project is underway to implement an energy management system and install utility submeters on a small subset of buildings. The meters will allow us to understand the building performance on a more granular level. The goal is to eventually install submeters on all buildings to gain a better understanding of overall campus performance.
