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 | 133,759,160 Kilowatt-hours | 456,386.25 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 | 638,198 MMBtu |
| Imported steam, hot water, and/or chilled water | 383,398.50 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The OSU Energy Management Program employs behavior-based energy management techniques to engage all staff, faculty and students in the University's goal to continue to lower its energy usage. Outreach and education efforts include presentations, tours, training, office reminder notes, contests, quizzes, email blasts, social media updates, tabling, and special events
A brief description of energy use standards and controls employed by the institution:
We use a building automation system to schedule HVAC run times in most general University buildings. The University has included both occupied and unoccupied temperature ranges for building temperatures within our energy management guidelines. In many labs, occupancy sensors are used to control HVAC and air flow rates so that life safety needs are met while maximizing energy efficiency.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Lighting is being replaced where possible with LED fixtures. The Lutron Vive control system has also been implemented in four buildings with expectations to introduce in various facilities across campus. Outdoor LED lighting has been installed in most outdoor fixtures.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Passive solar heating is employed on campus in these buildings: NRC atrium, ATRC atrium, the Colvin Annex, Architecture building south hallways, and the Student Union atrium.
