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 | 85,951,883 Kilowatt-hours | 293,267.82 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 | 573,500 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
2005 is the most recent year in which we have comprehensive energy data.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Various programs target behavior change on a small scale. An updated list is covered in the Energy category of our blog: https://blogs.oregonstate.edu/ecologue/category/energy/
A brief description of energy use standards and controls employed by the institution:
Most OSU buildings have temperatures regulated by centralized building automation systems (BAS). The BASs adjust temperature depending on hours of occupancy for the specific building and, in some spaces, based on actual occupancy using interior sensors.
Buildings not on BAS systems also typically have some sort of timing for HVAC control.
Buildings not on BAS systems also typically have some sort of timing for HVAC control.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lamps are currently being used in hundreds of locations on campus, usually replacing incandescent lamps, and most recently, replacing some fluorescent as well. New construction has implemented LED lighting technology for interior and exterior application.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of co-generation employed by the institution:
At the LEED Platinum Energy Center, electricity is generated in a gas turbine (fueled by natural gas), which then creates high quality waste heat. This waste heat is used to make steam for campus. The Energy Center provides about 40% of the electricity for campus. https://fa.oregonstate.edu/sustainability/operations/green-building/completed-construction
