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 | 137,132,845 Kilowatt-hours | 467,897.27 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
This baseline was adopted this year, an update from the previous 2006 baseline, as 2019 is much more reflective of OSU's campus as it currently exists. New buildings have been built, updated infrastructure and many energy-efficient changes have been made since 2006.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The OSU Energy Management Program is a behavior-based program designed to reduce energy consumption on each of its five (5) branch campuses: OSU-Stillwater, OSU-Oklahoma City, OSU-Tulsa, and the Center for Health Sciences, and OSU-IT in Okmulgee. Energy managers at each of the branch campuses work with faculty, staff, and students to identify and implement ways to reduce utility usage, per OSU Energy Guidelines. Since the program began in July 2007, the OSU system has saved nearly $66 million in energy costs, and over $53 million has been saved by OSU-Stillwater.
A brief description of energy use standards and controls employed by the institution:
1.01 The OSU/A&M Board of Regents embraces energy conservation and endorses the concept that it is everyone's responsibility to ensure every reasonable effort is made to conserve energy and natural resources while exercising sound financial management.
1.02 The importance of adopting energy management and conservation policy is recognized in order to administer the program. The implementation of this policy will be the joint responsibility of the Board of Regents, campus administration, faculty, staff, students, and Energy Education, Inc (EEI). Success is based on cooperation at all levels.
2.01 Each campus will maintain accurate records of energy consumption and cost and will provide verifiable performance information to the Board of Regents and administrations at the various institutions in the OSU System on the goals and progress of the energy conservation program.
2.02 Each campus administrator will be accountable for energy management on his/her campus, with energy audits being conducted and feedback provided by the Energy Educator/Managers.
2.03 To ensure the overall success of the energy management program, the following specific areas of emphasis will be adopted:
A. EEI will administer its energy conservation and management program, primarily through the campus Energy Education/Managers and administrators.
B. The Board expects all personnel at each campus to make a positive contribution to maximize energy conservation and produce real energy savings.
C. "Energy Guidelines" will be adopted that define the rules for implementation of the energy program.
2.04 To promote a safe, healthy learning environment and to complement the energy management program, each campus shall review and adhere to the preventive maintenance and monitoring plan administered by the campus physical plant for its facilities and systems, including HVAC, building envelope, and moisture management.

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. In addition, several ground source heat pumps are used on OSU's campus.
