A brief description of when and why the energy consumption baseline was adopted:
USU signed the ACUPCC in 2007, so we use the fiscal year 2008 as the baseline to evaluate progress from the time USU became a signatory to the Commitment.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.11 MMBtu / GSF | 0.13 MMBtu / GSF |
| Baseline year | 0.13 MMBtu / GSF | 0.18 MMBtu / GSF |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
USU uses two different building management systems to control the temperatures in all of the buildings on central campus. StruxureWare from Schneider Electric and Metasys from Johnson Controls are used to control everything from temperature set points, time-of-day schedules, occupancy requirements, fume hood operation, outside air mixtures, and exhaust fan operation. In most of the buildings, USU can control these factors down to the room level to provide optimal comfort and energy management control.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Since FY 2019, almost all lamps on campuses statewide have been replaced with LEDs. In addition to lighting efficiency upgrades, some projects also include occupancy sensors and time clocks.
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:
The USU cogeneration plant contains three Babcock and Wilcox boilers with a capacity of 220,000 lbs/hr of steam to heat the campus. It also contains three York chillers with the capacity to produce a total of 4500 tons of cooling. One Solar gas turbine generator unit with a heat recovery has the capacity to produce 4.5 MW of electrical power and up to 50,000 lbs/hr of steam from the heat recovery unit.

Additional documentation to support the submission:
Our square footage numbers have greatly increased from the baseline. Within the last 13 years, we have built new buildings, where landscape once stood. We have also had many buildings donated, as well as purchased quite a bit of property over the years. Some of the difference can also be attributed to the way we maintain and update our records as well. We are constantly improving and updating every square foot that USU owns, therefore our data is always becoming more and more accurate.
