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:

Several large lighting projects were completed during FY19 including the Fieldhouse, TSC, CPD, Fine Arts Center, and Old Main. We anticipate approximately 742,854 kWh of savings annually and 553 metric tons reduction of CO2 emissions from these projects completed this past fiscal year. In addition to lighting efficiency upgrades these projects have included control systems incorporating 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.
