A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Working through Sustainability Office staff, FM Energy Management has information for Green Teams - information is also included in outreach materials associated with Green Office Certification programs.


A brief description of energy use standards and controls employed by the institution:

Utah has been aggressive keeping up with the latest Energy Codes for construction over time. The state has required all new state-funded buildings to be built in a way that qualifies for LEED silver or higher.

Operationally, new standards have been created for controls optimization and to clarify temperature and humidity requirements by space use. Operational efficiency projects are continuing in the process of applying these standards campus-wide.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

The University of Utah continues to improve its lighting standard for exterior structures and uses LEDs in all new construction and renovation projects where applicable. Buildings, parking structures, walkways, etc. are being switched over to LEDs and are required to adhere to the University’s dark-sky policies that minimize light pollution, and our lighting specialist in Facilities Sustainability & Energy works extensively with project teams to identify opportunities for LED installation.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The Gardner Commons building was recently constructed with a ground source thermal storage system. The loop can exchange energy seasonally and enabled smaller mechanical systems to be used within the building.


A brief description of co-generation employed by the institution:

The UofU has a natural gas combined heat and power (CHP) plant that serves its lower campus area. Facilities Management has created operating guidelines to ensure the plant is operating at peak efficiency (based on demand for campus heat, pricing of NG and electricity, etc.)


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Facilities Sustainability & Energy and the Sustainability Office implemented an Energy Star purchasing requirement for new appliances including a refrigerator/freezer swap. Facilities Management completed a major project that increased the efficiency of the east campus chilled water production and distribution system which included re-commissioning of chilled water systems at numerous buildings served by the plant.
