A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Since 2010, the University has implemented a number of programs to help educate the community on energy consumption as part of the partnership with our local utility, SDG&E. Intentional outreach activities, including USD's Green Office Certification program, Vampire Energy Slayers initiative, and campus workshops about reducing energy consumption, contribute to this effort. USD also maintains a small program focused on reporting energy use at a room level to students living in one set of residence halls in the Alcala Vistas (the only individually metered units on campus). Efforts in this program have seen consumption drop by as much as 33% in the past competitions.
A brief description of energy use standards and controls employed by the institution:
More than 50% of the buildings on campus have HVAC services controlled by the Siemens building management system, which is currently being upgraded to the Desigo system. The chillers, and other plant can be controlled with time schedules, enabling AC and cooling/ heating to be turned down/ off outside hours. In 2018,the university created and implemented Temperature Standards that established temperature ranges and occupancy hours for campus buildings.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lights are used for many outdoor safety and landscaping lights. They have also been deployed in newly-constructed buildings, including Mother Rosalie Hall (SOLES). Retrofits of older buildings have also begun, including in the Facilities Management complex, Copley Library, the Legal Research Center, and the SOLES parking garage. A comprehensive list of buildings, fixtures and potential savings from LED upgrades was compiled in 2018 as part of a Level 1 energy audit. This information will be used to inform the energy master plan that USD is creating to achieve climate neutrality by 2035.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
As part of the SDG&E Partnership Program the university prioritizes this work. Since FY2010, USD has seen overall electrical consumption drop more than 8,700,000 kWh annually, in part due to retrocommissioning and efficiency programs. Specific tactics that have been deployed include HVAC tune-ups, installation of variable frequency drives, and replacement of pneumatic actuators with electric versions.
