Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 85,509 MMBtu | 111,164 MMBtu |
| Electricity from on-site renewables | 6,503 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 58,641 MMBtu | 110,184 MMBtu |
| Total | 150,653 MMBtu | 221,348 MMBtu |

| Baseline Year | July 1, 2009 | June 30, 2010 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The energy baseline is consistent with USD's Climate Action Plan.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
Since 2010, the University has implemented a number of programs to help educate the community on energy consumption as part of our on-going partnership with our local utility, SDG&E. Intentional outreach activities, including USD's Green Office Certification and campus workshops about reducing energy consumption, contribute to this effort. Intentional training for Resident Assistants and student who lead orientation activities aim to educate students about the impacts of energy consumption. USD also has a small program focused on reporting energy use at a room level to students living in the Alcala Vistas. Efforts in this program have shown to reduce consumption by as much as 33% in the past.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
More than 50% of the buildings on campus have HVAC services controlled by a Siemens building management system. The chillers, and other plant can be controlled with time schedules, enabling AC and cooling/ heating to be turned down/ off outside hours.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lights are used for outdoor lights and landscaping lights. They are also used in several buildings, examples being Mother Roselie Hall (SOLES), and the Facilities Management office.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
N/A
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
N/A
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
As part of the SDG&E Partnership Program the university prioritizes this work. Since 2009, USD has over 10,000,000 kWh in annual savings from retrocommissioning and efficiency programs.
