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 | 37,048 MMBtu | 37,773 MMBtu |
| Electricity from on-site renewables | 0 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) | 44,935 MMBtu | 51,718 MMBtu |
| Total | 81,983 MMBtu | 89,491 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | Jan. 1, 2019 | Dec. 31, 2019 |
| Baseline Year | Jan. 30, 2008 | Dec. 31, 2008 |

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):
Based on lessons learned from our first RCx, we are prioritizing building-level energy meters, which will allow us to launch internal performance competitions, populate dashboards, and engage in real-time conversation about energy use. Meters have been included as base requirements in recent major renovations, and are scheduled to be installed in student residence halls.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The institution's building temperature standards are maintained by the Department of Facilities at 68-72'F (heating) and 74-78'F (cooling). Lighting controls with occupancy sensors have been included as base requirements in recent major renovations.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Taking advantage of utility incentives, the College has recently completed a campus-wide replacement of fluorescent lamps with LEDs.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
(none)
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
(none)
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):
A comprehensive retrocommissioning study (RCx) was completed in 2020 of our largest campus building (Crafton Athletic Center @ 95,739 ft2). The study provided a building/systems description, conducted a utility analysis, assessed energy efficiency measures, and made recommendations going forward. The study "found a number of significant opportunities to reduce energy consumption with minimal investment"; every recommendation with less than a one-year payback has been implemented.
