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 | 199,282.77 MMBtu | 186,681 MMBtu |
| Electricity from on-site renewables | 1 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 14,717 MMBtu | 10,522 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 313,681 MMBtu | 263,673 MMBtu |
| Total | 527,681.77 MMBtu | 460,876 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |

| Baseline Year | July 1, 2005 | June 29, 2006 |
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):
Baseline was selected when the university first started reporting and was chosen as a reasonable starting point
Gross floor area of building space:

Optional Fields
---
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):
Students learn about individual behavior changes in a class called Sustainability As A Lifestyle. They also learn about best practices in housing during the energy competitions, and throughout the year at various sustainability education events.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
University uses a BMS (Building Management System) for controlling startup, shutdown, setback, occupied and non-occupied temperature set points.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university has been researching and installing LED lighting for the past 5 years. To date we have installed LEDs into several buildings, some tied to motion sensors. For exterior lighting the university has invested over .5 million dollars into installing over 800 LEDs for parking ramps, lots and street lighting.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar panels on the roof of an athletic building capture solar energy to help heat the water source in the locker rooms.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---
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):
Recommissioning is done on a case by case basis. It is done by troubleshooting mainly and is not a stand-alone program. However the university has recommissioned some buildings by a third party to provide some energy conservation measures.
