A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Staff attempts to reach out through student clubs, staff meetings and individual education to explain the importance of each person’s role in reducing energy use. The use of marketing materials on bulletin boards and common spaces serves as a resource for the campus community to understand energy consumption practices.
A brief description of energy use standards and controls employed by the institution:
-Temperature comfort zones set to 68 degrees (winter) and 78 degrees (summer)
-All classrooms spaces and most offices are equipped with occupancy and/or vacancy sensors.
-Common spaces are on lighting control panels that can be dimmed or turned off in naturally lite areas or during curtailment events.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED fixtures are used to replace fixtures as needed. The campus has a full scale LED and control upgraded planned, both internally and externally.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Many of the buildings on campus have large windows, these are our only PSH.
A brief description of co-generation employed by the institution:
A fuel cell became operational in December 2015 through PPA. Waste heat is used to preheat boiler water and power absorption chiller to supplement cooling. The campus pays for the electricity produces and natural gas to supply fuel cell.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Data source(s) and notes about the submission:
Note: There is a discrepancy with our baseline reporting and current reporting of Stationary fuels used on-site to generate electricity and/or thermal energy. In 2015 a fuel cell was installed which runs completely off of natural gas, roughly quadrupling our natural gas consumption. Therefore, you see a jump from our baseline year, which is reporting zero, to our current year reporting due to this installation.
