A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

none


A brief description of energy use standards and controls employed by the institution:

We have installed energy management systems in buildings which represent 89% of our total campus building space. These systems are used in conjunction with individual building occupancy schedules to automatically turn off the HVAC systems off during unoccupied periods and perform setback of the space temperatures to 60 degrees in the winter and 80 degrees in the summer.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

We have installed LED lighting in many locations, including parking structures and our athletics complex


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:

None


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Retrocommissioning happens across campus, and LCA is used to evaluate equipment efficiency. The campus green fund often is used to support procurement of more efficient equipment.
