A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
The energy management system at the campus heating/cooling plant directs temperature regulation from the distribution point. Heating/cooling run time of the air handler are based on occupancy hours. Night set-back.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting is being used in track lighting and display cabinets in the University Union, Kress Events Center, Laboratory Sciences, Instructional Services, and Weidner Center for the Performing Arts. LED lighting has also been installed in all exterior path lighting (245 path lights) as well as in the University Union's Cloud Commons dining facility. Working on converting parking lot & street lights to LEDs (60 fixtures of 330 will be swapped out in 2022). The Mary Ann Cofrin Hall renovation incorporated LED lighting into all the classrooms.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of co-generation employed by the institution:
N/A
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
All appliances are Energy Star.

Additional documentation to support the submission:
The electricity and natural gas data (and sq ft) is for the academic buildings and auxillary buildings on the main campus. Still working on acquiring data for housing, which is owned and accounted for separately. Unsure why imported steam/hot water/chilled water was listed previously. According to our heating plant superintentendent, we generate our own steam and chilled water through our purchased electricity and natural gas - we do not purchase it from another party. This error has been corrected in this report.
