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 University has a goal of reducing the EUI by 2% annually. We utilize the eSight Energy Management System to monitor building performance and
investigate deviations from the standard of operation of the HVAC equipment. All eSight buildings are checked on three times/day, Monday thru Friday to
maintain vigilance over building operations.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All new construction and renovation work includes LED luminaires, and any failed luminaire is replaced with an LED equipped equivalent.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A small geothermal system is installed at the Administration Support building.
A brief description of co-generation employed by the institution:
Lubbock Power & Light operates a sub-station adjacent to the campus that sends steam to the CHACP at no charge. The operation of the sub-station is
intermittent, and has decreased over the last two years.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Create a five-year plan for energy efficiency projects.
