A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Creighton University has beenoptimizing energy management systems across the campus, replacing fluorescent lights with LED lighting in parking garages and buildings, retro-commissioning the business center to enhance energy efficiency, insulating piping and mechanical equipment to minimize heat loss, upgrading science labs to improve air conditioning, evaluating building operations and energy performance s for potential efficiency enhancements, implementing a Peak Energy Savings Program to reduce electricity demand and foster an energy conservation culture, replacing bio-safety cabinets with zero-exhaust models, upgrading chilled water valves for better flow control, and recommissioning HVAC and Building Controls at the Champion Center.
A brief description of energy use standards and controls employed by the institution:
State of the art building management systems are used to control temperatures in building spaces/rooms during occupied and unoccupied hours. We have night set backs incorporated for the campus. We also have unoccupied modes set. We also employee a Demand control ventilation on all new installs to limit the amount of outside air that we need to recondition.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
We have upgraded many of the existing lighting to LED's, including such applications as hallways, retail spaces and outdoor pathway lighting. We have a standard to install only new LED's for all project work. LEDs in the Energy Technology department's classroom are powered using a low-voltage transformer.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
There is a passive solar heater on one of our buildings. Two of our buildings have geothermal systems. We also have a solar water heater on a building.
A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
We are working with the Control contractor on building HVAC commissioning.
We undertook a program to replace over a dozen ducted B2 biosafety cabinets with unducted C1 biosafety cabinets, drastically reducing the energy usage of these types of cabinets.
Facilities Management is working with labs to replace traditional -80 freezers with high performance stirling engine freezers.
An ongoing program is replacing steam traps with new, more efficient versions across campus.
