Other: $61,000
Energy Efficient Lighting
Installed:
8,304 fluorescent lamps for interior lighting
3,047 electronic ballasts
Reduces lighting energy consumption by 15%
Annual energy savings: $39,000
Occupancy Sensors for Lighting
Installed 170 occupancy sensors
Reduces lighting energy consumption by 20-40%
Annual energy savings: $5,800
Building Controls for HVAC
Installed networkable building control systems for Heating, Ventilating, and Air-Conditioning (HVAC) equipment in eight buildings
Installed programmable thermostats in 14 additional buildings
Will allow for the implementation of various energy management strategies
Control of fume hoods in laboratory spaces
Annual energy savings: $67,500
Variable Frequency Drives
Installed 17 variable frequency drives across campus. Locations include Lilly and Richardson Halls; Fugitte Science Center; Holloway Health & Wellness Center; Turner Leadership Center; Slider Humanities Center
Variable frequency drives optimally control pump motors and fan motors at their most efficient operating point
Typical applications are hot water and chilled water pumps for heating and cooling and supply and exhaust fans for ventilation
Annual energy savings: $8,400
Low-Flow Flush Valves
Modified 295 toilet flush valves and 70 urinal flush valves to optimize the flush sequence and eliminate unnecessary water consumption.
Reduces water consumption in toilets by an average of 30%
Annual energy savings: $16,000
Low-Flow Shower Heads
Replaced 291 shower heads with low-flow showerheads
Reduces hot and cold water consumption for showering by an average of 30%
Annual energy savings: $13,800
Low-Flow Faucet Aerators
Replaced 573 faucet aerators with low-flow, pressure independent aerators
Reduces water consumption at sinks by an average of 50%
Annual energy savings: $9,000
Power Management Software for Campus Computers
Installed on 780 campus computers
Provides IT energy management of networked computers
Reduces electric consumption
Annual energy savings: $6,000
Other
Installed energy-efficient windows in V.P. Henry Auditorium and Everett Building
Negotiated a more favorable rate structure for several buildings and athletic field lighting
Moved Cranmer Dining & Conference Center water heating from electric to less costly gas
Installed attic insulation in the L.R. McDonald Building, Goodhue Academic Center and Everett Building
Annual energy savings: $61,000
Work will qualify for more than $20,000 in rebates from the Kentucky Utilities Co.
