2. Energy Savings Performance Overview
LWC contracted with Siemens for a
campuswide energy-efficient facility
improvements.
Almost $2 million of improvements
installed, which will generate up
to$228,000 of energy and
maintenance savings annually.

Other: $61,000
4. 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
5. Occupancy Sensors for Lighting
Installed 170 occupancy sensors
Reduces lighting energy consumption by 20-40%
Annual energy savings: $5,800
6. 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
7. 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
8. 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
9. 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
10. 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
11. 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
12. Other
