Energy Management at SMU
Using wind-generated electricity.
- SMU uses wind-generated electricity in the Embrey Engineering Building.
This means that 3% of the electricity consumed by SMU is from wind, and
the University has joined the EPA Green Power Partnership program.
Central Plant and HVAC Controls Upgrade
- The chilled water side of the Central Plant was completely renovated
with new efficient chillers and cooling towers.
- Every building’s heating and air-conditioning control system were
upgraded to the latest technology.
Exit sign light bulbs
- All exit sign light bulbs have been replaced with LED bulbs that have a
life expectancy of 80 years. This compares to the incandescent bulbs
that lasted only three months. The program paid for itself in a year.
Incandescent to Compact Fluorescent
- Many of the campus 60-100w incandescent lamps were changed to 14-22w
compact fluorescent bulbs.
- Occupancy sensors, which automatically turn off the lights in unoccupied
rooms, have been added to 1,500 classrooms, offices, and conference
Flat-screen computer monitors
- Flat-screen monitors, which consume much less electricity than CRT
monitors, are used throughout the campus. This reduced the amount of
electricity consumed and resulted in an annual savings of about $10,000.
Energy Performance Contract
- The university has entered into an energy performance
contract to upgrade various equipment and entirely paid by the
energy saving. Phase 1 has been completed, which added a new
2400 ton chiller, upgraded about 750,000 square feet of
lighting, added about 80 variable frequency drives and replaced
about 100 motors. Phase 2 will concentrate on water use
reductions (waterless urinals, low flow showers, water closets
and sinks) and upgrade about 200,000 square feet of lighting.
Long Term Electricity Contract
- SMU has contract with Integrys Energy for a flat rate cost for
electricity for 10 years. The contract, although not environmental
significant, will save the university at least $1 million per year.
- SMU is investigating purchasing the entire output of a biomass
generation project in Mesquite, Texas for 9 years, which may save $200K
Excess energy is being recovered from the steam system and used to
generate electricity in the Central Plant. It saves about 500
kilowatts, or $80,000, annually.
Heat recovery devices have been placed on boilers to recover heat
that would normally go into the air and return it back to the water
A “Green Machine” waste-heat generator is being tested at the
Central Plant for the next 6 months, allowing unprecedented
