Maintenance Efforts


  1. Design set point for cooling is 75 degrees. Design set point for heating is 72 degrees.
  2. Widen the delta "t" for on and off times to 3°. Created less anticipation between parameters of thermostatic controls to reduce waste, while maintaining humidity controls.
  3. Installed Celestial timer on perimeter and applicable interior lighting to extinguish lamps according to season and daylight savings time. (and not operate during daylight fog)
  4. Implemented P.M's to clean coils at least twice a year or as needed. Fund preventative maintenance programs to maximize effective operations of equipment to minimize outages, disruption of services, outages, and operations costs.
  5. Remodeled Facilities Services/PCI building removing inefficient HVAC equipment and upgrading electrical equipment. By balancing phases effectively we reduced demand consumption.
  6. Security personnel extinguish lamps in offices and classrooms each night before locking buildings. Convenience lamps should not operate after offices are closed.
  7. Installed electronic flush valves on all fixtures to eliminate waste of water and improve hygiene.
  8. Installed "stand-alone" HVAC units that augment current air conditioning in information systems equipment areas, and to provide refrigeration when HVAC systems are disabled every evening. Eliminating the necessity to operate large chillers for these small areas. (This also supports lengthening the life of equipment by reducing heat and stress to electronic and electric components.)
  9. Changed out all T-12 fluorescent lamps and ballasts to more efficient T-8 lamps and electronic ballasts.
  10. Installed CO2 sensors to accurately monitor CO2 levels in the buildings, permitting us to reduce the volume of outside air, reducing the necessity to operate HVAC equipment.
  11. Took advantage of the "cost-free" preliminary energy audits from the State Energy Conservation Office (SECO). We performed these at all three campuses. We implemented all recommendations that showed a reasonable payback, and are scheduling others with longer return of investments, such as boiler change out. Boiler was tested again this year and found to be operating effectively. With a 56 year pay back, we will not change out the boiler.
  12. An alternate work schedule has been implemented for summer months and is being discussed for other periods to avoid increased peak consumption.
  13. Made some adjustments to custodial schedules to take advantage of KW demand savings in electrical expenditures.
  14. Operations and maintenance training to ensure maintenance personnel are adequately equipped to repair drives and VAV units saving maintenance and operations dollars.
  15. Analyze utility use and distribution of utilities to evaluate operating efficiencies and help identify opportunities for reducing energy and maintenance costs. Verify utility billing to ensure charges are correct and usages are not out of the ordinary.
  16. Promote energy conservation through training and awareness programs.
  17. Evaluate and continue to recommend designs for campus facility renovation and new construction projects to help ensure reliable, energy efficient, and user friendly facilities.
  18. Conscientious consideration of purchase and re-lamping of perimeter lamps to prevent "light pollution"
  19. Limit vehicle and identified equipment on ozone days to limit our generation of ozone.
  20. Upgraded the "energy management control system" to provide web based, password protected, access to environmental air conditioning controls. This permits designated employees to access temperatures and settings from off-site and to reduce usage of buildings HVAC systems when buildings are unoccupied.
  21. Tinted windows in large MPR room to lessen the addition of radiant heat that would need to be removed by HVAC system.
  22. Changed out the chiller on the West building and installed an energy efficient model lessening operating costs and utility bills.
  23. Wrapped water heaters to improve efficiency.
  24. Inefficient space heaters were removed, and stricter rules on space heaters were implemented.
  25. Turn boiler off in West building during summer months.
  26. Purchase green chemicals to clean coils on HVAC.
  27. Disable air conditioning in every building each evening after 11:00 p.m. Enable HVAC at 5:00 a.m. Disable HVAC to select buildings on weekends. Disable HVAC systems during holidays, and breaks when buildings are unoccupied.
  28. Extinguish select parking lot lamps after 12:00 p.m., maintaining essential security and safety but eliminating wasteful unnecessary energy consumption.
  29. Added additional VAV's in the West building to more efficiently distribute conditioned air increasing comfort and reducing waste of energy dollars.
  30. Added Totah building to Energy Management system, allowing scheduling of HVAC to save energy.
  31. Adjust set point on air handlers to use cooler outside air when temperatures permit.
  32. Recycled 275 gallons of crushed bulbs, to eliminate the introduction of mercury into the landfills. At this writing, we are one of few universities following these guidelines.
  33. We maintain a spreadsheet of utility expenditures and usage quantities to assist in monitoring our usages in comparison to previous years and current months, quickly recognizing increases quantities and costs.
  34. Fleet efforts
    1. We car pool whenever possible.
    2. We are currently reviewing green vehicles for purchase.
      Alternative Fuel Vehicles (AFVs)
    3. We maintain vehicles in top shape to maintain good air quality, lowering operating costs, and lengthening vehicle service life.
