What’s Your Plan?

44% of a commercial building’s energy consumption is attributed to its HVAC systems. It is important to properly maintain these assets to reduce energy use and reduce total cost of ownership.

Maintenance Approaches Currently Implemented in Commercial Buildings (2000 US DOE Study)

  • 55% – Reactive Maintenance
    • Most people do almost nothing…
    • Little if any maintenance is done (usually filter changes only)
    • Repair or replacement is done when components fail
    • This is the MOST EXPENSIVE approach in terms of total cost of ownership:
      • About $18 per compressor horsepower per year
  • 31% – Planned Maintenance 
    • Checklist of activities
    • May be either time or cycle based
    • Often follows manufacturer’s recommendations
    • This is a good option, helping reduce total cost of ownership:
      • About $13 per compressor horsepower per year
  • 12% – Predictive Maintenance
    • Relies on tests and measurements to “predict” failure and act beforehand
    • Measure Amp Draw
    • Thermal Imaging
    • Vibration analysis
    • Mega Ohm measurements of motors
    • Eddy Current study
    • Oil analysis
    • Air flow and/or static pressure measurements
    • This is the best option, helping reduce total cost of ownership:
      • About $9 per compressor horsepower per year (the best bang for your buck)
  • 2% – Other (Reliability Centered)
    • Custom-tailored maintenance which can include advance replacement (equipment and environment-specific)
      • About $6 per compressor horsepower per year

That’s right – it costs more to do nothing than any other method of maintaining your equipment.
