Different levels of Energy Conservation Measures (ECMs)
SourceOne A Veolia Energy Company
Quick Payback
• Easy to implement • Examples: LED lighting, motor change-outs, building
envelope, plug load controllers, aerators, BAS optimization, T-stats etc.
Moderate Payback
• Require significant engineering and capital • Examples: BAS installation, VFD’s, chillers, boilers,
fan coil units, CHP plants, etc.
Long Payback
• Facility Improvement Measure (FIM) with little to no energy savings and payback
• Windows, elevators, roof replacement, energy management systems, etc.
