Additional Benefits
- Reduces motor wear and tear while providing a soft start.
- Provides a soft start that reduces mechanical and electrical stress on motor components during startup.
- Leads to less maintenance and repair costs and more efficient motor operation over time.
Program Eligibility Criteria
- Installation of a VFD in commercial settings where a VFD was not previously installed.
- Applications include: AHU supply fans, hot and chilled water distribution pumps, and cooling tower fans.
- Not applicable to compressor controls.
- Supply fans must not have variable pitch blades.
- Motor horsepower less than or equal to 100 hp does not require custom energy savings measurement or data logging. Motor horsepower greater than 100 hp does require custom energy savings measurement.
- New construction and equipment used for process loads are excluded.
Necessary Information for Project Savings Calculations
- Application type (e.g., AHU supply fan, hot water pump, chilled water pump)
- Motor horsepower (include a photo of the motor nameplate showing horsepower)
- AHU only: Baseline part load control type (e.g., outlet damper, inlet damper, inlet guide vane, constant volume/no control)
- Climate zone or county
- Building type
