This field evaluation seeks to better understand energy savings and economic viability of switched reluctance motors in commercial and industrial HVAC applications in the ComEd service territory.


This field evaluation of switched reluctance motors (SRMs) targets the HVAC systems of non-residential customers. The project team will install SRMs in the rooftop units of selected customer sites, then analyze the energy savings and operating characteristics of each retrofitted motor. Data from both pre- and post-installation operating periods will be weather-normalized and extrapolated to a typical year to estimate annual energy savings.

Additionally, the project team will conduct market research to understand ComEd territory building stock with rooftop units and applicable motors. The team will then extrapolate the estimated annual energy savings to the most common building and system types in ComEd territory to estimate the total energy-saving potential.
