This research project examines the market readiness of the recently developed Fan Energy Index and identifies how to incorporate this index into the ComEd Energy Efficiency portfolio.
The commonly used Fan Efficiency Grade (FEG) metric defines a fan’s efficiency at a rated condition. However, the condition a fan is rated for is rarely its actual application. As a result, fan performance deviates greatly based on improper sizing, operating pressure and operating speed.
The Fan Energy Index (FEI), developed by the Air Movement and Control Association (AMCA), allows for the comparison of different fans at application-specific operating conditions. This research will quantify the energy savings potential of using FEI across a variety of sectors, fan types, fan speeds, drive types and fan powers. Additionally, the project team will conduct interviews with manufacturers, contractors, designers, building owners and facility operators to understand potential barriers to widespread adoption of the FEI and high-efficiency fans.
