Qualified Products List View list

  • Ventilation fans must have been tested by the Bio Environmental and Structural Systems Laboratory (bess.illinois.edu) or the Air Movement and Control Association Internal Inc. Laboratory (www.amca.org).
  • Only the tested fan configuration will be eligible. Additional non-tested accessories such as cones, shutters, or boxes will not qualify. For safety reasons, accessory wire guards are allowed even if not tested.
  • Ventilation fans must meet minimum efficiencies in the charts below.
  • Efficiency Vermont strongly encourages the use of fan controls (thermostats, timers, etc.) and staging/banking of fans when possible to maximize energy savings.
  • Rebate amounts are specific to dairy barn installations. Other agricultural facilities may qualify for a custom rebate. Contact Efficiency Vermont for more information.
