A method and system for controlling the environment of storage facilities, including produce and livestock storage facilities, and the like. Movement of air within the facility is accomplished by air-handling units or fans. The speed of each fan is controlled by a variable-speed drive, allowing the fans to run at speeds below full capacity. Environmental parameters, such as temperature or humidity, are monitored to determine the existing state of the environment which is then compared to a desired state. The speed of the fans or air-handling units is adjusted to alter the existing environmental state, bringing it in alignment with the desired state. The fans or air-handling units are operated continuously, typically at reduced capacity. Other various facets are included with the system and method, including the control of the admittance of external air into the storage facility.

1. A method of controlling an internal environment of a storage facility, the method comprising:providing at least one fan for inducing air movement within the storage facility; continuously operating the at least one fan at less than full speed; flowing air directly through the at least one fan, through an air plenum and into the storage facility; sensing at least one internal environmental parameter; and varying speed of the at least one fan according to the at least one sensed internal environmental parameter.
