Abstract: The static pressure within an air-supported structure is monitored and controlled in accordance with monitored environmental conditions. The static pressure is kept at the minimum value required to maintain the structures's integrity, thereby using a minimum amount of energy. As outside wind velocity incrementally increases, the static pressure is increased incrementally. Under certain weather conditions such as high winds and frozen precipitation, the static pressure is increased to a maximum limit. As a safety feature, a secondary inflation device is activated to assist a primary inflation device to quickly increase pressure in the structure in response to a sudden loss in pressure.
