ABSTRACT OF THE DISCLOSURE An attic ventilation system is provided for a building which is normally elevated above ground. The ventilation system comprises an insulated duct extending upward from building floor to building ceiling to provide air communication between the air space under the building and the building attic. Positive suction, non-powered air exhausting devices are provided on the attic roof which are adapted to exhaust air from the attic in response to wind flowing over the devices. This arrangement prevents the accumulation of snow in the attic, particularly in harsh winter environments such as the Arctic.
