Abstract
A method for ventilating an animal enclosure using a plurality of closable ventilation openings. Sensors measure ambient outside temperature and ambient atmospheric pressure. A controller correlates said measurements for temperature, and pressure to determine a differential pressure between the interior of said enclosure and atmospheric pressure. Air is then transported by said fans to draw said air in a predetermined volume to achieve said determined differential pressure.
