A computer simulation program, FLUENT V4, was used to determine ventilation rates and air flow patterns of a multi-span sawtooth greenhouse under various roof and side vent opening configurations and outside wind speeds. The analytical method used was based on computational aerodynamics. The combined effects of roof and windward side openings resulted in ventilation rates up to four times recommended for average wind speeds. The method and the software used adequately simulated previous wind tunnel and computational studies of natural ventilation designs and the results of multi-span sawtooth simulations exceeded the recommended ventilation rates found in the literature.
