摘要：

A naturally ventilated greenhouse with ridge and side openings in a tropical region has to deal with high temperatures, which adversely affect crop growth. Increasing ventilation rate decreases temperature in the greenhouse. Ventilation rates were predicted using the energy balance method and a model based on wind and buoyancy forces. Good agreement was obtained between prediction and measurement.
