A Saw Tooth Naturally Ventilated Polyhouse (NVPH) is a specialized greenhouse structure designed with a roof configuration resembling the shape of saw teeth. This unique design incorporates alternating ridges and slopes, which optimize natural ventilation by enabling warm air to rise and escape through the elevated ridges while allowing cooler air to flow in through the lower sections. The sawtooth roof design is particularly effective in maintaining a stable microclimate within the polyhouse, ensuring proper air circulation, temperature control, and humidity regulation. This structure is widely used in agriculture for enhancing crop productivity while reducing energy consumption by eliminating the need for mechanical ventilation systems.
