Calf Barn - Natural Ventilation

Natural ventilation is best suited for calf barns located in regions with mild to temperate climates. The ventilation system relies on outdoor weather conditions and indoor temperature variations to create air exchanges in the barn.

During spring, summer, and fall, the system relies on sidewall openings to allow for adequate air movement for calves. During periods of hot weather, recirculation fans can be added to enhance air movement and calf comfort. In winter, minimum air exchanges can be maintained through a ridge opening with limited sidewall openings. The natural system is generally limited to small and medium-sized calf barns due to the physical limitations of the ventilation principles.
