Natural ventilation system for a cowshed comprises an incoming air channel (1), an outgoing air channel (2), a heater (9), outgoing air openings (11), and incoming air openings (12). The incoming air channel and the outgoing air channel are joined together in a pipe-in-pipe system with a trapezoidal intermediate wall (3) and are arranged along the walls and roofs to utilize the heat produced inside. Preferred Features: The incoming air channel and the outgoing air channel are connected to a deflector (6) having a two-sided effect to utilize the wind pressure.
