The system (1a) has a ventilation elements (3-1, 3-2) partially forming a ridge region of a building roof. The ventilation elements include support structures (5-1, 5-2), which are covered by flexible face sheets (9-1, 9-2) i.e. wear-proof, tear-proof tarpaulins. The support structures are formed as one-side opened frames. The support structures include longitudinal bars (6-1, 6-2) that are arranged on a roof side, and two transverse bars (7-1, 7-2) that are arranged orthogonal to the longitudinal bars. The ventilation elements are pivotably movably mounted around an axis. Independent claims are also included for the following: (1) a system for controlling a ridge system (2) a method for controlling a ridge system (3) an agricultural building (4) a system for controlling ventilation of an agricultural building (5) a method for controlling ventilation of an agricultural building. |
