Ventilation device (1) for conveying air into and out of rooms in a building, consisting of a housing (2) arranged in a wall (3) of the building, having a first side face (4) facing the room interior (5) of the building, which first side face has on a lower plane (15) an outlet opening (26) for the inbound air flow (9) of a lower air flow duct (19) and an inlet opening (27) for the outbound air flow (10) of a lower air flow duct (20), and a second side face (6) facing the exterior (7), which second side face has on an upper plane (14) respective inlet and outlet openings (24, 25) for the reciprocal inbound and outbound air flows (9, 10) of the upper air flow ducts (17, 18), with a heat storage unit (11) for transferring heat from the outbound air flow (10) to the inbound air flow (9), and with a closure and opening device (12) for controlling the air flow, wherein the housing (2), separated in the height direction (H) by a partition (13), forms the upper plane (14) and the lower plane (15), wherein an air delivery device (8) consists of one intake air fan (21) for the inbound air flow (9) and of two exhaust air fans (22, 22') for the outbound air flow (10), or of two intake air fans (21) for the inbound air flow (9) and of one exhaust air fan (22), wherein the air flow driven by one fan is driven continuously and the air flow driven by two fans is driven in cyclically alternating fashion in an air delivery device (8), and in each case connect the upper plane (14) to the lower plane (15), wherein the housing (2), having a length (L) in the upper plane (14) with two arranged fans (22, 22'), forms, by means of in each case one closure and opening device (12), two upper air flow ducts (17, 18), and has in the lower plane (15) with one arranged fan (21) establishing by spatial separation two lower air flow ducts.
