An air inlet hood for use with a ventilation system has an air inlet face to receive a flow of fresh ventilation air, and an air outlet face to deliver the air into the ventilation system. A rainwater collection channel is disposed along edges bounding the air inlet face to collect rainwater falling on the air inlet hood. A rainwater reservoir receives the collected rainwater from the rainwater collection channel, and dispenses the collected rainwater away from the air inlet face in order to prevent rainwater from being entrained into the ventilation air. |
