1. A method of controlling moisture reaching a building façade, comprising:
providing a weather-resistant building shield including:
an exterior weather-resistant face,an interior face,a membrane parallel to and disposed between the exterior face and the interior face and dividing an internal channel of the building shield into first and second subchannels,a first intake allowing fluid communication between an environment external to a building and the first subchannel,a second intake allowing fluid communication between an interior of the building and the second subchannel,a first egress allowing fluid communication between the first subchannel and the interior of the building, anda second egress allowing fluid communication between the second subchannel and the environment external to the building; disposing the building shield with the interior face parallel to a building façade and separated from the façade by a gap, and with the exterior face exposed to an environment external to the building; causing input air to flow into the first intake, through the first subchannel and out of the first egress at an input air flow rate; causing exhaust air to flow into the second intake, through the second subchannel and out of the second egress at an exhaust air flow rate; and controlling at least one of the input air flow rate and the exhaust air flow rate to provide a desired amount of heat exchange between the building shield and the gap, thereby controlling moisture content in the gap. |
