Abstract
A method of controlling moisture reaching a building façade may include providing a weather resistant building shield, the shield including first and second subchannels. The building shield may be disposed parallel to an inner façade and separated from the inner façade by an air gap. The method may include causing input air to flow through the first subchannel at an input air flow rate and causing exhaust air to flow through the second subchannel at an exhaust air flow rate. Controlling at least one of the input and exhaust air flow rates may provide control over moisture content in the gap.
Claims20
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, and
- a 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.

A method of ventilating a building, comprising:
- providing a building shield including a heat and moisture exchanger disposed between an interior face of the building shield and an exterior weather-resistant face of the building shield;
- disposing the building shield with the interior face parallel to a front surface of a building and separated from the front surface by a gap, and with the exterior face exposed to an environment external to the building;
- causing input air to flow from the environment external to the building into a first subchannel of the exchanger, through the first subchannel and into an interior of the building at an input air flow rate;
- causing exhaust air to flow from the interior of the building into a second subchannel of the exchanger, through the second subchannel and to the environment external to the building 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 input air and the exhaust air.

A method of controlling moisture reaching a building inner façade, comprising:
- providing a building outer façade including a heat and moisture exchanger disposed between an interior face of the outer façade and an exterior weather-resistant face of the outer façade;
- disposing the outer façade with its interior face parallel to a building inner façade and separated from the inner façade surface by a gap, and with its exterior face exposed to conditions of an ambient outdoor environment;
- causing input air to flow from the ambient outdoor environment into a first subchannel of the exchanger, through the first subchannel, across the gap, through the inner façade and into the building at an input air flow rate;
- causing exhaust air to flow from the building, across the gap, into a second subchannel of the exchanger separated from the first subchannel by a moisture permeable, gas-impermeable barrier, through the second subchannel and out to the ambient outdoor environment 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 outer façade and the gap, thereby controlling moisture content within the gap.
