1. A method, comprising:
determining a dew point set point;
determining a dew point of conditioned air from a space within a building;
in response to determining that the dew point satisfies the dew point set point, determining a vent air dew point of air in an external environment surrounding the building;
in response to determining that the vent air dew point is below the dew point set point by a dew point threshold:
controlling a connecting member of a damper assembly to position a first damper of the damper assembly in an open position to exhaust conditioned air to a vent exhaust opening fluidly coupled to the external environment, and to position a second damper of the damper assembly in a closed position to substantially prevent recirculation of the conditioned air to the space within the building; and
controlling an air driver of an dehumidifier to exhaust the conditioned air from the space through the dehumidifier to the external environment; and
in response to determining that the vent air dew point satisfies the dew point set point or is within the dew point threshold of the dew point set point:
activating a compressor of the dehumidifier to reduce a moisture level of the conditioned air within the space within the building; and
controlling the connecting member to position the first damper in the closed position to substantially prevent exhausting the conditioned air to the vent exhaust opening and positioning the second damper in the open position to circulate the conditioned air to the space within the building.
