Attaching data from a SW FL home with a/c-dehumidification-fresh air ventilation for 2 weeks, followed by cool dry weather without a/c or dehumidification. Observe the lower inside dew point while the outside dew points are high. During not dehu or a/c, the inside dew point follows the outside dew point. Additional fresh dry air ventilation reduces the humidification effect from the occupants. Fresh air ventilation and dehumidification are important for air tight well insulated homes.
