A system and related method are disclosed for controlling condensation in a space. The system includes a fan and a sensor for sensing an environmental condition, such as temperature, humidity, or both. For instance, the sensors may sense an air temperature that is used to estimate or predict a surface temperature of an object within the room. The system also includes a controller capable of receiving controlling the fan based on the surface temperature. The system may additionally include a heater and/or a damper for transferring outside air into the space, either of which may be controlled by the controller based on the measurements.
