Apparatus for automatic environmental control includes an enclosed, zoned structure. A heating, ventilation and air conditioning (HVAC) system is incorporated into the structure. Each zone includes separate controls, separately-controlled air flow into and out of each zone, and separate intake, vent, damper, thermostat and humidistat for each zone. Temperature and humidity are separately controllable for each zone, and controller is in communication with HVAC system for controlling HVAC system and for controlling the damper for each zone, the controller having a map comprising a plurality of relative humidity and temperature combinations and one or more actions for automatic execution based on the combinations of temperature and humidity. A temperature sensor, a relative humidity sensor are included in each zone, and an indicator array/interface panel is in communication with the controller. The system provides for the automatic elimination of environmental conditions favorable to mold and fungus growth for each zone individually.
