You're nearing the end of a soothing hot shower, a roast is browning in the oven, potatoes are boiling on the cook-top, the last load of laundry is in the dryer, the water heater just kicked on to provide some more hot water for your shower and the heater is keeping your home at just the right temperature.
Each one of those activities creates moisture inside a home and hopefully the house is properly ventilated to provide enough fresh air circulation to sufficiently dissipate that moisture and transfer it to outside the building.
In older homes, the construction methods left air leaking through and around windows, doors, walls, floors and ceilings. Plus, once upon a time ceiling vents were commonly installed in closets, kitchens, bathrooms and laundry rooms.
Since the gas crisis of the 1970's, the concept of energy conservation has been driving architectural design, construction materials and building codes toward tighter more energy efficient living spaces. The concepts are sound and well-founded in good logic except to a large degree they fail to factor in the sharp reduction or even the elimination of fresh air circulation in most areas.
