Moisture in buildings must be properly managed for our health and well being. Too little moisture creates discomfort while too much can result in mold and associated environmental illnesses. We concentrate on how much moisture must managed in a home due to climatic, construction, occupancy and ventilation variations. We discuss different methods for dehumidifying and humidifying air, and methods for determining humidity level of indoor air. The moisture and energy benefits of “smart” ventilation over constant flow ventilation (ASHRAE 62.2-2016 table) are discussed. Finally, we examine annual energy performance of a humidity managed home.
