Controlling moisture flow in a building has significant impacts on occupant health and safety, comfort, building durability and energy efficiency. This section will cover the basics of moisture and its effects on the house system. It will also discuss how geographic location and house type can affect choices of moisture control strategies.
Applied building science is concerned with four different moisture transport mechanisms and the effects of that moisture flow:
- Bulk water movement (rain, snow, or groundwater)
- Capillary action (capillarity)
- Air transported moisture
