Building Science Basics

This course introduces the science behind energy efficiency, occupant comfort, health, and safety.

The house functions as a system, made up of many different components and systems:

• The envelope (foundation, walls, floors, ceilings and attics, doors and windows)
• Heating, cooling and ventilation equipment and distribution
• The surrounding environment
• The occupants and their behaviour in the house

Each of these components is affected by the interactions of heat, air and moisture flow in, out, and around the house. All of the interactions impact indoor air quality and the need for ventilation.

Upon completion, you will know how these components are affected by the interactions of heat, air and moisture flow in a house, and how those interactions impact indoor air quality and the need for ventilation.
