Building Performance – Lesson 1.
1. Heat flows from warm to cold.
That’s correct! Heat doesn’t flow up. Hot air goes up but heat travels from warm to cold.
…
In the winter, heat inside the house wants to travel out. In the summer, heat outside wants to travel in.
This is particularly relevant to wall systems. Walls represent a large surface area of the house that is directly exposed to the elements.
This flow of warm to cold not only affects comfort & energy loss, it also brings moisture and uncontrolled airflow into the walls.
We manage this flow of energy & moisture and by:
1. Air sealing
2. Installing insulation properly
3. Window selection
