Before you begin
- Rowan owns a small house. The reading chair feels drafty beside the closed north entry on windy evenings. No water damage or equipment fault has been reported.
- Set a bounded comfort goal and identify a reasonable first investigation.
- Use the supplied hypothetical case or an authorized non-confidential alternative.
You do not need construction experience to begin. Start by separating what you notice from what you think causes it. All households, observations, prices and dates used in exercises are hypothetical. You can finish every task with the supplied cases. A real-home alternative is optional, subject to permission and the safety checks taught here.
Lesson result: Set a bounded comfort goal and identify a reasonable first investigation.
