Preview
Preview: Planning and Estimating
Preview includes- 4 of 5 lesson topics
- 1 overview segment
- 3 core concepts
- 2 exam tips
Lesson Topics
- Envelope conduction
- Core rule or formula
- Scenario application
- Common exam trap
Overview
Focus: Envelope conduction. Walls, ceilings, floors, and partitions are commonly tested with U × A × ΔT.
Core Concepts
- Walls, ceilings, floors, and partitions are commonly tested with U × A × ΔT.
- Use a room-by-room load method rather than rules of thumb when the applicable design standard requires it.
- For steady conductive heat transfer, Q = U × A × ΔT; keep U-factor, area, and temperature-difference units consistent.
Exam Tips
- Write the equation before inserting numbers.
- Do not add or omit a load component just because it is small; follow the stated scope.
