Correct answer: Collect and route return air to the air handler

The return air plenum collects air from return ducts throughout the home and channels it back to the air handler for reconditioning.

Question 90: How does insulation improve a building’s performance?

Minimizes energy transfer (Correct answer)
Weakens walls
Adds structural strength
Increases noise

Correct answer: Minimizes energy transfer

Insulation works by creating a barrier that resists the flow of heat, whether it's trying to escape in winter or enter in summer. By minimizing this energy transfer, insulation helps maintain a stable indoor temperature. This reduces the workload on heating and cooling systems, leading to lower energy consumption and improved comfort.
