What is the primary purpose of building science in residential construction?
Answer: Analyze energy, moisture, and air flow
Building science focuses on the interaction between building components and environmental forces to enhance performance and durability.
What does the building envelope refer to?
Answer: Exterior shell of the building
The building envelope includes all exterior elements—walls, roof, windows, and foundation—that separate indoors from outdoors.
Why is air sealing important in home energy efficiency?
Answer: To minimize air leakage
Air sealing reduces drafts and uncontrolled air exchange, increasing comfort and lowering energy bills.
Which factor most affects the rate of heat transfer in a building?
Answer: R-value of insulation
Thermal resistance (R-value) of materials determines how effectively heat is slowed from moving through a building assembly.
What is a potential problem caused by poor vapor barrier installation?
Answer: Mold and moisture damage
Improper vapor barrier placement can lead to condensation within walls, promoting mold growth and material decay.
What role does ventilation play in building science?
Answer: Controls indoor air quality
Ventilation controls indoor air quality by exchanging stale air with fresh air, reducing pollutants and humidity.
