1. What is the primary purpose of building insulation?
A. Increase air leakage
B. Reduce heat transfer
C. Increase moisture movement
D. Increase electrical consumption
Answer: B. Reduce heat transfer
Rationale: Insulation slows heat flow through walls, ceilings,
floors, and other building assemblies.
2. Which unit is commonly used to describe the thermal
resistance of insulation?
A. PSI
B. CFM
C. R-value
D. BTU/minute
Answer: C. R-value
Rationale: R-value indicates resistance to heat flow; higher R-
values generally provide greater resistance.
,3. What does a higher insulation R-value generally indicate?
A. Lower thermal resistance
B. Greater thermal resistance
C. Greater air leakage
D. Greater moisture absorption
Answer: B. Greater thermal resistance
Rationale: A higher R-value means the material resists
conductive heat transfer more effectively.
4. Which condition can significantly reduce the effective
performance of insulation?
A. Proper installation
B. Compression or gaps
C. Correct thickness
D. Continuous coverage
Answer: B. Compression or gaps
Rationale: Voids, compression, and discontinuities can create
thermal weak points and reduce effective insulation
performance.
5. What is air sealing primarily intended to control?
A. Unwanted air movement
B. Structural loads
C. Water pressure
D. Electrical resistance
,Answer: A. Unwanted air movement
Rationale: Air sealing reduces uncontrolled infiltration and
exfiltration through cracks, joints, penetrations, and openings.
6. Which location is commonly a major source of air leakage?
A. Sealed concrete surface
B. Plumbing and electrical penetrations
C. Solid metal plate
D. Finished flooring without joints
Answer: B. Plumbing and electrical penetrations
Rationale: Penetrations through walls, ceilings, and floors can
provide pathways for uncontrolled airflow.
7. What is infiltration?
A. Intentional exhaust ventilation
B. Uncontrolled entry of outdoor air into a building
C. Heat transfer through insulation
D. Solar heat gain
Answer: B. Uncontrolled entry of outdoor air into a building
Rationale: Infiltration occurs when outside air enters through
cracks and openings in the building envelope.
8. What is exfiltration?
A. Uncontrolled movement of indoor air to the exterior
, B. Mechanical cooling
C. Water drainage
D. Heat recovery
Answer: A. Uncontrolled movement of indoor air to the
exterior
Rationale: Exfiltration is the movement of conditioned indoor
air through leaks to the outside.
9. Which tool can be used to identify air leakage during an
energy-efficiency assessment?
A. Blower door
B. Torque wrench only
C. Pipe cutter
D. Voltage tester only
Answer: A. Blower door
Rationale: A blower-door test creates a pressure difference
that helps identify and quantify building-envelope air leakage.
10. What does a blower-door test primarily measure?
A. Water pressure
B. Building air leakage
C. Electrical resistance
D. Refrigerant pressure
Answer: B. Building air leakage
Rationale: Blower-door testing evaluates how much air moves
