1. The primary purpose of a comprehensive home energy audit is to
identify opportunities to
A. Increase property value
B. Reduce energy consumption and improve comfort
C. Upgrade appliances only
D. Meet real estate disclosure requirements
Answer: B
Energy audits focus on reducing energy use while improving
comfort, safety, and durability.
2. Which diagnostic tool is most commonly used to measure whole-
house air leakage?
A. Combustion analyzer
B. Blower door
C. Infrared thermometer
D. Manometer only
Answer: B
A blower door depressurizes or pressurizes the home to quantify
air leakage.
3. During a blower door test, air leakage is typically reported in
A. PSI
, B. BTU/hr
C. CFM50
D. SEER
Answer: C
CFM50 represents cubic feet per minute of airflow at 50 Pascals.
4. Which condition presents the highest immediate health risk
during an energy audit?
A. Low insulation levels
B. Carbon monoxide spillage
C. Single-pane windows
D. Duct leakage
Answer: B
Carbon monoxide exposure poses an immediate and potentially
fatal risk.
5. The neutral pressure plane in a house is best described as the
level where
A. Indoor and outdoor temperatures are equal
B. Stack effect is eliminated
C. Indoor and outdoor air pressures are equal
D. Airflow is greatest
Answer: C
Above and below this plane, pressure differences drive infiltration
and exfiltration.
6. Infrared thermography is most effective when there is a minimum
indoor-outdoor temperature difference of
A. 5°F
B. 10°F
, C. 15°F
D. 25°F
Answer: C
A sufficient temperature delta improves the visibility of thermal
anomalies.
7. Which building component typically contributes most to heat loss
in cold climates?
A. Floors
B. Windows
C. Roof/ceiling
D. Walls
Answer: C
Heat rises, making ceilings and roofs a major pathway for heat
loss.
8. What is the primary function of a pressure pan test?
A. Measure room-to-room pressure balance
B. Identify duct leakage locations
C. Measure whole-house leakage
D. Test combustion safety
Answer: B
Pressure pans help locate and assess duct leaks under blower door
operation.
9. Which fuel type requires the most stringent combustion safety
testing?
A. Electric
B. Natural gas
C. Oil
