Question 1
Which system is primarily responsible for maintaining indoor thermal
comfort in a multifamily building?
A. Electrical distribution system
B. HVAC system
C. Plumbing system
D. Structural framing system
Answer: B. HVAC system
Rationale: The HVAC system (Heating, Ventilation, and Air
Conditioning) regulates temperature, humidity, and air circulation,
making it the primary system responsible for indoor thermal comfort.
Question 2
What is the primary purpose of a blower door test?
,A. Measure electrical load
B. Test plumbing pressure
C. Determine building air leakage
D. Evaluate insulation R-value
Answer: C. Determine building air leakage
Rationale: A blower door test depressurizes a building to measure the
rate of air infiltration and exfiltration, helping identify envelope
leakage.
Question 3
Which building component is most directly responsible for reducing
heat transfer?
A. Windows
B. Insulation
C. Electrical wiring
D. Roof shingles
Answer: B. Insulation
Rationale: Insulation slows conductive heat transfer between
conditioned and unconditioned spaces, improving energy efficiency.
,Question 4
What does R-value measure?
A. Airflow resistance
B. Thermal resistance
C. Electrical resistance
D. Moisture resistance
Answer: B. Thermal resistance
Rationale: R-value indicates a material’s ability to resist heat flow;
higher values indicate better insulation performance.
Question 5
Which is a common symptom of negative pressure in a building?
A. Reduced energy bills
B. Backdrafting of combustion appliances
C. Increased insulation performance
D. Improved ventilation efficiency
Answer: B. Backdrafting of combustion appliances
Rationale: Negative pressure can cause combustion gases to reverse
flow into living spaces, creating safety hazards.
, Question 6
Which instrument is used to measure temperature and humidity
simultaneously?
A. Manometer
B. Hygrometer
C. Psychrometer
D. Anemometer
Answer: C. Psychrometer
Rationale: A psychrometer uses wet-bulb and dry-bulb temperatures
to determine relative humidity.
Question 7
What is the primary function of a vapor barrier?
A. Increase airflow
B. Prevent moisture diffusion
C. Increase heat transfer
D. Improve electrical grounding
Answer: B. Prevent moisture diffusion
Rationale: Vapor barriers reduce moisture movement through building
assemblies, preventing condensation issues.
