What is the primary purpose of a blower door test?
A. Measure indoor air temperature
B. Determine building air leakage rate
C. Test furnace efficiency
D. Measure carbon monoxide levels
Answer: B
The blower door is used to depressurize a home and measure air
leakage rates to assess envelope tightness.
Question 2
Which unit is commonly used to express air leakage in a home?
A. BTU
B. CFM50
,C. kWh
D. PSI
Answer: B
CFM50 represents cubic feet per minute at 50 Pascals of pressure,
standard for air tightness testing.
Question 3
What is the main function of insulation in a building?
A. Increase air leakage
B. Store electrical energy
C. Reduce heat transfer
D. Increase humidity
Answer: C
Insulation slows conductive heat transfer between conditioned and
unconditioned spaces.
Question 4
Which type of heat transfer involves direct contact?
A. Radiation
B. Convection
,C. Conduction
D. Evaporation
Answer: C
Conduction occurs when heat moves through solid materials in direct
contact.
Question 5
What does ACH50 measure?
A. Air changes per hour at natural conditions
B. Air changes per hour at 50 Pascals
C. Appliance heating capacity
D. Air conditioner horsepower
Answer: B
ACH50 measures how many times the air in a home is replaced per hour
at 50 Pa pressure.
Question 6
Which tool is used to detect thermal defects in building envelopes?
A. Manometer
B. Infrared camera
, C. Combustion analyzer
D. Hygrometer
Answer: B
Infrared cameras detect temperature differences indicating insulation
gaps or air leaks.
Question 7
What is the purpose of a combustion safety test?
A. Measure electrical load
B. Check refrigerant levels
C. Ensure safe operation of fuel-burning appliances
D. Measure airflow in ducts
Answer: C
Combustion safety testing ensures appliances operate without
producing harmful byproducts.
Question 8
Which gas is a primary indicator of incomplete combustion?
A. Oxygen
B. Nitrogen
