1. Which primary goal defines the role of an energy auditor in residential
buildings?
A. Increasing property value through renovation
B. Enhancing aesthetic appeal of the structure
C. Identifying opportunities to improve energy efficiency and reduce
consumption
D. Certifying structural integrity of buildings
The primary function of an energy auditor is to evaluate energy
usage and identify cost-effective measures to reduce energy
consumption and improve efficiency.
2. What instrument is commonly used to detect air leakage in a building
envelope?
A. Hygrometer
B. Blower door
C. Manometer
D. Thermostat
A blower door is used to depressurize or pressurize a building,
making it easier to identify air leaks through infiltration points.
3. Which unit is used to measure electrical energy consumption?
A. Volt
B. Ampere
C. Kilowatt-hour (kWh)
, D. Ohm
Kilowatt-hour is the standard unit used to quantify electrical energy
usage over time.
4. What does R-value measure in building materials?
A. Airflow resistance
B. Structural strength
C. Heat generation
D. Thermal resistance
R-value indicates a material’s resistance to heat flow; higher values
mean better insulation performance.
5. Which system typically consumes the most energy in a residential
home?
A. Lighting
B. Refrigeration
C. Heating and cooling (HVAC)
D. Electronics
HVAC systems account for the largest portion of energy use due to
temperature regulation demands.
6. What is the purpose of a duct leakage test?
A. Measure water pressure
B. Evaluate insulation thickness
C. Determine air loss in HVAC duct systems
D. Assess electrical load
Duct leakage testing identifies inefficiencies caused by air escaping
from ducts, reducing system performance.
7. Which of the following is a renewable energy source?
A. Natural gas
B. Coal
C. Solar energy
D. Diesel
Solar energy is renewable because it is continuously replenished by
the sun.
8. What does SEER stand for in HVAC systems?
A. System Energy Efficiency Ratio
B. Seasonal Energy Efficiency Regulation
, C. Seasonal Energy Efficiency Ratio
D. Standard Energy Evaluation Rate
SEER measures the cooling efficiency of air conditioners over a typical
season.
9. Which building component is most responsible for heat loss in poorly
insulated homes?
A. Floors
B. Doors
C. Windows
D. Walls and attic
Walls and attic spaces represent large surface areas where
significant heat transfer can occur if not properly insulated.
10. What is the main function of insulation?
A. Block sound transmission
B. Increase airflow
C. Reduce heat transfer
D. Enhance lighting
Insulation slows the movement of heat, helping maintain indoor
temperatures efficiently.
11. Which tool measures temperature differences across surfaces?
A. Voltmeter
B. Infrared thermometer
C. Barometer
D. Lux meter
Infrared thermometers detect surface temperature variations, useful
for identifying insulation gaps.
12. What does a home energy rating score indicate?
A. Structural stability
B. Market value
C. Energy efficiency performance
D. Occupant comfort level
Energy rating scores provide a standardized measure of how
efficiently a home uses energy.
13. Which type of lighting is most energy-efficient?
A. Incandescent
