Energy Auditor Professional Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of an energy audit?
• To inspect electrical wiring
• To identify opportunities to reduce energy consumption and costs
• To install solar panels
• To monitor employee productivity

Rationale: An energy audit systematically evaluates energy use in

buildings or facilities to identify ways to reduce energy consumption and save costs.

• Which of the following is considered a non-renewable energy source?
• Wind
• Solar
• Coal 1 / 4

• Hydropower

Rationale: Coal is a fossil fuel, which is finite and non-renewable,

unlike wind, solar, or hydropower.

• What is the most common method for measuring energy consumption

in a facility?

• Thermography
• Electricity meters
• Gas chromatography
• Hygrometry

Rationale: Electricity meters provide direct readings of electrical

consumption, the most common energy measurement in buildings.

• Which HVAC component is primarily responsible for removing heat

from indoor air?

• Furnace
• Air conditioner evaporator coil
• Air filter
• Boiler

Rationale: The evaporator coil in an air conditioner absorbs heat

from indoor air, cooling the space.

• What is the function of a power factor in electrical systems?
• Measures energy efficiency of motors
• Indicates the phase difference between voltage and current
• Determines insulation resistance 2 / 4

• Controls thermostat settings

Rationale: Power factor indicates the phase difference between

voltage and current; it affects the efficiency of electrical power delivery.

• Which of the following lighting technologies is most energy-efficient?
• Incandescent
• Fluorescent

C) LED

• Halogen

Rationale: LED lighting provides the highest efficiency with lower

energy consumption and longer lifespan than incandescent or fluorescent bulbs.

• In building energy audits, which type of energy loss is most often

addressed first?

• Transmission losses
• Heating, ventilation, and air conditioning (HVAC) losses
• Pump inefficiencies
• Lighting controls

Rationale: HVAC systems are typically the largest consumers of

energy in buildings, so audits focus on these losses first.

• Which of the following best defines “demand-side management”

(DSM)?

• Controlling utility pricing 3 / 4

• Strategies to reduce energy consumption on the customer side
• Installing new power plants
• Monitoring grid stability

Rationale: DSM refers to programs or techniques to manage energy

use by end-users, reducing peak demand and total energy consumption.

• What is the unit of energy commonly used in building energy audits?
• Watts
• kWh (kilowatt-hour)
• Joules per second
• Amperes

Rationale: Energy consumption is typically measured in kilowatt-

hours (kWh), representing electricity used over time.

• Which thermographic method is used in energy auditing to

detect insulation deficiencies?

• Ultrasonic testing
• Infrared thermography
• X-ray imaging
• Calorimetry

Rationale: Infrared thermography detects surface temperature

differences, revealing heat loss or insulation gaps.

• What is the typical efficiency range of a standard gas-fired

boiler?

• / 4
