1. The primary objective of an energy audit is to
A. Reduce maintenance costs
B. Improve indoor air quality
C. Identify and quantify energy-saving opportunities
D. Increase equipment lifespan
Correct Answer: C
Rationale: The core purpose of an energy audit is to systematically identify,
analyze, and quantify opportunities to reduce energy consumption and costs.
2. Which type of energy audit provides the most detailed analysis?
A. Benchmarking audit
B. Walk-through audit
C. Preliminary audit
D. Investment-grade audit
Correct Answer: D
Rationale: An investment-grade audit includes detailed measurements, financial
analysis, and engineering calculations suitable for capital investment decisions.
3. Energy Use Intensity (EUI) is expressed as
A. Energy cost per occupant
, B. Energy use per square foot per year
C. Energy use per hour
D. Energy demand per square foot
Correct Answer: B
Rationale: EUI measures annual energy consumption divided by the building’s
gross floor area.
4. Which instrument is most commonly used to measure electrical current?
A. Wattmeter
B. Multimeter
C. Ammeter
D. Voltmeter
Correct Answer: C
Rationale: An ammeter is specifically designed to measure electrical current.
5. Power factor is defined as the ratio of
A. Real power to apparent power
B. Apparent power to reactive power
C. Reactive power to real power
D. Voltage to current
Correct Answer: A
Rationale: Power factor indicates how effectively electrical power is being used,
defined as kW/kVA.
6. Low power factor in an electrical system typically results in
A. Reduced energy consumption
B. Higher utility demand charges
C. Lower line losses
D. Improved system efficiency
, Correct Answer: B
Rationale: Utilities often impose penalties or higher charges when power factor
is low due to increased system losses.
7. Which lighting technology has the highest luminous efficacy?
A. Incandescent
B. Halogen
C. Fluorescent
D. LED
Correct Answer: D
Rationale: LEDs provide the most lumens per watt among common lighting
technologies.
8. The primary purpose of an economizer in HVAC systems is to
A. Increase heating capacity
B. Reduce ventilation air
C. Use outdoor air for free cooling
D. Improve humidity control
Correct Answer: C
Rationale: Economizers reduce cooling energy by using cool outdoor air when
conditions permit.
9. Which HVAC component primarily controls indoor humidity?
A. Condenser
B. Evaporator coil
C. Compressor
D. Expansion valve
