1. What is the primary goal of an energy audit?
A. Increase energy prices
B. Improve building aesthetics
C. Reduce energy consumption and costs
D. Replace all equipment
Answer: C
Rationale: Energy audits systematically identify opportunities to reduce
energy use and operating costs without compromising performance.
2. Which type of energy audit is the most detailed and comprehensive?
A. Walk-through audit
B. Benchmarking audit
C. Investment-grade audit
D. Preliminary audit
Answer: C
Rationale: Investment-grade audits involve detailed analysis,
measurements, and financial evaluation to support capital investment
decisions.
3. What instrument is commonly used to measure electrical current?
A. Voltmeter
B. Ammeter
C. Thermometer
D. Hygrometer
, Answer: B
Rationale: An ammeter directly measures the flow of electrical current in
amperes.
4. Which unit is used to measure energy consumption?
A. kW
B. kVA
C. kWh
D. V
Answer: C
Rationale: Kilowatt-hours represent energy used over time, which utilities
bill customers for.
5. Load factor is defined as:
A. Peak load divided by average load
B. Average load divided by peak load
C. Connected load divided by peak load
D. Demand divided by voltage
Answer: B
Rationale: Load factor indicates how evenly energy is used by comparing
average to peak demand.
6. Which system typically consumes the most energy in commercial buildings?
A. Lighting
B. Plug loads
C. HVAC
D. Elevators
Answer: C
Rationale: HVAC systems usually dominate energy use due to heating,
cooling, and ventilation demands.
7. What does HVAC stand for?
A. Heating, Ventilation, and Air Conditioning
B. High Voltage Air Control
C. Heating, Voltage, and Cooling
, D. Humidity, Ventilation, and Air Control
Answer: A
Rationale: HVAC refers to systems controlling indoor thermal comfort and
air quality.
8. Which lighting technology is the most energy-efficient?
A. Incandescent
B. Halogen
C. Fluorescent
D. LED
Answer: D
Rationale: LEDs provide high light output with significantly lower energy
consumption and longer lifespan.
9. Power factor is the ratio of:
A. kVA to kW
B. kW to kVA
C. Voltage to current
D. Resistance to reactance
Answer: B
Rationale: Power factor compares real power (kW) to apparent power
(kVA).
10.A low power factor indicates:
A. Efficient energy use
B. Excessive real power
C. Higher reactive power
D. Reduced voltage
Answer: C
Rationale: Low power factor means more reactive power, increasing losses
and utility penalties.
11.Which device is used to improve power factor?
A. Transformer
B. Capacitor bank
