1. Which principle is most central to the role of a Certified Energy
Manager when evaluating building performance improvements?
A. Maximizing aesthetic architectural design
B. Minimizing occupant interaction with systems
C. Reducing energy consumption while maintaining service levels
D. Increasing equipment redundancy regardless of cost
C
Energy management focuses on optimizing energy use to reduce
consumption while ensuring that occupant comfort, safety, and
operational requirements are maintained at acceptable levels.
2. A facility manager is analyzing utility bills and notices that demand
charges significantly increase total costs. What strategy best addresses
this issue?
A. Increase lighting levels during peak hours
B. Shift or reduce peak load demand through load management
C. Switch all loads to constant operation
, D. Increase transformer sizing without operational changes
B
Demand charges are driven by peak power usage, so load shifting,
peak shaving, and operational scheduling reduce maximum demand
and lower overall utility costs.
3. In an energy audit, which step is most critical for establishing a reliable
baseline?
A. Installing renewable energy systems immediately
B. Collecting historical utility consumption data
C. Replacing all inefficient equipment
D. Conducting employee energy awareness training
B
A reliable baseline depends on accurate historical energy
consumption data, which serves as the reference point for evaluating
savings.
4. Which financial metric is most commonly used to evaluate the
economic feasibility of energy conservation projects?
A. Internal combustion ratio
B. Simple payback period
C. Thermal conductivity index
D. Power factor correction rate
B
The simple payback period measures how long it takes for savings to
recover the initial investment, making it a widely used screening tool.
5. What is the primary purpose of a building energy management system
(BEMS)?
A. To eliminate all manual control of lighting
B. To automate and optimize building energy consumption
C. To increase equipment maintenance frequency
, D. To replace all mechanical systems with digital controls
B
A BEMS integrates monitoring and control functions to optimize
energy use across HVAC, lighting, and other building systems.
6. Which HVAC strategy typically yields the highest energy savings in
large commercial buildings?
A. Increasing fan speed continuously
B. Implementing variable air volume (VAV) systems
C. Running chillers at full load year-round
D. Increasing ventilation beyond design requirements
B
VAV systems adjust airflow based on demand, significantly reducing
energy consumption compared to constant volume systems.
7. What is the main advantage of conducting a level 2 energy audit
compared to a level 1 audit?
A. It eliminates the need for utility data
B. It includes detailed financial and engineering analysis
C. It requires no on-site inspection
D. It focuses only on lighting systems
B
A level 2 audit provides deeper analysis, including cost estimates and
savings calculations, enabling more informed investment decisions.
8. Which factor most directly affects the efficiency of electric motors?
A. Ambient humidity only
B. Load level relative to rated capacity
C. Paint color of motor casing
D. Type of building occupancy
B
, Motor efficiency is highly dependent on operating load, with
significant efficiency losses occurring at very low or very high loads.
9. In energy accounting, what does the term “energy intensity” refer to?
A. Energy used per unit of economic output or floor area
B. Maximum energy storage capacity
C. Peak electrical voltage levels
D. Equipment runtime duration
A
Energy intensity measures how much energy is consumed relative to
output or space, providing a normalized efficiency indicator.
10. Which renewable energy system is most commonly integrated
into commercial buildings for on-site generation?
A. Geothermal deep mining systems
B. Solar photovoltaic systems
C. Nuclear microreactors
D. Ocean thermal converters
B
Solar photovoltaic systems are widely adopted due to scalability,
declining costs, and ease of integration with building rooftops.
11. What is the primary function of a variable frequency drive
(VFD)?
A. Increase fixed motor speed
B. Control motor speed by varying frequency and voltage
C. Eliminate electrical resistance
D. Convert AC to DC permanently
B
VFDs regulate motor speed and torque by adjusting frequency and
voltage, leading to significant energy savings in variable load
applications.
