The inverter automatically shuts down to prevent grid overvoltage

Correct answer: Excess generation is exported to the grid and credited against future utility bills

Under net metering, excess PV generation flows back to the grid and the facility receives a credit (typically at retail rate) that offsets future electricity charges.

Question 36: A facility manager is evaluating two lighting retrofit options. Option A has a simple payback of 2 years; Option B has a simple payback of 4 years but a higher NPV over 10 years. Which statement is most accurate?

Option A is always the better investment because it pays back faster
Simple payback and NPV will always agree on the best option
Option B may be the better long-term investment despite the longer payback (Correct answer)
Option B should be rejected because payback exceeds 3 years

Any PPE will provide adequate protection

Correct answer: PPE must be properly fitted, maintained, and replaced as needed

Regardless of experience level, PPE must be properly fitted, regularly maintained, and replaced when worn or damaged.

Question 146: A cooling tower's 'cycles of concentration' (COC) has dropped from 6 to 3. What is the most likely operational consequence?

Increased makeup water consumption and higher water treatment chemical costs (Correct answer)
Decreased blowdown frequency reducing water disposal costs
Lower condenser water supply temperature improving chiller efficiency
Reduced fan energy consumption due to lower airflow requirements

Correct answer: Increased makeup water consumption and higher water treatment chemical costs

Lower COC means more frequent blowdown is occurring, requiring more makeup water to replace it, increasing both water consumption and chemical treatment costs.

Question 147: A facility implements an occupancy-based HVAC setback strategy. Which scenario would yield the greatest energy savings?

A single-shift manufacturing plant with no weekend operations (Correct answer)
A data center with constant thermal loads
A 24/7 call center with constant occupancy year-round
A hospital emergency department with variable occupancy

Correct answer: A single-shift manufacturing plant with no weekend operations

A single-shift manufacturing plant with no weekend operations has the longest unoccupied periods, providing maximum opportunity for HVAC setback and consequently the greatest energy savings.

Question 148: Which IoT application in smart buildings automatically adjusts lighting levels based on occupancy and available daylight?

Demand-controlled ventilation
Variable frequency drive (VFD) control
Chilled water reset strategy
Daylight harvesting with occupancy sensors (Correct answer)

Correct answer: Daylight harvesting with occupancy sensors

Daylight harvesting combines photosensors and occupancy sensors with dimmable lighting controls to reduce electric lighting energy when sufficient natural light is available.

Question 149: Under ASHRAE 90.1, which building system is addressed by the lighting power density (LPD) requirements?

Plug load management for office equipment
Interior and exterior electrical lighting (Correct answer)
Emergency and exit lighting circuits
HVAC system sizing

Correct answer: Interior and exterior electrical lighting

ASHRAE 90.1 sets maximum lighting power density limits (W/sq ft) for interior and exterior lighting to ensure energy-efficient lighting design.

Question 150: When a Facilities Engineer uses QR codes or NFC tags on equipment assets, what primary workflow benefit is achieved?

Enabling remote shutdown of equipment from a smartphone
Automatically ordering replacement parts without human approval
Allowing maintenance technicians to instantly access asset records, manuals, and open work orders via mobile device (Correct answer)
Replacing the need for a CMMS entirely

Correct answer: Allowing maintenance technicians to instantly access asset records, manuals, and open work orders via mobile device

Asset tags linked to a mobile CMMS allow technicians to scan equipment in the field and immediately pull up its maintenance history, manuals, and associated work orders without returning to a desk.

Question 151: Which foundational principle is MOST important for success in Association for Facilities Engineering Certification?

Maintaining minimum certification requirements
Commitment to continuous learning, ethical practice, and quality outcomes (Correct answer)
Specializing in only one narrow area
Maximizing financial returns

Correct answer: Commitment to continuous learning, ethical practice, and quality outcomes

Success requires continuous learning, ethical practice, and focus on quality outcomes.

Certified Plant Engineer (CPE) Exam
