These 10 free EEP questions are organized by exam domain, so you can see how each part of the Energy Efficiency Practitioner (EEP) blueprint is tested. Reveal the answer and explanation under each question.
The financial case for a campus gas-turbine combined heat and power project credits every unit of recoverable exhaust heat with displacing boiler output. The proposed system has no thermal storage. Which additional evidence most directly tests that assumption?
Correct answer: D - Heating-load profiles matched to the timing and temperature of the proposed recovered heat
A plant is billed for kWh and monthly peak kVA. A power-factor correction proposal predicts a 12% reduction in billed kVA and assumes the same percentage reduction in annual kWh. Production, operating hours, and required motor shaft work will be unchanged. Which correction belongs in the financial analysis?
Correct answer: C - Value lower kVA demand charges and assess distribution-loss savings separately.
For an upcoming billing month, a factory projects a highest 15-minute average demand of 540 kW without staggered starts and 450 kW with them. Its tariff bills the greater of that month's maximum or 75% of the preceding 11 months' highest peak, 640 kW. At $15 per billed kW per month, what demand-charge saving would staggering produce?
Correct answer: B - $900
A failed ventilation fan must be replaced. A standard replacement costs $8,000 installed. A more efficient model costs $11,200 installed and qualifies for an immediate $800 rebate. It saves $600 annually in electricity relative to the standard model. Both meet the required duty and have equal service life and maintenance costs. What is the simple payback on the additional investment in efficiency?
Correct answer: C - 4.0 years
An office's ENERGY STAR Portfolio Manager score changes from 45 to 62 after worker count and weekly operating hours are corrected for the same assessment period. Meter readings and actual operations are unchanged. What does the higher score establish?
Correct answer: A - The corrected inputs changed the peer comparison, without demonstrating energy savings.
During a walk-through, an energy practitioner hears crackling and sees smoke emerging from a closed, energized switchboard. The practitioner is not electrically qualified or authorized to operate it. What is the appropriate immediate response?
Correct answer: D - Withdraw, warn others to stay clear, and activate the site's emergency response.
After an LED retrofit, quality inspectors report that familiar product colors look different. Task illuminance remains adequate, and the new lamps match the old lamps' correlated color temperature. Which specification would be most informative when investigating the complaint?
Correct answer: B - Color rendering index (CRI)
Droplets form along an uninsulated chilled-water pipe whose surface is 10°C. The room is 24°C with a dew point of 16°C, and a pressure test finds no leakage. Water and room conditions must remain unchanged. Which repair provides lasting condensation control?
Correct answer: B - Fit suitable insulation and seal all vapor-retarder seams, joints, and penetrations.
"Simultaneous heating and cooling" appears on a coastal hotel's energy dashboard. In its dedicated outdoor-air unit, the cooling coil is removing moisture and a downstream coil reheats the air. Required ventilation, supply temperature, and indoor humidity are maintained, and no equipment alarms are active. How should the practitioner respond to the flag?
Correct answer: A - Review the dehumidification sequence while maintaining ventilation and humidity control.
The sustainability team wants to describe a distribution center as using renewable electricity from its rooftop solar array. The array supplies some building loads, but every associated renewable energy certificate (REC) is sold, and none is purchased to replace it. Which statement is defensible?
Correct answer: A - The array reduces grid purchases; its associated renewable-use attributes have been sold.
