These 10 free EMP questions are organized by exam domain, so you can see how each part of the Energy Management Professional Certification (EMP) blueprint is tested. Reveal the answer and explanation under each question.
A recreation center used 480 MMBtu of gas in its baseline year and 510 MMBtu after a controls upgrade. The approved baseline model predicts that the old controls would have used 560 MMBtu under the reporting year's weather and operating hours. Meter boundaries are unchanged, and no additional adjustment is needed. How much avoided gas use is supported by this comparison?
Correct answer: C - 50 MMBtu of avoided use
Portfolio screening has identified a municipal office for further study. The owner commissions an end-use breakdown, engineering estimates of practical measures' costs and savings, and an assessment of their operating and maintenance effects. No capital-intensive modification has yet been selected for detailed investment analysis. This assignment corresponds to which ASHRAE audit service?
Correct answer: C - Level 2: Energy survey and engineering analysis
An electrically powered process offers recoverable heat throughout the year. A proposal would use it only for winter space heating; no summer heat use or seasonal storage is available. Heat temperature, exchanger performance, seasonal boiler efficiency, and added pump costs have been checked. The proposal divides all annual recoverable heat by boiler efficiency and values the result at the boiler's fuel price. Identify the decisive overstatement.
Correct answer: D - It credits recovered heat when no heating demand exists.
An office's monthly electricity model was fitted using months with 0-280 cooling degree days and achieved R² = 0.97. A reporting month has 430 cooling degree days. Meter checks pass and operations are otherwise unchanged. The analyst proposes publishing the difference between predicted and actual electricity as verified savings. Which review comment is warranted?
Correct answer: A - Validate the model's behavior outside the weather range represented in its fitted data.
At steady operation, independent calibrated measurements immediately before and after an air handler's hot-water heating coil read 18°C and 24°C. The hot-water loop is running, but the control system commands the heating valve closed and inspection finds its actuator at the closed stop. No other heat source lies between the measurement points. What mechanism best accounts for these observations?
Correct answer: B - Hot water passing a valve that indicates closed.
An air handler is operating in conditions suitable for economizing. Physical checks verify maximum permitted economizer airflow. Mixed air is 64°F, and the required supply-air target is 55°F. The documented sequence permits supplemental mechanical cooling, which brings supply air to the target. All protective limits are met. The commissioning record should classify this operation as:
Correct answer: D - Normal integrated cooling: outdoor air provides partial cooling, and mechanical cooling meets the remaining load.
A distribution center's controls retrofit saves 6,200 kWh in one month and reduces that month's measured 15-minute peak demand from 300 kW to 245 kW. The tariff charges $0.13/kWh and $18 per billed kW. Billed demand is the greater of the current monthly peak or 75% of the preceding 11-month maximum, which remains 420 kW in both comparisons. All other charges are unchanged. How much does the retrofit reduce this month's bill?
Correct answer: B - $806
An unconditioned warehouse will receive efficient luminaires and occupancy controls. Changing run time is expected to produce most of the savings, but current lighting hours are undocumented. Lighting circuits can be metered independently, the old installation is still operating, and unrelated warehouse loads fluctuate substantially. The owner wants verified savings for the lighting project alone. Select the strongest measurement plan.
Correct answer: A - Measure circuit input power and actual run time before and after installation over representative operating conditions.
Two consultants evaluate an office upgrade. One estimates LED savings against the existing lighting; the other estimates replacement-chiller savings using the office's original cooling load. The lighting will be replaced first, the office is gas-heated in winter, and both estimates are proposed for addition into one package total. Before approving that total, the energy manager should require:
Correct answer: A - A combined assessment using the reduced lighting heat gain for both cooling and heating operation.
An office owner consumes electricity from its rooftop solar array but sells all renewable energy certificates (RECs) generated by the array. It acquires no replacement renewable attributes. Which statement is supportable in the owner's public energy report?
Correct answer: B - We generate solar electricity on site and sell the associated renewable energy attributes.
