Worked examples: how to reason through CEM questions
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Example 1
Question: During an ASHRAE Level 2 energy audit of a manufacturing facility, which of the following activities would be most characteristic of this audit level?
- A simple walkthrough to identify obvious low-cost energy saving opportunities.
- A detailed whole-building computer simulation to model complex capital-intensive retrofits.
- A review of utility bills and a brief site survey to establish a baseline.
- A detailed breakdown and analysis of energy consumption by end-use, with financial analysis of recommended measures.
Answer: D. A detailed breakdown and analysis of energy consumption by end-use, with financial analysis of recommended measures.
Explanation:
Option D is correct. A Level 2 audit goes beyond a walkthrough: it breaks energy use down by end-use and adds a financial analysis of the recommended measures. Option A describes the lowest audit level, a simple walkthrough aimed at obvious low-cost opportunities. Option C also sounds like a basic starting point, since reviewing utility bills and a brief site survey only establishes a baseline. Option B describes detailed whole-building simulation, which belongs to a higher level used for large capital-intensive retrofits.
The rule to remember: each audit level adds depth. Walkthrough and bills come first, end-use breakdown and financial analysis come in the middle, and detailed modelling for major investments comes last.
Example 2
Question: When developing a floor plan, fire marshal regulations that limit the maximum travel distance to an exit directly impact the permissible length of which of the following?
- Dead-end aisles
- Main thoroughfares
- Perimeter aisles
- Registration queues
Answer: A. Dead-end aisles
Explanation:
Option A is correct. Fire rules limit how far a person must travel to reach an exit, and a dead-end aisle is the layout feature where someone can be farthest from a through route, so its length is capped. Main thoroughfares are wide routes that lead directly to exits, so they are not the problem the travel limit is aimed at. Perimeter aisles run along the walls and normally connect to exits. Registration queues are a crowd-flow matter, not a defined aisle type with a travel-distance cap.
The rule to remember: travel-distance limits shorten the parts of a layout that lead nowhere, because those are the places where people can be trapped.
Example 3
Question: Wind turbine power output is proportional to which mathematical relationship with wind speed?
- Linear (speed¹)
- Squared (speed²)
- Cubic (speed³)
- Logarithmic (ln speed)
Answer: C. Cubic (speed³)
Explanation:
Option C is correct. Power in the wind is proportional to the cube of wind speed, so a modest rise in speed produces a large rise in available power. Option A, linear, would understate that effect. Option B, squared, is closer but still too weak, and it is the relationship people often confuse with kinetic energy of a single mass. Option D, logarithmic, would mean gains flatten as speed rises, which is the opposite of what happens.
The rule to remember: power depends on the mass of air passing per unit time and on the kinetic energy of each unit of air, and both rise with speed. That combination gives the cubic relationship.
How to use these practice tests
Start with the official material. Read the AEE handbook and the body of knowledge study guide so you know the content areas and how the exam is run. Then attend the approved preparatory seminar that AEE requires, and keep the seminar materials close, because the exam is open book.
Next, take one of our practice sets for each content area where we have one, and do it without looking anything up first. Mark every question you got wrong or guessed. Then go back to your reference materials and find the answer there, noting the page or tab you used. The aim is to know where each method lives, so that on test day you are not searching for it while the clock runs on a 4-hour exam.
Spend extra time on calculation-heavy areas such as electrical systems, energy economics and HVAC, writing out each step instead of jumping to the answer. For areas where we do not yet have a practice set, such as controls, rates and storage, rely on the official study guide and your seminar notes.
In the last stretch, work through mixed sets under timed conditions to build pace. Remember that our questions are written with AI tools and are not real exam questions, so use them to practise reasoning, not to predict what will appear.

Sample CEM - Certified Energy Manager Practice Questions
Try these questions from our free CEM - Certified Energy Manager practice tests. The correct answer and an explanation follow each question.
A building's air handling unit (AHU) in a temperate climate is equipped with an air-side economizer. Under which condition should the economizer be fully utilized to provide 'free cooling'?
- A. When the outdoor air enthalpy is higher than the return air enthalpy.
- B. When the building is unoccupied and the outdoor temperature is below freezing.
- C. When the outdoor air dry-bulb temperature is 85°F and relative humidity is 90%.
- D. When the outdoor air is cool and dry enough to meet the cooling demand without mechanical refrigeration.
Answer: D. When the outdoor air is cool and dry enough to meet the cooling demand without mechanical refrigeration.
An air-side economizer provides 'free cooling' by using cool, low-humidity outside air instead of running the mechanical cooling (compressor) system. This is most effective when the outdoor air conditions are favorable (e.g., low temperature and/or low enthalpy) to cool the space directly, reducing or eliminating the need for mechanical refrigeration.
What is the typical efficiency range of commercial silicon photovoltaic (PV) solar panels under standard test conditions?
- A. 5–10%
- B. 15–22%
- C. 30–40%
- D. 45–55%
Answer: B. 15–22%
Commercial silicon PV panels typically achieve 15–22% efficiency under standard test conditions (STC) of 1,000 W/m² and 25°C.
Which statistical measure is commonly used to determine the reliability of a test?
- A. Mean
- B. Standard deviation
- C. Correlation coefficient
- D. Mode
Answer: C. Correlation coefficient
The correlation coefficient measures the degree of association between two variables and is often used to assess the reliability of a test.
Which blower door test result metric quantifies building envelope air tightness?
- A. ACH50 (air changes per hour at 50 Pa)
- B. CFM per ton of cooling
- C. Inches of water column static pressure
- D. Effective leakage area in square inches
Answer: A. ACH50 (air changes per hour at 50 Pa)
ACH50 expresses the number of whole-house air changes per hour when the building is pressurized to 50 Pascals, providing a standardized infiltration metric.
