What the AFE is and how it works

According to Association for Facilities Engineering, “The exam consists of four modules, with up to two (2) hours to complete each module. Candidates may take all four (4) modules in one day, or complete them on different days.”^[1]

AFE offers several credentials for facilities and plant professionals; this page covers CPE, CPMM and CPS. All three exams are taken online. For CPE you email the AFE Credential Team with your preferred exam date. The CPMM exam is open book.

Scoring and format differ by credential. CPE has 4 modules with up to 2 hours for each, and you can sit them in one day or on different days. CPMM and CPS each need a combined average of at least 70% across 2 modules. The AFE pages we checked do not list a passing score for CPE, so confirm it with AFE.

Eligibility is based on experience and education:

• CPE: an engineering-related degree plus 4 years' management-level experience or 6 years' experience; 6 or 8 years with a non-technical degree or no degree; or PE plus 4 years.
• CPMM: 5 years' experience, or a 4-year related bachelor's degree, or 3 years' experience plus 2 years of related higher education.
• CPS: a high school diploma plus 5 years' professional experience, or 2 years supervisory within 5 years total.

If you do not pass CPMM or CPS, the first retake is free when taken within 30 calendar days of the results notice; each additional retake costs $125. Certification is valid for 3 years. Fees depend on the program and on AFE membership, so read the current prices on afe.org before you enrol.

Worked examples: how to reason through AFE 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: A building's chiller plant has a measured COP of 4.5. What does this value indicate?

1. The chiller produces 4.5 kW of cooling for every 1 kW of electrical input
2. The chiller operates at 45% of its rated capacity
3. The system's peak demand is 4.5 times the nameplate rating
4. 4.5 gallons of condenser water are circulated per ton of cooling

Answer: A. The chiller produces 4.5 kW of cooling for every 1 kW of electrical input

Explanation:

A is correct. COP compares useful cooling output with the electrical energy put in, using the same units on both sides, so a COP of 4.5 means 4.5 kW of cooling for every 1 kW of electrical input.

B is wrong because COP is a ratio of output to input, not a percentage of rated capacity. C is wrong because peak demand and nameplate rating describe electrical load, not efficiency. D is wrong because condenser water flow per ton of cooling is a flow rate, a different measurement from COP.

Rule to remember: COP is useful output divided by input energy, and a higher value means a more efficient machine.

Example 2

Question: When evaluating capital projects, Facilities Engineers often use a 'payback period' calculation. What does this metric measure?

1. The total lifetime cost of owning an asset
2. The time required for project savings or revenues to recover the initial investment
3. The net present value of future cash flows
4. The internal rate of return on the investment

Answer: B. The time required for project savings or revenues to recover the initial investment

Explanation:

B is correct. Payback period is the time it takes for a project's cumulative savings or revenues to equal the money spent up front.

A describes life-cycle cost, which adds up everything an asset costs over its life rather than timing a recovery. C is net present value, which discounts future cash flows to today's value and gives a dollar amount, not a length of time. D is internal rate of return, a percentage rate, not a time.

Rule to remember: payback answers how soon you get your money back. It says nothing about what happens after that point, so engineers usually read it alongside net present value or internal rate of return.

Example 3

Question: A sprinkler system is classified as 'Light Hazard Occupancy' per NFPA 13. Which type of facility would most likely fall into this classification?

1. Automotive garage
2. Office building
3. Woodworking shop
4. Paint storage warehouse

Answer: B. Office building

Explanation:

B is correct. NFPA 13 sorts occupancies by how much combustible material they hold and how quickly a fire could grow. Offices hold little fuel and have a low chance of a fast, intense fire, which fits Light Hazard.

A, an automotive garage, involves fuels, oils and vehicles, which place it in a higher hazard class. C, a woodworking shop, has dust and large amounts of combustible material. D, paint storage, holds flammable liquids and sits among the most demanding classes.

Rule to remember: the classification follows the contents and activity of the space, not the type of building. Check the current edition of the standard for the exact class definitions.

How to use these practice tests

Start with the official material, because AFE sets the exam rules and the review book that comes with the self-study program. Read the page for your credential on afe.org and note the eligibility option you meet, the passing rule and the retake terms.

Then use our practice sets as a diagnostic. Take AFE Fundamentals & Core Concepts to see where you stand, then work through the topic sets that match your daily work and, more importantly, the ones that do not. Facilities managers often find the energy, safety and capital planning sets less familiar than operations. Try Energy Management & Sustainability, Safety & Risk Management and Project Management & Capital Planning for that.

After each set, write down every question you missed and the rule behind it, then look that rule up in the official book. If you are sitting CPMM, which is open book, practise finding answers quickly rather than memorising. Finish with another pass on your weakest sets. Our questions are written by us and are not real exam questions, so use them to find gaps, not to predict the exam.
