Exam overview and details

The Certified Energy Manager (CEM(R)) credential, administered by the Association of Energy Engineers (AEE), is the premier global certification for professionals in energy management and efficiency. It validates a comprehensive understanding of energy procurement, utility rate structures, building systems optimization, energy auditing, performance contracting, and financial analysis of energy projects. Achieving the CEM designation signifies mastery of the technical, economic, and regulatory principles required to develop, implement, and manage successful energy programs. Recognized by corporations, government agencies, and utilities worldwide, the CEM is often a prerequisite for leading major energy initiatives and is a cornerstone credential for professionals aiming to drive organizational sustainability, reduce operational costs, and ensure regulatory compliance. It represents a commitment to excellence and positions the holder as a trusted expert in a critical and evolving field.

Sample Questions

Choose an answer and explore the explanation to see how practice works.

Energy Audits and Instrumentation

An office audit compares two years of utility bills. Year 2 used 8% less electricity, but occupancy fell by 20% and cooling degree-days were 12% lower. Which conclusion is most defensible?

Energy Rates, Tariffs and Supply Options

A campus utility bill has an energy charge, facilities charge, demand charge, and a penalty when monthly power factor is below 0.90. The electrical shop proposes capacitors. Which billing line should the CEM examine to estimate avoided cost most directly?

Industrial Systems

A bottling plant compressed-air system runs at 118 psig because one legacy machine occasionally faults below 105 psig. Most equipment needs only 85 psig. Which action should be evaluated before raising compressor capacity?

Operations, Maintenance and Commissioning

A new library opened six months ago. The design intent required quiet reading rooms, demand-controlled ventilation, and daylight dimming. Occupants complain about stuffy rooms and lights cycling near windows. Which commissioning document is most useful for deciding whether the systems meet the owner's stated needs?

Electrical Power Systems and Motors

A facility has a 900 kW real-power load at 0.78 lagging power factor. The utility bills kVA demand above 0.90 power factor equivalent. Which corrective action most directly reduces billed kVA without reducing production load?
