AEE AEE Energy Certifications License: Complete Roadmap
Follow this path to organize your licensing and exam preparation
Exam Scope and Energy FundamentalsYou are here
Start with the open-book exam structure, 14 mandatory subjects, unit conversions, benchmarking, policies, standards, and energy-management frameworks.
Audits, Tariffs, and Economics
Practice utility bill analysis, demand charges, load factor, audit instrumentation, baselines, simple payback, NPV, and life-cycle cost concepts.
Major Building Systems
Spend the largest block on HVAC, building envelope, lighting, electrical power, motors, VFDs, automation, controls, and commissioning.
Thermal, Industrial, Storage, and Generation Systems
Review boiler and steam systems, compressed air, process loads, energy storage, distributed generation, renewables, and CHP applications.
Performance Contracts and Timed Mixed Review
Finish with ESPC, M&V options, normalization, adjustments, and timed mixed sets using only references you can navigate quickly.
Can You Take the AEE CEM Exam?
Check if you meet the basic eligibility requirements
- •Submit the appropriate CEM application through AEE's current process.
- •Follow AEE's current candidate handbook for approval, scheduling, allowed references, calculator rules, and identification requirements.
- •Bring a hand calculator; the BoK states that computers, tablets, and cell phones are not allowed during the exam.

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
What's Next After the AEE CEM?
After passing the AEE CEM, you can pursue these career paths
Certified Measurement & Verification Professional (CMVP)
Build deeper capability in M&V planning, savings verification, baselines, and performance reporting.
Certified Energy Auditor (CEA)
Focus on audit planning, field investigation, instrumentation, and energy conservation measure development.
Certified Building Commissioning Professional (CBCP)
Extend CEM knowledge into commissioning, functional performance testing, and systems optimization.
