Introduction
This CEA Certification Exam format for 2026/2027 reflects the standardized assessment administered
by the Association of Energy Engineers (AEE) to evaluate competency in commercial and industrial
energy auditing practice. The exam measures knowledge of audit protocols, building systems
evaluation, energy accounting, economic analysis, instrumentation use, code compliance, and
scenario-based decision-making essential for delivering accurate, actionable energy audit reports. The
official AEE CEA certification exam consists of exactly 120 multiple-choice questions administered in
an open-book, four-hour testing window.
Exam Structure
• 120 multiple-choice questions (100 scored + 20 unscored pretest items)
• Single-best-answer and scenario-based energy auditing items
• Focus on evidence-based audit methodologies and ASHRAE Standard 211 application
• Total testing time: 4 hours (open-book format)
Answer Format
All correct answers are presented in bold and green text. Each question appears in bold font, and
all rationales explaining audit methodologies, engineering principles, economic calculations, and
scenario-based reasoning are written in italic font.
Section 1: Energy Audit Procedures & Protocols
Questions 1-15
1. According to ASHRAE Standard 211, what is the minimum level of energy audit
required for buildings under 50,000 square feet?
A. Level 1 only ✓
B. Level 2
C. Level 3
D. No minimum requirement
Rationale: ASHRAE Standard 211 establishes Level 1 as the minimum audit for buildings
under 50,000 sq ft. This preliminary energy use analysis provides basic assessment of energy
efficiency opportunities suitable for smaller facilities.
2. What is the primary purpose of a Level 2 energy audit according to ASHRAE
Standard 211?
A. To provide investment-grade analysis
Page 3 of 35
, CEA Certification Exam – 2026/2027
B. To identify energy conservation measures with detailed cost-benefit analysis ✓
C. To perform preliminary screening only
D. To monitor real-time energy consumption
Rationale: A Level 2 energy audit identifies and analyzes energy conservation measures with
detailed cost-benefit calculations, providing sufficient detail for implementation decisions
without the extensive data collection of Level 3 audits.
3. During an energy audit walk-through, what should be documented for each major
energy-consuming system?
A. Manufacturer name only
B. Nameplate data, operating hours, control sequences, and condition ✓
C. Age of equipment only
D. Energy costs only
Rationale: Comprehensive documentation during walk-throughs includes nameplate data
(capacity, efficiency ratings), operating schedules, control strategies, maintenance condition,
and any observed operational issues affecting energy performance.
4. What is the recommended approach for establishing baseline energy consumption?
A. Use one month of utility data
B. Analyze at least 12-24 months of utility data ✓
C. Estimate based on building size
D. Use regional averages
Rationale: Establishing an accurate baseline requires analyzing 12-24 months of utility data to
capture seasonal variations, occupancy patterns, and operational changes. This provides the
foundation for meaningful energy savings calculations.
5. Which document must be reviewed before conducting an energy audit?
A. Employee handbook only
B. Building drawings, O&M manuals, and utility bills ✓
C. Fire safety plan only
D. Insurance policies
Rationale: Pre-audit preparation requires reviewing building documentation including
architectural and mechanical drawings, O&M manuals, equipment specifications, utility bills,
and any previous energy studies to inform the audit approach.
6. What is the difference between a Level 2 and Level 3 energy audit?
