Confirm You Are Registering for Exam 78

ICC offers several energy-related certifications whose names sit close together in the catalog. Candidates occasionally buy the wrong product because the titles look alike. Three things to keep straight:

  • Exam 78 is Commercial Energy Plans Examiner. This is the exam this cheat sheet covers.
  • Exam 77 is Commercial Energy Inspector, a different credential focused on field inspection rather than plan review.
  • The combined Commercial Energy Inspector/Plans Examiner listing and the ASHRAE 90.1 exam are separate products. Do not substitute them for Exam 78.
Check the exam number, not just the title: The exam number and code edition on your receipt should read Exam 78 and the edition you plan to study. A wrong purchase wastes the fee and study time, so confirm both before checkout and again on your confirmation email.

If you are still deciding between credential paths, the overview pages What Is CEPE? and CEPE Certification explain how the examiner credential differs from its inspection-side neighbors.

The Five Study Domains in One Pass

ICC's 2021 Commercial Energy Plans Examiner study guide organizes its preparation material under five headings. These are unweighted curriculum headings for the still-listed 2021 exam. They are not a verified weighted exam blueprint, and no official domain percentages are published here, so do not assume equal weighting. Use them to organize your review, then read the full CEPE domains guide for topic-level depth.

Domain 1: General Plan Review Issues

This is the examiner's procedural backbone: what a reviewer checks first, and how scope and compliance paths are determined before any technical calculation begins.

  • Scope and applicability of the energy code to the project type
  • What documentation the code requires on construction documents
  • Compliance path selection and how it changes what you verify
  • Definitions and administrative provisions that frame every other domain

Domain 2: Building Envelope

The envelope questions reward careful reading of tables and conditions. Expect to compare submitted assemblies against prescriptive requirements.

  • Insulation requirements by climate zone and assembly type
  • Fenestration performance requirements and how they are documented
  • Air leakage and continuous air barrier provisions
  • How to read a code table correctly when conditions or footnotes modify the value

Domain 3: Mechanical Systems

Mechanical review is about whether the submitted system meets efficiency, control, and distribution requirements on paper.

  • Equipment efficiency requirements and where they are listed
  • HVAC controls, including setback and shutoff-type provisions
  • Duct and piping insulation and sealing requirements
  • System sizing and ventilation-related energy provisions

Domain 4: Electrical Power and Lighting Systems

Lighting review blends prescriptive power limits with control requirements, and plan sets must show enough information to verify both.

  • Interior and exterior lighting power allowances
  • Lighting control requirements and how they appear on plans
  • Electrical power and metering provisions
  • Which lighting information must be shown on submitted documents

Domain 5: Building Service Water Heating Systems and Equipment

The smallest-sounding domain still produces questions you should not skip. Treat it as a quick, high-return review block.

  • Service water heating equipment efficiency requirements
  • Piping insulation and system layout provisions
  • Controls and recirculation-related requirements
  • Pool and spa provisions where the code addresses them

Code Editions: The Fact That Sinks Careless Candidates

ICC's current national exam list, updated January 12, 2026, shows both the 2021 and 2024 code editions for Exam 78, with 2024 as the latest listed edition. That matters more than any other single logistics fact, because code requirements change between editions, and a question written against one edition can have a different correct answer under the other.

Key Takeaway

Pick the code edition first, then buy materials. Every reference book, practice question and flashcard set should match the edition printed on your exam registration. An edition-specific weighted exam outline was not verified, so do not trust any source that claims exact percentages for a given edition.

The five domain headings above come from the 2021 study guide. If you register for the 2024 edition, use them as a topic map but work from the 2024 code text itself. The CEPE study guide walks through building a plan around your registered edition.

Scoring and Question Format

Three facts cover almost everything candidates ask about scoring:

  1. Format: 70 multiple-choice questions, each with four options and exactly one correct answer.
  2. Passing standard: a scaled score of 75. This is not 75% correct. Scaled scoring adjusts for differences between exam forms, so you cannot convert a raw count of correct answers into a pass or fail by simple division.
  3. Time: 3 hours 30 minutes for the full exam. The study guide's two-hour length refers to the length of the online course, not exam time. Do not confuse the two.

Because the exam is code-based and, depending on delivery, typically open-book within ICC's reference rules, the skill being tested is navigation and application rather than memorization. Fast, accurate lookup in the code text is the practical skill. Candidates who tab and annotate their permitted references (within ICC policy) tend to spend their time on reasoning instead of searching.

For more on how the score works, read the CEPE passing score explainer. For a realistic look at difficulty without invented numbers, see how hard the CEPE exam is, and for what published data does and does not show, the CEPE pass rate article.

Registration, Delivery and Reference Logistics

Registration and validity

The exam fee is US$320. Exam purchases remain valid for 365 days, which gives you a full year to schedule and sit the exam. When purchasing, select the correct examination, the code edition, and the delivery method. Those three selections are where most avoidable errors occur.

Delivery options

ICC PRONTO uses Meazure Learning's ProctorU platform. ICC's current PRONTO page describes live remote proctoring and test-center options, subject to the specific examination selected and scheduling availability. Do not assume both options are open for your chosen exam and date. Confirm availability in the registered exam listing at the time you schedule. Scheduling windows and deadlines are covered in the CEPE exam dates guide.

Allowed references and calculators

Authorized reference materials and calculator rules are set by ICC's administrative policies and can differ by delivery method. Read the policy page and the exam-specific listing before exam day, then prepare your references accordingly. Never rely on a forum post or a colleague's memory for what is permitted.

Pre-exam logistics checklist: Confirm the exam number (78), the code edition, the delivery method, the authorized reference list, and the calculator policy. Then check your identification and testing environment requirements for the delivery option you chose. Five minutes of verification can protect a US$320 purchase.

After You Pass: Renewal Facts

Certification renewal runs on a three-year cycle. For one certification, ICC's Credentialing Renewal Bulletin, which carries a cover publication date of January 6, 2026, requires 1.5 CEUs, including at least 0.8 CEUs from Part 1 activities. The listed renewal fees are US$105 for members and US$130 for nonmembers.

Two cautions. First, these are renewal fees, not exam fees, and should never be added to or confused with the US$320 exam cost. Second, requirements can differ when you hold multiple certifications or when ICC publishes a newer bulletin, so check the current bulletin for your own situation rather than treating these figures as permanent.

If you are weighing long-term value, the ROI analysis puts renewal obligations in context with career benefits.

Who Uses a Commercial Energy Plans Examiner

The plans examiner role sits where energy code compliance meets the permitting process. Typical settings include:

  • Municipal and county building departments that review commercial permit submittals for energy code compliance.
  • Third-party plan review firms contracted by jurisdictions that lack in-house energy expertise.
  • State or regional code offices that support or oversee local enforcement.
  • Design and consulting firms whose staff benefit from understanding exactly how reviewers read an energy submittal.

Because plan review is document-based, the work rewards a methodical reading habit: verifying that what is drawn, scheduled and calculated agrees with what the code requires. Salary and job-market specifics vary by region and employer, and this article does not cite figures. For a qualitative treatment, see the CEPE salary guide and the CEPE jobs overview.

A Domain-Ordered Review Sequence

One short scheduling idea tied directly to the domains: start with Domain 1, because its administrative and scope concepts frame how you read everything else, and finish with the shorter Domain 5 as a confidence-building review. Put the table-heavy envelope and lighting domains in the middle, when your code-navigation habits are warm.

Week 1

General Plan Review Issues

  • Learn scope, applicability and compliance-path logic
  • Tab the administrative chapters of your registered edition
Week 2

Building Envelope

  • Practice reading climate-zone tables and footnotes
  • Work fenestration and air-barrier questions
Week 3

Mechanical Systems

  • Review efficiency tables, controls and insulation provisions
Week 4

Electrical Power and Lighting, then Service Water Heating

  • Drill lighting power and control requirements
  • Finish with water heating, then take a timed mixed set at the practice test site

Adjust the pace to your own experience. A working inspector may compress the envelope week, while a candidate new to energy code may need longer on Domain 1. The CEPE training overview compares ways to structure that learning.
