1According to the IECC Commercial Provisions, which buildings are required to comply with the commercial energy code?

A.Only buildings over 50,000 square feet

B.All commercial buildings and residential buildings over three stories above grade plane

C.Only office buildings and retail spaces

D.Only buildings that use more than 100 kW of electrical service

Explanation: Per IECC C101.4, the commercial provisions apply to all commercial buildings as well as residential buildings that are more than three stories in height above grade plane (such as mid- and high-rise apartments and hotels). Low-rise residential buildings follow the IECC residential provisions instead. Exam tip: Memorize the three-story dividing line between residential and commercial provisions — it is a common scope question on Exam 77.

2Which of the following buildings is EXEMPT from the IECC commercial energy code?

A.A 6-story hotel

B.A 50,000 square foot warehouse with conditioned office space

C.A low-energy building where the peak design energy usage is less than 3.4 Btu/h-ft2 or 1.0 W/ft2 of floor area

D.A 3-story mixed-use retail and apartment building

Explanation: Per IECC C101.4.1, low-energy buildings with a peak design energy usage less than 3.4 Btu/h-ft2 or 1.0 W/ft2 of floor area for space conditioning purposes are exempt from compliance. This exemption covers buildings that inherently use very little conditioning energy. Exam tip: Know the three main exemptions — low-energy buildings, buildings in which no conditioning is provided, and equipment buildings that meet limited criteria.

3When an addition is made to an existing commercial building, which provision of the IECC applies to the addition?

A.The addition is exempt from the energy code

B.Only the addition must comply with the requirements for new construction

C.The entire building, including existing portions, must be brought into compliance

D.Only the building envelope of the addition must comply

Explanation: Per IECC C502.1, additions to existing buildings must comply with the requirements of the code for new construction, but the existing building is not required to be brought into compliance. This encourages improvements without penalizing pre-existing construction. Exam tip: Remember the distinction between additions (must meet new-construction requirements for the added portion), alterations (must meet specific requirements for the altered elements), and repairs (generally exempt).

4Which of the following is considered an alteration under the IECC that must comply with the code?

A.Replacing a broken window with one of identical U-factor and SHGC

B.Repainting a conditioned office space

C.Replacing a rooftop HVAC unit with a new higher-capacity unit

D.Replacing broken ceiling tiles

Explanation: Per IECC C503, replacing an HVAC unit is an alteration that triggers compliance — the new equipment must meet the minimum efficiency requirements of the code. Replacement of a window with an identical unit and simple cosmetic repairs are typically treated as repairs, not alterations. Exam tip: HVAC equipment replacements almost always trigger compliance with current minimum efficiency tables (C403).

5A change of occupancy from a warehouse (unconditioned) to an office (conditioned) space triggers which IECC requirement?

A.No compliance is required because it is an existing building

B.The space must comply with the provisions for new construction

C.Only lighting must comply

D.Only the HVAC system must comply

Explanation: Per IECC C505, a change of occupancy or use that results in a space becoming conditioned must comply with the provisions for new construction. This includes envelope, mechanical, service water heating, and lighting. Exam tip: Change-of-occupancy triggers are frequently tested — if a space moves from unconditioned to conditioned, all applicable provisions apply.

6Which document is the primary alternate compliance path to the IECC commercial provisions?

A.ASHRAE Standard 62.1

B.ASHRAE Standard 90.1

C.ASHRAE Standard 55

D.ASHRAE Standard 189.1

Explanation: Per IECC C401.2, compliance with the commercial provisions can be demonstrated by meeting either the IECC requirements or ANSI/ASHRAE/IES Standard 90.1. Standard 90.1 is the long-standing commercial energy standard and is referenced as an equivalent alternate compliance path. Exam tip: Know what each ASHRAE standard covers — 62.1 is ventilation, 55 is thermal comfort, 189.1 is green buildings, and 90.1 is energy efficiency.

7The IECC divides the United States into how many climate zones for energy code compliance purposes?

A.5 climate zones

B.7 climate zones

C.8 climate zones

D.10 climate zones

Explanation: Per IECC Chapter 3 and Figure C301.1, the United States is divided into 8 climate zones (numbered 1 through 8), with moisture designators A (moist), B (dry), and C (marine). The climate zone determines almost every envelope and equipment requirement. Exam tip: Always identify the project's climate zone first — it drives insulation R-values, fenestration U-factors, and SHGC requirements.

8Which code section contains the definitions used throughout the IECC commercial provisions?

A.IECC Chapter 1

B.IECC Chapter 2

C.IECC Chapter 4

D.IECC Chapter 5

Explanation: IECC Chapter 2 contains the definitions used in both the residential and commercial provisions of the code. Key definitions include conditioned space, semiheated space, fenestration, and thermal envelope. Exam tip: Tab Chapter 2 in your codebook — definitions questions reference terms like 'conditioned space' and 'building thermal envelope' frequently.

9Which of the following spaces is classified as 'conditioned space' under the IECC?

A.An enclosed space with a design heating or cooling system that maintains an interior temperature

B.A garage that is naturally ventilated year-round

C.An attic that is separated from the occupied space by insulation

D.A crawlspace with no mechanical system

Explanation: Per IECC Chapter 2, 'conditioned space' is an area, room or space that is enclosed within the building thermal envelope and that is directly or indirectly heated or cooled. Any space with an installed design heating or cooling system is conditioned. Exam tip: The determination of conditioned vs. unconditioned space is the first step in verifying the envelope scope — all envelope requirements apply only to the boundary of conditioned space.

10Under the IECC, what is the minimum required insulation R-value for above-deck roof insulation in Climate Zone 4 for non-residential buildings?

A.R-20

B.R-25

C.R-30

D.R-35

Explanation: Per IECC Table C402.1.3, above-deck insulation for roofs in Climate Zone 4 (non-residential) requires a minimum of R-30 continuous insulation. The exact values vary by climate zone — zones 1-2 require R-25, zones 3-4 require R-30, zones 5-7 require R-30 or R-35, and zone 8 requires R-35. Exam tip: Always confirm the climate zone first, then look up the correct row in Table C402.1.3.

About the ICC 67 Exam

The ICC Commercial Energy Inspector (67) exam is administered by the International Code Council and certifies individuals to inspect commercial buildings for compliance with the International Energy Conservation Code (IECC) Commercial Provisions. The open-book exam tests knowledge of building envelope (insulation, fenestration, air leakage), mechanical systems (HVAC efficiency, economizers, ducts, controls), service water heating, electrical power and interior/exterior lighting power density, and commissioning. Candidates may use the 2024 IECC as the primary reference, with ASHRAE 90.1 available as an alternate compliance path. ICC 67 certification is widely recognized by city, county, and state building departments and is a core credential for code officials specializing in commercial energy enforcement.

ICC 67 Study Tips from Top Performers

1Tab your 2024 IECC Commercial Provisions extensively — mark Table C402.1.3 (envelope prescriptive R/U-values by climate zone), C402.5 (air leakage), C403.3.2 (HVAC equipment efficiency), C404 (service water heating), C405.3.2 (interior LPD), C405.4.2 (exterior LPD), and C408 (commissioning)

2Memorize the compliance path structure — prescriptive (C402-C405), total building performance (C407), or ASHRAE 90.1 as an alternate per C401.2. Exam scenarios often specify which path the designer chose, which changes which tables you must consult

3Master climate zone lookups — the exam gives a city or zone number and you must pull the correct envelope value from Table C402.1.3. Zones 1-8 drive nearly every envelope question, so drill the table until you can find values in under 10 seconds

4Know the lighting power density method — interior LPD is calculated either by Building Area Method (C405.3.2(1)) or Space-by-Space Method (C405.3.2(2)). Understand the watts-per-square-foot allowances and when automatic controls are required per C405.2

5Study HVAC efficiency tables and economizer requirements — Table C403.3.2 lists minimum efficiencies for unitary AC, heat pumps, boilers, and chillers. Economizer rules (C403.5) depend on climate zone and equipment capacity. Also know fan power limits (C403.8) and DCV triggers (C403.7.1)

6Do not overlook Service Water Heating and Additional Efficiency — even though SWH is only ~5% of the exam, C404 and C406 (additional efficiency packages) questions are easy points if you have tabbed the pipe insulation, heat trap, and additional efficiency credit requirements

Frequently Asked Questions

What score do I need to pass the ICC 67 exam?

The ICC 67 Commercial Energy Inspector exam requires a scaled score of 75 to pass, which corresponds to approximately 75% of questions answered correctly. If you pass, you see 'PASS' on your results — no numerical score is shown for passing candidates. If you fail, you receive a diagnostic report showing your performance by content area so you know which domains to restudy. ICC uses scaled scoring set by the ICC Exam Development Committee to normalize difficulty across exam forms.

Is the ICC 67 exam open-book?

Yes, the ICC 67 exam is open-book. You may bring the 2024 International Energy Conservation Code (IECC) Commercial Provisions as your primary reference. ASHRAE 90.1 may be used as an alternate compliance path reference. You can tab, highlight, and annotate your codebooks, but sticky notes and loose inserts are not permitted. With only 2 minutes per question on average, you must be highly familiar with C402-C408 layouts and able to locate prescriptive tables quickly.

How hard is the ICC 67 exam?

The ICC 67 is moderately challenging. The Building Envelope (32%) and Mechanical Systems (26%) sections dominate the test, and both require rapid table lookups for insulation R-values, U-factors, equipment efficiencies, and fan power limits. Climate-zone dependent values are a major source of errors — answers change depending on which zone the scenario describes. Calculation questions for lighting power density and envelope compliance are common. Candidates who drill timed practice exams and thoroughly tab Tables C402.1.3, C403.3.2, and C405.3.2 have the highest success rates.

What codebook do I need for the ICC 67 exam?

The current ICC 67 exam is based on the 2024 International Energy Conservation Code (IECC) Commercial Provisions (chapters C1-C6). You can purchase the IECC from the ICC store or use a tabbed hard copy. ASHRAE Standard 90.1 may also be used as an alternate compliance path reference under IECC C401.2. Always confirm the code edition on the ICC exam bulletin before purchasing — ICC periodically updates to newer editions. The IRC and IBC are not required references for this exam.

What jobs can I get with ICC 67 certification?

ICC 67 certification qualifies you for commercial energy inspector positions with city, county, and state building departments, as well as third-party inspection firms. Average salaries range from $60,000-$95,000 depending on location and experience. Many jurisdictions require ICC certification as a condition of employment for energy code enforcement. The 67 is often combined with the Commercial Energy Plans Examiner (68) credential or with B2 (Commercial Building Inspector) to expand scope and unlock higher-paying combination roles.

How do I prepare for the ICC 67 exam?

Start by obtaining the 2024 IECC Commercial Provisions and reading chapters C1-C6 in full. Tab Tables C402.1.3 (envelope prescriptive), C403.3.2 (equipment efficiency), C404 (water heating), C405.3.2 (interior LPD), and C405.4.2 (exterior LPD). Practice climate-zone lookups until instant. Use a self-paced study guide and complete timed 60-question mocks until you can finish in under 90 minutes. Focus heavily on Building Envelope (32%) and HVAC (26%) since they drive more than half the score.
