Title 24 · California Energy Code
Reference Appendices (NA6, NA7, NA7.8) used for acceptance and test protocols
If a Code section points to a Reference Nonresidential Appendix (NA6, NA7, NA7.8), you must use that appendix’s calculation or test method and submit the required Certificate of Acceptance (or installation certificate) to the enforcement agency before occupancy — for example, NA6 is used for certain skylight defaults under § 110.6(a)2–4, and NA7 / NA7.8 supply the acceptance tests and reporting formats for HVAC, ducts, and outdoor lighting controls in §§ 120.5, 130.4 and related sections.

What the code requires — 2-4 sentences
The California Energy Code uses the Reference Nonresidential Appendices NA6 and NA7 (and the lighting‑controls testing appendix NA7.8) to provide standardized methods and forms for computing default fenestration metrics and for performing and documenting acceptance testing of systems. When a provision in the body of the Code points to an appendix, that appendix’s test or calculation method must be used (for example, default skylight properties per § 110.6(a)2–4 and acceptance testing for many HVAC, lighting and other systems per § 120.5(a) and § 130.4).
The single most important rule: when the Code references a “Reference Nonresidential Appendix (NA#),” perform the specific test or calculation in that Appendix and provide the corresponding Certificate of Acceptance (or installation certificate) before an occupancy permit is issued.
Requirements in detail
Scope and purpose (what each appendix covers)
Reference Nonresidential Appendix NA6 — provides procedures for calculating default fenestration metrics (examples in the Code: default U‑factor, SHGC, VT for skylights and other fenestration when NFRC ratings are not available). It is invoked in exceptions to the fenestration requirements in § 110.6(a)2–4.
Reference Nonresidential Appendix NA7 — provides the Acceptance Requirements for Code Compliance and the specific test procedures (NA7.x) used to verify equipment and systems (HVAC, duct leakage, DOAS/HRV/ERV, compressors, refrigeration, elevators, compressed air, etc.) before occupancy. Many mandatory acceptance requirements in Part 6 and elsewhere in the Code point to NA7 (for example § 120.5(a) and § 160.3(d)).
Reference Nonresidential Appendix NA7.8 — provides the test procedure for outdoor lighting controls acceptance testing; the Code requires outdoor lighting controls be tested per NA7.8 before occupancy where applicable (see § 130.4 and related subsections).
Decision‑relevant dimensions and values
The table below collects decision thresholds and the Code sections that call the appendices (use the appendix test method named in the Code section).
| Decision dimension / value | How it matters | Appendix or test | Code Reference |
|---|---|---|---|
| Skylight area < 200 ft² | Allows use of NA6 default calculations for U‑factor, SHGC, VT when NFRC is not used | NA6 | § 110.6(a)2–4 |
| Site‑built fenestration (non‑residential) | Must be certified per NA7 before occupancy; matching label certificate required | NA7 (fenestration acceptance) | § 110.6(a)6 |
| Duct leakage ≤ 6% of nominal air handler airflow | New duct systems that meet specific criteria must be sealed and verified by NA7.5.3 test | NA7.5.3 | § 120.5(a) and § 160.3(c)2H |
| Duct test applicability: constant‑volume single‑zone, < 5,000 ft² served, > 25% ducts outdoors/unconditioned | These criteria determine whether the 6% leakage threshold and NA7.5.3 apply | NA7.5.3 | § 120.5(a) / § 160.3(c)2H |
| Outdoor lighting controls | Must be acceptance‑tested per NA7.8 (tests for daylighting, shut‑off, demand response, outdoor controls grouped in NA7.6 & NA7.8) | NA7.8 | § 130.4 / § 130.5 / § 160.5(e) |
| Certified test technician requirements (CMATT / CLCATT) | Certain acceptance tests must be performed by certified technicians and their ID must appear on the Certificate of Acceptance | NA7 (reference for acceptance) and Part 1, § 10‑103 | § 120.5(a); § 160.3(d); § 130.4(c); § 10‑103 |
How the appendices are used in practice
- Where the body of the Code says “shall be tested in accordance with NA7.x” or “default … may be calculated as set forth in NA6,” you must:
- Follow the exact test method or calculation in that NA section; and
- Prepare and submit the required Certificate of Acceptance (or installation certificate) to the enforcement agency before an occupancy permit is issued. See the many body sections that require submission of a Certificate of Acceptance referencing NA7 (for example § 120.5(a) and § 130.4).
Exceptions & special cases
Manufacturer‑certified equipment exception: air economizers installed and factory‑tested/certified by the HVAC manufacturer are not required to undergo the NA7 functional test for air economizers. See the exceptions in § 120.5(a)4.
Healthcare facilities: Many acceptance testing requirements that reference NA7 exclude systems serving healthcare facilities; where healthcare rules apply alternate acceptance/testing requirements or OSHPD rules may take precedence (see exceptions to § 120.5 and other sections).
Fenestration alterations and re‑use: Reinstalled fenestration removed and reinstalled as part of an alteration may be excepted from some labeling/acceptance requirements (see exceptions to § 110.6). However, new site‑built fenestration in nonresidential buildings still requires certification per NA7.
Lighting specific subcases: Daylight responsive, shut‑off, demand response, and outdoor lighting controls are handled under NA7.6 series and NA7.8; certain multifamily common areas have separate cross‑references (see § 130.4 and § 160.5(e)).
Common mistakes
Removing temporary labels on fenestration before inspection. The Code requires a temporary label (or label certificate for site‑built products) not be removed before inspection — see § 110.6(a)5.
Assuming NA6 default values apply to all windows/skylights — NA6 defaults are explicitly invoked only in the circumstances shown in the body of the Code (for example, skylights with less than 200 ft²) — do not apply NA6 where NFRC ratings or other body‑section requirements govern. See § 110.6(a)2–4.
Failing to submit a Certificate of Acceptance (or a properly completed installation certificate) referencing the NA7 acceptance test — many sections state that the Certificate must be submitted to the enforcement agency before occupancy (see § 120.5(a) and § 130.4).
Testing by uncertified personnel: when the Code requires a CMATT or CLCATT under Part 1 § 10‑103, the acceptance testing must be performed by a certified technician and include their certification ID on the Certificate of Acceptance (see § 160.3(d) and § 130.4(c)).
Misinterpreting applicability thresholds (e.g., duct leakage testing criteria such as < 5,000 ft² served or > 25% ducts located outdoors/unconditioned) — confirm the body section first (e.g., § 120.5(a), § 160.3(c)2H) before applying NA7.5.3.
Worked example — small office skylight + duct system
Scenario: A small office installs a new skylight of 150 ft² and a new constant‑volume, single‑zone HVAC system that serves 3,200 ft² of conditioned floor area. Some ductwork runs through an unconditioned attic and accounts for 30% of the total duct surface area.
Steps and how the appendices apply:
Skylight default properties: Because the skylight area is less than 200 ft², the Code allows the use of NA6 default calculation procedures for U‑factor, SHGC, and VT when NFRC ratings are unavailable; follow NA6 for the exact calculation method and document the result as allowed by § 110.6(a)2–4. (Note: the specific numeric defaults or formulas in NA6 are not included in the retrieved excerpts, so consult Appendix NA6 directly for the numeric procedure.)
Duct leakage testing: The duct system is a constant volume single‑zone system, serves < 5,000 ft², and > 25% of the duct surface area is outdoors/unconditioned — so the duct system meets the criteria to be tested to a leakage rate not greater than 6% of the nominal air handler flow using the NA7.5.3 test procedure and report. Perform NA7.5.3 testing and include results on the Certificate of Acceptance required by § 120.5(a).
Documentation and occupancy: Before an occupancy permit is granted, submit the Certificate of Acceptance showing the NA6 computation for the skylight (if used) and the NA7.5.3 duct leakage test result in accordance with the Code sections that require submission (for fenestration § 110.6(a)6 and for mechanical acceptance § 120.5(a)). If any acceptance testing must be done by a certified acceptance test technician (CMATT/CLCATT), ensure that certification ID is on the certificate per § 10‑103 rules.
(If you need the actual NA6 default numeric values or the exact test procedure steps from NA7.5.3/NA7.8, those are inside the Appendices themselves; the excerpts we have reference the appendices but do not reproduce the detailed numeric tables or step‑by‑step procedures. Consult NA6 and NA7.5.x/NA7.8 text for the exact formulas, instrumentation, and reporting formats.)

Frequently asked questions
What exactly does NA6 contain?
NA6 contains the procedures and default calculations used where NFRC or other rating methods are not used for fenestration metrics (U‑factor, SHGC, VT) and is specifically called out for limited skylight and alteration cases in the body of the Code — see § 110.6(a)2–4. For the numeric formulas or tables, consult Appendix NA6 directly; the body sections only reference it.
When must I submit a Certificate of Acceptance?
Whenever a Code section says “shall be certified as meeting the Acceptance Requirements … as specified by Reference Nonresidential Appendix NA7,” a Certificate of Acceptance must be submitted to the enforcement agency before an occupancy permit is granted (examples include § 120.5(a) for mechanical systems and § 130.4 for lighting controls).
Do I always need a certified tester (CMATT / CLCATT)?
No — only when the particular acceptance testing requirement in the body of the Code references the Part 1 certification requirement (e.g., § 160.3(d) and § 130.4(c) indicate that certain acceptance tests must be performed by certified technicians and that the technician’s certification ID be on the Certificate of Acceptance). Check the specific body section that invokes NA7.x.
Are there exceptions for factory‑calibrated equipment?
Yes. For example, air economizers that are installed and factory‑certified by the HVAC manufacturer are exempt from the NA7 functional testing portion for air economizers per the exception in § 120.5(a)4.
Where do I find the exact NA7.8 test steps for outdoor lighting?
The Code body requires that outdoor lighting controls be tested per NA7.8 (see § 130.4 and related sections). The step‑by‑step test method and reporting format are in Appendix NA7.8 itself — consult that appendix for instrumentation, sampling, and reporting details.
