CALGreen · California Green Building Standards Code (CALGreen)
How CALGreen references the California Energy Code and scope for nonresidential buildings
CALGreen’s § 5.201.1 tells you that mandatory energy requirements for nonresidential buildings are set by the California Energy Commission (the California Energy Code). In practice, use CALGreen to identify which provisions apply to your building and then follow the Energy Code for the actual energy metrics, testing, and compliance documentation.
Last reviewed: July 6, 2026
What the code requires — in plain English
CALGreen defers the mandatory energy efficiency requirements for nonresidential buildings to the California Energy Code — that is, CALGreen does not re‑state or replace the mandatory energy standards but directs users to the Energy Code adopted by the California Energy Commission. See § 5.201.1.
For mandatory energy efficiency in CALGreen’s nonresidential chapter, follow the California Energy Code adopted by the California Energy Commission (per § 5.201.1).
Requirements in detail
Key point — what § 5.201.1 says
- § 5.201.1 (Scope) states that for the purposes of mandatory energy efficiency standards in CALGreen, the California Energy Commission will continue to adopt mandatory building standards (i.e., the California Energy Code). § 5.201.1 is the controlling CALGreen provision on scope.
How CALGreen fits with the Energy Code (decision dimensions)
| Decision question | What to do / value | Code Reference |
|---|---|---|
| Which authority sets mandatory energy standards for nonresidential buildings? | California Energy Commission — the Energy Code governs mandatory energy efficiency requirements. | § 5.201.1 |
| Where in CALGreen is the nonresidential energy chapter organized? | Division 5.2 — Energy Efficiency of Chapter 5 (nonresidential mandatory measures) — CALGreen’s Division points to the Energy Code for mandatory energy rules. | Chapter/Division headings (Chapter 5, Division 5.2) |
| What about performance or functional testing for systems? | Functional performance testing requirements refer back to the California Energy Code for procedures and compliance (CALGreen cross‑references that requirement). | § 5.410.2.1 (Informational note) |
| Which CALGreen provisions help you determine applicable sections or agency jurisdiction? | Use Chapter 1 administration (e.g., state‑agency scope and matrix adoption tables) to identify which CALGreen provisions apply to a particular occupancy and which agency enforces them. | § 101.3.1 and matrix adoption tables (Chapter 1 and Chapter 5 matrices) |
Practical implications
- CALGreen does not duplicate mandatory energy prescriptive values or trade‑offs; it points designers, builders, and enforcement authorities to the California Energy Code for mandatory energy metrics, prescriptive measures, compliance paths, and documentation requirements. § 5.201.1 is the explicit cross‑reference.
- Other CALGreen obligations (commissioning, documentation, etc.) may require coordination with Energy Code testing and verification procedures — see CALGreen commissioning references and the informational note about functional testing.
Exceptions & special cases
- CALGreen’s energy scope statement in § 5.201.1 does not list exceptions to the Energy Code itself; any exceptions to energy requirements must be taken from the California Energy Code or from CALGreen sections that explicitly address a specific measure. The text of § 5.201.1 only assigns adoption authority to the California Energy Commission.
- For other CALGreen provisions that intersect with energy compliance (for example, commissioning), CALGreen includes exceptions for certain low‑risk project types (commissioning exceptions such as dry storage warehouses and small accessory conditioned spaces) — those exceptions are in the CALGreen commissioning reference material and glossary rather than in § 5.201.1 itself.
- Use the Chapter 1 state‑agency tables and matrix to check whether a particular occupancy is subject to CALGreen measures adopted by a given state agency; the matrix indicates adoption scope and exceptions for agency‑regulated buildings.
Common mistakes
- Treating CALGreen’s Division 5.2 as containing the definitive numeric energy standards. (Wrong: § 5.201.1 directs you to the California Energy Code for mandatory energy standards.)
- Assuming CALGreen’s procedural items (commissioning, testing, documentation) replace Energy Code testing protocols — in fact, CALGreen instructs that functional performance testing must comply with the California Energy Code where applicable.
- Failing to consult the Chapter 1 matrix and agency scope when a building is state‑regulated — that table determines whether a particular CALGreen section applies to a given occupancy.
- Relying on CALGreen for specific energy compliance calculations (prescriptive U‑factors, lighting power allowances, HVAC efficiencies) — those numeric compliance details are found in the California Energy Code (not restated in § 5.201.1).
Worked example — applying § 5.201.1 (concrete scenario)
Scenario: New single‑tenant office building, conditioned floor area = 25,000 ft².
Step 1 — Identify jurisdiction and enforcing agency:
- Confirm occupancy and whether any state agency has authority (use § 101.3.1 and the Chapter 5 matrix).
Step 2 — Determine applicable energy standards:
- Because § 5.201.1 assigns mandatory energy efficiency standards to the California Energy Code, apply the energy requirements adopted by the California Energy Commission to the building (i.e., follow the Energy Code compliance paths, forms, and numeric requirements). CALGreen itself does not supply the prescriptive energy numeric tables; it defers to the Energy Code.
Step 3 — Coordinate CALGreen admin and verification items:
- If CALGreen commissioning, functional testing, or documentation requirements apply to this project, perform functional performance testing in accordance with the California Energy Code as noted in CALGreen’s commissioning/functional testing guidance. (See the informational note referencing Energy Code compliance for testing.)
Note: This worked example uses § 5.201.1 as the rule that determines which set of mandatory energy standards you must follow. The specific numeric energy thresholds and compliance forms are in the California Energy Code itself (refer to the Energy Code publications for those values).
Related provisions
- § 5.201.1 — Scope: California Energy Code governs mandatory energy efficiency standards for CALGreen nonresidential measures.
- § 101.3.1 — State‑regulated buildings and scope (identifies where energy standards and agency enforcement are described).
- § 5.410.2.1 — Informational note: Functional performance testing for HVAC and lighting controls must be performed in compliance with the California Energy Code.
- Matrix adoption tables (Chapter 5) and Chapter 1 guidance — use these to determine which CALGreen measures apply and which agency enforces them.
- Commissioning reference / glossary (CALGreen Cx reference) — contains commissioning scope and exceptions (e.g., dry storage warehouses) that intersect with energy testing and verification.

Glossary:
Acceptance Criteria— The conditions that must be met for systems or equipment to meet defined and expected outcomes.
Commissioning (Cx)— Building commissioning as required in this code involves a quality assurance process that begins during design and continues to occupancy. Commissioning verifies that the new building operates as the owner intended and that building staff are prepared to operate and maintain its systems and equipment. Exceptions are allowed for dry storage warehouses of any size and conditioned spaces under 10,000 square feet accessory to them; and for tenant improvements under 10,000 square feet within a larger space.
Owner— The individual or entity holding title to the property on which the building is constructed.
Commissioning Coordinator— The person who coordinates the commissioning process. This can be either a third-party commissioning provider or an experienced member of the design team or owner in-house staff member.
Commissioning Team— The key members of each party involved with the project designated to provide insight and carry out tasks necessary for a successful commissioning project. Team members may include the commissioning coordinator, owner or owner’s representative, building staff, design professionals, contractors or manufacturer’s representatives and testing specialists.

Frequently asked questions
Who actually writes the mandatory energy rules that apply to a new commercial building in California?
The California Energy Commission adopts the mandatory energy rules (the California Energy Code); CALGreen’s § 5.201.1 directs users to those Energy Code standards.
If CALGreen has an energy section (Division 5.2), do I follow CALGreen or the Energy Code?
For mandatory energy efficiency, follow the California Energy Code — CALGreen’s energy division defers mandatory numeric standards to the Energy Code under § 5.201.1.
Does CALGreen require any testing or commissioning that interacts with the Energy Code?
Yes — CALGreen’s functional performance testing and commissioning requirements reference compliance with the California Energy Code for HVAC and lighting controls testing (see § 5.410.2.1 informational note).
Where do I look to see whether a specific CALGreen measure applies to my project type?
Use Chapter 1 (agency scope) and the Chapter 5 matrix adoption tables to determine which CALGreen provisions apply and which agency enforces them.
Are there CALGreen exceptions that let me skip Energy Code testing?
CALGreen’s § 5.201.1 does not create exceptions to the Energy Code. Some CALGreen provisions (like commissioning) include their own limited exceptions (e.g., certain warehouse/tenant‑improvement thresholds) — see the commissioning reference glossary for those specifics.
