CALGreen · California Green Building Standards Code (CALGreen)

Referenced Organizations and Standards (Chapter 6)

Chapter 6 is the CALGreen look‑up chapter that identifies external standards and ties each standard to the specific code sections that reference it.

Last reviewed: July 6, 2026

Overview

Chapter 6 of the California Green Building Standards Code (CALGreen) lists the organizations and external standards that CALGreen references and maps each standard to the specific code sections that rely on it; see §601.1 for the chapter scope and structure.

This chapter matters because many CALGreen requirements point to technical standards (test methods, product specifications, protocols) rather than reproducing long technical text in the code. Those referenced standards supply the detailed methods designers, contractors and enforcing agencies must follow — for example, ISO 14040/14044 life‑cycle assessment standards used by §5.409.2, and NSF/ANSI 140 for carpet referenced in §4.504.3.

Use Chapter 6 as the look‑up table that connects a standard identifier to the CALGreen provision that requires it (the chapter is organized by promulgating agency and lists the referenced sections). Commissioning and other referenced‑standards material is cross‑referenced elsewhere in the code (see the commissioning references tied to §5.410.2 and the supporting materials in Chapter 8).

Frequently asked questions

Are the external standards in Chapter 6 enforceable?

Yes — when a CALGreen section cites a standard, that standard provides the technical requirement applied to that provision (see §601.1). Some referenced documents or sample standards included for convenience (for example certain commissioning templates) are not part of the enforceable code unless the jurisdiction adopts them; check the specific code cross‑reference.

How do I find which standard applies to a single CALGreen requirement?

Look up the requirement’s code section, then consult Chapter 6’s table to find the standard acronym/number and the promulgating organization; Chapter 6 maps each standard to the exact CALGreen sections that reference it.

Where can I obtain the full text of a referenced standard?

Chapter 6 provides the standard identifier and publisher but not the full text. Obtain the full standard from the issuing organization (ANSI, ISO, ASTM, NSF, etc.) or from libraries/standards vendors; some referenced materials and templates appear in Chapter 8 as convenience documents but may not be binding unless adopted.
