CALGreen · California Green Building Standards Code (CALGreen)

What does Section 601.1 list and how do I use the Chapter 6 table of referenced standards?

Chapter 6 is a lookup table: it lists the standards and the agency that publishes them, and shows which CALGreen sections reference each standard (see **§ 601.1**). Use Chapter 6 to identify the standard name/number and the CALGreen provision that uses it, then read that provision to see the actual requirement. Some appendix lists are provided only for convenience and are enforceable only if your local jurisdiction has adopted them.

What the code requires — 2-4 sentences

§ 601.1 says the Chapter 6 tables list the organizations and the standards that are referenced elsewhere in CALGreen and that the standards are grouped by the promulgating agency. Use Chapter 6 as a lookup to find the standard acronym/number, the standard name/title, and the section(s) of CALGreen that reference that standard. § 601.1 is the controlling rule for what Chapter 6 contains.

Use Chapter 6 as a lookup table: it tells you who issued a standard, the standard identifier/title entered in CALGreen, and where CALGreen refers to it.

Requirements in detail

What Chapter 6 actually contains (plain list)

  • A list of organizations (promulgating agencies) and the standards they publish. § 601.1 calls out that the chapter “lists the organizations and standards that are referenced in various sections of this document.”
  • The table rows show at least these columns: STANDARD ACRONYM or NUMBER, STANDARD NAME or TITLE, and REFERENCED SECTION (the CALGreen section(s) that cite the standard). The table header in the text shows those three columns.
  • Some referenced standards appear elsewhere in CALGreen (for example in the appendices or in Chapter 8 commissioning reference lists); some of those appendix reference lists are included only “as a convenience” and are not part of the mandatory code unless specifically adopted by a jurisdiction.

How to use the table — decision checklist (quick)

Decision / question What you do in Chapter 6 Code Reference
Do I need the exact standard CALGreen cites for a provision? Find the standard acronym/number or title in Chapter 6, then go to the REFERENCED SECTION column to see the CALGreen section(s) that rely on that standard. § 601.1
How are standards grouped? Look under the promulgating agency heading (tables are organized by agency acronym). Chapter 6 groups standards by the publishing organization (promulgating agency). § 601.1
Is a standard listed in an Appendix binding? No — some Appendix/Chapter 8 referenced standards are included “as a convenience” and are not part of the code unless adopted locally. Confirm adoption status with the authority having jurisdiction. Appendix/Chapter 8 notes
What if the table doesn't show edition/effective date? The Chapter 6 header in CALGreen shows the columns and agency grouping. If edition/effective date is not shown in the CALGreen entry, obtain the correct edition from the promulgating agency or ask your authority having jurisdiction — CALGreen’s Chapter 6 lists the identifier and where it’s referenced, but the file text does not guarantee every entry includes edition information. § 601.1 (table header)

Practical reading tips

  • Always note the REFERENCED SECTION column value and open that CALGreen section first — the code text there tells you how the standard is being used. Chapter 6 is a cross‑reference tool, not the primary regulatory language.
  • If a referenced standard is needed to satisfy a requirement in CALGreen, you must comply with the CALGreen provision that cites it (the standard is used to define methods, test procedures, or performance requirements where CALGreen references it). The table shows where to find those provisions.

Exceptions & special cases

  • Appendix/commissioning referenced standards may be provided for user convenience and are not automatically part of the mandatory code unless adopted by the local jurisdiction; verify adoptive status before relying on an appendix standard as a compliance path.
  • Some voluntary measures and appendices are intended for optional local adoption (CALGreen notes that voluntary measures “may be mandatory if adopted by a city, county, or city and county as specified in Section 101.7”). If you rely on a voluntary appendix, check whether your jurisdiction has adopted it.
  • The Chapter 6 table gives the cross‑reference but not always the administrative rule about how a standard applies (if CALGreen has a separate “application” clause elsewhere, that clause controls). The materials retrieved for § 601.1 do not include a standalone CALGreen phrase that tells you “the application of the referenced standards shall be as specified in …” (other California codes use that language with a section reference). If you need an application rule, confirm in the applicable CALGreen section or ask the authority having jurisdiction.

Common mistakes

  • Assuming every standard listed in an appendix or in Chapter 6 is automatically mandatory — some appendix lists are convenience documents and require local adoption to be enforceable.
  • Citing the wrong edition of a standard because Chapter 6 entry lacks the edition field — always confirm edition/effective date from the promulgating agency or the AHJ when the CALGreen table does not show it.
  • Treating Chapter 6 as the normative text for a requirement — Chapter 6 cross‑references standards; the actual legal requirement (and any exceptions) appear in the CALGreen section(s) that cite the standard. Start at the referenced CALGreen section, not only the Chapter 6 entry.

Worked example — lookup and use (concrete)

Scenario: Your project’s HVAC balancing work references an industry standard named “Total System Balance” that you’ve heard is required.

  1. Open CALGreen Chapter 6 and search the table for the standard (look up the promulgating agency or the title). The Chapter 6 table lists Total System Balance under the appropriate agency/entry and shows the CALGreen section(s) that reference it (for example, the table shows a “Total System Balance” entry with 5.410.4.3.1 and related cross references).
  2. Go to CALGreen § 5.410.4.3.1 (the referenced CALGreen provision). Read that section to see how CALGreen uses the standard — it will state whether the standard defines test method, acceptance criteria, or an installer responsibility. The Chapter 6 entry only told you where to look; the actual requirement is in § 5.410.4.3.1.
  3. Confirm the edition or effective date of “Total System Balance.” If Chapter 6 does not list the edition, obtain the edition from the promulgating agency or confirm with the building official (the Chapter 6 table provides the identifier and the referenced section but may not contain the edition field in every case).
  4. If the standard you found is listed in an appendix or in Chapter 8 commissioning reference lists that are “convenience” documents, verify whether your jurisdiction has adopted that appendix as mandatory before assuming it’s an enforceable compliance path.

Related provisions

  • § 601.1 — Chapter 6 general statement: lists organizations and standards; grouped by promulgating agency.
  • § 5.410.2 — Commissioning (referenced by Chapter 8 sample/commissioning materials). See Appendix/Chapter 8 cross‑references for commissioning reference lists.
  • Chapter 8 / Appendix — Compliance forms, worksheets and reference material; some reference lists here are provided “as a convenience” and may not be mandatory unless adopted locally.
  • § 101.7 — (See note in CALGreen about local adoption of voluntary measures and appendices — voluntary measures may become mandatory if adopted by a local jurisdiction.)

    Chapter 16 Stationary Power Plants. This chapter provides minimum requirements for stationary fuel cell power plants. A fuel cell is a device that produces electricity by a chemical reaction. Fuel cells have been used mostly for satellites. However, the costs of fuel cells have decreased to a point where they are now economically attainable. With the increase in electricity costs, fuel cells are being considered as an alternative for producing electricity.

    Chapter 17 Geothermal Energy Systems and Ambient Temperature Loops. Chapter 17 regulates the design, installation, construction, and location of geothermal energy systems and ambient temperature loops (ATLs). This chapter provides the minimum safety requirements for various types of geothermal systems, including building systems coupled with a ground-heat exchangers, submerged heat exchangers using water-based fluid as a heat transfer medium, and groundwater (well). For ease of use and clarification on the applicability of geothermal provisions, Chapter 17 is divided into five parts pertaining to general provisions for all types of geothermal systems, closed-loop systems, open-loop systems, direct-exchange (DX) systems, and ambient temperature loops. For district ambient temperature loops, including those utilizing multiple hybrid systems, Part I through Part V are applicable.

    In order to properly design a geothermal system, it is important to know the seasonal variation in the soil temperature, as well as the soil’s inherent capability to store and transmit heat, namely its heat capacity and thermal conductivity. In addition, a properly designed heat pump distribution system is essential for the distribution of geothermal energy.

    Materials for piping and tubing must meet the working temperature and pressure of the system. Furthermore, materials must be compatible with the transfer medium to prevent deformation, bursting, or any chemical action between the material and the transfer medium. Approved materials for indoor piping, fittings, and accessories that are a part of a groundwater system as well as the allowable joining methods for piping or tubing are provided for application and enforcement purposes.

    Chapter 18 Referenced Standards. Chapter 18 provides two comprehensive tables with referenced standards. The standards listed in Table 1801.1 are applied as indicated in the applicable reference section(s). A list of additional approved standards, publications, practices, and guides that are not referenced in specific sections appear in Table 1801.2.

    Referenced standards set forth specific details of accepted practices, materials specifications, or test methods in many specialized applications. Standards provide an efficient method of conveying complex information and specifications on the performance requirements for materials, products, systems, application, and installation. The manner and purpose for a standard’s use and, in turn, code compliance, must be definitive in all references to the standard. If the standard is intended to be a requirement for judging code compliance, the code must state its intent for use. The standard should adequately address a defined need and at the same time specify the minimum performance requirements, technical characteristics and methods of testing, and required test results.

    The referenced standards tables are organized in a manner that makes it easy to find specific standards in alphabetical order, and by acronym of the publishing agency of the standard.

    Systems that carry nonabrasive exhaust, such as smoke, moderate abrasives such as sawdust, and high abrasives such as manganese or acid vapors use product-conveying ducts. Part II provides the minimum fire safety requirements related to the design, installation, inspection, and maintenance of grease-type operations, such as cooking, for both fuel-gas and solid fuel. Cooking produces a significant amount of smoke, fumes, vapors, heat, and other pollutants. Therefore, acceptable kitchen ventilation is necessary to prevent fires from the build-up of grease and to provide the occupants protection from smoke, unpleasant odors, pollutants, and dangerous gases. There are two types of exhaust hoods (Type I and Type II) used in commercial kitchen applications.

    FORMAT OF THE UNIFORM MECHANICAL CODE

    Type I hoods are intended to be installed above equipment or appliances that generate grease or smoke. Type II hoods are intended to be installed above equipment or appliances that generate steam, vapor, heat, or odors and do not generate grease or smoke.

    Chapter 6 Duct Systems. Chapter 6 regulates requirements for ducts and plenums that are portions of a heating, cooling, ventilation, or exhaust system. This chapter contains material and installation requirements for metal, gypsum, factory-made, flexible, and plastic ducts. It also contains provisions for duct insulation, dampers, fire protection, and automatic shutoff for the building’s air distribution system. It is worth noting that exhaust ducts are regulated by Chapter 5, and combustion air ducts are regulated by Chapter 7.

    Chapter 7 Combustion Air. Chapter 7 regulates combustion air requirements for ventilation and dilution of flue gases for appliances installed in buildings. Fuel-gas appliances not regulated by chapter include direct vent appliances and Type I clothes dryers. Makeup air requirements for Type I clothes dryers are located in Chapter 5. Chapter 7 provides acceptable methods for supplying satisfactory combustion air to ensure proper combustion. Combustion air can be supplied by using indoor combustion air or by introducing the air from the outdoors.

    Combustion is the rapid oxidation of fuel to release energy. The oxygen required to release the energy from the fuel normally comes from the air. Incomplete combustion of fuel occurs when inadequate oxygen is provided to the appliance. Combustion is needed to provide ventilation cooling for the casing and internal controls. When a lack of oxygen occurs, some of the carbon is not oxidized, and carbon monoxide forms.

    Chapter 8 Chimneys and Vents. Chapter 8 regulates the installation, design, and construction of venting systems for fuel-burning appliances. The provisions addressed within this chapter follow procedures an installer would use to design or evaluate a venting system. Many requirements apply to the design and construction of venting systems, chimneys, installation of gas vents, and the sizing of venting system for a Category I appliance. Sizing venting systems require rigorous engineering calculations. However, the venting sizing requirements and sizing tables in this chapter already perform the calculations for the benefit of the end user.

    Combustion appliances produce products of incomplete combustion, including potentially harmful carbon monoxide (CO). It is desirable to vent these products to the outdoors. Although the gas is clean-burning fuel, the products of combustion must not be allowed to collect within a building.

    COMPLIANCE FORMS, WORKSHEETS AND REFERENCE MATERIAL

    PART 1 STANDARDS FOR COMPLIANCE WITH BUILDING COMMISSIONING

    Reference: Section 5.410.2, Commissioning.

    Introduction:

    The purpose of this code is to improve public health, safety and general welfare by enhancing the design and construction of buildings through the use of concepts that reduce negative and increase positive environmental impacts. Commissioning is a vital element in this effort.

    Definitions used in the CALGreen Cx Reference standard:

    Acronyms

    BOD Basis of Design

    Cx Commissioning

    FPT Functional Performance Test

    HVAC Heating, Ventilating and Air-Conditioning

    O&M Operations and Maintenance

    OPR Owner’s Project Requirements

    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

What if Chapter 6 lists a standard but no edition or date?

Confirm the correct edition with the promulgating agency or the authority having jurisdiction. The Chapter 6 table provides the identifier and cross‑reference but may not include full edition details in every entry.

Are standards in the appendices enforceable statewide?

Not automatically. CALGreen notes that some appendix referenced standards are included as a convenience and are not part of the code unless officially adopted by the local jurisdiction. Always check local adoption.

Do I ever need to read Chapter 6 instead of the cited section?

Use Chapter 6 to locate the standard and the CALGreen section(s) that rely on it; the substantive requirement is in the CALGreen section that cites the standard, so review that cited section next.

If a CALGreen section references a standard, must I obtain the standard document?

Yes — when a CALGreen provision delegates a method, test, or performance requirement to a standard, you need the standard text (and the correct edition) to perform or document compliance; Chapter 6 tells you which standard to obtain.

Where do I confirm whether a voluntary appendix measure was adopted locally?

Check your locality’s adoption ordinance or the adopting-agency matrix referenced in CALGreen (local resolutions or adoption tables indicate whether voluntary appendices were adopted). CALGreen notes voluntary measures may be adopted locally (see Section 101.7 context).
