Commissioning requirements, OPR, plans, reports and sample forms

This page summarizes CALGreen commissioning requirements (OPR, BOD, Cx plan, functional testing, training, report) and points to the code sections and sample forms you’ll use.

Last reviewed: July 6, 2026

Overview

This part of CALGreen sets mandatory commissioning deliverables and a quality‑assurance process that starts in design and continues through occupancy. Key required documents and activities include the Owner’s Project Requirements (OPR), Basis of Design (BOD), commissioning measures shown in the construction documents, a project commissioning plan, functional performance testing, training and systems manuals, and a final commissioning report under Section 5.410.2 of the code §5.410.2 . The appendix guidance (A6.204.4) repeats and expands these elements for prescriptive projects and provides additional forms and checklists §A6.204.4 .

Commissioning matters because it verifies that systems — HVAC, lighting and daylighting controls, domestic hot water, renewables and building envelope among others — are installed and operate to meet the owner’s stated performance goals and the contract documents; it also documents training and operations information required for long‑term performance and code enforcement . Enforcement and plan‑check may be satisfied by submitting the commissioning plan, commissioning specifications, or the completed commissioning report (or an owner attestation), per the compliance guidance .

For quick navigation, the code lays out the specific sections you’ll use most: §5.410.2.1 Owner’s Project Requirements (OPR); §5.410.2.2 Basis of Design (BOD); §5.410.2.3 Commissioning plan; §5.410.2.4 Functional performance testing; §5.410.2.5 Documentation and training; and §5.410.2.6 Commissioning report — plus the sample forms and templates included in the CALGreen compliance‑forms part and Appendix (sample OPR, commissioning plan checklists, FPT forms and a commissioning report template) §5.410.2 and Part 2, Compliance Forms .

    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.

    Reference: 5 Functional performance testing

    CALGreen Section 5.410.2.4, Functional performance testing.

    5.1 Intent:

    Develop and implement the functional performance tests to document, as set forth in the commissioning plan, that all components, equipment, systems and system-to-system interfaces were installed as specified, and operate according to the Owner’s Project Requirements, Basis of Design, and plans and specifications.

    The following systems to be functionally tested are listed in the Basis of Design (Section 5.410.2.2 of the code):

    1. Renewable energy systems

    2. Landscape irrigation systems

    3. Water reuse systems

    5.2 Compliance Method:

    Compliance is demonstrated by developing and implementing test procedures for each piece of commissioned equipment and interfaces between equipment and systems according to the building-specific commissioning plan. Tests should include verification of proper operation of all equipment features, each part of the sequence of operation, overrides, lockouts, safeties, alarms, occupied and unoccupied modes, loss of normal power, exercising a shutdown, startup, low load through full load (as much as is possible) and back, staging and standby functions, scheduling, energy efficiency strategies and loop tuning.

Frequently asked questions

Who prepares the OPR and when must it be completed?

The OPR is prepared by the owner or the owner’s representative and must be documented before the design phase begins (see §5.410.2.1) §5.410.2.1 .

What must a commissioning plan include?

A project commissioning plan must be completed prior to permit issuance and include general project information, commissioning goals, systems to be commissioned, test plans with measurable acceptance criteria, commissioning team contacts, and schedules/responsibilities (see §5.410.2.3) §5.410.2.3 .

Are there sample forms and a required commissioning report format?

Yes — CALGreen provides sample compliance forms and templates (OPR checklists, commissioning plan checklists, Functional Performance Test forms, executed installation checklists and a Commissioning Report template) in the compliance‑forms section and appendix; the commissioning report must summarize results, deficiencies and include attachments like the OPR, BOD, executed checklists and FPT forms (§5.410.2.6) .
