Energy Efficiency & Electives (Division A5.2)

Division A5.2 compiles voluntary energy-performance options and selectable elective measures (lighting, HVAC controls, renewables, etc.) that projects can use to exceed baseline energy requirements or meet CALGreen Tier criteria.

Last reviewed: July 6, 2026

Overview

Division A5.2 of Appendix A5 collects voluntary energy-efficiency measures and elective options for nonresidential projects — from targeted prescriptive items (outdoor lighting, daylighting power adjustments, service water heating for restaurants, warehouse dock seals, exhaust-air heat recovery) to program-level energy budgets and on-site renewables and green power options. Key provisions include the energy-performance electives in §A5.203.1.1 and the energy-budget options in §A5.203.1.2, which set alternatives to Part 6 compliance for voluntary tiers and enhanced performance.

The division also lists specific elective measures — for example, on-site renewable energy (§A5.211.1), green power (§A5.211.3), controls that reduce energy (§A5.212.1.4), and elevator/escalator energy measures — that can be selected to meet Tier 1 and Tier 2 voluntary requirements. Project teams use these electives to achieve enhanced CALGreen tier status or to exceed mandatory energy standards while documenting chosen measures for verification.

    A5 NONRESIDENTIAL VOLUNTARY MEASURES

    DIVISION A5.4 – MATERIAL CONSERVATION AND RESOURCE EFFICIENCY

    SECTION A5.401—GENERAL

    A5.401.1 Scope. The provisions of this chapter specify the requirements of achieving enhanced compliance with material conservation, resource efficiency, and greenhouse gas (GHG) emissions reduction through reuse of existing building stock and materials; use of recycled, regional, rapidly renewable and certified wood materials; and employment of techniques to reduce pollution through recycling of materials.

    SECTION A5.402—DEFINITIONS

    A5.402.1 Definitions. The following terms are defined in Chapter 2.

    BUILDING COMMISSIONING.

    BUY CLEAN CALIFORNIA ACT (BCCA).

    CRADLE-TO-GRAVE.

    EMBODIED ENERGY.

    EUTROPHICATION.

    LIFE CYCLE ASSESSMENT (LCA).

    LIFE CYCLE INVENTORY (LCI).

    OVE.

    POSTCONSUMER CONTENT.

    PRECONSUMER (or POSTINDUSTRIAL) CONTENT.

    RECYCLED CONTENT.

    RECYCLED CONTENT VALUE (RCV).

    REFERENCE STUDY PERIOD.

    TYPE III ENVIRONMENTAL PRODUCT DECLARATION (EPD).

    FACTORY-SPECIFIC EPD.

    INDUSTRY-WIDE EPD (IW-EPD).

    PRODUCT-SPECIFIC EPD.

    SECTION A5.403—FOUNDATION SYSTEMS (RESERVED)

    SECTION A5.404—EFFICIENT FRAMING TECHNIQUES

    A5.404.1 Wood framing. Employ advanced wood framing techniques or OVE, as recommended by the US Department of Energy’s Office of Building Technology, State and Community Programs and as permitted by the enforcing agency.

    A5.404.1.1 Structural or fire-resistance integrity. The OVE selected shall not conflict with structural framing methods or firerated assemblies required by the California Building Code.

    A5.404.1.2 Framing specifications. Advanced framing techniques include the following:

    1. Building design using 2-foot modules;
    2. Spacing wall studs up to 24 inches on center;
    3. Spacing floor and roof framing members up to 24 inches on center;
    4. Using 2-stud corner framing and drywall clips or scrap lumber for drywall backing;
    5. Eliminating solid headers in non-load-bearing walls;
    6. Using in-line framing, aligning floor, wall and roof framing members vertically for direct transfer of loads; and
    7. Using single lumber headers and top plates where appropriate.

    Note: Additional information can be obtained from the US DOE Energy Efficiency and Renewable Energy (EERE) website.

    SECTION A5.405—MATERIAL SOURCES

Frequently asked questions

What does “elective” mean in Division A5.2?

Electives are optional, verifiable measures a project may select from Division A5.2 to gain voluntary CALGreen credit or to satisfy the additional requirements for Tier 1 or Tier 2. Examples and section references are provided so teams can document choices such as outdoor lighting reductions, daylighting power adjustments, or on-site renewable energy.

How does A5.2 interact with the California Energy Code (Part 6)?

Division A5.2 offers voluntary paths that either reduce allowances in Part 6 (energy-budget options) or add prescriptive/technology electives that can exceed baseline Part 6 performance. See §A5.203.1.1 (outdoor lighting and other prescriptive measures) and §A5.203.1.2 (energy-budget percent targets) for the primary interactions.

Which A5.2 sections are most commonly used for Tier 1/2 compliance?

Common choices referenced in the voluntary-tier checklists include §A5.203.1.1 (outdoor lighting and other prescriptive energy measures), §A5.203.1.2 (energy budget targets for Tier performance), and electives like §A5.211.1 (on‑site renewable energy) and §A5.212.1.4 (energy‑reducing controls). These are cited in the Tier checklists in Appendix A5.
