Water Efficiency & Material Conservation (Divisions A5.3–A5.4)

Divisions A5.3–A5.4 of CALGreen present voluntary nonresidential measures to cut potable water use and the environmental impacts of building materials through prescriptive limits, reuse/recycling, LCA, and waste‑reduction strategies.

Last reviewed: July 6, 2026

Overview

Appendix A5 of CALGreen collects voluntary nonresidential measures; Divisions A5.3 and A5.4 focus respectively on reducing potable water use, encouraging onsite water reuse, and improving material sourcing, reuse, and waste handling to lower embodied impacts and construction waste. A5.3 includes prescriptive fixture and system limits and water‑reuse provisions (for example, fixture flow and flush limits at § A5.303.3.1 and shower flow limits at § A5.303.3.3.1) as well as graywater and nonpotable reuse guidance in § A5.304 and § A5.305 .

Division A5.4 covers material conservation and resource efficiency: general scope and definitions are in § A5.401, with elective and mandatory measures addressing recycled content, certified/rapidly renewable/reused materials, concrete/cement substitutions, life‑cycle assessment (whole‑building LCA) and construction waste management (see § 5.405, § 5.408 and § 5.409 for recycled content, CWM and LCA requirements) .

Although Appendix A5 is titled “Voluntary Measures,” many of its items are structured so projects can use them to meet CALGreen Tier prerequisites — e.g., Tier 1/2 selection and prerequisites reference specific A5.3 and A5.4 measures when pursuing voluntary tier certification .

    A5 NONRESIDENTIAL VOLUNTARY MEASURES

Frequently asked questions

Are Divisions A5.3–A5.4 mandatory for all projects?

No — Appendix A5 contains voluntary nonresidential measures. However, several A5 provisions are used as prerequisites or electives for CALGreen Tier 1 and Tier 2 compliance, so they become binding when a project pursues a tier path or when a local jurisdiction adopts specific A5 sections .

Where do I find the fixture limits and water‑reuse rules?

Fixture and flow limits (toilets, urinals, showerheads, etc.) are published in Division A5.3 (see § A5.303.3.1 and § A5.303.3.3.1). Graywater systems for subsurface irrigation and nonpotable water system requirements are in § A5.304 and § A5.305 and reference the California Plumbing Code for implementation details .

How does A5.4 address embodied carbon and waste?

A5.4 provides multiple paths: recycled content and product sourcing requirements, electives for bio‑based/rapidly renewable/reused materials, concrete and cement options, whole‑building life‑cycle assessment (LCA) provisions, and construction waste management (including high diversion targets and documentation in § 5.408 and LCA rules in § 5.409) to reduce embodied impacts and improve material stewardship .
