Site Planning and Design (Division A6.1)

Division A6.1 (Appendix A6) directs site development and planning measures (see Section A6.106 and § A6.106.9) to reduce environmental impacts and improve building performance.

Last reviewed: July 6, 2026

Overview

Division A6.1 of the CALGreen Appendix A6 collects site-planning and site-development guidance tailored for health facilities, focusing on how siting, orientation and landscape decisions reduce environmental impacts and improve occupant comfort and safety. The Division identifies site-development provisions (Section A6.106) and specific measures such as building orientation (see § A6.106.9) that guide placement and shading to reduce thermal loss and manage solar exposure.

Although framed in the Appendix for state health-care occupancies, the Division aligns with the Chapter 5 planning-and-design topics used across CALGreen — stormwater control, bicycle and EV parking, shade/landscape, heat-island reduction and permeable surfaces — and cross‑references the Chapter 5 site development sections and voluntary planning electives. These cross-references help designers apply consistent site best practices (stormwater, shading, low‑impact development, EV readiness, bicycle parking, etc.).

Practically, Division A6.1 is used during early design and site feasibility: orient buildings to reduce energy use and wind exposure, locate landscape and shading to protect envelopes and manage stormwater, and plan parking and circulation to support active transportation and future electrification — all documented in the Site Development section and related CALGreen tables and appendices.

    CALGreen VERIFICATION GUIDELINES

    TIER 2 CHECKLIST

    Application: This checklist shall be used for nonresidential projects that meet the following: new construction, or building additions of 1,000 square feet or greater, or building alterations with a permit valuation of $200,000 or more pursuant to Section 301.3, AND are adopting Tier 2 voluntary measures.

    Note: All applicable mandatory requirements in Chapter 5 shall be met prior to applying Tier 2 voluntary measures.

    Instructions:

    Comply with all Tier 2 prerequisite measures from the various categories shown on the table below.

    Add a “ Y ” to all mandatory and Tier 2 prerequisite measures in the appropriate columns.

    Select the required number of additional electives from those categories shown on the table below and add a “ Y ” on the selected elective and add an “ N ” on the rest.

    Count the total number of Tier 2 prerequisite measures plus the additional electives and write down the total number at the end of the checklist. Determine if the required number of Tier 2 measures have been selected to achieve Tier 2 compliance.

    Y = Yes (section has been selected and/or included) N = No (section has not been selected and/or included) O = Other (provide explanation)

    [N] = New construction pursuant to Section 301.3

    [A] = Additions and/or Alterations pursuant to Section 301.3

Frequently asked questions

What specific section covers site development and building orientation in A6.1?

Site development is addressed in Section A6.106; building orientation is specifically required and described in § A6.106.9.

How does Division A6.1 relate to the mandatory Chapter 5 planning provisions?

Division A6.1 (Appendix A6) parallels and cross-references Chapter 5 planning-and-design provisions (e.g., stormwater, bicycle/EV parking, shade and heat‑island measures) so health‑facility projects can apply the same site best practices found in Chapter 5.

When should designers consult A6.1 during a project?

Consult Division A6.1 during site selection and schematic design to set building orientation, landscape/ shading strategies, stormwater controls and parking/electrification planning — decisions that influence energy performance, water management and occupant health.
