FOREWORD

ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2020 Addendum ax adds a reference to ANSI/ASHRAE Standard 62.1, Section 7, "Construction and System Start-Up," which includes several requirements that support good indoor air quality. To avoid duplication and confusion, it also deletes some requirements from Standard 189.1, Section 10, that are covered by the referenced section in Standard 62.1.

Standard 189.3, Section 10.2, "Compliance," notes "The construction and plans for operation shall comply with provisions of Standard 189.1, Section 10, except as specifically deleted, excepted, modified, or enhanced in accordance with Sections 10.3 through 10.5 of this standard." Addendum c to Standard 189.3-2021 provides for IAQ construction management and start-up by referencing ANSI/ASHRAE/ASHE Standard 170.

Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and strikethrough (for deletions) unless the instructions specifically mention some other means of indicating the changes.
