FOREWORD
Residential occupancies that are four (4) stories or more were removed from Standard 62.1 with the 2016 version. Some spaces within these buildings, such as common corridors, lobbies, etc., may still fall under the scope of Standard 62.1. This addendum removes some items related to nontransient occupancies that are now under the scope of ANSI/ASHRAE Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Residential Buildings.
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.
