July 9, 2003—An addendum that changes the ventilation requirements in ASHRAE Standard 62 to apply only to nonsmoking spaces while still providing design guidance for controlling odor in indoor spaces where smoking occurs is now available.
ANSI/ASHRAE Addendum 62 to ANSI/ASHRAE Standard 62-2001, Ventilation for Acceptable Indoor Air Quality, is available for free through the association’s Web site.
The addendum includes the deletion of smoking lounges from a table on outdoor air requirements for ventilation. An informative appendix (meaning it is not required for compliance for the standard) that provides a method to allow designers to determine the additional ventilation over what would be provided in a similar nonsmoking area also is included. However, this additional ventilation is for the purpose of odor control only.
