The design guidance, identified as addendum 62o, was approved for publication at ASHRAE's 2002 Annual Meeting held in Honolulu, June 22-26. The addendum addresses the use of ventilation to control odors from tobacco smoke. It does not address health effects.

The addendum provides a method to allow designers to determine the additional ventilation over what would be provided in a similar non-smoking area, according to Andrew Persily, chair of the 62 committee.
