For instance, there was a seminar titled "Standard 62's Comfort-Only Approach to Smoking Spaces" at the 2004 Winter Meeting of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). The standard addresses comfort considerations in smoking spaces, but not health. Does that do anybody any good?
The real issue seemed to be whether or not you can protect yourself if the building owner decides to offer a smoking environment.
