E Cigarettes

well...I think it is not the same as "tobacco smoke." I am not aware of this being covered in the scope of the prerequisite and we have not had any review comments asking about this but maybe if you were working on a bar or restaurant you might want to address this. For the building management's benefit (after the building is occupied) you may want to prohibit these....since some people confuse them for traditional tobacco cigarettes. My friend at a bar was told he couldn't use his e-cigarette because the owner said others take this as a cue that smoking is allowed and light up their tobacco cigarettes. The e-cigarette "juice" sometimes (not always) has nicotine. It might be good due-dilligence to see if this is harmful to people when exhaled. I don't know off the top of my head. If it is then it would be advisable to prohibit its use in a certified "green" building!

I just spoke with a USGBC / GBCI affiliate on this topic, and here is the response: The prerequisite does not apply to e-cigarettes and only applies to tobacco smoke. It may still be beneficial for the building/management to discourage people from using e-cigarettes within 25 feet of building entries, since others may see them and may think that regular smoking is allowed within 25 feet of the building.
