USGBC/ GBCI Alt Path for Environmental Tobacco Smoke

Lucy, have you looked at Option 2, Case 1? (See more information in the tabs above.)

I have currently the exact same problem as Lucy, project is located inside an office building in Mexico City, smoking is prohibited on the inside, but there isn't any regulation on the outside that prohibits smoking within 25' from entrances, and tenants have no power over the entire building policy. I have looked at option 2, case 1, but I don't finish to get it, could an alternative be to prove that no ETS can migrate from terraces (where smoking is allowed) to inside the building through natural ventilation?

I doubt that smoke does not migrate inside from terraces, and it would be very difficult to prove that it does. In any case, I don't think that LEED would be flexible on that requirement.

Lucy, I would like to know what happened in the end with your project. Our prerequisite compliance is currently pending and we are having trouble on documenting for the final review. Which path did you follow?
