    How many changues of air in a smoking area?

    Hi to you all, currently my brother and a friends star the remodelign of a place to be a bar.

    Place will be ready for 100 to 250 people. In two main zones ( dont divided)
    in to areas similar, in this dimenensions.

    Length :12m
    Heigth: 2.7m
    width: 8m

    The manuals, says around 5 to 7 changues per hour, yet myself dont smoke and I want to make the place as smoke free... I went to an approach of 10 changes and went to distribute the extraction on 8 intakes.

    Is this will be sufficient?
    There is any rule of thumb for something like this?

    Thanks a lot.
    -Alex

    I don't know of any regs on this but there probably is. I have done air balance in this type of facility and the main thing you need to make sure of is that the smoking area is negative with respect to non-smoking.

    It depends on the level of smoke inside the room............maximum occupancy at a time...........basis which we can guide on air changes per hour.

    How about demand ventilation based on CO2 levels? I am making a big gamble in my facility that this will work to keep the air fresh and also control energy costs as population changes. Should have new system up in a month or so.

    Wouldn't be a problem in California. Not allowed to smoke in any work or public building.

    It will depend on how many people are smoking at once and the square footage and ventilation. You can add commercial stand alone air filtration sometimes called Smoke Eaters units to help with the load.
