Building Pressuration

[david585]

I am attempting to pressurize a building. Can anyone tell me how to determine the cfm needed to keep the space at a pre-determined pressure? I posted this same request a couple of years ago and was directed to

thread403-43928

But when I go to this thread it says it is closed. Is there anyway I can access this thread?

You should be able to read the entire thread and ask any questions you may have in your current thread.

It would be needful to determine all the openings in the building which allow air to exit, find the amount of air that would flow out of each opening at the design pressure, and add more air to the total as a safety allowance.

Hi,
If this an occupied building, then there are codes you have to watch for. spcially, for fire and smoke systems. A pressurized building may not let the exit doors to open in case of fire. Check with the Architect also.

Finally, the internal presure amounts are ususally 0.1 to 0.2 in. water column I am not sure, let see what others input to this topic.
