RE: air change
Peak of the building to floor and all walls sides?
Height x Width x depth of length? in cubic ft or meters?
Or just cooling air changes of the top 8 ft high or less for open - top offices and manufacturing and retail, etc, not trying to cool all of the air space to the ceiling...?

RE: air change
just ventilating won't cool it much unless you have much internal heat geenration. If it is 100°f outside, bringing in air won't make it colder than 100°F

RE: air change
Air changes per hour (ACH) = (cfm * 60) / room volume.
Room volume is area times ceiling height.
Airflow is in cubic feet per minute times 60 minutes per hour. Divided by the room volume in cubic feet. It's a unitless number.
For cfm, you use the higher of supply or exhaust.

Not rocket science
RE: air change
anyway, would be good what the question is for, a design?

RE: air change
The phrase "cooling air chance" carries little sense by itself but if we assume that question is posted by person not familiar with basice, I would assume that Mr. needs to calculate supply air flow needed for cooling the space...
chas, your intentions are undoubtedly good, but giving hand to someone who possibly doesn't know where he is going toward is unlikely to give satisfactory results, sometimes it's more pressing to determine whether he is going to abyss.
