Advice needed for air conditioning a Factory (PLEASE HELP!!)

HI Everyone,
I am writing to ask if anyone could give me a case study or advice on cooling an Factory. This factory manufactures drills and tools.
There are several doors (3 12'x12', 4 3'x7')that remain open all day also. How do you obtain a correct load when these doors are open?
I am a little out of my league on this project and would love to receive any advice possible.
Thanks...

 

HI again,
Would spot cooling (where metal presses are etc.) work along with air curtains at the doors???

With large, open doors, you're fighting a difficult battle. The most important advice I can give for this application is to supply significantly more air than you exhaust (to the entire factory) so that the building is positive. You would still be in jeopardy during windy conditions, but this would be a good start. With a factory, there is usually tons of localized exhaust for the processes which makes a one-size-fits-all answer impossible.
