Dear all,

Can anyone suggest how to estimate the OA needed for a warehouse?

That warehouse is huge, air conditioned, with 12 ventilation windows covered by louvers, each louver is about 3 ft X 3 ft.

I would like to make it to be positive pressure, but how to estimate the fresh air rate?

10-20 people work inside, no diesel power truck.

Should I block most of the windows?

Real question is
1. if no modification of the ventilation windows (louvers), how much volume is needed?
2. Or any source for this system type estimation?

Very appreciate.
