We are designing an unconditioned “party barn” in Central Texas for occasional gatherings for groups of various sizes. The barn has about a 1,400 sf footprint — 1,400 sf at the ground floor then there is a loft that is about 200 sf. We have Big Ass Fans for air movement but would like to add an attic fan to exhaust the warm air that will build up in the loft/attic space. How do we calculate the amount of CFM that the fan should be moving?
