One of the first questions a broiler producer has when considering building a new tunnel-ventilated house or updating an older house is, "How many fans will I have to buy?" Most often the answer is given in terms of house length. A 400' house requires a minimum of seven 48" fans, and a 500' house needs eight. Though this method of fan selection works out fine most of the time, it is not foolproof and in some cases can lead to hot birds and high electricity bills.
