Extreme climate conditions may require power assist to optimize animal comfort.
Dual Ventilation Systems
Extreme climate conditions such as northern winters and southern summers may require power assist to maximize or minimize air flow to optimize animal comfort. Sun-North incorporates power sidewall fans that engage before the natural ventilation sidewall panels and ridge systems are implemented.
Typically, power assist would be assigned for a minimum of 20% of the needed ventilation. This allows the producer to utilize natural ventilation 80% of the time, save on energy costs and know a ventilation system will still be fully operational in the event of a power failure greatly reducing the risk of animal suffocation in circumstances of extreme heat.
