Solar Powered Attic Fans

The best attic ventilation for your Custom Home, I've found, are soffit vents with off ridge vents. Cool air is drawn into the soffit vents on the low side, travels upward along the inside of the roof sheathing and exits through the off ridge vents near the peak of the roof. This type of attic ventilation follows natural forces and operates for free. 

Every few years they come out with some new type of vent system for your Central Florida home. Gable vents, turbans, whole house vents, power vents as well as solar vents. None work as effectively as the system outlined above. 

One other aspect of ventilation, there can be too much of a good thing. Create too much suction and it will suck air conditioning right out of the living space and cost you money. 

Below is an article that adds more background information.
