If you are referring to powered attic ventilators (mounted in your roof), don't bother. This has been researched by the energy labs. Heat is primarily transferred from the hot underside of your roof sheathing to everything in your attic through radiative transfer. An attic ventilator will not address the radiative transfer issue. Powered ventilators may also suck conditioned air from your home if the ceiling penetrations are not sealed well. Save your money.

My insurance company has suggested that I replace my large power vent with two hip roof side ridge vents. He said it would be more aesthetic, lower my electric bill and actually function better. I have found articles on the web that seem to support this. Has anyone done this?
