Active and passive venting of the roof

This passive-active venting system, along with decent bathroom and kitchen fans vented through the roof, should keep heat and moisture levels in the walls and plenum to a minimum.  

 This solar fan will be mounted on the roof, at the front.  It has a thermal switch attached, which will activate the fan at around 75 degrees F.  Notice that it is not "Made in the U.S.A." but rather, "Made in Texas."

This is one of the two passive vents we are installing--in the holes left behind by the roofer back in 10/2009.  They are in good spots on the roof already, thus no sense in fixing them just to put two more holes in the roof...
