If you want to use gable vents, you need wind or power fans otherwise the air don`t flow !! It also creats a horizontal vortex that mixes the air rather than move it !!
The installation of ridge vents combined with prop vents and soffit vents allows the rising of heat to drive, the soffit vents will intake and the prop vents on the rafters, allows your option to put a finished cieling for your loft room !! Wind is not an issue !!
If you have small crawl space,...same applies without the finished room !!
Ridge venting creats a vertical vortex, without wind, still moves air.
Consider: When the fire dept. goes to your house the first thing on their mind is occupants, then heat consentration in the attic along the ridge peak. that`s where they make the vent holes.
The New England Shakers, useually built Colonial style homes with the stairs in the center of the house from the basement to the attic. A coopular box vent was put on the roof atop the stairwell. (size depended on size of home or numbers of coopulars)
A oil powered chandelare was put atop the stairwell. The windows on the second and or third floor were closed. Only the windows on the first floor were left open a few inches. When the lanterns were lit in Summer, the heat rose up threw the coopular, drawing the air in the first floor windows. The size of the flame on the candles dictated the speed of the draft created by the chimney effect. This draft can be measured by a wind speed indecator. Sometimes enough to put out the candles !!
Just some quick input,....when I have time I`ll get more detailed for ya !!
