Seems to me the solution is better planning/thinking/building...incorporate both passive cooling (clerestory windows, basements, wind towers) and passive heating (appropriately placed, double hung windows that can open top down or bottom up, insulation, thermal building materials, overhangs, ceiling fans...) is the truly whole environmentally sound concept that is ideal.

Thinking about the idea of a wind tower that funnels hot air up and out, I question if this could this be done mechanically. My thought is to take the dead space above the closet in the vaulted ceiling area and install air vents on three sides with a powerful heat extraction fan that would exhaust either into the attic or directly outside (this would be the non windy side of the house). The pull of the high, heated air being extracted "should" have a secondary effect of pulling in the cooler, lower air/prevailing winds from outside, through the open windows. In winter, this fan could easily be sealed off from the inside, within the closet, to prevent heat loss when it is cold out.
