[Greenbuilding] Solution sought for heat rising problem

[Beatrice Dohrn]

A thought:  If a fan can push hot air down in the big open space (not too efficient -- right)  shouldn't it work to have a large "tube" of some sort that had a fan to make sure the flow was from up to down?  Seems to me that the rising hot air wants to keep moving, and if a fan would make air in the tube (I see one of those industrial rigid ducty-things... large diameter to allow for a good fan) move from high to low,  you'd get a flow going....  How you keep it quiet... or looking as they might want is another matter altogether.

>All, currently in Vermont; staying in a lovely house with a big  30'x30', tall 25'+ living room converted from a barn.  In addition to a radiant heated concrete floor, a new pellet stove that blows heat into the space has recently been installed.  About a third of the room is divided by a loft space that forms an extension to the larger room underneath and a bed room above.  The very high ceiling for the entire space is contiguous.

>The space is well insulated but at the same time it has many windows, at least ten.  It would not be practical nor would it look good to install a beam across the space from which a fan could be hung.  I don't think one can hang a large fan on what would have to be at least a 15 foot single pole.
