[Greenbuilding] Solution sought for heat rising problem

[John Salmen]

The loft /bedroom probably has a 2x4 wall to the peak - the 14.5" space in
the frame cavity can be used as a plenum or duct to draw air down - intake
grills on both the bedroom and living side at the peak and a supply fan at
the base will draw air down to at least the main floor ceiling ht (some
circulation and bdrm exhaust). Or simply add a framed box/duct - floor to
ceiling that looks like a wall bumped out.

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.

How to bring the rising warm air down to the occupied space below?

 

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.

Ideas/suggestions/solutions for a good way to distribute the warm air would
be appreciated.  When winter hits this part of the world, the bedroom space
will be overly warm while those sitting below will be uncomfortably cold.

thanks, Sacie
