The south face of a masonry foundation, painted black, sheathed in insulated glazing. Theirs trombe wall would be vented into the living space, the conditioned air returning to the lowest coldest point of the trombe foundation as it cooled via a return air duct.
Insulated, reversible shutters would be used to increase
solar gain during a winter day by opening and exposing their mirrored interior surface, improve thermal retention by closing during winter nights, and prevent
solar gain during cooling season by being flipped , mirrored side out and kept closed .
Plantings in front of the trombe would be deciduous, for naturally adjusting shade.
So is this a thing already? Or is it a stupid thing already, with known pitfalls ? Does it seem feasible?
