When I finally get around to building a pole building for aquaculture, I'm seriously considering having a south facing wall a trombe wall. That is, a block wall painted black with large glass windows about 4 inches out to heat the block wall to 150 degrees in the winter via sunlight. There are slots in the walls up high and low that passively circulate the warm air through the a higher slots due to the fact that warm air rises, and the cooler air in the building sinks and comes into the area of heating via the lower slots. In the warmer parts of the year the glass is shaded with economical shades that are made just for that purpose.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
