Can you elaborate?  There's a large porch on the south side of the  
small farmhouse I recently bought.  Currently it's poorly designed  
and sealed, but still heats up very nicely when the sun is out.   
It'll be next summer before I can think about rebuilding it, but I'm  
collecting information and ideas on it now.  I'd like to open it up  
more and screen the whole thing, and have glass or plexi or whatever  
panels to close it in during the winter.
