I like both ideas - would it be possible to combine them without living 
in something like the Pompidou Centre in Paris?

Another heat saving or cooling idea is heavy lined curtains.  In the 
winter, as soon as dusk starts, draw the curtains closed to retain the 
heat.  During the hot parts of summer, close the curtains and windows 
when they are subjected to direct sunlight so that the room doesn't 
become too hot.  I spent most of the past week away and closed all 
curtains and was greeted with a nice cool flat when I got home on Friday.
