Concerning eco-freaks vs. space, you may find it interesting to
look at  http://www.islandone.org/LEOBiblio/SPBI100.HTM 
The author of that pages have had a rough time trying to

You think of surface structures only? Because for space-filling 
structures dividing space into habitable rooms, squares may be better...
Concerning cooling problems, see the water-cooled window concept at
