Hobbit House in Wales Made from Trees

http://www.solaripedia.com/13/175/low_impact_woodland_home_%28wales%29.htmlThe low impact woodland home built by Simon Dale in Wales conjures images of Hobbits baking bread in tiny hand-made ovens and friendly gatherings among the denizens of Middle Earth. But this extremely natural home also utilizes solar PV technology to bring lighting, music, refrigeration and computing power into this outgrowth of the forest. Dale and his father-in-law spent about four months and $6,000 building the home in 2008. Besides the PVs, they made it as sustainable as possible with oak, straw bale walls, roof and floor, a vegetated roof, and lime plaster on the walls.

Bank of America Towers over Manhattan

http://www.solaripedia.com/13/173/1725/bank_of_america_tower_ice_tanks.htmlThis ultra-green skyscraper uses power to turn water into ice to chill the building. The cooling system produces and stores ice during off-peak hours in large tanks in the subbasement. Then the ice is used to help cool the building during peak load, essentially operating like giant ice batteries. Ice batteries have been used since absorption chillers first made ice commercially 150 years ago, before the electric light bulb was invented.
