This week, the American of Institute of Architects and its Committee on the Environment announced the 10 best green buildings completed in the past year. It's filled with all manner of green technologies--from passive heating and cooling using heat pumps, to man-made wetlands, to reclaimed materials. Here's a slideshow of all ten.

355 11th Street by Aidlin Darling Design. It's hard to tell, but the building was once a 100-year-old, derelict industrial warehouse. But the site happened to sit on the National Register of Historical Places--meaning the architects had to replicate the area of metal cladding and windows on the former building, in new materials.

An interior view. The zinc cladding outside the building lifts off the facade, creating shade an a "breathable envelope" of air that flows over the building, cooling it.

The King Abdullah University of Science and Technology by HOK. Try not to chuckle at the irony: The project is Saudia Arabia's first LEED certified project, and the world's biggest LEED platinum building; the school is dedicated to the study of energy and the environment. Just keep the petro-dollars flowing!

The Special No. 9 House in New Orleans, LA, by KieranTimberlake. The house was one of the first completed by Brad Pitt's Make It Right foundation, which is building 150 homes in the Ninth Ward, which was flooded and leveled by Hurricane Katrina. (For our previous coverage of the Make it Right designs, click here.)

The house was custom-built for a single family, but the plans are being readied for pre-fab, mass-production.

The City of Watsonville Water Resources Center by WRNS Studio.

Twelve|West in Portland, OR, by Zimmer Gunsul Frasca Architects. The mixed-used building is expected to earn a LEED platinum, with energy savings of 45% over a comparably sized building.

The interior is covered in wood that's either been reclaimed, or sustainably harvested.

The Omega Center for Sustainable Living (OCSL) by BNIM Architects--one of the greenest buildings in North America. ( Click here for our previous coverage.)

The building is net-zero: All of the energy comes from sources on site, mostly from solar panels.

An "eco machine," comprising an man-made wetland, cleans the building's waste water and returns it to the land.

Kroon Hall, which now houses Yale's school of forestry and environmental science, designed by Hopkins Architects and Centerbrook Architects. The building successfully blends a huge array of solar panels into Yale's famous gothic architecture. (For our previous write-up of the building, click here.)

Manitoba Hydro Place by Kuwabara Payne McKenna Blumberg Architects. The 22-story office tower houses the primary energy utility of Manitoba.The

The energy demands are managed by computers that control the light exposures, as well as numerous passive heating and cooling mechanisms.

Manassas Park Elementary School by VMDO Architects.

...as do the classrooms.
