NASA's Sustainability Building, the government's greenest building, opening in California this year

You may or may not have heard about NASA's project to build the most sustainable federal building in Moffett, California. The project began about two years ago, and will supposedly be finished this May. The experimental, earthly 'space station' cost $20.6 million to build, and includes 50,000 square feet of work space on two floors. The building also includes radiant ceiling panels, heating panels on walls, and radiant concrete flooring. When completed, the Sustainability Base will use 90 percent less potable water than a regular office building of the same size, and it will be able to create 22 percent more energy.
