Earlier this month, we previewed each of 20 solar-powered homes competing in the Solar Decathlon in Washington, D.C. Over the next few weeks, we’ll try to delve into more detail to uncover innovation at its best. This house, the Silo House, was designed and built by over 150 students and faculty at Cornell University. It features three, 16-foot diameter silos that hold the kitchen, bedroom, and living room. The Silo House is grid-tied and powered by 40, 200-watt photovoltaic panels, a solar thermal system, and a building integrated solar thermal system. The Silo House currently leads the competition … will they be the team to take first place?
Yesterday, Dow Chemical Company (NYSE: DOW) unveiled its new line of DOW POWERHOUSE Solar Shingle. The Solar Shingle was designed to be integrated into rooftops with standard asphalt shingle materials. Dow expects the shingle systems to be available in limited quantities by mid-2010 and more widely available in 2011. And although the company says the system will provide a low-cost solar option for homeowners, we have not received any specific pricing details at this time (see below).
Green building certification is an interesting phenomenon. It’s meant to convey a message about the building’s level of “green” or “sustainability,” but the message is only as strong as the system that creates it. If you push beyond that message, you might ask: how many of these certified buildings are, say, positive energy? That’s the goal of Elithis Tower recently opened in Dijon, France. It has 1,600 sensors that examine energy and emissions. This information is then displayed on a special public sign in full transparency for everyone to see. The sign is both dynamic and clear.
