Romania’s entry into Solar Decathlon Europe 2012 is called PRISPA (“porch”). The PRISPA team took a keep-it-simple approach to the design of the house, forgoing a lot of the cutting-edge technology favored by the other teams. Instead they adapted tried-and-true materials and systems, using them in innovative ways. As a result, PRISPA was the least-expensive house to build at SDE 2012, and is probably one of the most viable for production. Nevertheless, it still meets the goal of producing more energy than it consumes.
