Solar Decathlon: Pittsburgh's Synergy House
Pittsburgh's entry into the Solar Decathlon 2005 was exercise in angles, with its north and south walls tilting 12 degrees to the south. To let in natural light and winter sun, the south wall enclosing the "great room" living and office space is all glass, with manually operated shades. The concrete floor of the great room stores heat from both sun and in-floor radiant heat pipes in the winter and keeps cool in the summer. The Pittsburgh Decathlon Team called itself Synergy, because it was a joint effort of Carnegie Mellon, the University of Pittsburgh, and The Art Institute of Pittsburgh.
