There's one thing that Virginia Tech is especially known for, and that's the great fall foliage... no, seriously, it's the architecture and engineering programs. Tech has some world-class chops when it comes to building things -- houses and stuff. So it's no surprise that its Solar Decathlon entry is a world-class PR production for the University. Year after year, Lumenhause gets praises and props the world over for its inspiring design and technology. Magazines, TV, social networks.... you name it, it's tweeted, liked and blogged (ehem).
