   A wall of windows at a University of Pennsylvania engineering budding has built-in blinds (百页窗) controlled by a computer program that follows the sun's path.

   Buildings are getting smarter -- and the next generation of building materials

expected to do even more.

   Windows could catch the sun's energy to heat water. Sensors that measure the carbon

dioxide breathed out by people in a mom could determine whether the air conditioning needs to be turned up.
