     At Dallm/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim

immediately when it's sunny md brighten when a passing cloud blocks the sun.

     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.

     Many new materials and technology have been designed in the last 15 years. They now being used in a

wave of buildings designed to save as much energy as possible. They include old ideas, like"green roofs,"

where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new

ideas, like special coating for windows that lets light in, but keeps heat out.

     As technologies such as sensors become cheaper, their uses spread.

     The elevators (电梯) at Seven World Trade Center, which is under construction in New York, use a

system that groups people traveling to nearby floor into the same elevator, thus saving elevator stops.

People who work in the building will enter it by swiping (刷) ID cards that will tell the elevators their floor;

readouts will then tell them which elevator to use. The building also has windows with a coating that blocks

heal while letting in light.

     More new building materials and technology are in development. A Philadelphia building farm is now

working on"smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters (传感器)

the width of a human hair to move it. They are expected to change the face of the construction industry in

the next ten years or so.

B. Buildings Are Getting More Sunlight

C. Buildings Are Lacking in Much Energy

D. Buildings Are Using Cheaper Materials
