A few years ago, Paul Gerner began to gather a group of architects in Las Vegas to ask them whatit would take to design a public school that used 50 percent less energy, costmuch less to build and obviously improved student learning. “I think half ofthem fell off their chairs,” Gerner says. Gerner manages school facilities （设施） for Clark County, Nevada, adistrict roughly the size of Massachusetts. By 2018, 143,000 additionalstudents will enter the already crowded public-education system. Gerner needs73 new schools to house them. Four architecture teams have nearly finisheddesigning primary school prototypes （样品） they plan toconstruct their schools starting in 2009. The district will then assess howwell the schools perform, and three winners will copy those designs in 50 to 70new buildings. Green schools are appearing all over, but in ClarkCounty, which stands out for its vastness, such aggressive targets aredifficult because design requirements like more natural light for students goagainst the realities of a desert climate. “One of the biggest challenges isgetting the right site orientation （朝向） ,” Mark McGinty,a director at SH Architecture, says. His firm recently completed a high schoolin Las Vegas.“You have the same building, same set of windows, but if its orientation isincorrect and it faces the sun, it will be really expensive to cool.” Surprisingly, the man responsible for one of the mostprogressive green-design competitions has doubts about ideas of eco-friendlybuildings. “I don’t believe in the new green religion,” Gerner says. “Some ofthe building technologies that you get are impractical. I’m interested in thosethat work.” But he wouldn’t mind if some green features inspire students. Hesays he hopes to set up green energy systems that allow them to learn about theprocess of harvesting wind and solar power. “You never know what’s going tostart the interest of a child to study math and science,” he says. 63.
