During the recent $550 million upgrade of the Empire State Building, Ms. Christy was asked whether she could help get more people up to the observation deck. She said she couldn't get more people into a car but could move them up more quickly. So she increased the elevators' speed by 20%, to 20 feet per second. Now the cars can rise 80 floors in about 48 seconds, 10 seconds faster than before.

不久前帝国大厦(Empire State Building)投入5.5亿美元进行升级时，有人问克里斯蒂能否让更多的人上到观景平台。她说，她不能增加电梯轿厢运载的人员数量，但可以让电梯上升的速度更快。于是她将电梯的速度提高了20%，达到每秒20英尺（约6米）。现在电梯轿厢上升到80层楼只需大约48秒，比以前快10秒。

Ms. Christy strikes down one common myth─that 'door close' buttons don't work. Sometimes they do, sometimes they don't, she says. It depends on the building's owner.

克里斯蒂指出了一个常见的误区──关门按钮不管用。克里斯蒂说，电梯的关门按钮有时管用，有时不管用，这取决于建筑的所有者。

The challenges she deals with depend on the place. At a hotel in the holy city of Mecca in Saudi Arabia, she has to make sure that the elevators can clear a building quickly enough to get most people out five times a day for prayer.

她所面临的挑战随安装电梯的地点不同而不同。例如，在沙特阿拉伯圣城麦加的酒店里，她需要确保电梯能够迅速地把整栋楼的人运输下来，每天把基本所有人运上运下五次，满足他们的祈祷需求。
