| The headquarters building of the American Association for the Advancement
of Science in Washington, DC, has many innovative energy-saving and environmentally-friendly
features. Among them is a state of the art elevator system that groups
passengers by destination floor before they get into the elevators. Instead
of pushing an "up" or "down" button, a user enters the floor to which he
or she is going on a key pad in the elevator lobby. An LCD screen
then tells the user which elevator to take. The system also
uses "fuzzy logic" to track usage patterns for each floor during the day
and pre-programs the elevators to wait at certain floors at peak times,
so that they can respond more quickly. The system both reduces waiting
time and saves energy.
Here's an analogy that the manufacturer, Schindler Elevator Corporation, uses to describe the operation of the system: "Every day, thousands of people arrive at London's Heathrow airport wanting to travel to Brussels, Paris, Frankfurt, Zurich, Vienna and Rome. Each of these destinations can be reached in under two hours. But imagine how long it would take to get to Rome if the plane stopped at all the other airports en route. Airlines, not unreasonably, group passengers together into individual planes according to their destination. Miconic10® does exactly the same for the travellers in a building." Although visitors who have never seen such an elevator system (there are only a few in existence), often find it confusing, most of the employees in the building enjoy the lack of long waits and the "express service" to their floors. The downside? In grouping people by destination, the elevators tend to reduce casual contacts among people who work on different floors. This makes it harder for people who work in different parts of the organization to get to know one another. |
