In some buildings - especially Class A offices, the speed of elevators can be key way to set one building apart from another.
One way to improve elevator efficiency is to employ a destination dispatch system. In a destination dispatch system, occupants enter their destination floor instead of using push buttons in a lobby. The dispatch system then picks the most efficient elevator to carry the passenger — which may not be the next arriving one. The speed of the elevators doesn't change, but grouping destinations improves performance compared to a traditional dispatching system. The end result is reduced wait times for occupants.
Destination dispatch could improve handling capacity by as much as 25 percent, experts say. That can be especially important in older buildings where occupancy has grown over time.
