Flexible elevator configurations

This talk explores the benefits of flexible elevator configurations that increase effective traffic efficiency by load balancing, provide direct service between a wide range of floors and provides futureproofing for tenants leasing multiple floors in a building.

Tall buildings typically have multiple banks of elevators where each bank serves a block of floors where the set of floors served by one bank is disjoint from any other bank other than a common main lobby. Partitioning the elevators into separate banks simplifies the elevator controls with an independent dispatcher for each bank and reduces core space since not all elevators span the full rise of the building.

However, this partitioning only allows "direct service" between floors within the same bank but if a passenger wants to travel between floors in different banks, the passenger must first travel to a common transfer floor (often the main lobby) and take a second elevator to the destination floor. As tenants desire direct service between floors that they occupy, this restricts their options when they wish to lease more space.

This talk proposes layouts configured where some elevators serve floors in more than one traditional bank. These layouts enable direct service between any pair of floors and also can balance elevator traffic between banks so that the elevators that serve more than one bank can be directed towards the busiest bank. The key enablers are destination-entry interfaces where a passenger is assigned a specific elevator based on the destination floor as well as a new type of dispatcher that effectively treats the separate banks as a unified-bank and manages elevator traffic for the entire building rather than in separate banks.
