Abstract

Elevator technology has seen dramatic changes the last couple of years.

One of the most remarkable changes has been on the control algorithms side. The Introduction of the Intelligent Hall Call Destination Dispatching system has increased elevator efficiency tremendously, and has allowed a 20-25% reduction in the number of elevators required. Intelligent Hall Call Destination Dispatching has now also been introduced on Double Deck applications. A 52 storey office building, which earlier would have needed 24 single deck cars in 3 zones, can now be designed using only 2 zones with a total of only 13 Double Deck elevators, reducing the required core by no less than 11 hoistways.

Another remarkable change in elevator technology has been the application of Permanent Magnet Synchronous Motor technology. This technology with efficiencies up 96 % has allowed a dramatic drop in energy consumption of elevators. Where the elevators in a high-rise building could consume up to 8% of the total energy requirement 20 years ago, they nowadays only use about 2% of the total energy.

This paper will explain these technologies in a simplified way and how the above-mentioned benefits have been achieved.
