Elevators typically have service lives of over 20 years, but over time their performance can begin to decline. When that happens, it might be time to consider modernization.
Modernization might not increase the speed of elevators, but it can increase their efficiency. Modern elevators with destination dispatch technology can group passengers by where they are going, eliminating wasted trips and reducing wait times. Microprocessors can learn traffic patterns in a building and adjust accordingly. Modern elevators can have improved acceleration and deceleration rates, and doors can open and close faster.
Modernization can also make elevators more energy-efficient and reduce energy costs. They can feed energy back into the building as they descend, rather than releasing it in the form of heat. That can reduce the amount of energy needed to keep the machine room cool.
Elevator modernization can reduce electromagnetic noise. This can be helpful because computers and wireless networks are sensitive to it. Solid-state elevator drives vary in terms of the amount of electromagnetic noise they produce.
Elevator modernization can affect electrical performance. An older generator might not be compatible with a new solid-state drive because drives do not tolerate variations in power quality well.
