Elevators are the enablers of vertical transportation and traffic management through tall buildings. They are mission-critical elements needed to keep the people and material flow into and within urban habitats. Therefore, a flawless operation is the minimal requirement to be fulfilled. On the other side, there are several differentiating elements related to the performance achieved by vertical transportation. Elevators should serve a call in as little time as possible, with a maximum of ride quality and thereby consume as little energy as possible. These high demands are typically not independent, and often contradictory, which renders their optimization a complex task. These different aspects are often separately and singularly optimized, depending on specific customer requirements. A new and different approach implies the usage of complex modeling and optimization algorithms.

In this context, the Elevator Dynamic Environment “EDEn” has recently been developed. It is a mathematical and physical description of the relevant dynamic effects of the elevator components and systems. EDEn is highly parameterizable, whereby it allows simulation and investigation of the performance (e.g. ride quality, temporal behavior, and energy consumption) of various elevator configurations. In this presentation, EDEn is used to assist the optimization of elevator component and system design for tall buildings. Its simulation results serve as a basis for a sensitivity analysis, answering the question, “How have the different design parameters affected the performance, and how they are linked?”
