User Requirements of Elevators CBD-190. As elevators are the primary means of vertical movement in many buildings, they should be built to satisfy the requirements of most users. This Digest discusses these requirements and the options available.
Most users require no more than a service that is comfortable, safe and relatively efficient.
As comfort is determined by both environmental and psychological aspects, elevators should be ventilated and well maintained. Relative efficiency of service should relate to the type of building and is normally evaluated in terms of average waiting time. Table 1 indicates the waiting times assumed to be acceptable for various buildings. Acceptable waiting time is a value judgment based in part on an estimate of the cost of the time lost in waiting. Consequently, in residential situations a longer waiting time is more acceptable than in a working environment.
