What does "elevator density" refer to in building design?

Elevator density refers to the ratio of elevators to the number of floors or occupants within a building. This concept is crucial in building design, particularly for tall structures or those with high foot traffic, as it helps to ensure efficient vertical circulation. A higher elevator density means more elevators are available per floor or per number of residents/users, which enhances convenience and minimizes wait times.

In a well-designed building, this ratio is carefully calculated to accommodate the expected traffic patterns throughout the day, especially during peak hours. Therefore, having an adequate elevator density is fundamental in improving the overall functionality and user experience in multi-story buildings.
