What Factors Determine Number of Elevators A Building Requires

Commercial Elevator Services
Determining the number of elevators needed in a building is not a case of simple maths. The decision needs to be made considering several factors, including the building type, the expected footfalls and traffic pattern, the passenger waiting time, and more. Since an elevator is installed in a building during the construction stage, we have to work with an idea of general estimates rather than the actual numbers. The height of each floor, the number of floors, the design of the building, the purpose for which it is used, the usable area of each floor, all these factors determine the traffic the building is expected to experience. And building traffic is one of the very important considerations in finding the magic number for elevators.

So, firstly you have to estimate:

  • The size of the population that will be served by the elevator. The handling capacity of the elevator represents it
  • The maximum allowed passenger waiting time for an elevator.

Both these factors are interrelated. To get at a reasonable estimate, consider these questions objectively.

How to Decide the Right Number of Elevator Units for a Building

  • What building type is it? Is it a residential, commercial, or office complex? The type of building will shed light on how the elevator will be used, and that will help you decide whether you can have a small elevator for passengers and one service elevator.
  • What is the reasonable passenger waiting time you are ok with? Incorporate offices and hotels; they usually strive to keep in within 30 seconds; however, residential buildings are ok with a little longer waiting time. Remember lowering waiting time comes at a cost – like installing another elevator unit and all the maintenance fees that will incur in the future. Finding the balance is the key here.
  • What is the anticipated traffic pattern? Are there any peak hours of usage, or the traffic flow is uniform throughout the day?
  • How many floors are there in the building? How many stops will it be making between floors (because that increases the passenger waiting time)?
  • Who will be the primary users of the elevator? Is it students, senior citizens, or a mix of all kinds of users? You have to keep ADA compliance in mind as well.
  • What is the total area of the building being served? If it is a big complex like a mall, several additional units may be required as the elevator distance for users must be considered.
  • The number of elevators must comply with the local, state, and national building codes to be approved for use.
  • When you consider all these questions, you will get a lot of clarity about how many units of elevators are needed in the building premises.
