With socio-economic development, more and more high-rise buildings are emerging in cities, and elevators, as a necessary tool in people's daily lives, have become indispensable. A ​​low number of elevators, slow speeds, and low rated load capacities in a building will fail to meet the needs of its occupants; conversely, an excessive number of elevators, excessively high speeds, and oversized rated load capacities will lead to resource waste and inefficient elevator utilization. Therefore, before building construction begins, elevator selection is crucial to providing fast, convenient, economical, and comfortable elevator service to the building's occupants. Volkspace, as a professional elevator manufacturer, provides a scientific and effective method to effectively address the problem of elevator selection and configuration before building construction.

Number of Elevators and Their Passenger-Serving Capacity

All calculations of elevator system traffic capacity depend on multiple factors, which vary depending on the elevator design and the assessment of passenger behavior. The number of elevators installed in an existing building and their passenger-serving capacity typically depend on the following factors, including:
(1) The number of floors the elevator serves;
(2) The height of each floor;
(3) The number of passengers served on each floor;
(4) Peak demand, which can be unidirectional or bidirectional, and the demand during peak or off-peak hours.

For office building elevators, the following methods can serve as basic guidelines for initial elevator planning, and the principles can also be applied to other types of buildings. For office building elevators, the elevators should be designed according to the specified ratio of the building's occupancy, and the following three main factors should be considered:

(1) The number of people in the building or the number of people who need to use the elevator.
(2) Elevator capacity or service frequency (the maximum arrival rate required by building occupants).
(3) Average passenger waiting time or required service frequency (usually expressed as the average interval between elevator arrivals).

Estimates of passenger numbers, arrival rates, and intervals.

The round-trip time of a single elevator during peak upward travel periods.

H - the average highest return floor;
d_f - the average height between floors;
v - rated speed;
S - the average number of possible stops;
t_c - door closing time;
t_f(1) - travel time for a single floor;
t_o - door opening time;
P - the average number of passengers in the elevator car;
t_p - the average time for passengers to enter and exit the elevator car.

For buildings with 5 to 13 floors above the main floor served by elevators, according to BS ISO 4190, with the elevator car fully loaded, H and S can be calculated from Table 2. In Table 2, P is usually assumed to be 80% of the elevator's rated load capacity CC.

t_c + t_f(1) + t_o represents the completion time T, which is the time from the moment the door begins to close until the door opening width at the next adjacent floor reaches 800mm. For advanced systems, the completion time is typically 8.0s for a floor height of 3.3m, 10.0s for standard systems, and 12s for less efficient systems. The elevator manufacturer can provide this data.

The H and S values ​​corresponding to the rated load capacity.

t_p represents an estimated value. In busy office buildings, this value is typically 0.8 seconds, while for special locations such as nursing homes, it is usually 2.0 seconds. The average passenger entry and exit time tp can generally be assumed to be 1.2 seconds. 

Use Equation (2) to calculate the peak interval time for a group of elevators (L) during upward travel.

Equation (3) can be used to calculate the peak upward transportation capacity of a group of elevators L (calculated as the number of passengers per 5 minutes).

Determining the Elevator Car Dimensions

If the target system's peak upward traffic capacity HC and peak upward interval time t_INT are known, they can be used to estimate the required elevator rated load capacity CC. For example, if the required interval time is 30 seconds and the required traffic capacity is 100 people every 5 minutes, the rated load capacity of the elevator car can be calculated as follows.

Number of runs within 5 minutes: 300/30 = 10 times.
Number of passengers per elevator trip: 100/10 = 10 people.
Elevator rated capacity CC: 10/0.8 = 12.5 people.

The closest standard elevator car dimensions conforming to BS ISO 4190 (all parts) have a rated capacity of 13 people; therefore, 13 people × 80% = 10.4 people.

For data analysis purposes, when determining elevator dimensions, it is assumed that the elevator car carries an average of 80% of its maximum load during each trip.

Calculation example for elevator configuration

Assume a building has 10 floors, with a floor-to-floor distance of 3.3m. The rated speed is typically chosen as 1.6m/s, and the travel time between floors is 10 seconds (obtained from the elevator manufacturer). The passenger waiting time for the elevator is 30 seconds, and the building requires a transportation capacity of 100 people every 5 minutes, with the elevator serving all 10 floors. From the above data, we can conclude:

P = 10.4 people (13 people × 80%, as shown in Table 2).
H = 9.5 (as shown in Table 2).
S = 6.7 (as shown in Table 2).
tp = 1.2s (assumed).

Calculated according to formula (1).

Since the number of elevators must be an integer, it is necessary to use a round-trip time of 125.3 seconds. Dividing by this integer, the resulting interval time is approximately 30 seconds. Choosing 5 elevators, we can then calculate the peak-hour interval using Equation (2).

Use Equation (3) to calculate the peak upstream transport capacity (number of people per 5 minutes).

Therefore, installing four elevators in the building (each with a capacity of 13 people) would be most suitable.

Volkspace provides scientific and reasonable recommendations for the selection of new passenger elevators, offering effective selection solutions to stakeholders such as building clients, builders, contractors, building owners, developers, and engineering consultants in the early stages of construction. This helps maximize the functionality and improve the operational efficiency of the elevators, thus generating positive results.
