Elevator Design Software and Elevator Analysis: A Guide for Engineers and Architects

The design of elevator systems for modern buildings sits at the intersection of mechanical engineering, traffic management, and architectural planning. It requires an understanding of passenger behaviour, building population dynamics, lift control systems, and the spatial constraints of the building’s core — and it requires tools capable of integrating all of these dimensions into a coherent design recommendation that the project team can rely on.

For engineers and architects navigating this discipline, AdSimulo provides a comprehensive platform for elevator performance analysis and design, covering traffic simulation, expert system optimisation, and the reporting and BIM output that professional practice requires. This guide explains what elevator analysis involves, why specialist software has become essential, and what the best tools provide.

What Elevator Analysis Involves

Elevator analysis, in its professional sense, is the process of modelling the performance of an elevator system under specific demand conditions to determine whether it meets the performance criteria appropriate for the building type and use. Performance criteria typically cover two primary metrics: handling capacity, which is the percentage of the building’s population that the elevator system can transport in a given time period, and average waiting time, which is the average time a passenger waits from pressing the call button to the elevator arriving.

These two metrics are evaluated against benchmarks that vary by building type. Office buildings have different performance expectations than residential towers, hotels have different peak traffic profiles than mixed-use developments, and high-rise buildings with large floor populations have different capacity requirements than low-rise structures. Professional elevator analysis uses the appropriate performance criteria for the specific building type and calibrates the proposed system design against these criteria.

The Lift and Escalator Industry Association LEIA represents the UK’s lift and escalator industry and provides guidance on industry standards, best practice, and the technical requirements that professional elevator analysis should address. LEIA’s members — covering manufacturers, installers, consultants, and maintenance organisations — represent the full spectrum of the vertical transportation sector and contribute to the standards framework within which elevator design professionals operate.

The Limits of Manual Calculation

Manual calculation methods for elevator analysis, based on the simplified traffic models that dominated the field before simulation became computationally practical, remain part of the professional toolkit for initial feasibility work. They provide quick, order-of-magnitude assessments that help architects and developers understand the lift core requirements of a building at an early stage, before detailed design has begun.

Their limitations, however, are well-understood within the professional community. Simplified calculation methods make assumptions about passenger arrival patterns, traffic distribution, and lift behaviour that are accurate for standard building types and conventional traffic control systems but become progressively less reliable as the building deviates from these standard profiles. For buildings with complex traffic patterns, non-standard floor populations, or advanced destination dispatch control systems, the discrepancy between calculated and simulated performance can be significant.

Simulation-based elevator analysis resolves these limitations by modelling the system’s behaviour directly. Rather than applying simplified traffic models, simulation traces individual passenger journeys through a statistical model of the building population, generating performance outputs that reflect the actual complexity of the system’s behaviour. The results are more accurate, more detailed, and more defensible in professional and contractual contexts.

What Elevator Design Software Should Provide

Professional elevator design software should address the full workflow of the elevator designer or consultant, from initial analysis through design optimisation to client reporting and BIM integration. The following capabilities define the current standard for professional tools:

• Multi-lift simulation that models the interaction between multiple elevator cars serving multiple floors under varied demand patterns, including up-peak, down-peak, inter-floor, and mixed traffic conditions
• Building type templates that apply the appropriate traffic parameters for different building categories — office, residential, hotel, hospital, mixed-use — without requiring the user to define these parameters manually for standard cases
• Expert system optimisation that evaluates multiple potential configurations systematically and recommends the optimal solution based on performance, space, and cost criteria
• 3D visualisation that allows the designer and client to observe the movement of passengers and elevator cars in a building model, providing an intuitive representation of the system’s performance that numerical outputs alone cannot convey
• Automated professional reporting that generates comprehensive documentation of the analysis, including the building parameters, performance criteria, configurations evaluated, and predicted performance of the recommended design
• IFC/BIM output that produces a Building Information Model of the elevator system in a format that can be incorporated directly into the project’s overall BIM environment

The Role of Elevator Design Software in the Design Process

Elevator design software is most valuable when it is engaged early in the design process, before the building’s core layout is committed to a specific configuration. The earlier the analysis is conducted, the more influence the results can have on the fundamental design decisions that determine the building’s vertical transportation performance: the number of lift shafts, their dimensions, their position within the core, and the number of floors served by each group of elevators.

Late engagement, after the core has been designed and structural elements committed, severely limits the designer’s ability to optimise the elevator configuration. Simulation at this stage can still confirm whether the proposed design meets performance criteria and identify the best available control system configuration, but it cannot address fundamental configuration constraints that have already been locked in.

Final Thoughts

Elevator analysis is a discipline where the quality of the tools directly determines the quality of the outcome. For engineers and architects who take vertical transportation performance seriously, specialist simulation software that combines analytical depth with practical workflow integration is not an optional enhancement but a professional necessity. Understanding the basics of rigorous elevator analysis — what it involves, what it produces, and how the results should inform design decisions — is the foundation of competent elevator design practice.
