Circulation Analysis - International

Management Summary

To plan sustainable buildings with respect to long term maintenance and future development, crowd simulation tools can be used in order to check buildings in the early planning phase for their designated usage. These simulations are used to check whether performance indicators are fulfilled and the building is compliant.

To perform such analysis automatically, the model has to provide specific information on top of geometric information. For that, the current IFC model has to be extended.

The key actors on this project are the Owner, the Simulation Expert as well as the Planner.

The aim of this project to perform circulation analysis throughout the design phase in a repetitive manner to enhance the overall planning process.


Use Case Definition

Circulation analysis is relevant during the planning and lifecycle process of buildings. For a variety of different building classes such as airports, high rise buildings, or railway stations, the functionality of such buildings must be assured and laid out sustainably for long term maintenance and future development. Conducting occupancy movement analysis thus offers a deep insight into the buildings' functionality and allows quick and affordable digital prototyping, avoiding costly planning errors.

Aim and scope

The aim of this project is to develop an IDM to see what information is needed for crowd simulations. This information will be added to the IFC Model in order to enable automatic extraction of the relevant data and simulation.


  1. Identify the actors and stages involved in the design phase.
  2. Identify the workflow for circulation analysis.
  3. Identify data exchange requirements to carry out circulation analysis using modeling tools.
  4. Identify current IFC support for data exchange and limitations, together with areas for improvement.
