Circulation Analysis - International

To plan sustainable buildings with respect to long term maintenance and future development, pedestrian modelling 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.

The key data exchanges and interactions between the key stakeholders are captured by the process map.

Conducting circulation analysis (occupant movement analysis under in non-emergency situation) offers a deep insight into the buildings' functionality and allows quick and affordable digital prototyping, avoiding costly planning errors. It is relevant during the planning and lifecycle process of buildings, particularly for complex buildings.

Input data requirements were captured based on a review of seven representative pedestrian modelling tools and were documented in an Excel spreadsheet. Based on these requirements, an IDS file was created for checking input data requirements. A sample hotel model was then created and used to check the data requirements using the IDS file. These were the key requirements of this use case, which were successfully demonstrated using the sample hotel model through an openBIM based workflow. Furthermore, the following additional work was undertaken and demonstrated:

• Importing the hotel model IFC file into a representative pedestrian modelling tool (buildingEXODUS),
• Capturing and adding the key analysis results to the sample hotel model,
• Checking the sample hotel model IFC file containing output data requirements (i.e. analysis results) with another IDS file specifically developed for this purpose. 

The aim of this use case is to achieve an openBIM based workflow for circulation analysis.

To achieve this aim, the following objectives were identified:

• Develop a process map for circulation analysis (non country specific)
• Identify data exchange requirements to carry out circulation analysis using pedestrian modelling tools.
• Identify current IFC support for data exchange and limitations.
• Produce a list of data requirements including new property sets and properties.
• Create an IDS file to check the data requirements.
