Existing building Data collection and download based on IFC model definition (BACN2BIM)

Management Summary

This document aims at describing 'Existing building Data collection and download based on IFC model definition' use case which is implemented as part of BIM-SPEED EU Horizon2020 project, under grant agreement No. 820553, https://www.bim-speed.eu/en using the BACN2BIM tool, developed by CARTIF https://www.cartif.es/en/. This use case allows obtaining and storage of building monitoring data of the devices installed in the building, and update the IFC file of the building including the sensors information of the Building Automation and Control Network.


Use Case Definition

 

Aim and scope

The ‘BACN2BIM Tool’ implemented as part of BIM-SPEED project is developed with the need for the objectives set by the BIM-SPEED Project. It helps in:

  • Time reduction in the process of downloading data from different sources
  • Generate the new BIM model IFC based including information on the monitoring systems installed on the buildings.

Objectives

This tool aims to allow users to download data from different demo sites from just one platform. Many times when users desire information about the behaviour of different buildings they do not have the possibility to do it and many other times they have to connect to different monitoring systems to download data in different formats. Using the BACN2BIM tool users have the possibility to set up monitoring systems as part of the BIM-SPEED platform, allowing the download of data from devices as well. The tool also updates the IFC file with information about the devices that compound the monitoring system, enabling their visualization in BIM software tools.  The use of this tool offers the users the following benefits:

  • Time reduction: Users can download data from different demo sites just from one single platform. All data are stored with the same format.
  • Update BIM model: the IFC file is automatically updated containing information on the monitoring systems. Users have the possibility to see where devices have been installed and/or modify the location or design.

 

The image below shows comparison of BIMSpeed approach with the conventional practices in the BACN to BIM process. 

Limitations

The tool inserts devices in an arbitrary wall in the related space. Firstly users have to set up and create a configuration file in order to be available to create new monitoring project and download data.
