This method is supported by a toolset and is being deployed on real construction projects in France. BIMetric aims to define a project-level structured method, enabling to assess the BIM ROI among project partners and projects’ workflows implementing BIM (BIM uses). sharing of benefits among the design/construction/facility management chain. Return on Investment) is not well define nowadays, especial ly when it comes to projects’ organizations, i.e. Implementing BIM internally in organizations or in AEC projects’ teams remains a strategic investment. An automatic routine for exporting TRNSYS types from the TRNSYS Simulation Studio is presented as well as validation examples for the coupling.

The paper illustrates the methodology for calling TRNSYS types within Matlab or Simulink and gives advices for integrating those models into existing model assemblies. Almost any TRNSYS model can be used in the Simulink environment in this way. This paper describes a methodology to export the models contained in the TRNSYS model library as well as non standard models (calles 'types' in TRNSYS terminology) into the Simulink environment, and to use them in a Simulink model assembly. The same system and building is thus modelled several times in order to be able to simulate in the different environments.

Collaborative work is sometimes time-consuming since, in the different steps of building and system conception and optimization, different tools have to be used, each of them specifically dedicated to a particular problem: for example the overall conception of a building can be done using the TRNSYS simulation environment, while optimization of control strategies is likely to be done using the Matlab/Simulink simulation environment. A large variety of simulation environments exists for building and system simulation.
