After reviewing current trends in thermal simulation, it outlines major criteria for the evaluation of building thermal simulation tools based on specifications and capabilities in interoperability. Details are discussed including workflow of data exchange of multiple thermal analyses such as the BIM-based application. The present analysis focuses on selected thermal simulation tools that provide functionalities to exchange data with other tools in order to obtain a picture of its basic work principles and to identify selection criteria for generic thermal tools in BIM. Significances and barriers to integration design with BIM and building thermal simulation tools are also discussed.

This paper combines the principle of integration for thermal calculation and scientific visualization in VR. The method is to use CAD models (extensively used in architectural design) to analyze a building's thermal performance and visualize it, as well as simulating it through VR technology. Interaction between users and objects in a virtual world are certainly through techniques of visualization metaphors. The object of the experiment was the Gunzo room, located in an old building on the historical site of the Cluny Abbey in France. An application and an experiment scenario of a thermal simulation was created to interactively visualize the results in the immersion room, and tested by some participants. The experiment was conducted to simulate object-based data models that are specific to the thermal domain, using tools provided by the IFC format. This choice was made to overcome the limitations of general-purpose geometric representations, particularly in data exchange among the selected tools used for the simulation. Analyzing the application has demonstrated that it is possible to conduct a specific data workflow in order to represent building performance data, and particularly thermal simulation results in VR. With this integration method, the data flow that starts from the design process is completely and accurately channeled to the VR system.

Focusing on thermal efficiency, the renovation proposal dealt with the great windows. We compared three methodologies dedicated to the project planning and management We first address the issue of the renovation of old buildings and come up with a workflow that connects the digital building to its lifecycle; then we focus on an instance of onsite handling of such data, in an augmented reality context, by elaborating the notion of “BIM in situ” as described in the papers of [3] as well as in [4]. Results reveal that handling BIM onsite through a mobile device is challenging but they also show that it brings more efficiency.

The importance of energy efficiency and integration of advances in building design and VR technology have lead this research to focus on thermal simulation results visualized in a virtual environment to optimize building design, particularly concerning heritage buildings. The emphasis is on the representation of thermal data of a room simulated in a virtual environment (VE) in order to improve the ways in which thermal analysis data are presented to the building stakeholder, with the aim of increasing accuracy and efficiency. The approach is to present more immersive thermal simulation and to project the calculation results in projective displays particularly in Immersion room (CAVE-like). The main idea concerning the experiment is to provide an instrument of visualization and interaction concerning the thermal conditions in a virtual building. Thus the user can immerge, interact, and perceive the impact of the modifications generated by the system, regarding the thermal simulation results. The research has demonstrated it is possible to improve the representation and interpretation of building performance data, particularly for thermal results using visualization techniques.
