Une partie de ces éléments nous est parvenue grâce aux fouilles archéologiques et a permis de proposer des hypothèses de restitution. Le parti général était celui de représenter l’église dans son état à la fin du xve siècle, sans tenir compte des reprises plus tardives. Nous avons tenté de réunir les connaissances actuelles sur chacun des éléments pour proposer une restitution en 3D du chœur 2, de manière à le présenter sur un écran et dans un film, au cours de la visite sur le site. Il en résulte des images, qui seront amenées à évoluer au fur et à mesure des nouvelles découvertes dans les prochaines années.

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.

The third church of the Abbey of Cluny (12th c.) has been destroyed after the French Revolution, leaving only 8% of the building standing. Many documents have been studied, to include the latest archaeological knowledge in the virtual model. Most remains have been scanned for CAD restitution. The mock-up of the church needed 1600 different numerical files, including the scanned pieces and the anastylosis of a Romanesque portal, a Gothic façade and a mosaic pavement. We faced various difficulties to assemble the different elements of the huge building, and to include the digitized parts. Our workflow consisted in generating geometrical shapes of the church, enriched with metadata such as texture, material... The whole mock up was finally exported to dedicated software to run the rendering step. Our work consisted in creating a whole database of 3D models as well as 2D sources (plans, engravings, pictures...) accessible by the scientific community. The scientific perspectives focus on a representation in virtual immersion of the grand church at scale 1 and an access to the digital mock-up through Augmented Reality.

In one of these projects, the Gunzo project went through a complete digital restitution of what was the largest church in the world during five centuries. In another project, a 3D GIS of the Cluny region was set up and led to the idea of designing an online historical and archaeological 3D database. This involves the development of time-based 3D data management functionalities in which both CAD and GIS could exchange information. Thanks to the close collaboration between interdisciplinary fields, the team managed to formulate the basis of a joint workflow. These steps are promising and could meet in the future this long-time dream of the scientific community: to be able to tie together CAD and GIS models with temporality on a single georeferenced collaborative platform, so closely that it will be possible to navigate through the history of a city in 3D.

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.
