CIMEDE is a wooden industrialized building system focused on modularity, sustainability and cost effectiveness. This paper presents an applied research project focused on the implementation of software able to efficiently assist the various stakeholders involved in the design and the construction of CIMEDE housings (architects, clients, process managers, builders, factory workers...). The main objective is to develop an easy to use and bespoke 3D CAD modeler addressing the multiple stakeholder’s needs, and able to integrate the whole complex process of industrialization. [less ▲]

Some advice for migrating to IFC

Nowadays, the BIM (Building Information Modeling) paradigm is a central topic in the CAAD community. Next to the commercial solutions, the IFC (Industry Foundation Classes) have emerged as the best open standard candidate for BIM interoperability. Despite the efforts of the community for promoting IFC over the last 15 years, it seems that its practical adoption in real-life projects has been very limited. The goal of this article is to explore how useful IFC can be today and to provide the reader with some advice for an effective adoption of IFC. Over the last year, we have conducted a project aiming at acquiring a sound understanding of IFC. It was made of two complementary investigations. On one hand, we have focused on the commercial modeling tools and the IFC support they were offering. On the other hand, we have focused on the IFC-based software developments. We have developed a tool converting IFC files into a dedicated thermal assessment based model. We will summarize the experience we have acquired in this project into some advice for users migrating to IFC. Our goal is to confront the practical aspects of the IFC developments, with both the theoretical ambitions and the commercial support currently available. [less ▲]

PEB: thermal oriented architectural modeling for building energy efficiency regulations

Poster (2011)

As part of the overhauling of the building energy efficiency regulations (following European directive 2002/91/CE), the Wallonia and Brussels-Capital Region commissioned the LUCID to develop an optional ... [more ▼]

As part of the overhauling of the building energy efficiency regulations (following European directive 2002/91/CE), the Wallonia and Brussels-Capital Region commissioned the LUCID to develop an optional 3D graphic encoding module to be integrated with the core energy efficiency computation engine developed by Altran Europe. Our contribution consisted mostly in analyzing the target users’ needs and representations (ergonomics, UI, interactions) and implementing a bespoke 3D CAD modeler dedicated to thermal models of buildings taking into account the various geometrical and relational constraints specific to thermal modeling.

Mixed Reality Prototypes to Support Early Creative Design

Many complex IT projects are still primarily focusing on today's technological challenges. The adaptation of the core technologies to potential applications often occurs in a second stage where the end-users are involved. We describe a different approach, involving the users at the very beginning of the development. The domain we address is the creative design, mainly architecture. Rooted in a multidisciplinary approach as well as a deep understanding of architecture and design, our method aims at proposing adapted mixed reality solution to support two crucial activities : sketch-based preliminary design and distant synchronous collaboration in design. This chapter provides a summary of our work on a mixed-reality device based on a drawing table (the Virtual Desktop) designed specifically to address real-life/trade-focused issues. We explain our methodology, describe the two supported activities and the related users’s needs, we detail the technological solution we have developed and we present the main results of the multiple evaluation sessions. We then conclude on the usefulness of the profession-centered methodology and on the pertinence of the mixed reality to support creative design activities. [less ▲]

Budd-Chiari Syndrome Complicating Hepatic Sarcoidosis: Definitive Treatment by Liver Transplantation: A Case Report.

in Transplantation Proceedings (2009), 41(8), 3432-3434

Sarcoidotic involvement of the liver is frequent, albeit uncommonly symptomatic. Severe complications are rare, but may seldom require liver transplantation. Budd-Chiari syndrome has been described in a few patients with hepatic sarcoidosis. Herein we have reported the case of a young woman suffering from hepatic sarcoidosis who developed severe cholestasis and chronic Budd-Chiari syndrome. She successfully underwent orthotopic liver transplantation (OLT) and is asymptomatic with normal liver function at 3 years follow-up. Histopathological assessment of the liver explant demonstrated a florid granulomatous process, with involvement of the large intrahepatic veins, providing an anatomical basis for the vascular flow disturbances. This case adds further evidence that liver transplantation may be the curative treatment for complicated sarcoidotic liver disease. [less ▲]

Distributed Collaborative Design Studio : a sketch-based environment to support rich distant collaboration. Workshop.

An increasing number of large scale projects requires that distant teams collaborate together remotely. At the same time, the current CAD tools only offer minimal support for partial and asynchronous interactions. The application we propose enables full synchronous and remote sketch-based collaborative design. This setup is a combination of a virtual desktop (a remote meeting table), a standard videoconference system, a gesture recognition module and a networked, real-time, collaborative drawing software (SketSha). The solution as a whole is multimodal in essence (gestures, speech, drawing…) supporting immersive remote collaborative design. [less ▲]
