ORBi Open Repository and Bibliography
(146.867 recursos)
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

Models and prospects for a sustainable suburban transition. - Marique, Anne-Françoise; Reiter, Sigrid
This paper addresses the challenges, transformations and conditions of a sustainable suburban transition. Two powerful levers are used: (1) urban form, which is considered in addition to the individual building scale, and (2) mobility, because sprawl spatially separates activities, resulting in an increase in travel distances and energy used in transportation. Two main indicators (the heating needs of different types of suburban forms and a commute performance index) are developed and discussed. Three scenarios focused on the evolution of the existing building stock are modelled and assessed (the retrofitting of existing neighbourhoods, an increase in the built density and demolition...

Perspectives pour une transition durable des territoires périurbains. - Marique, Anne-Françoise; Reiter, Sigrid
L’article traite de la transition durable des territoires périurbains. Deux leviers d’action sont mobilisés à cette fin: (1) la forme urbaine et (2) la mobilité. Trois types de scénarios centrés sur une évolution du stock bâti existant sont modélisés et évalués (la rénovation énergétique, la densification et la démolition/reconstruction) de façon à répondre à deux questions : « comment intervenir dans les quartiers périurbains existants? » et « où intervenir? ». Ces simulations montrent que le renouvellement périurbain par densification des quartiers les mieux localisés permet de dépasser le clivage traditionnel entre les modèles de la « ville compacte »...

Development of riveting technology through an analysis of Belgian patents (1830-1940) - Collette, Quentin; Wouters, Ine; de Favereau, Corentin; Peters, Arnaud
The development of riveting technology in iron and steel structures in the 19th and 20th centuries were highly promoted by patents. Although riveting was widely used in buildings and civil engineering structures, little information about the development of this technology – how rivets were manufactured, various installation techniques – is available in literature. This paper discusses a database of patents related to riveting technology that was created to better understand the innovations in riveted connections and their technological evolution. The database includes patents relating to rivets registered in Belgium between 1830 and 1940.
Belgian patents are a good proxy for...

Passive designs and strategies for low-cost housing using simulation-based optimization and different thermal comfort criteria - Nguyen, Anh Tuan; Reiter, Sigrid
An optimum design of low-cost housing offers low-income urban inhabitants great opportunities to obtain a shelter at an affordable price and acceptable indoor thermal conditions. In this paper, the design and operation of a low-cost dwelling were numerically optimized using a simulation-based approach. Three multi-objective cost functions including construction cost, thermal comfort performance and 50-year operating cost were applied for naturally ventilated and air-conditioned buildings. Thermal environment inside the house was controlled and assessed by two thermal comfort models. Optimization problems which consist of 18 design parameters and 6 ventilation strategies were examined by two population-based probabilistic optimization algorithms (particle...

Sustainable housing in Vietnam: Climate responsive design strategies to optimize thermal comfort - Nguyen, Anh Tuan
Housing issue in Vietnam is still a big concern as in 2008, 72.2% of the existing housing was semi-permanent or temporary and 89.2% of the poor did not have a permanent shelter. As a response to sustainability, the global aim of this thesis is to develop design strategies toward comfortable, energy-efficient housing with acceptable building cost. Occupants’ thermal comfort is the key assessment criterion throughout the research.
First of all, the thesis develops a thermal comfort model for Vietnamese people living in naturally ventilated buildings through the data from field surveys around South-East Asia. This comfort model is then...

Les marbres dans les traités d’architecture français des XVIIe et XVIIIe siècles - Gilles, Isabelle
Les traités d’architecture français reflètent parfaitement l’intérêt plus ou moins appuyé pour les marbres tout au long de l’Ancien Régime. De Philibert de l’Orme à Nicolas Le Camus de Mézières, nous ferons un rapide tour d’horizon du discours sur les marbres ; discours dans lequel apparaissent des questions de provenance, de couleurs, de mise en œuvre... mais également d’usage. Nous envisagerons ainsi les emplois particuliers des marbres. En effet, dans la théorie architecturale, le choix des matériaux — que la matière soit réelle ou imitée — doit répondre à des principes bien établis, autour des notions de convenance et de...
