This paper analyses the impact of territorial structures upon energy consumption in the Walloon Region (Belgium). The rationale for this research is to consider the long-term influence of spatial planning decisions upon energy consumption in both residential building stock and home-to-work commuting. The analysis has been conducted on a regional scale (16,844 km2) and includes urban, peri-urban and rural settlements. Those settlements that perform well in mobility also appear to perform well in terms of building energy consumption. Even though this is not generally the case, it further reveals that some rural settlements characterized by low density show good performance in terms of energy efficiency. This permits a much more progressive approach in terms of spatial planning, whereby compact cities may be viewed as part of the solution, albeit not the whole solution. [less ▲]

The limited semantics of thesauri and similar knowledge models hinder the searching and browsing possibilities of the bibliographic databases classified with this type of resources. This work proposes an automatic process to convert a knowledge model into a domain ontology through the alignment with DOLCE, an upper level ontology. This process is facilitated by an intermediary alignment with Wordnet, a lexical model. The process has been tested with the thesauri and bibliographic databases of Urbamet and the European Urban Knowledge Network. The Urbamet model has been used to create an atlas of urban related resources with advanced search capabilities. [less ▲]

Dans les dernières décennies, on peut observer chez différentes agences internationales un intérêt croissant pour les méthodologies d’observation et les indicateurs urbains. Dans le monde arabe, ces agences sont un acteur influent contribuant au développement des politiques urbaines, notamment à travers la circulation des outils, méthodologies et bonnes pratiques. UN-HABITAT, en particulier, contribue à cette logique de propagation en mettant en place un nombre d’observatoires urbains locaux qui s’inscrivent dans son réseau d’Observatoire Urbain Global. La dynamique recherchée par ce réseau est surtout l’encouragement des villes à œuvrer dans le sens des Objectifs de Développement du Millénaire et de démarches d’Agenda 21, notamment à travers la mise en avant de l’importance d’un certain nombre d’indicateurs. Notre intervention revient sur les observatoires urbains locaux dans le monde arabe, et en particulier leur appropriation des indicateurs et méthodologies d’UN-HABITAT. Malgré l’effort de systématisation déployé par l’agence internationale, l’articulation entre observatoires et action publique territoriale reste très variée. Deux facteurs influent conjointement sur cette articulation et sur la façon dont l’appropriation des indicateurs et méthodologies de l’agence se fait : la taille et les moyens de l’observatoire, et le rôle qu’il joue dans la gouvernance urbaine. Nous nous appuyons sur des entretiens avec des acteurs de ces observatoires, la participation à des réunions organisées par la commission économique et sociale d’Asie de l’Ouest (UN-ESCWA) autour des observatoires urbains en présence de représentants de ces observatoires et d’UN-HABITAT, ainsi qu’une revue de la documentation produite par tous ces acteurs. On distingue trois situations. On voit, d’abord, les petits observatoires n’ayant pas les moyens de produire tous les indicateurs d’UN-HABITAT, comme celui de Sin-El-Fil dans les banlieues de Beyrouth, bricoler leurs propres indicateurs et méthodologies pour répondre plus directement et avec leurs ressources aux priorités des municipalités dont ils dépendent. Ceci est aussi le cas d’observatoires mis en place dans une perspective de renforcement des capacités managériales des acteurs dans un contexte de construction de politiques ou de projets stratégiques métropolitains, comme à Amman, Alep et Tripoli. Ces observatoires, tout en récupérant certains indicateurs de la liste d’UN-HABITAT, se focalisent sur les indicateurs qui permettraient d’avancer sur les questions stratégiques qui les préoccupent et d’ouvrir la discussion entre les partenaires. Par contre, d’autres observatoires, comme ceux de Jeddah et de Medina, reprennent largement les indicateurs d’UN-HABITAT. Cependant, ces observatoires, bien que très bien dotés financièrement et en ressources humaines, jouent surtout le rôle de « vitrines » de modernité pour les administrateurs de ces villes, mais n’influent que marginalement sur l’espace de prise de décision.

The present structure of harbours in the Walloon region hardly fits the needs of present logistic developments. Considering the challenges for the development of fluvial transport, the Walloon public authorities decided in 2010 to indentify potential harbour development sites along its 440 kms of waterways. A three steps approach (selection, ranking and documentation) was designed for this purpose. This paper broaches the methodology and the results of this approach. The area of sites and their availability, which were considered as most debatable during the research, are specifically discussed. [less ▲]

Built environment is responsible for 60% of total energy consumption in European countries and 128 million BOE of primary energy in Belgium. The average energy consumption in the residential buildings of Belgium is 70% higher than the EU average and stands at 348 kWh/m2/year. Energy Performance Building Directive (EPBD) provides guidelines for energy performance analysis of buildings in Belgium. In this study, a holistic approach has been adopted to analyse the building stock of Liege, Belgium. This analysis is based on ‘General Socio-economic survey 2001’ and ‘Housing quality survey 2006 in Walloon region’databases. It considers parameters such as buildings age, built-up area, type of heating system, type of fuel used, adjacency, insulation of roofs and walls and energy consumption etc. for an in depth analysis. This study concludes that about 69% of buildings which are constructed before 1945 needs serious renovation towards the improvement of roof and external wall insulation level. It then successfully identifies specific areas which need detailed study to evaluate the comfort status in the existing building stock, improvement of insulation level and its effect on heating energy consumption as well as the economic analysis on energy efficiency measurements.

Managing flood risk in Europe is a critical issue because climate change is expected to increase flood hazard in many european countries. Beside climate change, land use evolution is also a key factor influencing future flood risk. The core contribution of this paper is a new methodology to model residential land use evolution. Based on two climate scenarios (“dry” and “wet”), the method is applied to study the evolution of flood damage by 2100 along the river Meuse. Nine urbanization scenarios were developed: three of them assume a “current trend” land use evolution, leading to a significant urban sprawl, while six others assume a dense urban development, characterized by a higher density and a higher diversity of urban functions in the urbanized areas. Using damage curves, the damage estimation was performed by combining inundation maps for the present and future 100 yr flood with present and future land use maps and specific prices. According to the dry scenario, the flood discharge is expected not to increase. In this case, land use changes increase flood damages by 1–40 %, to EUR 334–462 million in 2100. In the wet scenario, the relative increase in flood damage is 540–630 %, corresponding to total damages of EUR 2.1–2.4 billion. In this extreme scenario, the influence of climate on the overall damage is 3–8 times higher than the effect of land use change. However, for seven municipalities along the river Meuse, these two factors have a comparable influence. Consequently, in the “wet” scenario and at the level of the whole Meuse valley in the Walloon region, careful spatial planning would reduce the increase in flood damage by no more than 11–23 %; but, at the level of several municipalities, more sustainable spatial planning would reduce future flood damage to a much greater degree.

Indoor thermal environment monitoring has been done in 20 residential buildings of Liege city followed by questionnaire based comfort survey amongst the occupants of 85 houses in order to record their preference and expectations about indoor thermal environment in winter and spring season. It is found from the analysis that change of glazing has a minimum or even sometimes an adverse effect on the existing indoor environment due to the absence of proper insulation of the rest of the building envelope. It is observed that in winter there is a sudden drop in indoor temperature and also overheating in summer. This is due to unplanned installation of glazing which actually increases the fenestration area ratio leading to higher indoor temperature fluctuation and causes discomfort. It is also important that the occupant’s preference and expectations as well as overall assessment of indoor environment needs to be consider towards energy efficiency improvement. [less ▲]

A detailed study on the building stock of Liege urban area (Belgium) has been conducted during 2011-2012. The study is focused on historic buildings, which were constructed before 1945 and represents a very significant share (68.33%) of Liege building stock. In the Walloon region, the average heating energy consumption per year of the building stock is 408 kWh/m2 and the average heating energy consumption per year stands at 340 kWh/m2 for Liege. Hence, it is important to study existing buildings to improve the energy efficiency as well as thermal comfort standards. It is also important to understand the behaviour of these buildings and the preferred indoor thermal environment of the occupants. Keeping this in mind, the indoor thermal environment has been monitored for ten residential buildings followed by detailed interaction with the occupants to record their preference and expectations about indoor thermal comfort. It was found from the analysis that the fluctuations in the temperature of living room and bedroom with respect to outdoor conditions are a function of occupant’s age, type of heating system and fuel used. It is also found that the average energy expenditure was very high in these buildings. The study further identifies specific areas that need to be taken into consideration in order to improve the thermal comfort and energy efficiency. It put forth the argument that to improve the energy efficiency of occupied houses, occupant’s preference and expectations on thermal comfort needs to be considered for designing sustainable solutions towards improving energy efficiency.

The aim of this paper is to present a user-oriented protocol for the characterization of colour attributes in an urban fragment. The challenge is to provide quantitative answers to these questions: how is colour organized? How does it develop a structure in the city? Our research investigates stable colour typologies. The obvious lack of effective tools for the chromatic assessment in the field of urban design was the main motivation of this research. The protocol is illustrated within the study of the “rue des Anglais” in Liège (Belgium) and the stability of the method is conducted through a series of validations. [less ▲]

We report on results derived from investigations related with vicinal strategies on water management and their effects on the territorial configuration of Cochabamba (Bolivia) metropolitan area. These strategies and their effects are determined by several factors namely, water resources scarcity, accelerated urban growth, self-management legal possibilities and important levels of public investment in both municipal as well as metropolitan scales. The approach is done firstly by describing the features of the studied zone and the problematic of water in the region. Secondly, through the show and analysis of the different forms and strategies of water management, we pay special attention to their effects on the morphology of neighborhoods and the urban networks. The results show the generation of a different territorial ordering which, differing from the one usually adopted in the literature, seems to exhibit how certain types of networks create fragments instead of articulations.

Les zones d'activité économique constituent, en Wallonie, un des leviers majeurs à disposition du Gouvernement pour favoriser le développement économique. Leur implantation suscite toutefois de nombreux débats au sein des élus locaux. Ces débats sont notamment alimentés par la perception que ces zones génèrent des recettes fiscales très limitées pour les communes. Cette contribution propose une analyse et une mesure des facteurs qui influencent ces recettes et, par conséquent, les choix locaux en matière d'affectation de l'espace. [less ▲]

Chaque année, les inondations par débordement des rivières provoquent des dommages significatifs en Wallonie. L’ampleur de ceux-ci est liée à l’importance des crues elles-mêmes, mais aussi à l’occupation du sol des terrains inondés. Dans le contexte des changements climatiques, comment évolueront les débits des crues « extrêmes » ? Quelle pourrait être l’influence de l’évolution de l’occupation du sol sur les dommages ? La vallée de la Meuse a été choisie pour investiguer et concrétiser les réponses à ces questions. Les dommages liés à une crue centennale ont été calculés pour la situation actuelle ainsi que pour différentes situations potentielles en 2100, suivant un scénario d’évolution climatique et neuf scénarios d’urbanisation de la Wallonie. L'accent sera mis sur tant sur le développement de ces scénarios que sur les conclusions robustes tirées des résultats obtenus en termes d’influence relative du climat et de l’occupation du sol sur les dommages futurs.

Commuting to and from dense urban centres is often believed to be more energy efficient than commuting from more suburban areas. However, quantitative evidence is lacking. In this context, this paper investigates the interactions between the spatial structure of the territory and transport energy consumption for commuting. Based on empirical surveys carried out every 10 years in Belgium, a quantitative method was developed and applied to assess energy efficiency of home-to-work and home-to-school travels. Our main findings highlight that urban structure acts upon travel energy consumption for commuting and that major cities present low energy consumption. However, a local-scale approach is useful for refining these observations, and this approach highlights the existence of secondary suburban and rural cores that also are characterized by low transport energy consumption. In this respect, the distance from home to a destination is paramount, whereas the mode of transport used has a lower impact. The method is parameterised and reproducible in other territories.

L’article aborde la question de l’action publique visant à promouvoir le développement durable des quartiers urbains existants. En particulier, il envisage la pertinence de développer cette action à partir d’une réorientation de la « politique des quartiers », modalité de l’action publique héritée de la fin du XXème siècle. Les structures publiques de quartier mises en place dans le cadre de cette politique pourraient en effet jouer un rôle d’accélérateurs de la transition de ces quartiers. Elles ont le potentiel pour cela, notamment grâce au réseau social qu’elles développent au sein de la population locale, sans l’engagement de laquelle les pouvoirs publics peuvent bien peu de choses. L’article envisage ensuite la pertinence d’une généralisation de cette politique à tous les quartiers urbains, selon des intensités variables et en complémentarité avec les politiques urbaines plus stratégiques, afin d’assurer un développement équilibré de nos territoires.

A large amount of research in the past has focused on the relationships between the energy consumption for home-to-work travels and land-use patterns. However, little is known about children's mobility. This paper analyses the energy consumption, travel distances and modechoices for school commuting based on two decennial surveys in Belgium. The results highlight the following: (1) Mobility behaviours have evolved drastically over the past decades for school commuting, an evolution that cannot be entirely related to land-use variables. (2) The energy consumption for school commuting is strongly dependent upon the school level. (3) The links between land-use patterns and energy consumption for school commuting are different than those highlighted within the literature between urban forms and home-to-work commutes. The concentration of secondary schools and tertiary institutions in urban centres induces higher energy consumption rates, whereas the decentralisation of nursery and primary schools across the entire territory leads to very low local energy consumption and increased walking and cycling. These results provide a better understanding of school commuting within the European context and could guide future policies focused on transport energy consumption at the local scale. [less ▲]
