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 ▲]

La question de la verticalité est récemment revenue parmi les préoccupations et débats d'experts de la ville. Les tours continuent de faire l'objet de controverses mais la volonté de les utiliser comme outil de développement urbain durable demeure. En France, le processus décisionnel de la construction des tours est linéaire et prend en considération relativement tard, les critères nécessaires à une bonne qualité d'insertion urbaine. L'article propose une méthode d'implantation de tours plus globale, permettant d'évaluer l'insertion urbaine d'une tour par rapport à son environnement ainsi que d'accompagner les acteurs impliqués dans leur prise de décision.

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.

The goal of this study is to identify those factors that trigger carpoolers to share their rides and the barriers that restrain non-carpoolers from doing so. To this end, four focus group sessions were organized. In addition, information from the 2009-2010 Flemish household travel survey was analysed. From the focus group discussions, it can be concluded that the concept of carpooling is generally well known, but that the media attention and stimuli for the topic seem to have faded away over time. The main motivations to carpool are the social aspect, the financial benefit or a combination of both. The quantitative analysis underlined for the difference between the distinct types of employees. Furthermore, the finding that the home-work distance increases the likelihood to carpool emphasizes the importance of the financial benefits of carpooling. Financial stimuli are thought to have the most potential to increase the share of carpooling in the modal split. [less ▲]

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 ▲]

Cette contribution a pour objectif de mettre au centre de la réflexion sur les inégalités environnementales les qualités intrinsèques du logement (superficie, type de chauffage, salubrité, etc.). L’accès à un logement de qualité reste en Wallonie un important vecteur de différenciation sociale. Nous proposons de considérer les attributs du logement comme une variable environnementale susceptible de renforcer les inégalités socio-économiques, au même titre que l’exposition au bruit, à la pollution atmosphérique ou l’accès aux aménités urbaines. A partir d’un indice de précarité socio-économique des quartiers, nous analysons les facteurs de renforcement des inégalités sociales et environnementales par la qualité du logement. L’étude de deux aménités urbaines - l’accessibilité par les alternatives à la voiture et l’accès aux espaces verts – permet de compléter cette approche. Nous mettons ainsi en exergue les spécificités des territoires urbains wallons – notamment au travers de l’analyse du cas spécifique de la région urbaine de Liège – et analysons comment ces aménités renforcent, compensent ou sont déconnectés – des inégalités sociales et en matière de logement.
