This article has two aims. Firstly, to introduce the important environmental inequality scholarship, mostly imported from the USA, in the Belgian context, where few studies have been carried out to date on this topic. Secondly, to propose an unconventional approach to environmental inequality scholarship by focusing on housing conditions as substantial environmental inequalities. On this latter premise, we based this study on the CEHD housing quality survey carried out in 2012 and 2013 in Wallonia, to test several hypotheses as regards the relationships between housing quality, poverty, and spatial differentiation – discrepancies among population and space. The results confirm most of our research hypotheses, showing important inequalities in terms of housing conditions between wealthy and poor populations, as well as between urban areas, on the one hand, and suburban and rural areas, on the other. Our findings call for new avenues and priorities for housing policies in Wallonia, and for further research on housing quality as environmental inequality: with a focus on a specific target public – single households, and on subjective perception of environmental nuisances in and surrounding home.

Several studies were made to assess the direct damage but few studies tackled the topic related to the assessment of indirect damage. This paper discusses the development of a large scale agent-based micro-simulation framework to assess the economic damage caused by river floods. The advantage of this approach is that the economic loss can be assessed at individual level. For that purpose, relationship is established between costs and trips cancelation/duration growth. As the numerical simulations depend largely on the initial demand, the accuracy of the data is fundamental. The model is based upon several disaggregated data related to mobility behaviour of the Belgian citizens. The study area covers the Brussels metropolitan area which was subjected to several floods in the past and may see the risk increasing in the coming decades. [less ▲]

Thermal comfort study provides crucial information about thermal performance of naturally ventilated buildings. Humphreys and Auliciems comfort model uses indoor and outdoor temperatures to predict comfort temperatures. It is found that the comfort temperatures obtained by using these methods do not take into account the occupant behavioral adaptability to a particular climatic zone. This demands development of new set of comfort models based on local environmental parameters, socio-cultural setup and behavioral action. Analysis shows that four major variables like indoor and outdoor temperature, relative humidity and clothing pattern plays an important role in defining comfort and greatly influence the occupant’s perception and acceptance on thermal comfort. In this study, comfort models are developed based on these variables. The computed neutral temperatures based on the models are compared with the comfort temperatures obtained through comfort survey. The models are developed using the measured data of January and July months and validated with the measured data of April and October months. This study also concludes that it is not possible to obtain a generalized thermal comfort model for all climatic zone because adaptation process, expectation and perception of people are region specific and governed by local socio-cultural requirement.

The goal of the project FloodLand is to investigate the complex interactions between landuse change and future flood risk. Landuse change is assumed to be mainly driven by population growth and socio-economic factors. It affects future flood risk by altering catchment hydrology as well as vulnerability in the floodplains; but the feedback effect of (the perception of) changes in flood hazard on landuse evolution is also considered. The research is based on a chain of modelling tools, which represent parts of the natural and human systems, including: landuse change modelling, transportation modelling as an onset for the estimation of indirect flood damage, continuous hydrological modelling (forced by precipitation and temperature data disturbed according to climate change scenarios), as well as efficient hydraulic modelling of inundation flow in the floodplains. Besides reproducing a broad spectrum of processes, the modelling approach spans over multiple scales, from the regional or catchment level down to the floodplain and building levels. This distinctive feature is reflected both within the individual models and through their combination involving fine-scale detailed analyses (or data) embedded within coarser models at a broader level.

In market-oriented economies, high rates of homeowners are traditionally associated with positive economic effects and externalities. For this reason, public authorities have encouraged homeownership for the last decades through taxation or subsidies policies. In Belgium, owner-occupation has been promoted since the end of the nineteenth century and homeownership policy is considered as a key element of the Welfare state. Furthermore, the effectiveness of these policies is fundamentally based on a clear understanding of what determines homeownership. Therefore, the analysis of tenure determinants can provide inputs for the definition or the renewal of housing, taxation and subsidies policies. Considering this interest, this paper investigates the issue of housing tenure in Belgium. On the basis of previous related research, a model of tenure choice is estimated using a sample of 6,962 households. The observations follow clearly the general trends described for other countries. Higher income and age, couple status and the presence of dependent children have positive influences on homeownership. In addition, locations presenting a high density of population and a high centrality are associated with a lower probability of homeownership compared with other areas. The underlying significations of these variables are discussed in the paper. [less ▲]

In market economies, homeownership is associated with positive ex- ternalities. Increasing the levels of homeownership has been an objective of governments for the last decades. The analysis of the determinants of tenure sta- tus provides information to this end. This paper proposes an econometric analysis of housing tenure in Belgium. We review the main variables that have been considered in the literature as influencing housing tenure, after what we estimate a logit model. We observe a strong influence of income and age on the probability of homeownership. Couple relationship and the presence of dependent children have a positive influence, but this influence is less significant. Urban location is associated with lower probability of homeownership, compared with other areas. Our observations follow the trends described for other countries in the literature. [less ▲]

In contemporary fragmented cities, DIY urbanism is seen as a way to insure inclusiveness and cohesion by mobilizing citizens and improving urban space. However, the capacity of DIY to go beyond local epiphenomena and contribute to a systemized way of city making is still an open question that is gaining increasing interest in literature and practice. In this article, we differ from answers provided in the literature to this question in that we are interested in the ways DIY practices could contribute to build from the bottom-up large-scale territories. We rely on Lévy-Strauss oppositions of the bricoleur vs. the engineer and the “savage” vs. the scientist to stress that DIY is instrumental and political. This leads us to consider DIY as a process of problem-solving and domos building where the operational and socio-spatial aspects of DIY are intrinsically linked and evolving together. It is by understanding both these aspects that we can understand the possibilities of, and limitations facing, the development of DIY on a larger territorial scale. We build on case studies in Cochabamba, Bolivia and Beirut, Lebanon. We argue that though it is possible to succeed to build on DIY to develop local territories and rely on these experiences to trace larger ones, the operational and political modes would invariably move towards more top-down comprehensive engineer-like approaches.

Solar simulation and evaluation tools are essential for the design of novel energy and environmental strategies. To date, a number published studies in this area focused on the analysis of flat roofs and small urban areas. This paper presents a method, based on Geographic Information Systems (GIS), for defining the potential of photovoltaic solar energy over urban faßcades. The method enables the generation of 3D solar maps from two standard data sources, namely cadastral cartography and data on solar irradiance registered by the Spanish State Meteorological Agency (AEMET, for its initials in Spanish). A series of charts have been generated relating the urban and solar geometries as a result of the numerical model. The charts permit the study of the optimal parameters for the photovoltaic integration over faßcades. In addition, a study conducted over a representative urban area of Madrid is discussed as an example of the applicability of the discussed methodology. Finally, the adequacy of the Spanish Technical Edification Code (CTE, for its initials in Spanish), defining thresholds regarding the usability of photovoltaic energy, has been tested both theoretically and through the case study. Our study concludes that this regulation hinders the architectural integration of photovoltaic devices given the strict usability thresholds adopted. [less ▲]

Après une phase d’expérimentation et de maturation, l’application des principes de durabilité aux projets de nouveaux quartiers est aujourd’hui entrée dans une phase de généralisation et de normalisation. Le concept de « quartiers durables » s’est démocratisé et fait l’objet d’une popularité grandissante. On ne peut a priori que s’en réjouir, pour autant que cette diffusion réponde à une véritable affirmation des principes clés du développement durable à l’échelle des quartiers et qu’elle s’inscrive dans une logique territoriale à plus grande échelle. C’est dans cette optique qu’a été développé le référentiel quartiers durables, élaboré par le Centre de Recherches sur la Ville, le Territoire et le Milieu Rural (Lepur) de l’Université de Liège (Belgique), à la demande du Ministre wallon de l’Environnement, de l’Aménagement du Territoire et de la Mobilité. Ce référentiel constitue un cadre général visant à inciter et favoriser l’émergence d’opérations innovantes en matière de quartiers durables et s’inscrit dans le cadre de la Déclaration de Politique Régionale par laquelle le Gouvernement wallon s’est engagé à soutenir des opérations innovantes en la matière. Ce référentiel opérationnalise le concept de « quartier durable » en objectivant les critères minimum à respecter pour prétendre à cette appellation, considérant que, si tous les quartiers n’ont pas pour vocation d’entrer dans cette démarche, intégrer des critères transversaux de durabilité dans le plus grand nombre possible d’opérations d’urbanisme est un enjeu sociétal majeur. Concrètement, le référentiel quartiers durables s’articule autour de 5 thématiques (les potentialités du site et du projet, les ressources, les milieux naturels, les aménagements, la mixité et la participation) et de 25 critères qui couvrent les critères minimum à respecter pour inscrire un projet dans une vision transversale de développement durable. Une valeur-seuil est attribuée à chaque critère et modulée selon les potentialités du site. L’ensemble des critères sont expliqués dans un langage simple et complétés d’exemples de bonnes pratiques, de photos et de schémas explicatifs de façon à faciliter l’appropriation du référentiel par tous les acteurs de l’aménagement du territoire et à favoriser le développement des projets de quartiers réellement durables. Cet outil d’aide à l’élaboration et à l’évaluation des projets de quartiers durables est destiné aux administrations communales et régionales, aux promoteurs et aux auteurs de projet. Il peut s’appliquer à différents types de procédures urbanistiques (permis d’urbanisation, permis groupés, plans communaux d’aménagement, rapport urbanistiques et environnementaux) comme lors de concours ou d’appels à projets. Le référentiel quartiers durables a été appliqué, dans une première phase, à douze projets existants de quartiers durables (terminés ou en cours de production) afin de tester son applicabilité et d’ajuster les valeurs-seuils proposées. Le référentiel a ensuite été mobilisé dans le cadre d’une opération-pilote d’aménagement d’un quartier durable (dialogue compétitif pour la réalisation d’un nouveau quartier durable sur le site de la Sucrerie à Genappe, 291 logements, 8 hectares, 62 millions d’investissement). Validé politiquement et distribué largement (2.500 exemplaires) aux acteurs locaux de l’aménagement du territoire et de la production de quartiers durables, le référentiel quartier durable est actuellement utilisé par les acteurs locaux dans de nombreuses opérations en cours de développement. Notre contribution présentera d’abord le référentiel quartier durable et le contexte dans lequel il a été développé. Elle abordera ensuite l’application du référentiel à douze études de cas, puis un retour d’expérience sur l’opération-pilote en cours de développement à Genappe. Enfin, l’appropriation rapide du référentiel par les acteurs de l’aménagement du territoire, la reproductibilité du référentiel dans d’autres contextes et les perspectives ouvertes par ce nouvel outil d’aménagement durable concluront notre contribution.

This paper presents a practical handbook that aims at helping local authorities and private developers to build and assess “sustainable neighbourhoods” in Wallonia (Belgium). This handbook was developed by the Research Centre on Territorial, Urban and Rural Sciences (Lepur, University of Liège), at the request of the Walloon Minister of the Environment, Spatial Planning and Mobility. The concrete aim of the handbook is to concretely define the concept of "sustainable neighbourhood" by clearly tagging the minimum criteria that a real estate project must meet to obtain the “sustainable neighbourhood” label in Wallonia. It is a tool for decision support in the design as well as the evaluation of real estate projects, since the early stages of their design. The handbook is structured into 5 main theme and 25 criteria of sustainability. In a broad vision of sustainability, this handbook is not strictly limited to energy issues but considers "sustainability" in all its multiple components: location, network connection, mobility of inhabitants, use of natural resources, landscaping, waste management, diversity of function, social interactions, among others. The handbook is firstly presented and, then, applied to 12 recent case studies in order to identify common invariants in the design process of “sustainable neighbourhoods” and barriers to the integration of cross-cutting principles of sustainability in neighbourhood projects. Our main results namely show that the criteria dealing with energy performance of buildings and green spaces have percolated in many cases. However, the diversity of housing types, the accessibility to handicapped peoples, social diversity and participation issues remain poorly addressed in most of the cases studies. [less ▲]

Indoor thermal environment monitoring has been done in 20 residential buildings of Liege city followed by questionnaire based comfort survey amongst the occu- pants of 85 houses in order to record their preference and expectations about in- door thermal environment in winter and spring season. It is found from the anal- ysis 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 lead- ing to higher indoor temperature fluctuation and causes discomfort. It is also im- portant that the occupant’s preference and expectations as well as overall as- sessment of indoor environment needs to be consider towards energy efficiency improvement. [less ▲]

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 ▲]

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 ▲]
