Zero-Energy” Building (ZEB) is arousing more and more interest internationally, both in policies aiming at a more sustainable built environment (such as the European Directive PEB that will require, for example, all new buildings to be “nearly Zero-Energy” Buildings (nZEB) by 2020) and in the scientific literature. Although Zero-Energy can be considered at different scales, this approach only adopts the perspective of the individual building and neglects phenomena linked to larger scales. Therefore, this paper aims at investigating the “Zero-Energy Neighbourhood” concept. It proposes a calculation method that takes into account three main topics: the energy consumption of buildings, the impact of the location on the energy consumption for daily mobility and the use of renewable energies. An application of this calculation method to two representative case studies (one urban neighbourhood and one suburban neighbourhood) is proposed. Main parameters that act upon the energy balance are highlighted and combined to propose concrete results to improve our built environment and move towards more sustainability. Hourly and monthly balances, the potential of “energy mutualisation” and smart grids are keys challenges that are of crucial importance in the scope of a Zero-Energy objective at the neighbourhood scale.

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 / reconstruction) to answer two main questions: "how to intervene in suburban areas?" and" where to intervene? ". These main results focused on energy efficiency are then studied in a larger framework to highlight the opportunities, limitations, constraints and feasibility of each strategy. Concrete prospects and guidelines for policy makers are finally proposed to operationalize a "sustainable suburban renewal". These findings show that, beyond the traditional polarization of the debates on energy efficiency of our built environment between the “compact city” and the “sprawled city”, a new pragmatic paradigm, focused on the transition of suburban areas by densification, can make suburban areas evolve towards more sustainability.

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 » et de la « ville diffuse », en offrant de véritables opportunités pour la transition durable des territoires périurbains existants. Ces résultats théoriques, et appréhendés du seul point de vue énergétique, sont ensuite recadrés dans un contexte plus large pour mettre en évidence les opportunités, les limitations, les contraintes et la faisabilité de ces scénarios.

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 du recyclage des quartiers périurbains existants sous l'angle énergétique. Deux leviers d’actions sont mobilisés à cet effet : la forme urbaine, qui est étudiée en complémentarité de l’échelle du bâtiment individuel, et la mobilité, car l’étalement urbain est entretenu et favorisé, en grande partie par la dépendance à la voiture individuelle. Deux indicateurs principaux (les besoins de chauffage de différents types de formes périurbaines et un indice de performance des déplacements) sont développés et discutés pour mettre en évidence les scénarios de renouvellement les plus adaptés et répondre à deux questions : « comment intervenir dans les quartiers périurbains existants ? » et « où intervenir ? ». Des pistes concrètes visant à l’opérationnalisation d’un « renouvellement périurbain » plus durable sont ensuite proposées. [less ▲]

The process of urban sprawl, which commonly describes physically expanding urban areas, is a major issue for sustainable development. Urban sprawl is known to represent a significant contribution to the overall energy consumption of a territory for energy needs in buildings and for transportation. In this context, the thesis focuses on the energy assessment of existing suburban neighborhoods. The assessment includes two parts: (1) a computational approach combining dynamic simulation tools and a database of building typologies to determine the energy consumed in heating and (2) an empirical approach to assess the energy consumed by transportation systems (home-to-work and home-to-school journeys). The links between the spatial structure of the territory and energy use for commuting are highlighted. Several renewal strategies are proposed to improve energy efficiency in existing suburban neighborhoods. There investigate the thermal retrofitting of existing neighborhoods, the built density and demolition/reconstruction processes together with the location of the neighborhoods. Urban structure acts upon travel energy consumption for commuting. A good mix between work, schools and dwellings at the local scale, which allows reduced travel distances, is a good strategy to reduce transport energy consumption, whereas means of transport used is only of little impact. Student travel behaviors are specific to the level of education and the type of neighborhood. Finally, the thesis discusses the practical implications of the research to operationalize a suburban renewal that articulates energy efficiency of buildings and neighborhoods but also energy efficiency of the urban structure.

The world is undergoing the largest wave of urban growth in history. In the actual context of growing interests in environmental issues, uban areas are known to present high potentialities in terms of energy reduction. However, existing models and regulation often adopt the perspective of the individual building as an autonomous entity, and neglect the importance of phenomena linked to larger scales, while decisions made at the neighbourhood and the city scales have important consequences on the performance of individual buildings, on the transport habits of the inhabitants and on the potential mutualisation of renewable energy production. This chapter examines strategies toward a sustainable energy transition in the built environment. The chapter summarizes and put into perspectives findings from numerous studies that have investigated parameters influencing energy consumption of the built environment including location, urban form, density, mix use, mobility patterns, buildings insulation, energy mix and inhabitants’ behaviours. This chapter contributes to the important area of understanding how to facilitate a sustainable transition in the built environment through urban and suburban renewal. [less ▲]

The occupants' behaviour has a great influence on the energy demand, management and consumption of a building. This paper investigates the influence of three parameters related to human behaviour through their modes of occupations (based on family size, management of the heating system and management of the heated area) on the housing heating loads of a standard dwelling in Belgium. Seven levels of insulation were tested: no insulation, two intermediate levels corresponding to 3 and 6 cm of insulation, the current standard for new buildings in Belgium, the low energy standard, the very low energy standard and the passive house standard. Multi-zone simulations were performed with a dynamic thermal simulation software. The impact of occupants' lifestyle and the interactions between occupation modes and insulation levels are highlighted. These results prove that the more the building is insulated, the more the lifestyle proportionally influences the heating loads. One important strategy for reducing heating consumption during the whole life cycle of the building is adapting the size of the house and its occupation modes to the evolution of family size. However, insulation is paramount, and increasing the insulation of the house provides generally better results than merely adapting the occupation mode. [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 ▲]
