Climatic and Economic Background Determine the Disparities in Urbanites’ Expressed Happiness during the Summer Heat

Gabriele Manoli

Climate-change-induced extreme weather events increase heat-related mortality and health risks for urbanites, which may also affect urbanites’ expressed happiness (EH) and well-being. However, the links among EH, climate, and socioeconomic factors remain u ...

Spatiotemporal patterns of urbanization during the last four decades in Switzerland and their impacts on urban heat islands

Martí Bosch Padrós

Urbanization is nowadays a global phenomenon which is increasingly concentrating the world's population in cities. In Switzerland, recent decades have seen an unprecedented loss of arable land due to urbanization, which has triggered amendments in the spat ...

Street grids for efficient district cooling systems in high-density cities

Shanshan Hsieh

The feasibility of district cooling systems is linked to their efficiency, which is associated with their capital and operational costs. For reasons of ownership and maintenance, the piping network commonly follows the city's street layout. This paper exam ...

Genèse et actualité d’une critique de la ville par les marges: Enquêtes en terrains bruxellois sur les possibilités de différer dans la ville contemporaine

Luca Giovanni Pattaroni

In this article, we address the persistence of urban critiques operated from the margins, that is, from what differs and struggles to find its place in the urban order. Those critiques, which historically emerged with urban struggles and artistic avant-gar ...

On the inefficiency of ride-sourcing services towards urban congestion

Nikolaos Geroliminis, Caio Vitor Beojone

The advent of shared-economy and smartphones made on-demand transportation services possible, which created additional opportunities, but also more complexity to urban mobility. Companies that offer these services are called Transportation Network Companie ...

Implementation of a sustainability monitoring tool into the dynamics of an urban brownfield regeneration project

Emmanuel Rey, Martine Laprise

Within the context of post-industrial European cities, the regeneration of urban brownfields contributes to limit urban sprawl by increasing cities density while revitalizing neighborhoods. Yet because of their complex nature, urban brownfields regeneratio ...

Socio-economic determinants of sprawl: causes and consequences of urban growth in Swiss municipalities

Barbara Franziska Weilenmann

In Switzerland, as elsewhere, over the past decades, urban areas have spread outwards â consuming the surrounding countryside in the process. The result has been an urban growth associated with negative effects such as the loss of cultivated land. Sprawl ...

Addressing Urban Sprawl from the Complexity Sciences

Jérôme Chenal, Stéphane Joost, Martí Bosch Padrós

Urban sprawl is nowadays a pervasive topic that is subject of a contentious debate among planners and researchers, who still fail to reach consensual solutions. This paper reviews controversies of the sprawl debate and argues that they owe to a failure of ...

Identifying carbon emission reduction potentials of BIPV in high-density cities in Southeast Asia

Shanshan Hsieh

We use life cycle analysis, urban building energy simulations and urban form generation to compare the operational carbon emissions of buildings with building-integrated photovoltaics (BIPV) in locations with different grid electricity mixes in Southeast A ...

Fifth generation district energy systems for low carbon cities

Raluca-Ancuta Suciu

The focus and challenge for energy engineering in the context of rapid climate change is summarised by the Europe 20-20-20 targets, committing to a reduction in energy consumption of 20%. The most logical approach to achieve these goals is to target the mo ...

Energy integration of CO2 networks and Power to Gas for emerging energy autonomous cities in Europe

François Maréchal, Luc Girardin, Raluca-Ancuta Suciu

The concept of urban CO2 networks has been developed to deploy heat pump based district heating and cooling systems in dense urban areas. The use of the CO2 phase change reduces the cost of the heat distribution while allowing to recover waste heat that is ...

L'événement proxémique : étude des relations de circulation entre piétons aux heures de pointe à Delhi, Los Angeles, Paris et Tokyo

Lucas François Tiphine

In a context of traffic networks saturation related to urbanisation acceleration, this research is aimed at contributing to the scientific debate on this issue by building a model to describe dynamic pedestriansâ physical distances regulation behaviours ...

Monitoring opérationnel pour l'intégration des enjeux de durabilité aux projets de régénération de friches urbaines

Martine Laprise

In a context where the territorial development stakeholders seek to limit urban sprawl, urban brownfields represent an important potential: their regeneration allows an increased density within the existing built fabric and a revitalization at the neighbor ...

Urbaniser les Alpes suisses : stratégies de densification des villes en altitude

Fiona Pia

Regional planning, especially in the Alps, is high on the current news agenda in Switzer- land, more so than ever before. The skiing boom has driven massive urbanisation in mountain areas, primarily in locations at altitudes of 1400m or higher. For several ...

Effects of urban compactness on solar energy potential

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni, Dan Assouline, Govinda Upadhyay

Compactness is a major urban form parameter that affects the accessibility of solar energy in the built environment. Here we explore the relation between various compactness indicators and solar potential in the 16 neighbourhoods (11,418 buildings) constit ...

Potentialities of the urban volume : mapping underground resource potential and deciphering spatial economies and configurations of multi-level urban spaces

Michael Robert Doyle

This dissertation looks at the urban volume, in its natural and artificial materiality, as a source of potential for future urbanization. Underground resourcesâ for buildable space, geomaterials, groundwater and geothermal energyâ tend to be addressed on ...

Rethinking the house form in poor areas : researching a pedagogical methodology to improve self-build housing in Angola by creating a culturally and ecologically sensitive expert system

Joana Rosa Ferreira Leite dos Santos Aleixo

Studying housing requires a multidisciplinary approach in order to come up with comprehensive solutions for physical, social and cultural needs. This thesis intends to bring those needs into the process of creating the house, by proposing a methodology to ...

Cadres de vie, modes de vie et mobilités de loisirs : les vertus de la ville compacte remises en cause?

Sébastien Munafò

This thesis aims to examine the causal mechanisms of living environments on leisure mobilities and verify whether their inclusion is actually able to challenge the compact city as a sustainable urban form. The research focuses on the Swiss case and in part ...

Expansion and densification of cities: linking urban form to urban ecology

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

Despite much research on the ecological impacts of urbanization, we still do not know what development patterns are most effective in supporting ecological function. In particular, it is as yet unclear if compact urban forms are ecologically more favourabl ...
