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 ...

Performance of lightweight and heavyweight building walls with naturally ventilated passive and active facades

Mohammad Rahiminejad, Dolaana Khovalyg

Well-designed ventilated air-spaces behind external claddings in the building envelope can potentially reduce thermal energy flow in the entire wall structure. In this study, the impact of the dynamic thermo-hydraulic behavior of the flow in the naturally ...

Mapping urban underground potential in Dakar, Senegal: From the analytic hierarchy process to self-organizing maps

Michael Robert Doyle

This article presents a mapping method that seeks to provide urban planning with a diagnostic overview of the underground resources of an urban area. Resource potentials (for buildable space, groundwater or geomaterial extraction and geothermal energy) ten ...

Spatio-Temporal Relationship between Land Cover and Land Surface Temperature in Urban Areas: A Case Study in Geneva and Paris

Jean-Louis Scartezzini, Dasaraden Mauree, Roberto Castello, Xu Ge

Currently, more than half of the world’s population lives in cities, which leads to major changes in land use and land surface temperature (LST). The associated urban heat island (UHI) effects have multiple impacts on energy consumption and human health. A ...

Impact of Escherichia colifrom stormwater drainage on recreational water quality: an integrated monitoring and modelling of urban catchment, pipes and lake

Frédéric Charles Soulignac

In recent years, recreational waterbodies are increasingly favoured in urban areas. In spite of the growing concerns for maintaining the required bathing water quality, the impacts of stormwater drainage are still poorly controlled. In this context, this s ...

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

Shanshan Hsieh, Arno Schlueter

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 ...

A solar-based sustainable urban design: The effects of city-scale street-canyon geometry on solar access in Geneva, Switzerland

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

Buildings commonly have the largest share in the energy demand of a country, but they also offer sites for the generation of solar energy. Here we develop a methodology to analyse the effects of street-canyon geometries on the solar access of street surfac ...

3D model discretization in assessing urban solar potential: the effect of grid spacing on predicted solar irradiation

Emmanuel Rey, Marilyne Andersen, Giuseppe Peronato

The increasing interest in solar energy production in urban areas requires an accurate simulation of solar irradiation on building surfaces, including vertical surfaces. However, solar potential analyses are usually conducted on 2.5D models, which are limi ...

Assessing visibility in multi-scale urban planning: A contribution to a method enhancing social acceptability of solar energy in cities

Christian Roecker, Jean-Louis Scartezzini, Josef Andreas Schuler, Maria Cristina Munari Probst, Pietro Florio

Urban areas are facing a growing deployment of solar photovoltaic and thermal technologies on building envelopes, both on roofs and on façades. An effective solar energy planning process considers social acceptance, in relation to the landscape alteration ...

A city-scale roof shape classification using machine learning for solar energy applications

Jean-Louis Scartezzini, Bérénice Guiboud, Andreas Bill, Nahid Mohajeri Pour Rayeni, Dan Assouline

Solar energy deployment through PV installations in urban areas depends strongly on the shape, size, and orientation of available roofs. Here we use a machine learning approach, Support Vector Machine (SVM) classification, to classify 10,085 building roofs ...
