DIRECT AND INDIRECT USES OF URBAN FOREST RESOURCES: CASE IN NAGOYA CITY, JAPAN

Urban forest has an important role in a city. Also citizen utilizes urban forest resources directly and indirectly in many ways. In this study, the direct and indirect uses of forest resources were studied based on a simple multipoint on-site field survey ...

Improving local wind estimation for the automated control of blinds

Jean-Louis Scartezzini, Dasaraden Mauree, Laurent Deschamps, Ali Motamed

Blinds are usually installed on building façade to improve the visual and thermal comfort of the oc-cupants. They are now often linked to an automat-ed system that helps control the glare and decrease overheating. These automated systems are linked to a we ...

A visual model for mobility practices and learnings, Or why new visualizations allow us to consider the city as a paedagogical space

Alexandre André Robert Rigal

Visualizations of the city are necessary to lead to inquiries and for designing urban and transport policies because they are needed to synthesize information, to stimulate new hypotheses, and to evoke models. However, most of the contemporary visualizatio ...

A simple one-dimensional model for urban canopy flows

Fernando Porté Agel, Wai Chi Cheng

In urban canopy parameterizations, an urban canopy is usually modelled as a drag force on the flow, and the turbulent shear stress is parametrized by various methods. One of the most common methods to parametrize the turbulent shear stress in urban canopie ...

Large-eddy simulation of flow and scalar dispersion in rural-to-urban transition regions

Fernando Porté Agel, Wai Chi Cheng

Large-eddy simulations (LES) are performed to simulate the flow and scalar transport in rural-to-urban transition regions. The LES framework is first validated with wind-tunnel experimental data of scalar dispersion within and above a staggered array of cu ...

Mobile Sensor Networks for Air Quality Monitoring in Urban Settings

Adrian Arfire

With urban populations rapidly increasing and millions of deaths being attributed annually to air pollution, there is a critical need for a deeper understanding of urban air quality. The locality of urban emissions sources, and the specific topography of c ...

Sensitivity of calculated solar irradiation to the level of detail: insights from the simulation of four sample buildings in urban areas

Marilyne Andersen, Giuseppe Peronato, Stéphane Bonjour, Jérémie Stoeckli

The assessment of the solar potential in urban areas relies on a geometrical model that can be defined at different levels of detail (LOD). In this work we compare the solar irradiation simulated on the surfaces of four sample buildings, which were modeled ...

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 ...

Cadres de vie, modes de vie et mobilités de loisirs

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 ...

Large-eddy simulation of atmospheric boundary layer flow and passive scalar dispersion over idealized urban surfaces

Fernando Porté Agel, Wai Chi Cheng

Accurate prediction of atmospheric boundary layer (ABL) flow and its interaction with urban surfaces is critical for understanding the transport of momentum and scalars within and above cities. This, in turn, is essential for predicting the local climate a ...
