E-guerrilla 3D participation: Approach, implementation, and usability study

Jens Ingensand, Thibaud Nicolas Chassin

Typical urban participatory approaches engage citizens through lengthy sessions far from the area under transformation by an urban project. Several issues result from these settings of involvement including the mobilization of similar individuals, overwhel ...

A Simple Mixing-Length Model for Urban Canopy Flows

Fernando Porté Agel, Wai Chi Cheng

Urban canopy models (UCMs) developed based on Prandtl mixing-length theory provide a simple method for predicting urban flows. In the existing models, the Prandtl mixing length and the sectional drag coefficient of buildings are usually assumed to be unifo ...

Quantifying the impacts of urban morphology on modifying microclimate conditions in extreme weather conditions

Jean-Louis Scartezzini, Vahid Moussavi Nik, Kavan Javanroodi

It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particu ...

A digital workflow to quantify regenerative urban design in the context of a changing climate

Pietro Florio, Parag Rastogi, Emanuele Naboni

The regenerative approach to design goes beyond limiting the environmental impact of the built environment and towards the enrichment of the ecosystem, adaptation to climate change, and the improvement of human health. This concept is being applied to buil ...

Seismic displacement-demand and urban damage distribution: the impact of different methods on vulnerability assessment

Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

This paper addresses seismic vulnerability assessment at urban scale. Particularly, it focuses on the differences in damage distribution obtained from the application of several simplified methods for displacement demand determination. The results obtained ...

Evolution of urban scaling: Evidence from Brazil

Claudia Rebeca Binder Signer, João Vitor Meirelles de Miranda

During the last years, the new science of cities has been established as a fertile quantitative approach to systematically understand the urban phenomena. One of its main pillars is the proposition that urban systems display universal scaling behavior rega ...

Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention

Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt, Stefano Tugulu

Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river reaches. ...

Seismic vulnerability assessment at urban scale: state of the art and perspectives

Lorenzo Diana

Italian territory is particularly sensitive to seismic actions. The Amatrice earthquake on August 24th 2016 confirmed this aspect. Such an event, nothing but extraordinary, has been able to cause huge and tragic damages. The direct knowledge of building fe ...

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 ...

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

Marilyne Andersen, Emmanuel Rey, 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 ...

Concevoir à grande échelle : modèles d'interfaces de mobilité et stratégies de transformations urbaines

Mathieu Louis Pierre Mercuriali

Large-scale design - Mobility interface models and urban transformation strategies This research project is based on the hypothesis that the urban transformations generated by mobility interfaces constitute a key component of successful sustainable urban ...

Comparative multi-criteria assessment of urban renewal scenarios for existing neighborhoods

Emmanuel Rey, Maria Gracia Riera Perez

The growth of European cities in recent decades, mainly characterized by a decreasing density and a functional segregation, has tendentially increased mobility, soil consumption, urban sprawl, social disparities and infrastructural costs. Hence, most Europ ...

THE IMPACT OF OCCUPANTS’ BEHAVIOUR ON URBAN ENERGY DEMAND

Darren Robinson, Frédéric Haldi

Using extensive field survey data acquired over the past seven years at the Solar Energy and Building Physics Laboratory at EPFL in Switzerland, models of occupants’ presence, opening and closing of windows and the raising and lowering of blinds have been ...

Multiscale modelling of urban climate

Climate has a direct impact on cities' energy flows due to the space conditioning (heating, cooling) needs of the buildings accommodated. This impact may be reinforced due to climate change and to the (so called) urban heat island effect. The corresponding ...
