Vegetation effects on climate and building energy demand in cities

Jian Wang, Gabriele Manoli, Paolo Burlando

Excessive heat in cities exacerbated by urban heat islands can negatively impact human health, building energy consumption, and urban ecosystems. Increasing urban greenery has often been proposed as an attractive mitigation strategy as vegetation can reduc ...

Réseau de distribution de chaleur et de froid utilisant le CO2 comme fluide caloporteur

Luc Girardin, Jessen Page, Alberto Mian, Samuel Henchoz, Patrick Chatelan, Cédric Dorsaz

Anergy networks with water circulation are an efficient solution for the supply of urban heating services, but require a bulky and expensive infrastructure with higher energy consumption. Replacing water with CO2 enables a more compact solution with lower ...

Canopy dieback and recovery in Australian native forests following extreme drought

Alice Jacqueline Frédérique Gauthey

In 2019, south-eastern Australia experienced its driest and hottest year on record, resulting in massive canopy dieback events in eucalypt dominated forests. A subsequent period of high precipitation in 2020 provided a rare opportunity to quantify the impa ...

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 ...

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 ...

Urban Forests as Main Regulator of the Evaporative Cooling Effect in Cities

Gabriele Manoli

Higher temperatures in urban areas expose a large fraction of the human population to potentially dangerous heat stress. Green spaces are promoted worldwide as local and city-scale cooling strategies but the amount, type, and functioning of vegetation in c ...

The question of housing at the center of urban health inequities

Jérôme Chenal, Vitor Pessoa Colombo, Akuto Akpedze Konou

If environmental factors are important determinants of health, then universal access to adequate housing is key to tackle urban health inequities. Yet, with over one billion urban dwellers having no other choice than living in so-called slums, the provisio ...

Tree effects on urban microclimate: Diurnal, seasonal, and climatic temperature differences explained by separating radiation, evapotranspiration, and roughness effects

Gabriele Manoli, Matthias Roth, Paolo Burlando

Increasing urban tree cover is an often proposed mitigation strategy against urban heat as trees are expected to cool cities through evapotranspiration and shade provision. However, trees also modify wind flow and urban aerodynamic roughness, which can pot ...
