Urban boundary-layer flows in complex terrain: Dynamic interactions during a hot and dry summer season in Phoenix, Arizona

Anthropogenic modification of natural landscapes to urban environments impacts land-atmosphere interactions in the boundary layer. Ample research has demonstrated the effect of such landscape transitions on development of the urban heat island (UHI), but c ...

Calibrating and validating the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) urban cooling model: case studies in France and the United States

Martí Bosch Padrós

Understanding the cooling service provided by vegetation in cities is important to inform urban policy and planning. However, the performance of decision-support tools estimating heat mitigation for urban greening strategies has not been evaluated systemat ...

Carbon flows at neighborhood scale Case study in Geneva, Switzerland

Sophie Lufkin, Ulrich Joseph Jacques Liman

In a context of political commitment targeting net zero in 2050, controlling carbon flows is an essential operational imperative. The LOCUS methodology (Low carbon urban strategy) makes it possible to establish an exhaustive vision of carbon flows at neigh ...

Planning urban proximities: An empirical analysis of how residential preferences conflict with the urban morphologies and residential practices

Vincent Kaufmann, Luca Giovanni Pattaroni, Marc-Edouard Baptiste Grégoire Schultheiss

Urban proximity planning is foreseen as a solution to foster a “sustainable” city, including economic viability, environmental soundness and social inclusivity. This paper focuses on the inclusivity aspects by questioning the adoption of urban proximities: ...

Economic valuation of temperature-related mortality attributed to urban heat islands in European cities

Gabriele Manoli

As the climate warms, increasing heat-related health risks are expected, and can be exacerbated by the urban heat island (UHI) effect. UHIs can also offer protection against cold weather, but a clear quantification of their impacts on human health across d ...

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 ...

Assessing the impact of urban heat islands on the risks and costs of temperature-related mortality

Gabriele Manoli

Ambient temperatures have an impact on human health, with unfavourably warm and cold conditions both associated with elevated mortality risk. By modulating the temperature in urban environments, urban heat islands (UHIs) can therefore both amplify the impa ...

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 ...

Enhanced intensification of hourly rainfall extremes due to urban warming in Phoenix, Arizona

Gabriele Manoli

The main cause of flash and pluvial floods in cities is short-duration extreme rainfall events. The built environment can either intensify or weaken extreme rainfall intensity depending on the urban fabric that controls the local environmental and climatic ...

Evaluation of 30 urban land surface models in the Urban-PLUMBER project: Phase 1 results

Gabriele Manoli, Matthias Roth

Accurately predicting weather and climate in cities is critical for safeguarding human health and strengthening urban resilience. Multimodel evaluations can lead to model improvements; however, there have been no major intercomparisons of urban-focussed la ...
