Tree root distribution modelling in different environmental conditions

David Andrew Barry, Paolo Perona, Massimiliano Schwarz

The ability to predict the spatial distribution of tree root system variables (e.g., the Root system Area (RA), the maximum root diameter, the number of roots in diameter classes, the density of fine roots, etc.) under different environmental conditions is ...

A mechanistic assessment of urban heat island intensities and drivers across climates

Gabriele Manoli, Ziyan Zhang

The urban heat island effect (UHI) has been widely observed globally, causing climate, health, and energy impacts in cities. The UHI intensities have been found to largely depend on background climate and the properties of the urban fabric. Yet, a complete ...

Transmittance thresholds of electrochromic glazing to achieve annual low-glare work environments

Marilyne Andersen, Jan Wienold, Sneha Jain

A recent study on the glare protection performance of electrochromic (EC) glazing showed that visible transmittance levels lower than 0.6% are necessary to achieve comfortable situations for sun positions, that were close to the central field of view. Howe ...

A comparison of hydrological models with different level of complexity in Alpine regions in the context of climate change

Michael Lehning, Adrien Michel, Alice Marie Burri, Mathias Thierry Pierre Bavay, Francesca Carletti

This study compares the ability of two degree-day models (Poli-Hydro and a degree-day implementation of Alpine3D) and one full energy-balance melt model (Alpine3D) to predict the discharge on two partly glacierized Alpine catchments of different size and i ...

Spatial areas of genotype probability: Predicting the spatial distribution of adaptive genetic variants under future climatic conditions

Stéphane Joost, Oliver Michele Selmoni, Estelle Rochat

In a context of rapid global change, one of the key components for the survival of species is their genetic evolutionary potential for adaptation. Many methods have been developed to identify genetic variants underpinning adaptation to climate, but few too ...

Stabilization of cultural innovations depends on population density: Testing an epidemiological model of cultural evolution against a global dataset of rock art sites and climate-based estimates of ancient population densities

John Richard Walker, Taylor Howard Newton, Francesco Casalegno

Demographic models of human cultural evolution have high explanatory potential but weak empirical support. Here we use a global dataset of rock art sites and climate and genetics-based estimates of ancient population densities to test a new model based on ...

Solar energy potential at the Great St Bernard Pass

Josef Andreas Schuler, Pietro Florio, David Notzon

The historical site of the Great St Bernard Pass, situated in the Alps at an elevation of 2469 m, records very high electricity consumptions. This study aims at evaluating the photovoltaic potential at the pass. The analysis was performed on the envelope s ...

Large-scale regionalised LCA shows that plant-based fat spreads have a lower climate, land occupation and water scarcity impact than dairy butter

Xun Liao

Purpose In light of the sustainable diet debate, we conducted a large-scale regionalised LCA to answer the following questions: (i) does the climate advantage hypothesis of plant-based fat spreads and creams over dairy butter and cream hold regardless of t ...

Modern Schools in Angola, 1961-1975: Design with Climate and Heritage

Maria Margarida Gonçalves Quintã

The architectural production of Angola between 1961 and 1975 forms the basis of the current study. Taking into consideration that buildings' environmental performance is, at one time, one of the most central aspects of the Modern Movement legacy and a pres ...

Concerns of young protesters are justified

Philippe Thalmann, Dominique Bourg

In this letter, we recall that young people's concerns about climate change are based on our best scientific knowledge and that the measures taken so far by our authorities to protect the climate and the biosphere are far from up to the threat. We therefor ...

Welfare effects of technology-based climate policies in liberalized electricity markets: seeing beyond total system cost

Philippe Thalmann, Frank Vöhringer, Sophie Maire

This paper is a contribution to assessing the Swiss energy transition, with an emphasis on the consequences of decommissioning the nuclear power plants for the electricity market and the whole economy. We expect that increased renewable generation and dema ...

Responses of permanent grasslands to drought during the plant growing season: combining agronomic, functional and ecophysiological approaches

Amarante Vitra

Extreme summer drought events are predicted to increase in intensity and frequency within the current century. The resulting water scarcity could dramatically impact human activities related to agriculture, due to the strong relationship between precipitat ...

Different approaches to improve energy consumption of battery electric buses

Francesco Baldi

Transportation electrification is increasing and recently more focus has been directed on heavy vehicles and especially on city buses. Battery electric buses are inherently more energy efficient than diesel buses and the efficiency can be further increased ...

Reliability of photovoltaic modules : from indoor testing to long-term performance prediction

Eleonora Annigoni

A fundamental challenge with solar energy is improving the reliability, and increasing the lifetime, of photovoltaic modules. Typically, photovoltaic module manufacturers guarantee 80% of the nominal power of their modules for 25 years, but this type of gu ...

Risk perception and decision-making: do farmers consider risks from climate change?

Claudia Rebeca Binder Signer

Small-scale farmers are highly threatened by climate change. Experts often base their interventions to support farmers to adapt to climate change on their own perception of farmers' livelihood risks. However, if differences in risk perception between farme ...

Thermal Comfort Maps to estimate the impact of urban greening on the outdoor human comfort

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Silvia Coccolo

Outdoor human comfort is an important factor in the evaluation of the liveability of a city as well as for promoting people’s health and well-being. In hot arid climates in particular, urban planning and design can considerably impact the day-to-day therma ...
