Precisely predicting the future is an almost impossible challenge. However, predicting possible trend-lines is a more common thing. Current greenhouses gases emissions and climate change are among the most worrying issues humanity will face in a near futur ...
As humans spend most of their time indoors, indoor air quality (IAQ) significantly impacts their health. In parallel, building ventilation consumes significant energy, contributing to climate change. However, the relationships between the building ventilat ...
The urgency of reducing greenhouse gas emissions is greater now than ever, with the impacts of climate change becoming more apparent each year. Due to this, governments are setting ambitious targets such as reaching net zero GHG emissions by 2050, as annou ...
We prove the semi-global controllability and stabilization of the (1+1)−dimensional wave maps equation with spatial domain 𝕊1 and target Sk. First we show that damping stabilizes the system when the energy is strictly below the threshold 2π, where ha ...
In Part I of this paper, an inequality satisfied by the vacuum energy density of the universe was derived using an indirect and heuristic procedure. The derivation is based on a proposed thought experiment, according to which an electron is accelerated to ...
Why focus on action levers? • Wellbeing with low energy demand is clearly defined in low energy scenarios like LED or DLS, but it is far from obvious how to get there, including even collectively deciding on what is a good transition. • Progressively chang ...
We managed to construct two novel and functional methodologies to depict the evolution of energy efficiency improvements (EEI) in two Swiss sectors, housing and cement. This allowed us to obtain a better representation of EEI triggered by energy and climat ...

Climate induced extreme weather events and weather variations will affect both the demand of energy and the resilience of energy supply systems. The specific potential impact of extreme events on energy systems has been difficult to quantify due to the unp ...
We demonstrate the importance of addressing the F vertex and thus going beyond the GW approximation for achieving the energy levels of liquid water in manybody perturbation theory. In particular, we consider an effective vertex function in both the polariz ...
Biorefineries hold the potential to provide products and energy carriers at reduced environmental impact compared to their fossil-based counterparts. Thus, they can contribute to the decarbonization of sectors in which electrification of demands is challen ...
