Impacts of global warming on energy use for heating and cooling with full rebound effects in Switzerland

Philippe Thalmann, Marc Vielle, Camille Gonseth

Global warming is expected to lower the energy demand for heating, which would contribute to a decline in CO2 emissions. This effect may be offset by energy needs for additional cooling and by the impacts of households that reinvest the money they save on ...

On the impact of the wind speed on the outdoor human comfort: a sensitivity analysis

Jean-Louis Scartezzini, Dasaraden Mauree, Silvia Coccolo, Emanuele Naboni

The energy demand of buildings and outdoor human comfort are key elements of a sustainable urban design. The wind speed has an enormous impact on thermal sensation, but the sensation itself is hard to quantify. The objective of this paper is to understand ...
