Cool material

On the impact of innovative materials on outdoor thermal comfort of pedestrians in historical urban canyons

Urban heat island is an anthropogenic phenomenon affecting urban outdoor thermal comfort conditions
and energy utilization. This is even truer in urban canyon con?gurations, characterized by low sky view
factor and where the effect of short-wave and long-wave solar radiation on construction surfaces is able
to produce massive outdoor local overheating. Traditional solutions cannot always be applied in urban
historical canyons, where the exteriors of buildings cannot be modi?ed due to preservation. Here, the
