Abstract
The adaptation of public spaces to episodes of intense heat is now a major
challenge for cities. With this in mind, this article presents a contribution aimed at
delineating and handling the shadows on the ground or in a horizontal plane at a given
height, whether it comes from buildings, street furniture or the tree cover. After a comparison
with shadows obtained via two reference tools, we present two urban sites that mix shadows
of different origins and, in addition, different indicators. The results of the simulations are
compared with pyranometric surveys carried out on site. The aim of these indicators is to
assist urban designers with solutions that make it possible to distinguish the respective
shadow contributions, their annual evolution and potential spatial or temporal continuities.
