Arboreal specimens impact the buildings' courtyard landscape composition and interfere with their microclimate. The objective is to evaluate the thermohygrometric benefits that tree specimens implanted in internal courtyards bring to their surrounding environments, in the building. The investigation was conducted by computer simulation, modeling the courtyard with and without the presence of tree specimens, aiming to capture their influence on the courtyard and adjacent enclosures. There was a low quantitative impact of thermal cooling and air humidification inside the courtyard, near corridors, and adjacent rooms. However, spatially, the specimens provide thermohygrometric benefits to all surveyed environments, contributing as a complementary strategy to the ambiance of the building.
