In the study of urban canyons, field data collection provides valuable information, but does not always allow the comprehension of more complex physical processes of surface interaction with the environment. On the other hand, simulation methods, despite being a simplification process, offer an alternative analysis for these phenomena. So, the aim of this study is to propose the construction of a physical model of an urban canyon in a tropical context in order to observe the microclimatic variables associated with four varieties of pavements. Characterization of the area and implantation site comprised the initial phase of the method. Next, the strengths and weaknesses of the simulation models were discussed. The results demonstrated that physical scale models have the potential to observe a variety of physical phenomena that occur in urban canyons, particularly surface temperature and winds. However, the limitations associated with the inertia of the materials, make physical scaled model unsuitable for energy balance investigations. Thus, the potential for mitigation measures and the consequences of public climate adaptation policies at the local level can be observed with greater precision, thereby facilitating the construction of climate-responsive structures in the real world.
