Brazil is a country with a predominantly hot climate, therefore, methods of obtaining natural ventilation should be considered as a means of achieving thermal comfort in environments. This work aims to investigate natural ventilation and thermal comfort in building arrangements, using Computational Fluid Mechanics. For this, the OpenFOAM software will be used, using the standard k-epsilon turbulence model. A 3D model of a typical residential project from the Minha Casa, Minha Vida program was evaluated, inserted into a building arrangement, thus simulating a housing complex. The Elevated Air Speed Comfort Zone method (ASHRAE, 2017) was considered to determine whether or not thermal comfort occurred. The velocity, pressure and temperature fields were resolved, and it was possible to observe that some rooms experienced thermal discomfort caused by excessive wind speed, mainly in the windward house. The leeward houses presented most of the environments within the ideal thermal comfort ranges.
