Natural ventilation is an alternative to create comfortable and healthy indoor conditions. This work presents the development of a methodology to evaluate the thermal comfort produced by indoor natural ventilation in hot climates. This methodology includes the definition of the Heat Balance Index, . It is based on models of the heat transfer of the human body to the surroundings. To estimate the comfort evaporation term a correlation between the Heat Balance Index (HBI) and the Predicted Mean Value (PMV) was made. The gives the comfort air velocity range, which is useful to calculate the well-ventilated percentage of an indoor space for an specific climate condition in hot climates. A numerical simulation of a cross ventilated building is used as an application example. The numerical simulation is solved by using Computational Fluid Dynamics and is validated with experimental results.
