The ongoing research aims to characterize the air infiltration rate in a specific set of urban multifamily residences in Brazil. The infiltration rate, which corresponds to the renewal of air through the building's envelope when all windows and doors are closed, is a fundamental aspect of the thermal performance of housing, especially in the context of climate change. The methodology involves the collection of experimental data and computational simulation. The tracer gas method will be used to determine the air infiltration rate in a selected sample of buildings. Subsequently, this infiltration rate will be simulated in the CONTAM program for the same residences, allowing the numerical model to be validated with experimental data through adjustments to the input data. This approach aims to achieve more accurate and comprehensive results regarding air infiltration rates in Brazilian buildings and their modeling in computational programs.
