Abstract

Urban growth has led to an increase in the construction of multi-family buildings, which has increased the demand for underground parking spaces. In this study, the ventilation system of these spaces was optimized using Computational Fluid Dynamics (CFD) simulation to reduce the carbon monoxide concentration. The mathematical modeling of air flow and carbon monoxide dispersion was based on Navier-Stokes equations, which allowed the evaluation of different ventilation configurations and improved air distribution. The results show that the optimization reduced the carbon monoxide evacuation time from 13.20 minutes to 7.00 minutes, increased the air velocity from 0.1 m/s to 1.5 m/s, and reduced energy consumption by 40%, ensuring compliance with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 62.1 standard. As a result, these results can be used to design and improve underground parking garage ventilation systems.
