The novel coronavirus, SARS-CoV-2, has the potential to cause natural ventilation systems in hospital environments be rendered inadequate, not only for workers but also people who transit through these even a limited duration. Studies of fields geosciences and engineering, when combined with appropriate technologies, allow possibility reducing impacts SARS-CoV-2 virus environment, including those hospitals which are critical centers healthcare. In this work, we build parametric 3D models assess possible circulation system built care infected patients during COVID-19 pandemic. Building Information Modeling (BIM) was performed, generating utilizing Revit software Autodesk CFD 2021. evaluation considered dimensional analyses 0°, 45°, 90° 180°. analysis patterns on both internal external surfaces distribution windows relation displacement dynamics air were considered. results showed that area hospital, wind speed reached velocities up 2.1 m/s entering building open windows. contact furniture, value decreased 0.78 m/s. some isolation wards house COVID-19, areas should equipped negative room pressure, velocity null. Our study provides insights into contamination as well surrounding hospitals, encounter high pedestrian traffic cities worldwide.
