Hospital dorm analysis: an approach to capacity systems

Abstract

Architecture can be understood as a continuous process of adaptation of uses and/or individuals, such adaptations commonly require expansions, these when not foreseen and/or considered, can make the use of spaces unfeasible. This is the case of the new coronavirus, SARS-CoV-2, which has the potential to make natural ventilation systems in hospital environments unsuitable, not only for workers, but also for people who pass through these environments, even for a period of time. limited. In this study, parametric 3D modeling was performed to analyze the possible circulation of the SARS-CoV-2 virus in the natural ventilation system of a hospital built to treat patients infected in the COVID-19 pandemic. The building was modeled in BIM, generating 3D models of the hospital environment using Revit software and later, for simulation purposes, the Autodesk CFD 2021 software. The evaluation considered dimensional analyzes of 0°, 45°, 90° and 180° . The analysis of natural ventilation patterns on the internal and external surfaces and the distribution of windows in relation to the dynamics of displacement of the SARS-CoV-2 virus through the air were considered. In these simulations, the wind speed reached speeds of up to 2.1 m/s when entering the building through the open windows, when in contact with the furniture the value changes to 0.78 m/s. This article provides insights into the possibility of SARS-CoV-2 contamination in indoor hospital environments.
