Abstract
The evidence of airborne transmission of Covid-19 through respiratory aerosols, and the experienced restrictions on commercial activity reinforce the necessity of a paradigm shift in the design of building ventilation systems for this new post-pandemic context. Therefore, this study has used a coupled multizone-CFD code developed by the National Institute of Standards and Technology (NIST) and an infection risk model on ventilation analysis for a small office application. The influence of different ventilation modes and air filtration efficiencies on infection risk was assessed. The code was validated by a high-quality benchmark, and the results demonstrate that the simulations reproduce the basic performance of the ventilation strategies that were selected. The purposes of this study are to assess the reduction of airborne infection risk of Covid-19 due to ventilation strategies and to present a framework that may contribute to the selection of rational solutions for the future challenges in this new post-pandemic era.
