an investigation into energy and cost of strategies that can mitigate risk of covid-19 transmission

In order to systematically reduce the risk of sars-cov-2 infection in the indoor space, it is important to understand the building design strategies and air quality enhancement methods that are set to mitigate this threat. as the universities are resuming their pre-covid in-person curriculums, this paper aims to introduce the different hvac technologies used to mitigate the spread of covid-19 in the university classrooms, in particular. many of these technologies came to be as an outcome of the scientific interest in the enhancement of indoor environmental quality. thus, it is important to understand where airborne pathogens fit in the overall scheme of indoor air health. similarly, this paper sets to reimagine the architectural methods as the solutions to the problem of airborne transmission of diseases. based on the urgency of the problem and the demand of the market, in this work, we discuss a summary of applicable technologies and strategies to combat airborne viruses, particularly covid-19, in the ventilation systems and enclosed spaces. by presenting an overview of the problem and the solutions that integrate engineering controls, the design strategies and indoor air sanitization techniques aim to create healthier indoor environments. this paper aspires to move the research forward.
