The role of built environments in preventing contamination and reducing the spread of Covid-19 for future pandemics

‘The built environment contributes to the spread and contamination of the virus, as people spend more than 90% of their time indoors and even more during lockdown and community quarantine. During the current pandemic, healthy and asymptotic individuals are staying in their houses, and many people that are affected by the virus are now in hospitals and in healthcare facilities. These situations might affect the spread and contamination of the virus, as well as individuals’ interactions with each other.

‘To reduce the contamination and spread of the virus in the built environment that might affect healthy individuals – such as health care professionals, office workers – it is important to understand the steps that need to be taken and the policies to be implemented along with the theories underlying them. One of the approaches to be considered in designing effective fresh air supply and air extraction ventilation systems to minimize the concentration of suspended viruses. This is in addition to other essential procedures to understand the movement of viruses in the indoor air and its suspension/resuspension to and from surfaces.’
