1 April 2021, Webinar – Building ventilation: How does it affect SARS-CoV-2 transmission?
17:00 Europe/Brussels

The Air Infiltration and Ventilation Centre (AIVC) in collaboration with IEA EBC Annex 86 are organizing a spring workshop consisting of a series of three webinars on:

In this webinar, we address the potential mitigating role of building ventilation in the spread of the COVID-19 pandemic. In the first part of the webinar, we look at building ventilation as one of the mechanisms that affects exposure to infectious aerosol and the uncertainty in relating exposure to airborne transmission of the virus. In the second part of the webinar, we focus on the airflow in real indoor environments, with results from field experiments with aerosol sources and the use of pressure difference in buildings to control the spread of aerosols.

This webinar is organized by the Air Infiltration and Ventilation Centre (https://www.aivc.org/) & the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/). The webinar is facilitated by INIVE (http://www.inive.org/).
