Share this Post:

Thursday 1 April 2021, 17:00-18:30 CET


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


  • April 1st, 2021 (17:00-18:30 CET): Building ventilation: How does it affect SARS-CoV-2 transmission? (Register now)
  • April 8th, 2021 (09:00-10:30 CET): IAQ and Ventilation Metrics (Register now)
  • April 13th, 2021 (17:00-18:30 CET): Big data, IAQ and ventilation (Register now)

This webinar will address the potential mitigating role of building ventilation in the spread of the COVID-19 pandemic.


The first part of the webinar will 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.


The second part of the webinar will 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 ( & the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (


The webinar is facilitated by INIVE (
