Health-based target ventilation rates and design method for reducing exposure to airborne respiratory infectious diseases

Description

‘No method is available to design building ventilation and other measures to protect occupants against respiratory disease transmission. The current design of ventilation according to existing indoor climate standards EN 16798-1:2019 and ISO 17772-1:2017 has been limited to the use of ventilation criteria based on the perceived air quality (odours) depending on emissions from humans and a building and on specific pollutant concentration control. This approach neglects respiratory disease transmission for which the key engineering measure is ventilation, supported if necessary with air filtration and air disinfection’.

The Nordic Ventilation Group has published a proposal for post-COVID target ventilation rates on Scanvac webpage. The document is called “Health-based target ventilation rates and design method for reducing exposure to airborne respiratory infectious diseases”. The document has been reviewed by REHVA Technology and Research Committee COVID-19 Task Force and published also on REHVA webpage with an other layout.
