Start of the Pandemic Preparedness Program through Ventilation - Knowledge Gaps and application of the results

Ventilation and air cleaning of interior spaces are promising methods for the reduction of airborne pathogen spread and may reduce the number of (airborne) infections. With this in mind, and in response to the 2020-2022 COVID-19 pandemic, the Dutch Ministry of Health, Welfare and Sport (VWS), in collaboration with TNO have initiated this research program focusing on ventilation (P3VENTI) as part of the larger Pandemic Preparedness Program of VWS (300 million Euros, annually).

ASHRAE Indoor Carbon Dioxide Position Document: What’s Next?

ASHRAE’s 2022 publication of a new position document on indoor carbon dioxide (CO2) has been a significant contribution to ongoing discussions of how indoor CO2 can be used to understand ventilation and indoor air quality (IAQ). The position document clarifies what is known about the relationship between CO2 concentrations and ventilation rates, the effects of CO2 on building occupants, and how CO2 concentrations relate to airborne infectious disease transmission. While the position document is a key step to addressing ongoing debate and

AIRBODS: Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2

The Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2 (AIRBODS ) project aim is to deliver guidance on the ventilation operation and future design of non-domestic buildings and to quantify the risk of, and reduce the transmission of SARS-CoV-2 in buildings. It is doing this through experimentation, computer simulation and fieldwork supporting the guidance and tools.

Ventilation in Schools - A Review of State Policy Strategies

In January 2023, the Environmental Law Institute (ELI) with funding from the U.S. Environmental Protection Agency (EPA), released the report: "Ventilation in Schools: A Review of State Policy Strategies".

12 January 2023, Webinar – Sleeping Environment IAQ and Sleep Quality

Our bodies need good rest and sleep as part of regular recuperation to enable us to perform our normal activities in life.  Sleep is an integral part of human life and the importance and significance of good bedroom IAQ, indoor air pollution, ventilation as well as bedroom thermal environment during sleep cannot be emphasized more. Yet, there is a paucity of information in the scientific literature in this regard, especially pertaining to IAQ in sleeping environments and sleep quality.  Are our bedrooms adequately ventilated at all times to maintain good IAQ?


AIVC's Technical Note 70: 40 years to build tight and ventilate right: From infiltration to smart ventilation

We are happy to announce the release of AIVC's Technical note #70: 40 years to build tight and ventilate right: From infiltration to smart ventilation!

As the AIVC was created in 1979, the 40th anniversary of the AIVC was celebrated in October 2019 at the 40th AIVC conference in Ghent. In the context of this celebration, it was decided to publish 2 overview publications:


ASHRAE Position Document on Indoor Carbon Dioxide

In March 2022, ASHRAE released a position document discussing the role of indoor CO2 in the context of building ventilation and IAQ. The positions address the use of CO2 as a metric of IAQ and ventilation, the impacts of CO2 on building occupants, the measurement of CO2 concentrations, the use of CO2 to evaluate and control outdoor air ventilation, and the relationship of indoor CO2 to airborne infectious disease transmission.
