TN 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:

Ventilation, IEQ and health in sustainable buildings (Book of Proceedings)

The Book of Proceedings of the 43rd AIVC - 11th TightVent - 9th venticool Conference: "Ventilation, IEQ and health in sustainable buildings" held in Copenhagen, Denmark on 4-5 October 2023.

The Impact of Deep Energy Renovations on Indoor Air Quality and Ventilation in Irish Dwellings

Achieving energy-efficient dwellings has become a vital part of the global climate action plan to reduce energy usage and carbon emissions. Deep energy retrofits (DER) can help reduce residential energy use significantly. However, evidence on how DER impacts on indoor air quality (IAQ), and consequently, occupant health, is scarce. More in-depth analysis of IAQ data before and after energy retrofits is essential to understand the indoor environmental challenges of adopting energy efficiency measures.

Evaluating the Impact of Air Cleaning and Ventilation of Airborne Pathogens and Human Bio-effluents at Two Primary Schools in Belgium

The COVID-19 pandemic increased the awareness and importance of infectious pathogens as contaminant in the indoor air, especially for non-residential buildings with a high occupational density like schools. During the COVID-19 pandemic air cleaning is often proposed as mitigation strategy for infectious risk in these types of buildings. However, indoor air quality (IAQ) in general comprises of a large range of possible contaminants and factors that can equally impact the health, comfort and well-being of occupants.

Can the Wells-Riley model universally assess airborne pathogen infection risk?

Some airborne pathogens can infect susceptible people over long distances in buildings when they are transported in small respiratory particles suspended in the air. The pathogen concentration in air can be decreased using engineering controls, such as ventilation, filtration, or inactivation. To determine their effect, it is common to use the Wells-Riley model to estimate the probability that a susceptible person is infected and is a function of the dose of infectious pathogen received and a Poisson distribution.

Evaluating the impact of air cleaning on bioaerosols and other IAQ indicators in Belgian daycare facilities

The scientific community has been aware of the importance of indoor air quality (IAQ) for many decades, but the COVID-19 pandemic has brought a significantly higher level of attention from the general public and governmental entities to this theme. However, IAQ comprises hundreds of other parameters besides infectious pathogens, many of which can equally impact the health, comfort and well-being of occupants.

Applicability and sensitivity of the TAIL rating scheme using data from the French national school survey

The TAIL rating scheme for assessing the quality of Thermal, Acoustic, Indoor air, Luminous, and the overall environment was initially developed to assess indoor environmental quality (IEQ) in hotels and offices. To broaden the use of the TAIL rating scheme to other buildings, its applicability for schools was studied. Two additional parameters, i.e., reverberation time and nitrogen dioxide concentration, were included to account for the specificities of the building use and population.
