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:

Feedback from the AIVC/ASC 2024 Workshop in Singapore, “Ventilation, IEQ & Sustainability”

The AIVC 2024 workshop “Ventilation, IEQ & Sustainability" organised in collaboration with ASHRAE Singapore Chapter was held on 18-19 April 2024 in Singapore. Participation was possible in person and the event drew over 160 participants - researchers, engineers & architects and industry representatives. The programme included 21 presentations grouped into 3 sessions: “Optimising Indoor Air Quality for Climate Resilience”, “Reducing Carbon Footprints: The Role of Energy efficient Ventilation Technologies” & “Smart Building Automation for Climate-Adaptive Ventilation”.

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.
