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:

TN 71: Durability of building airtightness

Much progress has been made to improve the airtightness level of new buildings. Still, little is known about the durability of building airtightness, or the impact of degradation on airtightness. This report presents a comprehensive review of studies that deal with building airtightness durability. Regarding field measurement studies, the envelope airtightness seems to decrease during the first years after achievement and then stabilize. However, these variations are rarely explained. Key elements that may drive airtightness variations were identified.

TN 68: Residential Ventilation and Health

Exposures in homes constitute the major part of exposures to airborne pollutants experienced through the human lifetime. They can constitute from 60 to 95% of our total lifetime exposures, of which 30% occurs when we sleep.

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”.
