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:

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.
The AIVC -TightVent - venticool 2023 Conference: “Ventilation, IEQ and health in sustainable buildings” will be held during 4-5 October 2023 in Copenhagen, Denmark.
Abstract submission is still open. Authors should submit their abstracts by March 27, 2023.

This work is part of two French research projects “Durabilit'air1” (2016-2019) and “Durabilit'air2” (2021-2024), that aim at improving our knowledge on the variation of buildings envelope airtightness through onsite measurement and accelerated ageing in laboratory-controlled conditions.
During a past AIVC conference, a publication of the Durabilit’air1 project has presented and discussed an experimental protocol for characterizing assembly of products for buildings’ airtightness in laboratory controlled conditions.

This work is part of two French research projects “Durabilit'air1” (2016-2019) and “Durabilit'air2” (2021-2024), that aim at improving our knowledge on the variation of buildings envelope airtightness through onsite measurement and accelerated ageing in laboratory-controlled conditions.
The content presented in this paper is based on two publications in past AIVC conferences (Moujalled et al., 2019, 2018) and a research paper (Moujalled et al., 2021) about the mid-term and long-term changes in building airtightness through on-site measurements in low-energy houses.

This study sets out to investigate to what extent the air permeability of a building envelope of a dwelling remains constant over longer periods of time. This was evaluated by executing an air pressurisation test in 30 dwellings located in Belgium and comparing these results to the initial measurement results obtained shortly after the construction of the buildings. The time span between both measurements ranges from 293 days to 4045 days. On average, the air infiltration rate of the building envelope increased with 24%, i.e. an increase of 64 m³/h at a 50 Pa pressure difference.
