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.

Noticeably higher concentrations of gaseous pollutants were measured in bedrooms than living rooms, and in winter than summer, where p-values were found to be of a stringent significance (average p = 0.008). PM2.5 concentrations were found to be exceeding the WHO 24-h average threshold of 15 µg/m3 in kitchens for the week-long monitoring time (92% in winter, 51% in summer).

This article follows a first publication presented at the AIVC2022 conference (Handtschoewercker, 2022), with the preliminary results of the RENOVAIR project, that studies the impact of energy renovation works on social housing on the comfort and health of occupants when no requirements are given on IAQ, ventilation and airtightness performances.

The global demand to improve the energy performance of buildings has led to greater air tightness and uncertainty in the ability of natural ventilation to maintain adequate indoor environmental quality. A monitoring campaign was carried out to evaluate the long-term indoor environmental quality across a year-long period in energy-efficient Irish dwellings.

Controlling air infiltration is crucial to ensure thermal comfort, optimal performance of ventilation systems, and the overall energy efficiency of buildings. The quantification of the overall airtightness of the building envelope, often conducted through pressurization tests, has been widely used. In addition, IR thermography is a valuable complementary tool for identifying and locating air leakage paths.

Buildings energy renovation is a major priority in most European countries in order to achieve a fully decarbonized building stock by 2050. In France, 7 million homes are poorly insulated and 14% of French people feel cold in their homes. The government has thus implemented an ambitious plan to scale up energy-efficient renovations of buildings to achieve carbon neutrality by 2050 while also pursuing a social objective of combating energy precarity.

This study utilized a CONTAM simulation to assess the effects of airtightness improvements in TNPI rooms. Sobol sensitivity analysis was used to evaluate the impact of building envelope elements on pressure differentials and contaminant dispersion. Results showed that inter-room penetrations, ward doors, and ward ceilings significantly influenced differential pressure, while exterior walls and inter-room penetrations predominantly affected contaminant dispersion.
