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 together TightVent are organizing the webinar “Ensuring Reliable Airtightness Measurements: Airtightness Tester Qualification Across Countries” on 16 June 2026 (14:00 - 15:30 CEST). The webinar will present and compare these different approaches to the qualification of airtightness testers.
The event will feature presentations by:
Paul Carling – BCTA, UK
Laverne Dalgleish –ABAA, USA
Valérie Leprince – Cerema, France
Attendance is free of charge, but advance registration is required.
We are happy to share that the video recordings and presentation slides from our recent webinar, “Airtightness in Practice: Long-Term Performance, Field Evidence, and Innovative Detection Methods” (held on 17 March 2026), are now available on our website.
The webinar featured the following expert presentations:

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).
