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.

13th International BUILDAIR Symposium – Collection of presented abstracts

A new collection is now available on AIRBASE, including the BUILDAIR 2023 Symposium abstracts which were presented during June 2- 3, 2023 in Hannover, Germany.

The full collection can be found and is freely accessible here.

Lesson learnt and new protocol for the Durabilit'air project: laboratory measurements

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.   

Impact of implementation conditions on the durability

The content presented comes from the Technical Note (TN) 71 “Durability of building airtightness” published on Airbase, the AIVC bibliographic database.
