Webinar – Durability of building airtightness- assessment through field measurements

Share this Post:

Mandatory or voluntary building airtightness testing has come gradually into force in many European countries mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings. Therefore, airtightness levels of new buildings have significantly improved in the last decade. However, rather limited expertise is available as regards the durability of building airtightness at mid- and long-term scales.

The objective of this webinar is to share information on the durability of building airtightness evaluated through field measurements. Information provided will help the participants understand how building airtightness changes over time and improve the protocol for future field measurement campaigns.


This webinar is organised with the support of TightVent Europe ( and AIVC ( Both initiatives are facilitated by INIVE (
