Upcoming Webinar “Airtightness tests for high-rise buildings” – 26 January 2024 [10:00-11:30 CET]
Building airtightness tests are now required or promoted in more and more countries, in particular for residential buildings. However, airtightness tests in high-rise buildings remain particularly challenging and uncommon. In addition to the difficulties of pressurizing any large-volume building and the wind issue that can be more pronounced at height, the stack effect can be particularly problematic. A temperature difference between inside and outside creates indeed significant pressure differences along the building’s envelope, with leakages not equally considered depending on their location, and therefore, test results that can vary depending on the test conditions.
The new Ventilation Information Paper n°47 published by the AIVC, discusses reasons behind specific problems with airtightness tests in high-rise buildings and proposes a method to tackle those issues.
The main objectives of this webinar are to:
- further explain the issue when testing high-rise buildings
- give practical recommendations to minimize the error due to the stack effect
- present alternative criteria to test high-rise buildings when those in standard ISO 9972 cannot be met
- give some on-site experience feedback
This webinar is organised with the support of TightVent Europe and AIVC. Both initiatives are facilitated by INIVE.
