Purpose of the work
I have already talked about the issue of airtightness designs in Swiss standards at the Buildair Conference in 2015. What are the challenges we are facing two years later, regarding airtightness in Switzerland? And which of the issues in this context could be of interest for other countries?
- Change to ISO 9972: What does this look like in practice?
- Do we see a higher number of airtightness designs today? What is the development here?
- Does it make sense for the airtightness layer in an airtightness design to always follow the insulation layer? What happens then with objects with several measuring zones or fire compartments?
- How can we achieve mandatory elimination of leakages in party walls as faults?
- How do European standards differentiate between the terms “airtight” and “smoke-tight”?
- Is Switzerland planning to make BlowerDoor tests a requirement? How much testing is actually done? An overview of current and future developments in Switzerland.
