(numbered VIP 45.XX), detailing for both building and ductwork airtightness:

• the national requirements and drivers (regulations, incentives, justifications and sanctions)
• whether it is taken into account in the energy performance calculations and how;
• the test protocol (testers qualifications, national guidelines, requirements on measuring devices);
• the tests already performed and whether there is a results database;
• key documents.

This presentation focuses on the airtightness trends in the Netherlands.

This article provides a summary of a comprehensive examination of the current ISO 9972 standard, focusing on the enhancements needed to improve its reliability and validity for airtightness tests in buildings. A working group composed of international experts has identified a list of issues warranting a potential revision of the standard. New recommendations are proposed based on research and consultation, including detailed considerations of previous guidelines and existing scientific literature.
