TightVent Webinar | Ductwork airtightness measurements: protocols

Share this Post:

Various studies have shown that ductwork leakage has a major impact on energy use (i.e. increased fan energy use, heating & cooling losses etc.). However, in most European countries, it is not common to perform ductwork airtightness tests, which is probably due to the lack of awareness on the consequences of ductwork leakage. As follows, ductwork airtightness is not properly taken into account in most Energy Performance Regulations and Calculations.


The protocol to perform ductwork airtightness tests is also an issue for stakeholders who want to promote ductwork airtightness in a regulatory context. Various European standards deal with ductwork airtightness but none of them fully describes the protocol to perform the test. As a result, some countries have developed their own protocols.


The objective of this webinar is to present existing European standards & protocols for ductwork airtightness tests and compare the different approaches.


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