Recent developments in TightVent Airtightness Associations Committee (TAAC)

In September 2012, TightVent Europe set up the TightVent Airtightness Associations Committee (TAAC committee) aiming to bring together airtightness testers associations with the primary goal to promote reliable testing and reporting procedures.  Since then, the committee has met nine times via internet and held two physical meetings, one in Hannover on June 6, 2013 (before the 8th  International BUILDAIR Symposium) and in Poznan on September 23, 2014 (before the 35th AIVC-4th TightVent-2nd venticool joint Conference). At present the participants ( are from Belgium, Canada, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Hungary, Ireland, Latvia,  Norway, Poland,  Sweden, UK and the US.

The scope of the committee includes various aspects:

  • airtightness requirements in the countries involved
  • competent tester schemes in the countries involved
  • applicable standards and guidelines for testing
  • collection of relevant guidance and training documents

As of today, TAAC has produced several studies ranging from comparisons of competent tester schemes, building preparation guidelines and airtightness testing costs, to reviews of airtightness requirements and applicable existing standards. Results of these studies are communicated between TAAC members and guests and presented in AIVC-TightVent conferences and workshops.
