The TightVent Airtightness Association Committee (TAAC) continues to meet 4 times per year. Due to the COVID-19 pandemic, no physical meeting has been held since 2019 but the next one is now planned for October 2022 before the AIVC-TightVent-venticool joint Conference in Rotterdam!

During the last 4 TAAC meetings the group’s discussions focused mostly on:

• Building airtightness measurements in high rise buildings, based on presentations by Christophe Delmotte (CSTC, BE), Stefanie Rolfsmeier (Blowerdoor Gmbh, DE) and Valérie Leprince (INIVE, FR)
• Updates on airtightness and ventilation regulations in TAAC participants’ countries (Belgium, Czech Republic, France, Germany, Greece, Netherlands, Spain, Switzerland & UK)
• New products such as the AeroBarrier presented by Simon Tölke (MEZ-Technik, DE), and the VentiFlow-mk2, the AirTightnessTester & Ultragraphyx presented by Niek-Jan Bink (ACIN Instrumenten, NL)
• New acoustic methods to locate & quantify leakages presented by Benedikt Koelsch (DLR, DE).

The Air Infiltration & Ventilation Centre (AIVC) in collaboration with TightVent and TAAC are currently developing a series of Ventilation Information Papers (VIP)s to explain trends in building and ductwork airtightness in various countries. There is also work in progress to assess the possibility of developing a European database on building airtightness.
