19 January 2021, Webinar – Building airtightness improvements of the building stock- Analysis of European databases
10:00 Europe/Brussels

Air infiltration in buildings has multiple consequences on energy use and indoor environmental quality. Therefore, in the last 10 years many countries have introduced requirements for building airtightness in their EP-regulation. Those requirements often prescribe that a test is performed by a qualified tester and that every test performed is recorded in a database.  Hundreds of thousands of data are now available in Europe. Those data allow not only to perform interesting statistics on changes in the airtightness of the building stock but also to better understand and to anticipate building airtightness.

This webinar aimed at presenting three major European databases (in the UK, Flanders and France) and also at comparing their structures and their measurement data acquisition protocols. Weaknesses and strengths in the different aspects of the existing database setups were identified.

This webinar was organised with the support of TightVent Europe (www.tightvent.eu)  and  the Air Infiltration and Ventilation Centre (www.aivc.org).  Both initiatives are facilitated by INIVE (www.inive.org).
