Significant discrepancies have been observed among European countries, regarding the building and ductwork airtightness trends, attributed to differences between national policies, building practices and climate conditions. Minimum requirements for building airtightness are sometimes included in national Energy Performance regulations with a mandatory justification required by testing or applying a certified approach like in France, or with high default values making airtightness testing implicitly mandatory like in Belgium. On the other hand, other countries like Greece have no requirement on building airtightness and very few tests are performed to control it. Regarding ductwork airtightness, even if the significant impact of leaky ventilation ductworks on energy use and IAQ has been well established in the literature, the awareness on this issue is raising slowly.
A series of Ventilation Information Papers (VIPs) is being developed and published by the AIVC to present national trends and regulation on building and ductwork airtightness. The aim of this webinar was to present the current situation in three European countries based on these papers: France, Belgium and Greece.
This webinar was organised with the support of the Air Infiltration and Ventilation Centre (www.aivc.org) and TightVent Europe (www.tightvent.eu). Both initiatives are facilitated by INIVE (www.inive.org).
