1979
ECBCS AIC (Air Infiltration Centre – Annex 5) Annex 1 had indicated that many questions existed regarding air infiltration
Policy in several countries: Built tight!
Airtightness was research topic in some countries
1986: AIC became the AIVC AIR INFILTRATION AND VENTILATION CENTRE

The participants (TAAC members and guests) are from Belgium, Canada, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Hungary, Ireland, Latvia, Norway, Poland, Spain, Sweden, UK and the US.
The scope 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

About AIVC
EU EPBD article 19a –feasibility study of inspection of stand-alone ventilation systems
EPBD 2018 – Article 19aFeasibility study
The Commission shall, before 2020, conclude a feasibility study, clarifying the possibilities and timeline to introduce
• the inspection of stand- alone ventilation systems and
• an optional building renovation passport that is complementary to the energy performance certificates, in order to provide a long-term, step-by-step renovation roadmap for a specific building based on quality criteria, following an energy audit, and outlining relevant measures and renovations that could improve the energy performance.
