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

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.
