Building and ductwork airtightness requirements in Europe – Comparison of 10 European countries

Mandatory building airtightness testing has come gradually into force in the UK, France, Ireland and Denmark. It is considered in many other European countries because of the increasing weight of the energy impact of building leakage on the overall energy performance of low-energy buildings.
This study analyses recent developments in 10 Europeans countries on the following aspects:
- requirements regarding building airtightness in EP- regulation
- requirements in specific energy programmes
- airtightness testers schemes
