Over the past few years, there has been an increasing number of airtightness tests performed in Europe either for specific high performance buildings programmes or for a wide range of buildings in regulatory contexts. This has led to the development of competent tester schemes to contain potential legal and competition issues.
The objective of this webinar was to give information on the status and trends in airtightness testing in the UK, Belgium,Germany, Czech Republic, France, Denmark, Ireland and Sweden including the details and feedback on competent tester schemes.

While building airtightness is a key concern in Nearly Zero-Energy Buildings in most European climates, there exists already a wide range of commercially-available products specifically designed to minimise leakage in building envelopes.
The objective of this webinar was to give information on the performance and properties of these products based on research including laboratory and field tests. The speakers also provided information on standards already published and under development on this subject.

The implementation of the EPBD recast puts increasing pressure on the market to achieve better building and ductwork airtightness: for most European climates and countries, good airtightness levels are necessary to achieve nearly zero-energy buildings. You will learn about legislative drivers that have brought to light new concerns and stimulated new initiatives. We will discuss recent trends in European regulations as well as field studies supporting the development of competent testing schemes.
