19 January 2021, Webinar – Building airtightness improvements of the building stock- Analysis of European databases

Air infiltration in buildings has multiple consequences on energy use and indoor environmental quality. Therefore, in the last 10 years many countries have introduced requirements for building airtightness in their EP-regulation. Those requirements often prescribe that a test is performed by a qualified tester and that every test performed is recorded in a database.  Hundreds of thousands of data are now available in Europe.

8 October 2013, Webinar – Building Airtightness Solutions: System approach and characterisation of air barrier and moisture management systems

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 natural pressure differential – Wind infiltration. Results from a long-term measurement

Purpose of the work

The pressure differential at the building envelope results from wind pressure and thermal lift. European and German standards include in the calculation of corresponding infiltration the parameters wind speed, temperature differential, and the wind pressure coefficient from building inflow and outflow. This long-term measurement is to compare the calculations to the pressure differentials measured.
