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.

We are pleased to announce that the AIVC 2022 Conference “Ventilation Challenges in a changing world" is now accepting abstracts & proposals for topical sessions. The Conference will be held on October 5-6, 2022, at the Hilton Hotel, in Rotterdam, the Netherlands. It will be a joint event combined with the 10th TightVent and the 8th venticool conferences.

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.

Purpose of the work
What is the status quo of airtight building in Germany? Are we well on our way or still far from the target? What about measuring practice in Germany? Should we concentrate on the documentation of measurement results or is it more important to exert a positive influence on the building process overall? Which requirements and targets are set by the legislators, which by the development banks?

Purpose of the work
By way of practical examples, the presentation shows that decentralized ventilation systems do neither make airtightness measurements more difficult nor distort them, and despite the requirements for a high level of airtightness for buildings also ensure good indoor air quality.
