Airtightness of multifamily residential buildings in Czech Republic – theory vs. reality

Despite their favourable A/V ratio, large multifamily residential buildings in Czech Republic often show worse airtightness (n50, qE50 or both) than small single-family passive houses erected by means of similar construction methods The analyses presented point out several reasons behind...

Luftdichtheit bei Mehrfamilienhäusern in Tschechien – Theorie vs. Praxis

Trotz ihres günstigen A/V-Verhältnisses weisen große Mehrfamilienhäuser in der Tschechischen Republik häufig eine schlechtere Luftdichtheit (n50, qE50 oder beides) auf als kleine Einfamilien- Passivhäuser, die mit ähnlichen Baumethoden errichtet wurden. Die vorgestellten...

Ensuring airtightness when retrofitting existing buildings with prefab components

Germany has already garnered some experience with serial refurbishments of its existing building stock. When mounting a heat-insulating building envelope during serial modernization you usually incorporate an airtight barrier as well. First of all, however, the question arises as to where to install...

Luftdichtheit bei der seriellen Sanierung

Mit der seriellen Sanierung von Altbauten wurden und werden in Deutschland bereits erste Erfahrungen gemacht. Die Anbringung einer seriell konzipierten wärmedämmenden Gebäudehülle schließt die Herstellung einer luftdichten Schicht in der Regel ein. Es stellt sich allerdings zunächst die grundlegende Frage...

Measuring airtightness of 100-meter high-rise buildings (lessons learned) – part 2

Worldwide, the demand for airtightness tests of tall buildings with a height of approximately 100 m is increasing. This report provides information on the planning and measurement concept for testing the entire building as a “single-zone” and presents the results and findings of the airtightness tests. The test set-up and the tests as such...
