Air infiltration in buildings has multiple consequences on energy use and indoor environmental quality which depend on the location and distribution of leakages. Among others, pollutant infiltration and air draft are highly affected by leakage distribution. In current practice, leakage detection is frequently performed together with an airtightness test. Leakage detection methods allow to identify the locations of the leakages, but in most cases do not allow to quantify the amount of leakage corresponding to each identified leakage. This stresses the need for methods quantifying leakages through individual building components. In addition, such methods would help contractors to assess the quality of on-site execution, known to have a major impact on building airtightness.

The objective of this webinar was to discuss existing methods to measure the airtightness of individual buildings components.

This webinar was organised with the support of TightVent Europe (www.tightvent.eu)  and  the Air Infiltration and Ventilation Centre  (www.aivc.org).  Both initiatives are facilitated by INIVE (www.inive.org).

Presentations and Speakers:

• Building component performances as an answer for airtightness issues –existing quantification methods, Martin Prignon, UCLouvain, Belgium
• Uncertainty of effective leakage areas determination through reductive sealing technique, Vitor Cardoso, FEUP, Portugal
• Bias and precision errors in the measurement of building component airtightness with direct component test, Martin Prignon, UCLouvain, Belgium
• Comparison of airflow and acoustic measurements for evaluation of building air leakage paths in a laboratory test apparatus, Benedikt Kölsch, DLR, Germany
