Based on the results of the FLiB e.V. research project „Evaluation of leakages in airtight layers – Recommendations for action for construction professionals”, testing methods in building practice for the detection, analysis, and evaluation of leakages are put up for discussion. One of the FLiB working groups has taken on the task of testing...

According to the legal regulations and the rules of technology (as generally accepted) new buildings are to be constructed permanently airtight. In order to do so, an airtight building envelope has to be carefully planned prior to the actual construction process. This is how it is stipulated in the German Industrial Standard...

Spain is not a country whre airthightness is considered in building process. We still think on our spacial climate conditions (Mediterranean wheather) and still unknown all about thighness, sealing, leakages consecuences, etc. And this is also for residential or industrial buildings. This Spanish BlowerDoor Test Record will bring us the opportunity...

The information about uncertainly is essential to correct interpretation of any measurement. Therefore, several authors investigated the reproducibility and repeatability of airtightness measurement during the last years. The experiments were carried out in real buildings of different size and in actual climatic conditions which complicates the comparison...

In an air traffic control tower, conditions for thermal comfort are crucial as the task of air traffic control requires high level of attention and vigilance. Comfortable conditions must be guaranteed all the time especially during extreme periods. Therefore, the HVAC system of a control tower is always composed by two, possibly three, identical...

As part of an airtightness test, you not only have to determine the air change rate and/or air permeability, but must also search for leakages. Extensive leakages must be documented. However, there are no regulations as to the method of leakage detection or the instruments that might be used. In comparison with traditional...

The policy instruments have been analysed mainly through information collected and discussions within the TightVent Airtightness Associations Committee, and with a literature review. Additional work is foreseen in the last quarter of 2016 to provide the symposium audience relevant information, in particular, through on-line questionnaires...

Windows according to the Passive House Standard 2016 require a ten times more airtight airtightness class (EN 14351) [1] than around 1990. The installation layer of the windows is constantly moving closer into the area of the insulating layer with possibly moisture-sensitive materials. Therefore, joint sealing of construction and connection joints...
