European standards or specific programmes rules describe ventilation airflow measurements at terminal devices according to different protocols. Experience shows that these protocols rarely address the assessment of uncertainties. The main goal of the Promevent project was to develop a reference protocol...

Since 2008 in France, all measurement of building envelope airtightness performed according to the EP-regulations have to be performed by a certified operator. This certification includes a yearly follow-up we use to build up a highly detailed database which includes data of about 90,000 airtightness measurements...

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...

Leakages in the building envelope may cause severe damage to a building and thus inevitably become an issue not only for building physics, but also for the law. In the case of such legal disputes, the different perspectives of scientists and lawyers frequently turn out to be a problem. This is further acerbated by the different levels of...

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...

With the German Energy Savings Regulation EnEV 2014 the legislators have qualified the requirements for large apartment buildings (VL > 1.500 m³). In addition to the air change rate (n50 ≤ 3,0 h-1 or n50 ≤ 1,5 h-1 depending on the ventilation technology used) the envelope-based air permeability (q50 ≤ 2,5 m³h-1m-2) is now also required...

It has been ten years since the publication of a draft proposal, and now, many hundred measurements without a binding standard for such a sensitive area later, the day has finally come. We have a standard dealing exclusively with the airtightness of clean rooms. The presentation shows the way to the new VDI 2083/19 and...

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...

In response to the questions of the three regional governments that had found quality deficiencies with regard to airtightness tests, the Belgian professional association has developed a control software and has organized the certification of airtightness testers. There are two different quality frameworks in Belgium. One was...

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...
