LoginLeakages 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...

Recommendations for the optimal and lasting sealing of joints from a hygro-thermal perspective | 2017 | English
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...
Environmental control (heat, air and moisture flows and their effects) started 90 years ago on Prairies of Canada and USA. It has always been based on occupant’s interest in a better indoor environment and driven by builders. More recently, when energy efficiency and durability considerations became part of socio-economic...
When building is set on very low negative pressure, use the Radon sniff-equipment called RAD7 to count radon at places where thermal imaging camera tell there is draft that can be assumed tob e leaks from the ground. If the found leakages are from the ground it often show higher level of Thoron, Radon and Polonium values, than the...
