The round-robin test of Czech airtightness providers was organised in order to obtain information about the measurement equipment generally used and in order to compare the test results given by different technicians operating with different devices. All the participants measured the same building under very similar conditions. The preparation...

The contribution informs about the foundation of a professional network of Czech airtightness test providers and gives basic information about the organisation and activities of this association.An idea of closer cooperation between Czech building airtightness test providers has existed for several years. (one outcome of such activities...

The actual question is as follows: “Is the building envelope of the first passive house in China sufficiently airtight?” To determine air-tightness in China, a pressure differential test was to be conducted. First, a number of questions had to be answered. What building system is used and which materials are implemented? Who will...

The new Part 7 of the Thermal Insulation Standard DIN 4108 describes the permanent design of the airtight layer of heated or air-conditioned buildings. In the chapter on requirements, some terms have been redefined. However, the required values for the maximum air change rate are stipulated in the current EnEV...

To describe the quality of adhesive joints and connections for airtight layers, our research includes comprehensive investigations into the effect of different working conditions and accelerated aging. Existing methods for testing adhesion are analysed and adjusted. The evaluation of adhesives’ suitability for permanently...

Today, labels introduced in some countries to certify standardised low energy buildings, such as ‘Passive House’ in Germany and ‘Minenergie’ in Switzerland, are becoming increasingly applied in Europe.  Both labels explicitly require a threshold level of airtightness (0.6 air changes per hour (ACH) at 50 Pa). For timber frame...

The air tightness of building has been a serious problem over the last 30 years. In 1979 the international Air Infiltration Centre (AIC) was erected within the International Energy Agency (IEA) platform. Infiltration of cold air into buildings needs to be heated to reach to a comfortable indoor climate. But the energy penalty due to that should be...

We have developed a simple model to estimate ductwork leakage and heat conduction losses in steady-state conditions for a balanced ventilation system. Implemented in a spreadsheet, it allows us to calculate their impact on heat recovery efficiency consistently with EN 15241 without the need for a dynamic simulation tool. One case study...

The glossary gives the translation (English/German - German/English) of more than 1000 terms related to air infiltration and ventilation.

This document is intended for use as a supplement to AIRGLOSS (AIVC TN 5). All terms in AIRGLOSS are included together with some supplementary materials for which definition was considered superfluous.

Der ganzheitliche Ansatz für die Bewertung der lüftungstechnischen Maßnahme (Systeme zur Wohnungslüftung siehe Bild 1) spiegelt sich im zu erstellenden Lüftungskonzept für die gesamte Nutzungseinheit wieder (s. Bild 2 und Bild 3). Dieser Ansatz ist unter anderem auch in der überarbeiteten Norm E DIN 1946...
