Purpose of the work
Over the past years, the industry has launched a great number of products facilitating the airtight installation of sanitary fixtures in the airtight building envelope. However, the pre-wall mounting racks of cisterns remain a “key point” for assessing the airtightness of pre-walls.
Method of approach
As part of the rehabilitation of an indoor swimming pool, “airtight” pre-wall mounting racks were developed and used. This was due to the flush buttons causing “seepage” of the compound seal.

Purpose of the work
The German Industrial Standard DIN 4108-7 has been the standard to stipulate the requirements as well as recommendations for planning and implementing airtight construction for a long time (since 2001). However, the principles of airtight building have not yet been well established in general building practice.

Purpose of the work
Many top-floor apartments and single-family homes from the ’80s and ’90s had been insulated in the roof area using aluminum-clad panels or PE foils and had frequently been covered with profiled wood. These buildings suffer from a significant lack of airtightness that can be retrofitted from the inside with a high technical quality. The improvement in airtightness achieved by this approach in most cases shows better results than a retrofit from the outside.

Purpose of the work
Is it possible to estimate an air infiltration flow rate, based on infrared images?
Method of approach
Laboratory tests and numerical simulations
Content of the presentation
This paper discusses laboratory measurements on a small test house. IRT measurements and (de)pressurization tests were performed on different types of junctions, e.g. at the window-wall interface. The results were analysed by calculating the temperature factor, to compare IRT images from different joints.

Purpose of the work
When it comes to evaluating the quality of building work, technical and legal perspectives often clash. This is probably particularly true when it comes to evaluating the airtightness of building envelopes. This presentation is an attempt at clearing up frequent misunderstandings and at formulating questions that would help to combine the technical and legal ways of assessing quality in the most practical manner possible.
TightVent Europe and the Air Infiltration and Ventilation Centre are organizing the webinar "Building airtightness improvements of the building stock - Analysis of European databases" to be held on Tuesday January 19th, 2021 at 10:00-11:15 (CET). The webinar aims at presenting three major European databases (in the UK, Flanders and France) and also at comparing their structures and their measurement data acquisition protocols. Weaknesses and strengths in the different aspects of the existing database setups will be identified.
