Establishing an airtight building envelope requires both materials for the surfaces and joining materials for the airtight sealing of joints between components and penetrations, as well as splices and overlappings. In wooden structures, airtight sheeting or sheeting materials are generally used as an air barrier on the surface. Any splices and overlappings are generally bonded with adhesive tape. Joints at adjacent components are often created using paste-like adhesive compounds. DIN 4108-7 (airtightness of buildings) provides a large number of examples of joints with adhesive bonds.

Purpose of the work
Is a ventilation system mandatory in airtight buildings? To what extent can users still be responsible for ventilation in modern buildings?
Method of approach
Evaluation of decision-making criteria for ventilation; normative specifications for the ventilation concept; energy efficiency potential of ventilation

Purpose of the work
This paper deals with the feedback of a full of a ventilation system reconditioning in a non- standard sealed building. This volume was previously retrofitted and immediately shows many difficulties to maintain good indoor air quality in some parts of the occupied volume. Indeed, a permanent well functioning of the ventilation system is essential in a sealed building without openings to ensure a good indoor air quality.

Purpose of the work
This work presents multiple in-situ measurements of building components airtightness using a direct component testing. Its purpose is to highlight advantages, drawbacks and limitations of the method compared to other methods for measuring in-situ the airtightness of building components (e.g. the indirect method).

Purpose of the work
The aim of this study was to evaluate the evolution of the building airtightness over the time and to assess the long term performance (durability) of the air barrier system. For this purpose, several passive houses were repeatedly tested over a period of 6 to 11 years.

Purpose of the work
Presentation of the various requirements for airtightness of the building envelope arising during planning as well as the mandatory provisions resulting from standardization, regulations and certification: What can measurement service providers do to insure that the ensuing problems are identified at an early stage?
Method of approach
Summary of the experience gained over several years with air permeability measurements in consumer markets, commercial buildings and other large structures.
