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.

Purpose of the work
Clear and substantiated instructions for airtightness measurements of high-rise buildings, taking into account the particular requirements resulting from building height

Purpose of the work
A procedure for the preparation of buildings for airtightness checks in compliance with legal requirements was to be defined in a standard. It should be possible to transfer the measurement result directly into the energy performance calculation as specified in DIN V 18599 without making any mathematical corrections. Checklists in the standard should largely eliminate the need to consult previous publications on interpretation issues.
