Luftdichtheit der Gebäudehülle (6 UE)


incl. 19% VAT

In connection with airtightness, we often hear the topic of mould or the demand for "breathing houses". We therefore start by explaining why airtightness is important.

In contrast to the statutory minimum standard, particularly good airtightness is even a MUST for passive houses.

Stricter requirements apply to the implementation of the differential pressure method in accordance with DIN EN 13829, which is used to measure the airtightness of the building.

How this works and what influence the result has is discussed in detail.

In the final section, we look at what you need to consider when planning and constructing a building to ensure that it is airtight.

The German Energy Agency (dena) recognises the "Airtightness" learning module with 6 UE (teaching units).

Learning objectives

The following learning objectives are to be achieved with this learning module:

  • Knowledge of the most important reasons for an airtight building envelope
  • Knowledge of possible problems caused by airtightness and solutions
  • Knowledge of the framework conditions (legal and passive house standard)
  • Setup and implementation of the standardised measurement, interpretation of the results
  • Knowledge of the most common leaks and how to avoid them in planning and execution
  • Ability to calculate heat losses due to leaks
  • Realisation: airtightness is the most economical way to save energy


History, reasons for an airtight envelope, specifications, standards, airtightness measurement procedure, leak detection, practical tips, planning principles, implementation, avoidance of typical errors

Target group

Architects, specialist planners, energy consultants, executing trades
