How airtight is my building?
Airtightness is a fundamental characteristic of a Passive House building. A lecture session delves deeper into the planning principles and requirements for large or very tall buildings.
The significant challenges to airtightness testing of skyscrapers, including the stack and thermal effects, will be investigated and the new Passive House Tall Building Airtightness Measurement Guidelines will be presented to conference attendees.

Airtightness in Central Europe - Planning Principles for Airtightness
|Passive Houses gain much of their proven comfort and health aspects as well as longevity from greatly reduced infiltration. Passive Houses regularly achieve very high levels of airtightness with the majority of cases outperforming the 0.6 ACH requirement. As soon as the airtightness of the building fabric becomes an accepted design objective it is moreover a particularly cost-effective means to boost the energy performance of buildings. With increased demand, the availability of specialised products has improved and is currently evolving into comprehensive airtightness systems that provide ready-made solutions for all standard detailing found around any building envelope.|
Airtightness in the Heidelberg Bahnstadt
|Thomas Kirtschig, Matthias Laidig|
|Using various examples from the Bahnstadt Heidelberg, we show how we proceed with airtightness measurements in larger buildings, in which difficult measuring conditions sometimes occur, as well as how we deal with them and why airtightness measurements in Passive Houses incur lower costs than in other buildings. Over the past 25 years, we have seen significant developments in the air sealing of buildings. Various measurement methods are shown which provide an adequate check of the realized building airtightness.|
Measuring airtightness in highrise buildings
The standard ISO 9972 is not always helpful when measuring the airtightness of high-rise buildings. There are many points to consider, especially due to the stack effect. These points are examined, and the Passive House Institute presents a guide for the airtightness measurement of skyscrapers.
