Air leakage in building envelopes is responsible for a large portion of the building’s heating and cooling requirements. Therefore, fast and reliable detection of leaks is crucial for improving energy efficiency.

Throughout the world more and more high-rises or very tall buildings are being checked for air leaks. In February 2021 air permeability measurements were carried out in a 125-meter-high building with 37 storeys. This is the first time that a building of this height was measured in Europe. This report provides information about the planning process, the measurement concept and the measurement results.

Content of the contribution
At the beginning of 2019 I received a request to measure four so-called isolation rooms which were intended for a new hospital. Such isolation rooms are standard practice to prevent the transmission of germs and viruses from patients with contagious diseases or to patients suffering from immunodeficiency.

Inhalt des Vortrages
Anfang 2019 erhielt ich eine Anfrage zur Messung von vier sogenannten Isolierzimmern, welche beim Neubau eines Krankenhauses vorgesehen waren. Solche Isolierzimmer werden regulär betrieben, um die Übertragung von Keimen und Viren von Patienten mit ansteckenden Krankheiten oder zu Patienten mit Immunschwäche zu verhindern.

Purpose of the work
In residential construction a large number of decentralized air handling units which work alternately in pairs and (thus also referred to as push/pull units) is used to serve the apartments. These ventilation systems ensure the exchange of air in residential buildings, while at the same time reducing ventilation heat losses. These air handling units are intended to ensure a regulated exchange of air but are also equipped with regenerative heat exchangers which allow for exhaust air heat recovery.
