LoginThe fan pressurization method is a common practice in many countries for measuring the air leakage of houses. The test results are sensitive to uncertainties in the measured pressures and airflows.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
When designed and operated adequately, natural ventilation (NV) can improve the buildings’ energy efficiency and indoor environmental quality.
Respiratory infections are transmitted by droplets and droplet nuclei generated by human coughing, sneezing, and talking.
The discomfort prediction inside buildings by means of correlations able to estimate people subjective response from indoor conditions has been widely investigated with the purpose of supporting design, commissioning and operati
This study aims at obtaining feedback from occupants of low-energy retrofitted houses concerning the indoor environmental quality (IEQ) and the building systems in their homes.
Ventilation systems assume that the outdoor air quality is better than the indoor air quality at al times as they use outdoor air to dilute pollutants emitted by humans, activities, the building itself and other objects.
Current building regulations are designed to ensure that buildings, including newly built and retrofitted residential dwellings, are more energy efficient.
In this paper various direct reading instruments and techniques used in air monitoring are reviewed. Principles of operation are described, pointing out advantages and disadvantages of using such instruments.
The book of proceedings of the 13th International BUILDAIR Symposium "Airtight Buildings, Thermography and Ventilation Systems in Practice", held on June 2-3 2023 in Hannover, Germany. Contains 36 abstracts.
This presentation is the recording of the first 100 airtight tests in Greece, from 2010 until today.
Purpose of the work
I would like to report on lessons learned in the field regarding two measurements at a special, particularly airtight and unusual building: A "concrete shell for CO2 storage in recycled concrete aggregates".

Wie groß ist der energetische Beitrag für energieeffiziente Gebäude aufgrund der Undicht-heit von Abluftklappen für Dunstabzugssysteme?
Weltweit steigt die Nachfrage nach Luftdichtheitsprüfungen von hohen Gebäuden mit einer Höhe ab ca. 100 m.
Diese Präsentation behandelt Aufzeichnungen der ersten 100 Luftdichtheitstests in Griechenland von 2010 bis heute.
Purpose of the work
In Denmark, a manufacturer and dealer of vapor barrier membranes has observed unusual behavior. The membranes were installed in a small house and show that the system can be set up and be tight.
Worldwide, the demand for airtightness tests of tall buildings with a height of approximately 100 m is increasing.
