LoginEstablished methods of computational fluid dynamics (CFD) have been applied to predict the details of airflow, contaminant dispersal and thermal transport within isolated zones, yet zone transport processes do not occur in isolation.
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 the airflow pressure losses at the junctions of ducts in ventilation systems are taken into account, the analysis becomes more complicated since no unique value for the static pressure is associated with a junction.
Near-extreme solar irradiance, ambient dry-bulb and wet-bulb temperatures are fundamentaldata for determining the peak building cooling load. Design solar irradiance has beenseparately and independently selected by both ASHRAE and CIBSE.
Damit ein Gebäude seinen Anforderungen hinsichtlich der Standsicherheit, der Energieeinsparung und der Hygiene gerecht wird, ist es nicht nur erforderlich, dass die Luftdichtheitsschicht in ihrer ebenen Ausbildung dicht ist, sondern auch, dass die
An den grundsätzlichen Anforderungen, wie schon bei dem 1. Europäischem BlowerDoor-Symposium aufgezeigt, hat sich nicht geändert bzw. hat die Praxis doch einige Punkte aufgeworfen.
Das Thema Luftdichtheit von Gebäuden ist nicht ganz neu. Schon in den 1970er Jahren wurde es gerade in den nordischen Ländern intensiv erforscht. Das Magazin Air Information Review veröffentlichte im August 1980 (Ref. 1, Abb.
So that a building meets its requirements regarding stability, energy conservation and hygiene, it is not only necessary, that the airtightness layer is really airtight in its plenary formation, but also that functionality is given within the rang
Im Mai 2006 ist die internationale Messnorm ISO 9972 veröffentlicht worden.
The fundamental requirements, already presented at the 1st European BlowerDoorSymposium, did not change, respectively practice has brought up some points.
What is a pure area? In the case of the production of smallest structures, e.g. in production of microprocessors, or in the clinical range, e.g. in operating rooms, momentous problems can arise as a result of impurities in air.
Der Leckageweg beeinflusst die Infiltrations- und Luftdruckbedingungen im Gebäude. Die Hauptzielsetzungen dieser Studie waren, die Verteilung der Leckageorte und der thermischen Brücken in Ein- und Mehrfamilienhäusern zu analysieren.
In May 2006 the international measuring standard ISO 9972 was published. It replaces the first edition from the year 1996 and is in large parts identical with the EN 13829:2000, which in Germany was published as DIN EN 13829 in February2001.
A ‘standard’, as a quick look in a dictionary will tell us, is an ambiguous term: whereas technical standards refer to expertly developed and scientifically reasoned yardsticks for a comparative assessment of quality, legal standards refer to rule
Diese Studie berichtet über Lüftungsmessungen und die Ergebnisse von Bewohnerbefragungen von 102 neu errichteten Einfamilienhäusern in Finland.
Thermography is a helpful means at the visualisation of leakages on the wind and airtightness level.
All times the building cover was made as airtight as possible. With massive constructions it was all above the plasterwork, which took over the sealing function.
The interrelation between requirement and implementation and/or realization of the ventilation technique is represented in fig. 9 exemplarily for a building, similar to the example from DIN 4108 - 6 with and ventilated effective area by 205,6 m2.
Sich ändernde Bedingungen der allgemeinen tschechischen Baupraxis führen zu einer ernsthafteren Berücksichtigung der auf die Luftdichtheit bezogenen Probleme - aus verschiedenen Gründen: - Einführung von empfohlenen n50-Werte in den tschechischen
Due to practiced building practice in the past decades the preservation of a sufficient room air quality usually proved as unproblematic. The necessary air-change was already regularly ensured by the so called free ventilation of dwellings, i.e.
Manufacturing and development processes in the electrical industry (microchips), the technology for smallest elements with high precision, the medical research and the food technology as well as operating theatres require laboratories and/or areas
