Field studies in the transport of room air moisture by air movement. Feldversuche zum Transport von Raumluftfeuchte durch Luftbewegung.

Within the framework of the Dutch participation in IEA Annex XIV "Condensation" field experiments have been carried out to study airborne moisture transport in realistic circumstances. The experiments were done in an unoccupied 3-storey dwelling in Leidschendam in the Netherlands. The paper discusses some of the results.

A preliminary comparison of calculated building ventilation rates using six different pressure coefficient data sets. Vorlaufiger Vergleich von rechnerisch erstellten Gebaudeluftungsraten durch Verwendung sechs verscheidener Druckkoeffizienten-Datensatze.

As part of the Air Infiltration and Ventilation Centre's Numerical Database development programme, Wind Pressure Coefficient data are being collected from many published sources, much of which will contribute to the Centre's ownPressure Coefficient database. To ensure the compatibility and validity of the various data sets, a preliminary comparison has been carried out of the data in use. The work has concentrated on an analysis of the effects of Cp values, for vertical walls, on calculated wind driven infiltration and ventilation rates.
