Domestic low energy: new housing.

        

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.

Increasing efficiency.

         

Inhabitant behaviour with regard to the use of air intakes. Measurement set-up.

In order to monitor the use of movable air intake grilles by the inhabitants a measurement system is set up in 9 apartments with anatural ventilation system in a building in Namur. The apartments to be monitored are part of an apartment building in Namur wherein a measurement campaign is going on in theframework of a CEC-DGXVII energy demonstration project. A description of the building is given in annex.
