Pressure equalization of rainscreen facades: Analysis of the field data in the frequency domain

This paper reports the field measurements concerning pressure equalization of rainscreenfacades carried out at the Technical University of Eindhoven (TUE) in the Netherlands. The field facilityincluding the details of test panel, meteorological tower, instrumentation, data collection and analysis ispresented. Results of investigations into cavity response for various leakage and venting configurations arediscussed. Frequency domain techniques have been utilized to show the influence of wind as well asfacade characteristics on the pressure equalization performance. Further, this paper presents an earlyattempt to synthesize the experimental results into existing building codes.
