NATURAL VENTILATION IN LARGE AND MULTICELLED BUILDINGS - THEORY, MEASUREMENT AND PREDICTION
In this programme of work, methodologies for determining infiltration rates of large and complex buildings have been established. Solutions to this hitherto intractable problem have been obtained using a combination of theoretical and experimental studies. Theoretical considerations suggested that comprehensive information regarding interzonal air movements might be obtained from experimental techniques using multiple tracer gases. Field measurements to determine interzonal flows were carried out in office buildings using automated measurement systems developed for this purpose. It was recognized that, in most circumstances, simpler techniques, which would give less comprehensive but nevertheless useful information, were needed. Such a simplified technique has been developed. Theoretical and experimental work showed that, with this technique, it is probably sufficient to seed part of a complex building with a single tracer gas in order to measure the overall infiltration rate to a good approximation. Prediction models have also been used to determine the effectiveness of draughtstripping windows on the energy consumption of an office building. The predicted infiltration rates compared well with measured values. Energy calculations showed that, for this particular building, draughtstripping windows has reduced by 21% the seasonal gas consumption.
