The prediction of air infiltration through building components. The assembly of a device to measure air infiltration through components with a suggested method of producing data which could be used to form the basis of aprediction model.

Reviews air infiltration measurement methods, prediction models, and flow through components of buildings. Attempts to construct a device capable of measuring air flow through a building component under a given pressure difference and to investigate the existence of a coefficient which, when multiplied by the pressure difference, raised to an exponent, will yield the air flow through that component. Components were tested under differing pressure differences and the testing device was calibrated by a tracer gas technique. Concludes that it is possible to perform pressure/air flow tests quickly and efficiently, and cites an acceptable equation in respect to the coefficient.
