Experimental techniques for ventilation research.

Reviews experimental techniques for determining the infiltration characteristics of buildings. Discusses the use of wind tunnel models to determine surface pressure distributions and ventilation rates. Reviews the measurement of open areas and leakages. Discusses correlation of measured leakage and ventilation. Describes the British Gas method of measuring ventilation rates using tracer gas. The system, known as "Autovent" provides a constant concentration of tracer gas and can be used for the continuous monitoring of ventilation rates.
