2nd AIVC Conference "Building design for minimum air infiltration" Stockholm, Sweden, 21-23 September 1981

Gives a summary of the existing types of air infiltration measurement techniques and instrumentation using tracer gases. Describes automated air infiltration instrumentation used by researchers in the US, Canada, the UK, Denmark, Sweden and Switzerland. The equipment can operate in the decay mode, constant flow mode and the constant concentration mode. Most of these instruments are microcomputer or microprocessor based and capable of performing real time determination of the air infiltration rate in multizone buildings and monitor parameters such as temperature, wind speed and energy consumption. Summarizes two simple techniques - the air bag or container method and the average infiltration monitor, developed by researchers in the US.
