The proceedings of the first AIVC Conference are divided into five sessions: Alternative measurement procedures; Automatic monitoring using tracer gas techniques; Pressurization test methods; Correlation of tracer gas and pressurization measurements; Other measurements.

Five supplementary papers from the sixth AIVC Conference as follows: The performance of ventilation in an untight house; Influence of open windows on the interzone air movement within a semi-detached dwelling; Interpretation and error analysis of multi-tracer gas measurements to determine air movement in a house; Inhabitant's behaviour with regard to ventilation.

This handbook gives a comprehensive explanation of the theoretical and practical aspects of measuring important parameters for understanding air infiltration and ventilation within buildings. Discussed parameters include: airtightness of the building envelope and its component leakage paths; air exchange rates within a building and with the external environment; efficiency of the ventilation system; flow rates in the ventilation network. It has been designed so that material suited to differing levels of expertise is readily accessible.
