The Air Infiltration and Ventilation Centre's first glossary of ventilation terms was published in 1981 as AIVC Technical Note 5 and contained definitions of over 700 words relating to air infiltration and ventilation. Since then, many definitions have been updated and new terms have been added.

The revised glossary (1992) incorporates the changes that have been made since the first edition was published. It also includes the principle terms associated with ventilation technology. The revised terms have been compiled from a variety of sources including those listed in the bibliography. The intention of the document is to promote a more uniform use of terms in the area of ventilation.

The glossary consists of main terms with definitions followed by any subsidiary terms. The main terms are in alphabetical order. The basic entry has the following format:

Minimum Ventilation Requirement
The minimum quantity of outdoor or conditioned air entering a building, which is needed to maintain acceptable indoor air quality. (See Acceptable Air Quality)

Subsidiary terms are bracketed and appear below the definition in italics, as in the example above. Definitions for these subsidiary terms are given in their alphabetically correct place.

Acceptable Air Quality
Air in which there are no known contaminants at harmful concentrations as determined by specialist authorities and with which a substantial majority (80 % or more) of the people exposed do not express dissatisfaction. (ASHRAE 62-1989).
