The article compares the definitions and requirements in various standards (ASHRAE 62, DIN 1946, CEN CR 1752, CIBSE guide A, ISO TC 205) related to ventilation and indoor air quality in terms of health, comfort and productivity. It explains how standards, especially CEN CR 1752, define indoor air pollution (use of olf and decipol as well as carbon dioxyde and water vapour concentrations) and outdoor air pollution .

The minimum required ventilation airflow rates and the analytical methods for their calculation, as defined by ASHRAE 62, DIN 1946 and CR 1752 standards, are given and compared for dwellings, offices and meeting rooms. The article explains how they take into account tobacco smoke.

Recent bibliographical references are mentioned to illustrate the choices made in the standards, for example about IAQ and productivity, or about the role of HVAC systems (especially filters) on indoor air quality.

After recalling the definition of ventilation efficiency, the author finally describes the different types of ventilation systems (window opening, natural, mechanical, hybrid) and their advantages and inconveniences). He concludes that only mechanical or hybrid ventilation systems can ensure an optimal indoor air quality with an acceptable energy consumption.
