(Duesseldorf, 19/07/2005) Guideline VDI 4300 Part 9 covers the measurement strategy for determining carbon dioxide in indoor air. The procedure for investigating the compliance with a guide value as well as the ventilation situation in a room is explained in detail. Further on the guideline deals with the calculation of ventilation requirement.

CO2 is frequently used as a general indicator of indoor air pollution of human origin. Particularly in naturally ventilated rooms which are regularly occupied by a relatively large number of people, for example in school rooms or auditoriums, the air quality can decrease rapidly. Without required ventilation the corresponding guide values can sometimes be considerably exceeded. The Guideline series VDI 4300 describes general requirements relating to the measurement of indoor air pollution and the boundary conditions which are important for the individual substances and classes of substances which need to be taken into account before or during measurement.
