Comparison of two IAQ calculation methods

Calculating the contamination concentrations in a space or the required ventilation for a spacehas been a difficult and confusing part in the application of the IAQ Procedure ofANSI/ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality. Appendix D ofASHRAE Standard 62 currently presents one method for performing these calculations, but itis limited to the steady-state analysis of a single zone.
