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. More recently, the Indoor Air QualityDesign Tool (IAQDT) was developed by the National Institute of Standards and Technologyto facilitate these calculations and to include transient effects. This paper reports on theapplication of both methods to a single zone, showing the results of the each method to bevery similar, with exceptions occurring when transient effects are important.
