ASHRAE Standard 62, in its current form, employs two procedures to provide acceptable indoor air quality (IAQ) in buildings. These are the Ventilation Rate and Indoor Air Quality (IAQ) Procedures. This standard further endeavors to achieve the necessary balance between IAQ and energy consumption by specifying minimum ventilation rates and IAQ that will be acceptable to human occupants. The Ventilation Rate Procedure provides only an indirect solution for the control of indoor contaminants. While it does allow for the use of cleaned, recirculated air, it does not allow the use of this air is to be used to reduce the amount of outdoor air required, or for the implementation of energy conservation measures, the IAQ Procedure must be used. The IAQ Procedure provides a direct solution by reducing and controlling the concentrations of air contaminants, through air cleaning, to specified levels. This procedure allows for both quantitative and subjective evaluation of the effectiveness of the air cleaning method(s) employed. The standard acknowledges that air cleaning, along with recirculation, is an effective means for controlling contaminants when using the IAQ Procedure.
