The balance of the amount and quality of outdoor air getting in and indoor
sources of emissions is of major importance of indoor air quality; this balance
is identifi ed by indoor/outdoor ratios, usually in the range of 0.5 to 1.7. Unfortunately,
indoor odor consequences are not yet considered when ventilation systems
are projected; in fact, they are addressed to provide makeup air, controling
ambient temperature, and or relative humidity control. If odor emission is a
problem, designing for this objective gives the worker a comfortable environment
to work in, minimizes concerns related to worker safety, and improves worker
attitudes, thus, increasing productivity.
