Owners and Engineers should focus on the largest source of documented IAQ problems. Literature suggests that over 50% of all IAQ problems are related to ventilation. Therefore, a successful strategy to improve IAQ must address ventilation.
Not all sources can be eliminated. People only contribute to a fraction of the overall pollution generated in a building. Standard 62.1-2004 no longer specifies ventilation only in CFM/person. A fixed building component now addresses contaminants not associated with the occupant or their activities.

Reduce Contaminants to Acceptable Levels through Dilution
Contaminants cannot be reduced to acceptable levels without dilution (outside air). Directly monitoring and controlling outside air is the best way to assure proper dilution levels are maintained within a building.
