Proper building operations and routine maintenance are critical to ensuring healthy IAQ. NIOSH looked at 500 of the first IAQ investigations that they had done and found that inadequate ventilation, contamination from inside the building, and contamination from outside the building were the top three sources of IAQ problems. These types of issues can be solved by doing things like maintaining the building heating, ventilation, and air conditioning (HVAC) system, following guidelines for ensuring adequate ventilation as office suites are rearranged, routinely cleaning office spaces and common areas, and properly storing cleaning and other chemicals that are used in the workplace. These actions help ensure proper IAQ and are all part of a well developed building operation and maintenance plan.
Building managers are often the first resource that building tenants and occupants turn to if they feel there is an IAQ problem. The following references provide information about investigating IAQ issues and controlling IAQ in the workplace.

Specifies minimum ventilation rates and IAQ that will be acceptable to human occupants to minimize the potential for adverse health effects. Whereas ASHRAE Standard 62 has always been considered a design standard for ventilation, building owner/operators should pay particular attention to Section 8 titled “Operations and Maintenance.” Section 8 offers guidance to the building owner/operator as to which ventilation components should be maintained, which tasks should be performed, and the minimum frequency for performing those tasks.
