Maintaining and enhancing good indoor air quality is best done through a program of regular inspection, repair, and remediation. The following will help:

Conduct a Baseline Building Audit	Good IAQ management begins with an informed understanding of existing conditions. Start with a whole building walkthrough, including occupied spaces, mechanical systems, and the building exterior. Take simple measurements of pressure relationships and air flow patterns, as appropriate. Note where more detailed measurements may be needed at a later date. Keep detailed records. Use the I-BEAM program, available from the U.S. Environmental Protection Agency.
Maintain Records	Develop an organized system to obtain and maintain the following building records: "As built" blueprints, including modifications to reflect current conditions. Up-to-date drawings of all tenants' build outs and interior renovations. Records of major space use changes not reflected in original design. Drawings of pressure relationships. Operating and Maintenance Plans and Schedules. Historical Occupant IAQ complaint logs (if available). Inventory of products and materials that are sources of pollutants, with MSDS sheets and related information.
Enlist Occupants	Effective, low cost IAQ programs succeed best when they involve tenants. Educating occupants to be alert to and problems and to report them promptly greatly multiplies the eyes and ears of building maintenance personnel.
Evaluate Complaints	Tenant complaints may alert you to systemic problems that go beyond the actual gripe. For example, if occupants complain about stale air, the real culprit may not be your HVAC system. It could be that a tenant is trying to squeeze too many employees into the available space.
Maintain Open Communications	Open communications with occupants benefits everyone. It alerts you quickly to potential issues and creates a more comfortable environment for tenants. Over time, this helps reduce tenant turnover, which keeps costs down.
Be Pro-active if Questions Arise	Tenants and others using your facility need assurance that building managers and owners are on top of any IAQ issues that may arise. Therefore: Respond quickly. Listen, be understanding, and show compassion. Keep everyone informed. Document what you learn and the actions you take. Be in charge.
