Your IAQ audit report should identify each system or space audited; include a summary of the audit procedures for indoor spaces, exterior spaces, and HVAC systems; and a summary of the results. A list of all IAQ-related issues or areas of opportunity discovered during the audit must be provided in the report. Additionally, the report must document that the remediation of all no-cost issues have occurred before the end of the performance period. For issues requiring costs to remedy, the report must establish a timeline and strategy for addressing each issue. See this sample report for examples.
