ATP effectiveness levels The project must establish ATP Luminance performance ranges (in RLU) for each surface for each level of cleaning effectiveness (effective cleaning, needs improvement, ineffective cleaning). These ranges must be specific to the ATP meter used and can be adjusted using actual performance data from the building.
Scoring Facilities must achieve a score of “needs improvement” or “effective cleaning.” If the audit results in ranking of “ineffective cleaning,” teams should use the results to inform on areas of improvement. If those improvements are implemented an additional audit can be performed until the required score of needs improvement is achieved.
