Subjective evaluation - Panel

Panel participants may be regular occupants of the project building, visitors to the building (i.e. customers of a retail establishment), or individuals with no connection to the project building. Composition of the panel in this regard is at the discretion of the project team.

Responses are to be collected via anonymous methods either written or electronic. The Perceived Indoor Air Quality test is considered “passing” if 80% or more of the panel renders the space “acceptable” at each interval. If less than 80% of the panel renders the space “acceptable”, appropriate corrective actions must be implemented to correct the deficiency. Corrective actions must be implemented within six (6) months of the con-clusion of the panel observations.

Subjective evaluation - Questionnaire

The questionnaire is to be designed to address perceived air quality particularly focusing on odors and irritation responses. The responses shall be tabulated. Respondent answers of -1, -2, or -3 on the seven-point scale will be considered as dissatisfied. If more than 20% of respondents are dissatisfied, appropriate corrective actions must be implemented during the performance period.
