Which statement describes IAQP that VRP does not provide?

• A. A performance-based approach to achieve IAQ by selecting ventilation, filtration, and source control tailored to the building.
• B. A fixed minimum outdoor air requirement for all spaces.
• C. A requirement to only use mechanical ventilation.
• D. No filtration requirements.

Answer: (A)

IAQP is a performance-based approach that lets you design for IAQ by selecting ventilation, filtration, and source-control measures tailored to the specific building and its contaminant sources. Instead of just meeting a fixed outdoor-air rate, you identify contaminants of concern, set IAQ targets, and demonstrate that the building design achieves those targets through the chosen combination of ventilation, filtration efficiency, and source-control strategies.

That flexibility is what VRP does not provide. VRP uses prescriptive requirements, like a fixed minimum outdoor air rate for spaces, regardless of the building’s unique contaminants or filtration options. It doesn’t guide you to tailor filtration or source control to the building.

The other statements don’t describe IAQP’s distinguishing feature: IAQP does not require staying with only mechanical ventilation, and filtration is commonly part of IAQP strategies to meet IAQ targets, not something to be avoided.
